This paper conducted a summer evaporation experiment on the chloride-type oilfield brine within the Nan Yishan structure in the Chaixi area, and obtained the evaporation and crystallization sequence of the brine, the enrichment patterns of elements, and the loss of elements at each stage under natural conditions. The experimental results are as follows: (1) The salt precipitation rule under natural conditions is: rock salt → gypsum → potassium-sodium mixed salt → Antarctic rock salt; (2) The overall enrichment pattern of elements is: as the evaporation rate increases, sodium, potassium, calcium, magnesium, and boron precipitate in different forms in the solid phase, reaching the corresponding stage, while lithium and bromine are enriched in the liquid phase, and the enrichment multiple of lithium in the final stage is 26.3 times, with a maximum concentration of 5.26 grams per liter; (3) The study found that during the evaporation process, lithium and potassium lose with different degrees of loss, which should take into account the entrainment of the mother liquor in the solid phase and the loss of irregular crystal structure or mineral adsorption during different stages of salinization. Moreover, the loss rate increases with the increase of evaporation loss rate. The experimental results can provide data support for the subsequent comprehensive utilization of oilfield brine, and the next step should be to determine how to avoid the adsorption loss during the evaporation process, so that the brine can be developed and utilized to the greatest extent. oilfield brine evaporation experiment law of salt decomposition Nan Yishan Figures Figure 1 Figure 2 Figure 3 Figure 4 Figure 5 Figure 6 Figure 7 Figure 8 Figure 9 Figure 10 Figure 11 1. Introduction Oilfield brines are rich in high concentrations of ions such as Na + , K + , Ca 2+ , Mg 2+ , CO 3 2− , HCO 3 − , SO 4 2− , and Cl − , as well as some trace elements such as I, Li, B, Fe, and F in different concentrations (Zhao et al.2024). China's oilfield brines are rich in resources and have a long history of development, but there is insufficient research on the comprehensive development and utilisation of oilfield brines (Song et al.2024). They are mainly distributed in provinces such as Qinghai, Xinjiang, Hubei, Sichuan, etc. (Fig. 1 ), and the brine characteristics are different in each region (Mu et al.2016). Located in the Nan Yishan dorsal tectonics in the western part of Qaidam Basin, the type of brine is tectonic fissure pore brine, buried in the ground between 2000m-3000m (Liu et al.2018), the oilfield brine for potassium, boron, lithium, iodine resource-rich areas, the hydrochemical type of the Sulin Classification of the calcium chloride type, the main characteristics of the high mineralisation, high calcium, low magnesium and low sulphate, after evaporation and crystallisation can be obtained potash and lithium, boron, iodine and other multi After evaporation and crystallisation, we can get potassium salt products and multi-element enriched brine such as lithium, boron, iodine, etc (Li et al.2021). The potassium content of the brine reaches the industrial grade, and the trace elements such as lithium and boron reach the lowest industrial grade, while the bromine and iodine content reaches the index of comprehensive utilisation, which is of great value for comprehensive utilization (Han et al.2024). 2. Sampling and Methods 2.1. Sampling The brine samples were taken from the NanYishan in April 2020 (Fig. 2 ), and after the discharge brine flow and temperature were stabilised, the brine was contained in a plastic bucket that had been wetted and washed with brine, and the initial brine physicochemical parameters were recorded. The brine has a pH of 5.65 at 17.5 ℃, and a specifc gravity of 1.192 g/cm 3 . 2.2. Sampling Methods A brine weight of 101.45 kg was selected for the evaporation experiments, which were conducted outdoors at Nan Yishan, and the evaporation lasted 82 days with 28 solid-liquid separations. At each solid-liquid separation, temperature, density, pH, evaporation loss and weight of precipitated salt, humidity and temperature of the evaporation environment were measured. In order to control the water loss rate during the evaporation process, the evaporation vessel was replaced appropriately according to the water depth of not less than 10cm, and the vessel was replaced three times as shown below (Fig. 3 ). Parameters such as temperature, humidity, brine evaporation, and salt precipitation weight were also recorded at the experimental site (Table 1 ).

When a new mineral was observed or after evaporating 3 days, liquid and solid phases in the brine were separated, and the physicochemical properties of the brine were measured. A 25-mL sample of the clarifed solution was removed from the brine into a 250-mL volumetric fask with a flter pipette. The sample was then diluted to determine the composition of the liquid phase with the double deionized water. The salt sample was also analyzed and determined with an Olympus digital polarizing microscope. The liquid samples were numbered after the sequence they sampled, while the solid samples were numbered responding to the liquid samples. The remainder of the brine was put in the tank to continue to evaporate. Repeat as it is mentioned, until the brine evaporates completely (Nie et al.2020). 2.3. Analytical Methods 2.3.1. Major and Trace Elements Analysis The salt mine were heated at 105°C for 24h to remove H 2 O;then, samples were ground to 200 mesh;the brine samples were diluted according to salinity. All samples were sent to the MNR Key Laboratory of Saline Lake Resources and Environment for major and trace element analysis. Major elements Cl − , Na + , K + , SO 4 2− , Mg 2+ , Ca 2+ , and trace elements Li + , B, Br − , Rb + , Cs + were determined in all samples. Na + , K + , Mg 2+ , Ca 2+ , Li + , and B were quantified using an inductively coupled plasma atomic emission spectrometer (ICPE-9000). The concentration of Cl − ion was determined by silver nitrate volumetric titration. The SO 4 2− was analyzed by barium sulfate gravimetric method.SO 4 2− were measured through ion chromatography, and the analytical error was less than 0.2% (Zhang et al.2021). 2.3.2. X-ray Powder Diffraction The salt mine samples were cleaned with ethyl alcohol and heated in an oven at 50 ◦C for 24 h. Then, samples were ground to 200 mesh. After drying, samples were sent to the Powder Crystal Laboratory of the Research Institute of China University of Geosciences (Beijing, China) for X-ray diffraction analysis. The measuring instrument was a Smart Lab9 KW rotating anode ray diffractometer made by Rigaku, Japan. The anode was a Cu target, the scanning angle was 3◦–70◦, and the scanning step was 8◦/min. MDI Jade 6.0 software was used for semi-quantitative analysis of the spectra (Wang et al.2023). 3. Results 3.1.

Minerals precipitated in evaporation process During natural evaporation in summer of Nanyishan deep brine, the minerals precipitated successively as below (Fig. 4 ): (1) Halite (2) Halite + Sylvite (Fig. 5 a) (3) Halite + Carnallite (4) Carnallite + Antarcticite (Fig. 5 b) 4. Discussion 4.1. Crystallization path The oilfield brine of Nan Yishan belongs to chloride-type brine, and its main quantitative elements are Na, K, Cl, SO 4 2− , B 2 O 3 , and Br. In the evaporation experiments, Br and B 2 O 3 do not affect the pre-evaporation behaviour. Combined with the mineral precipitation species and liquid phase ion content distribution can be judged, evaporation pre-selected K + , Na + , Mg 2+ //Cl − - H 2 O (25 ℃) phase diagram (Fig. 6a). Combined with the liquid-phase evaporation route of the Nan Yishan, the brine always has a higher NaCl content in the liquid phase at the beginning of the evaporation, and it is the first to reach saturation precipitation, in the halite phase area and has been in the saturated state. NL-0 is the original halogen point, NL-1 ~ NL-14 is the stage of NaCl precipitation; NL-15 starts to precipitate KCl, NL-15 ~ NL-19 with the continuous evaporation of sylvite, evaporation and crystallisation route to the direction of the sylvite and carnallite co-saturation line, this stage is dominated by NaCl, KCl; NL-19 ~ NL-22 deviate from the evaporation route of sylvite, and this time Mg 2+ is continuously enriched in the liquid phase and Ca 2+ precipitates as hard gypsum. The evaporation route finally did not enter the sylvite phase region, as shown in Fig. NL-25 reaches the boundary between halite and sylvite phase region, forming the above evaporation and crystallisation route (Wang et al.2024; Gao et al.2012; Ma et al.2023). At the late stage of evaporation, Na + , K + , Mg 2+ , Ca 2+ //Cl − -H 2 O (25°C) phase diagram is selected (Fig. 6b). At the early stage of evaporation, the original halogen NL-0 is located in the sylvite phase region, but because the sylvite is not saturated at the early stage, with the evaporation of water, the sylvite gradually reaches saturation and starts to precipitate out. With the continuous precipitation of potash, the brine evaporation route moves along and intersects the direction of the co-saturation line of potash and carnallite, and starts to precipitate carnallite. Thereafter, the liquid-phase evaporation route moves along the direction of G→F, during which the halite, sylvite and carnallite are precipitated at the same time, until it intersects with the E-F line, and begins to enter the Antarctic rock-phase region, and finally to the end of the evaporation. The whole evaporation experiment process is divided into four phases: NaCl, KCl, KCl.MgCl 2 .6H 2 O, and CaCl 2 .6H 2 O.

The concentration and precipitation rule of the main elements From the Fig. 7 a, it can be seen that with the increase of the water loss rate of the brine, the concentration of potassium ions in the liquid phase gradually increased when the water loss rate was between 0-61.35%, and the concentration and enrichment rate of potassium ions was accelerated along with the increase of the water loss rate; while the content of KCl in the solid phase was initially relatively smooth and in a horizontal state, and the source of potassium in the solid phase in the early stage of the analysis might be the entrainment of the mother liquor in the wet solid phase. When the water loss rate exceeded 61.35%, the potassium in the liquid phase reached the maximum value of 23.2g/L; after that, the potassium ion content in the liquid phase decreased linearly, while the KCl content in the solid phase increased sharply at that point, indicating that KCl reached saturation and began to precipitate. When the water loss rate reached 65.96%, the potassium ions in the liquid phase decreased to a minimum, and the potassium in the solid phase reached the maximum value, in which KCl had been saturated. Subsequently, the precipitation of potassium salts in the solid phase became less, and potassium ions in the liquid phase began to be enriched again until the end of the evaporation experiment (Jin et al.2021). From the Fig. 7 b, at the beginning of brine evaporation, the boron in the brine did not reach the saturation state, and was always endowed in the liquid phase, with the evaporation, the boron in the liquid phase was also gradually enriched, while the boron in the solid phase was always in a smooth state. When the water loss rate reaches 63.73%, the B 2 O 3 in the liquid phase suddenly decreases, while the B 2 O 3 content in the solid phase rises sharply, at this time the brine pH is 3.11, boron saturation precipitation (Cui et al.2009). When the water loss rate exceeded 67.96%, the B 2 O 3 in the liquid phase and the solid phase increased simultaneously and reached a great value at the same time, and then the content decreased, indicating that there was a boron precipitation peak at this time (Nie et al.2022). The B 2 O 3 in the liquid phase reached the highest content, 53.5808 g/L, when the evaporation loss rate was 68.11%. Lithium in the solid-liquid phase increases with the increase of water loss rate, and there is no maximum value in the solid-liquid phase (Fig. 7 c). This indicates that lithium is generally not involved in salt precipitation, and is only enriched in the liquid phase with the reduction of brine volume, and the content increases gradually. The lithium in the solid phase may come from the mother liquor entrainment, and the content decreases. Throughout the evaporation process, the brine volume was enriched 91.97 times, while the lithium in the liquid phase was enriched only 33.64 times from 151mg/L to 5080mg/L. It is assumed that the evaporation process occurred during the experiment. It is presumed that the phenomenon of evaporation loss and the high number of solid-liquid separation occurred during the experiment, which led to an increase in the amount of lithium loss, and also included that a portion of the mother liquor would be entrapped in the solid phase, which led to a serious loss of lithium element in the final. Between the water loss rate of 55.02%-67.44%, the lithium entrainment in the solid phase is only 0.03%-0.57%, when the lithium concentration is 4.57–16.75 times; the evaporation loss rate is greater than 67.44% to the end of the evaporation, and the entrainment of lithium in the solid phase increases from 0.57% to 4.11%. Therefore, lithium can be considered to be extracted between 55–67% evaporation loss with less loss. The Mg 2+ in the liquid phase increased with the increase of evaporation loss rate (Fig. 7 d), and when the water loss rate reached 64.95%, its content in the liquid phase reached the maximum value of 14.9 g/L, and then decreased sharply, and at the same time, the magnesium content in the solid phase increased, which indicated that the magnesium reached the saturated precipitation at this time, and precipitated in the form of carnallite during the process of evaporation, and the stage of precipitation was from the evaporation loss rate of 64.95% to the end of evaporation. Combined with XRD, it can be found that the magnesium precipitation stage is synchronous with potassium, and the two are precipitated in the form of carnallite. Due to the process of the actual exploitation of brine, it is not possible to measure the elemental content of the samples at each stage in time, as well as the analysis of the substance of the precipitated salt, so it is summarised that the gravity corresponding to the precipitated minerals at each stage is easier to derive from the gravity test (Fig. 8), and it is possible to know the stage of evaporation according to the specific data to provide convenience for the development and exploitation (Nie et al.2013). Summarised as follows: ① gravity > 1.22g/cm 3 ,NaCl ② gravity > 1.27g/cm 3 ,KCl ③ gravity > 1.37g/cm 3 ,KCl.MgCl 2 .6H 2 O ④gravity > 1.27g/cm 3 , CaCl 2 .6H 2 O Figure 8 Plot of elemental enrichment patterns during evaporation 4.3. The relationship between gravity and density as a function of water loss rate It can be seen from Fig. 9 that in the evaporation process of Nan Yishan oilfield brine, the pH value always decreased, while the density always increased. There is a negative correlation between the two. In the early stage of evaporation, the changes between the two were relatively gentle. With the increase in the evaporation loss rate, their change rate increased gradually (Zhang et al.2023; Li et al.2011). 4.4. The lost of main elements in the evaporation phase According to the material balance calculation (Table 4 ), the main ones involved in the precipitation are potassium sodium calcium magnesium and boron, and the final solid sample obtained 8.415kg of sodium with a yield of 99.56%; 474.808g of potassium with a yield of 66.24%; 122.721g of magnesium with a yield of 85.8%; 696.205g of calcium with a yield of 51.68%; and 113.824g of boron with a yield of 27.93%. For the lithium not involved in the precipitation of salt minerals in the liquid phase 4.701g, liquid phase enrichment rate of 32.49%.

(2) Loss of lithium: Lithium is not involved in the precipitation of salts, so it is always in the liquid phase, with an enrichment rate of 32.49% in the liquid phase. During the evaporation process, 5.183 g of lithium was harvested from the solid sample, which was entrained in the solid phase, with an entrainment rate of 40.18%, 11.42% in the halite, 11.55% in the carnallite; and 17.22% in the antarcticite. Solid phase entrapment rate = mass in solid phase at each stage/total amount of original brine*100 Liquid phase enrichment ratio = mass of brine at the end of evaporation/total amount of initial brine*100 In summary, the observation of the solid phase particles in each phase by polarised light microscopy revealed that in addition to the already identified presence of NaCl, KCl and carnallite (Fig. 10 ), other different minerals existed, but due to the low content and the inability to determine the specific mineral composition; and the generation of lithium minerals was not detected, but chemical analyses of the solid phase showed that each solid phase sample contained a certain amount of lithium, which was basically in the form of lithium that is lost when precipitating from the solid phase The lithium was basically lost in the form of entrapment in the mother liquor when the solid phase was precipitated. In addition, researchers from Tianjin University of Science and Technology used microscopic Raman to prove that boron was present in liquid inclusions in the solid phase precipitated from the potassium salt mixing stage of the brine of the Ginel Salt Lake in Xitai, and solid-state characterisation by XPS to determine the ratio of Li, K, Mg, and boron on the surface of the solid phase in the various stages of boiling evaporation and isothermal equilibrium, and through the combined application of optical microscopy, polarized light microscopy, SEM, XPS, and EDS, three loss pathways in the migration of resource elements in the solid phase were identified, such as mother liquor entrapment and crystal surface adsorption. Through the combined application of optical microscopy, polarised light microscopy, SEM, XPS and EDS, it was determined that there are three loss pathways in the migration process of the resource elements in the solid phase, such as inclusions, entrapment in the mother liquor and adsorption on the crystal surface (Zhao et al.2022). Combined with study can be seen, NaCl, KCl, as well as Na 2 SO 4 will adsorb lithium ions, so consider that the adsorption of lithium by NaCl, and KCl affects the lithium solid-phase entrainment, which results in lithium loss (Ma et al.2023). 4.5. Material balance Brine evaporation salt process must not be small is the final material balance, which is the theoretical yield, theoretical dosage and actual yield, dosage comparison between the normal deviation is allowed to exist (error is allowed to ± 5%), in order to prevent the evaporation process to produce errors or anomalies that affect product quality. In evaporation experiments, the amount of salt precipitated by deposition and the amount of salt consumed in the collection of water samples can be calculated and controlled, while the invisible loss refers to the part that is difficult to calculate and quantitatively control. This part of the loss is experimental and production activities should try to avoid and basically stable, such as abnormalities must be identified. The invisible losses in this experiment were mainly caused by losses from daily monitoring, solid-liquid separation and elemental analysis (Table 5 ).

In the evaporation experiment, the salt in the brine has four destinations: precipitation of salt minerals, storage in the liquid phase, sampling loss and loss in solid-liquid separation. Because the purpose of the small-scale evaporation experiment is to study the salt precipitation law during the evaporation process, as well as the concentration of each ion in the solid-liquid phase, changes in the degree of enrichment, so the solid-liquid separation is carried out for a fixed period of time, and the solid-liquid samples are taken separately for chemical analyses (Wang et al.2023). The main routes for the major ions are: into the solid phase or into the liquid phase (depending on the chemical properties of the ions, those that readily form salts are precipitated as solids and those that do not readily form minerals are present in the mother liquor), consumption of samples, and other losses (loss of solids-liquid separation and part of the mother liquor carried away by the wet solid phase). The salt precipitation, the liquid phase and the 25 ml portion of the sample can be quantitatively calculated from the chemical analysis results, while the other losses are calculated according to the difference and subtraction method. Water loss rate: the percentage of water evaporated in the original brine during evaporation experiment. Water loss rate = mass of water lost during evaporation/mass of original brine × 100%. Halogenation rate: The percentage of the mass of the remaining liquid phase in the original brine during the evaporation experiment. Halogenation rate = mass of remaining liquid phase during evaporation/mass of original brine × 100%. Salt precipitation rate: the percentage of precipitated solid phase in the original brine during each separation stage of the evaporation process. Salt precipitation rate = Sum of the mass of wet solid phase after each evaporation separation/mass of original brine× 100%. Loss rate: In evaporation experiments, in addition to the mass of the incoming liquid sample, the solids precipitated, and the evaporated water, the percentage of remaining loss. Loss rate = Sum of the mass of lose after each evaporation separation/mass of original brine× 100%. Water loss rate + Halogenation rate + Salt precipitation rate + Loss rate = 100% [17] Combined with the data in the table, water loss rate, salt precipitation rate, halogenation rate and the rate of loss add up to 100% in the process of evaporation experiments. This conforms to the conservation of material at all stages of the natural evaporation process, while the error of other loss rates in the graphs for each solid-liquid separation is maintained between ± 5%, making the data from this experiment reliable (Fig. 11 ). 5. Conclusions (1) The samples were chloride-type brine from Nan Yishan, and the evaporation and crystallisation route was NaCl→ NaCl + KCl→ NaCl + KCl.MgCl 2 .6H 2 O→ CaCl 2 .6H 2 O. Boron begins to precipitate out of the mineral after the water loss rate > 65%. Li, Br are always concentrated and enriched in the process of evaporation of brine, and are not precipitated in the form of salt minerals. (2) Potassium and lithium are mainly lost in the form of mother liquor entrainment during evaporation with the precipitation of the solid phase, and the amount of lithium lost during evaporation is increasing. The loss of potassium and lithium during evaporation is mainly in the form of entrainment from the mother liquor with the precipitation of the solid phase, and the loss of lithium during evaporation is increasing. (3) The field salt field experiment of this brine has a particularly long sodium chloride precipitation stage throughout the entire evaporation process, and other elements are easily entrained and lost in the sodium salt, resulting in the brine halogenation rate as well as the salt precipitation rate being affected, and therefore conditions are optimised in the subsequent field salt field design to maximise the yield of each element. Therefore, shortening the crystallisation cycle of oilfield brine rock salt, reducing the loss of elements during the test process and increasing the salt yield are key issues. (4) In the process of comprehensive utilisation of brine in other salt lakes in China, the most traditional way is to dry brine in the salt field, where the brine is evaporated to the corresponding stage according to the law of salt precipitation and then extracted to different degrees. According to the calculation of the material balance of the salt field, the loss process of lithium and potassium is understood and improved in the subsequent stages. For example, the Xidai and Zabuye brines both add the raw brine again to the salt ponds at the end of the previous sunning to leach out the lithium and potassium stored in the previous wave of salts.

At each solid-liquid separation, temperature, density, pH, evaporation loss and weight of precipitated salt, humidity and temperature of the evaporation environment were measured. In order to control the water loss rate during the evaporation process, the evaporation vessel was replaced appropriately according to the water depth of not less than 10cm, and the vessel was replaced three times as shown below (Fig.\u0026nbsp;\u003cspan refid=\"Fig3\" class=\"InternalRef\"\u003e3\u003c/span\u003e). Parameters such as temperature, humidity, brine evaporation, and salt precipitation weight were also recorded at the experimental site (Table\u0026nbsp;\u003cspan refid=\"Tab1\"

the brine and the precipitated salts, if there were any, was examined daily. When a new mineral was observed or after evaporating 3 days, liquid and solid phases in the brine were separated, and the physicochemical properties of the brine were measured. A 25-mL sample of the clarifed solution was removed from the brine into a 250-mL volumetric fask with a flter pipette. The sample was then diluted to determine the composition of the liquid phase with the double deionized water. The salt sample was also analyzed and determined with an Olympus digital polarizing microscope. The liquid samples were numbered after the sequence they sampled, while the solid samples were numbered responding to the liquid samples. The remainder of the brine was put in the tank to continue to evaporate. Repeat as it is mentioned, until the brine evaporates completely (Nie et al.2020).\u003c/p\u003e\u003c/div\u003e\u003cdiv id=\"Sec5\" class=\"Section2\"\u003e\u003ch2\u003e2.3.

The evaporation route finally did not enter the sylvite phase region, as shown in Fig. NL-25 reaches the boundary between halite and sylvite phase region, forming the above evaporation and crystallisation route (Wang et al.2024; Gao et al.2012; Ma et al.2023).\u003c/p\u003e\u003cp\u003eAt the late stage of evaporation, Na\u003csup\u003e+\u003c/sup\u003e, K\u003csup\u003e+\u003c/sup\u003e, Mg\u003csup\u003e2+\u003c/sup\u003e, Ca\u003csup\u003e2+\u003c/sup\u003e//Cl\u003csup\u003e\u0026minus;\u003c/sup\u003e-H\u003csub\u003e2\u003c/sub\u003eO (25\u0026deg;C) phase diagram is selected (Fig.\u0026nbsp;6b). At the early stage of evaporation, the original halogen NL-0 is located in the sylvite phase region, but because the sylvite is not saturated at the early stage, with the evaporation of water, the sylvite gradually reaches saturation and starts to precipitate out. With the continuous precipitation of potash, the brine evaporation route moves along and intersects the direction of the co-saturation line of potash and carnallite, and starts to precipitate carnallite. Thereafter, the liquid-phase evaporation route moves along the direction of G\u0026rarr;F, during which the halite, sylvite and carnallite are precipitated at the same time, until it intersects with the E-F line, and begins to enter the Antarctic rock-phase region, and finally to the end of the evaporation. The whole evaporation experiment process is divided into four phases: NaCl, KCl, KCl.MgCl\u003csub\u003e2\u003c/sub\u003e.6H\u003csub\u003e2\u003c/sub\u003eO, and CaCl\u003csub\u003e2\u003c/sub\u003e.6H\u003csub\u003e2\u003c/sub\u003eO. \u003c/p\u003e\u003cp\u003e\u003cb\u003eFigure\u0026nbsp;6\u003c/b\u003e Crystallization path of experimental brine in quaternary water\u0026ndash;salt system metastable phase diagram. \u003cb\u003ea\u003c/b\u003e Trace of liquid point in Na\u003csup\u003e+\u003c/sup\u003e, K\u003csup\u003e+\u003c/sup\u003e, Mg\u003csup\u003e2+\u003c/sup\u003e∥Cl\u0026ndash;H\u003csub\u003e2\u003c/sub\u003eO (25℃) phase diagram. \u003cb\u003eb\u003c/b\u003e Trace of liquid point in Na\u003csup\u003e+\u003c/sup\u003e, K\u003csup\u003e+\u003c/sup\u003e, Ca\u003csup\u003e2+\u003c/sup\u003e, Mg\u003csup\u003e2+\u003c/sup\u003e∥Cl\u0026ndash;H\u003csub\u003e2\u003c/sub\u003eO (25℃)phase diagram\u003c/p\u003e\u003c/div\u003e\u003cdiv id=\"Sec13\" class=\"Section2\"\u003e\u003ch2\u003e4.2. The concentration and precipitation rule of the main elements\u003c/h2\u003e\u003cp\u003e\u003c/p\u003e\u003cp\u003eFrom the Fig.\u0026nbsp;\u003cspan refid=\"Fig6\" class=\"InternalRef\"\u003e7\u003c/span\u003ea, it can be seen that with the increase of the water loss rate of the brine, the concentration of potassium ions in the liquid phase gradually increased when the water loss rate was between 0-61.35%, and the concentration and enrichment rate of potassium ions was accelerated along with the increase of the water loss rate; while the content of KCl in the solid phase was initially relatively smooth and in a horizontal state, and the source of potassium in the solid phase in the early stage of the analysis might be the entrainment of the mother liquor in the wet solid phase. When the water loss rate exceeded 61.35%, the potassium in the liquid phase reached the maximum value of 23.2g/L; after that, the potassium ion content in the liquid phase decreased linearly, while the KCl content in the solid phase increased sharply at that point, indicating that KCl reached saturation and began to precipitate. When the water loss rate reached 65.96%, the potassium ions in the liquid phase decreased to a minimum, and the potassium in the solid phase reached the maximum value, in which KCl had been saturated. Subsequently, the precipitation of potassium salts in the solid phase became less, and potassium ions in the liquid phase began to be enriched again until the end of the evaporation experiment (Jin et al.2021).\u003c/p\u003e\u003cp\u003eFrom the Fig.\u0026nbsp;\u003cspan refid=\"Fig6\" class=\"InternalRef\"\u003e7\u003c/span\u003eb, at the beginning of brine evaporation, the boron in the brine did not reach the saturation state, and was always endowed in the liquid phase, with the evaporation, the boron in the liquid phase was also gradually enriched, while the boron in the solid phase was always in a smooth state. When the water loss rate reaches 63.73%, the B\u003csub\u003e2\u003c/sub\u003eO\u003csub\u003e3\u003c/sub\u003e in the liquid phase suddenly decreases, while the B\u003csub\u003e2\u003c/sub\u003eO\u003csub\u003e3\u003c/sub\u003e content in the solid phase rises sharply, at this time the brine pH is 3.11, boron saturation precipitation (Cui et al.2009). When the water loss rate exceeded 67.96%, the B\u003csub\u003e2\u003c/sub\u003eO\u003csub\u003e3\u003c/sub\u003e in the liquid phase and the solid phase increased simultaneously and reached a great value at the same time, and then the content decreased, indicating that there was a boron precipitation peak at this time (Nie et al.2022). The B\u003csub\u003e2\u003c/sub\u003eO\u003csub\u003e3\u003c/sub\u003e in the liquid phase reached the highest content, 53.5808 g/L, when the evaporation loss rate was 68.11%.\u003c/p\u003e\u003cp\u003eLithium in the solid-liquid phase increases with the increase of water loss rate, and there is no maximum value in the solid-liquid phase (Fig.\u0026nbsp;\u003cspan refid=\"Fig6\" class=\"InternalRef\"\u003e7\u003c/span\u003ec). This indicates that lithium is generally not involved in salt precipitation, and is only enriched in the liquid phase with the reduction of brine volume, and the content increases gradually. The lithium in the solid phase may come from the mother liquor entrainment, and the content decreases. Throughout the evaporation process, the brine volume was enriched 91.97 times, while the lithium in the liquid phase was enriched only 33.64 times from 151mg/L to 5080mg/L. It is assumed that the evaporation process occurred during the experiment. It is presumed that the phenomenon of evaporation loss and the high number of solid-liquid separation occurred during the experiment, which led to an increase in the amount of lithium loss, and also included that a portion of the mother liquor would be entrapped in the solid phase, which led to a serious loss of lithium element in the final. Between the water loss rate of 55.02%-67.44%, the lithium entrainment in the solid phase is only 0.03%-0.57%, when the lithium concentration is 4.57\u0026ndash;16.75 times; the evaporation loss rate is greater than 67.44% to the end of the evaporation, and the entrainment of lithium in the solid phase increases from 0.57% to 4.11%. Therefore, lithium can be considered to be extracted between 55\u0026ndash;67% evaporation loss with less loss.\u003c/p\u003e\u003cp\u003eThe Mg\u003csup\u003e2+\u003c/sup\u003e in the liquid phase increased with the increase of evaporation loss rate (Fig.\u0026nbsp;\u003cspan refid=\"Fig6\" class=\"InternalRef\"\u003e7\u003c/span\u003ed), and when the water loss rate reached 64.95%, its content in the liquid phase reached the maximum value of 14.9 g/L, and then decreased sharply, and at the same time, the magnesium content in the solid phase increased, which indicated that the magnesium reached the saturated precipitation at this time, and precipitated in the form of carnallite during the process of evaporation, and the stage of precipitation was from the evaporation loss rate of 64.95% to the end of evaporation. Combined with XRD, it can be found that the magnesium precipitation stage is synchronous with potassium, and the two are precipitated in the form of carnallite.\u003c/p\u003e\u003cp\u003eDue to the process of the actual exploitation of brine, it is not possible to measure the elemental content of the samples at each stage in time, as well as the analysis of the substance of the precipitated salt, so it is summarised that the gravity corresponding to the precipitated minerals at each stage is easier to derive from the gravity test (Fig.\u0026nbsp;8), and it is possible to know the stage of evaporation according to the specific data to provide convenience for the development and exploitation (Nie et al.2013).

liquid phase enrichment rate is 56.75%, solid precipitation has not been reached, so the potassium in the solid phase is entrained in the brine mother liquor, the solid phase entrainment rate is 13.61%, the unspecified loss rate is 29.64%; ②carnallite: potassium is precipitated in the form of carnallite, the solid phase yield is 44.42%; ③antarcticite: potassium is continuously precipitation, solid phase yield 8.6%, liquid phase enrichment rate 3.5%.\u003c/p\u003e\u003cp\u003e(2) Loss of lithium: Lithium is not involved in the precipitation of salts, so it is always in the liquid phase, with an enrichment rate of 32.49% in the liquid phase. During the evaporation process, 5.183 g of lithium was harvested from the solid sample, which was entrained in the solid phase, with an entrainment rate of 40.18%, 11.42% in the halite, 11.55% in the carnallite; and 17.22% in the antarcticite.\u003c/p\u003e\u003cp\u003eSolid phase entrapment rate\u0026thinsp;=\u0026thinsp;mass in solid phase at each stage/total amount of original brine*100\u003c/p\u003e\u003cp\u003eLiquid phase enrichment ratio\u0026thinsp;=\u0026thinsp;mass of brine at the end of evaporation/total amount of initial brine*100\u003c/p\u003e\u003cp\u003e\u003c/p\u003e\u003cp\u003eIn summary, the observation of the solid phase particles in each phase by polarised light microscopy revealed that in addition to the already identified presence of NaCl, KCl and carnallite (Fig.\u0026nbsp;\u003cspan refid=\"Fig8\" class=\"InternalRef\"\u003e10\u003c/span\u003e), other different minerals existed, but due to the low content and the inability to determine the specific mineral composition; and the generation of lithium minerals was not detected, but chemical analyses of the solid phase showed that each solid phase sample contained a certain amount of lithium, which was basically in the form of lithium that is lost when precipitating from the solid phase The lithium was basically lost in the form of entrapment in the mother liquor when the solid phase was precipitated.\u003c/p\u003e\u003cp\u003eIn addition, researchers from Tianjin University of Science and Technology used microscopic Raman to prove that boron was present in liquid inclusions in the solid phase precipitated from the potassium salt mixing stage of the brine of the Ginel Salt Lake in Xitai, and solid-state characterisation by XPS to determine the ratio of Li, K, Mg, and boron on the surface of the solid phase in the various stages of boiling evaporation and isothermal equilibrium, and through the combined application of optical microscopy, polarized light microscopy, SEM, XPS, and EDS, three loss pathways in the migration of resource elements in the solid phase were identified, such as mother liquor entrapment and crystal surface adsorption. Through the combined application of optical microscopy, polarised light microscopy, SEM, XPS and EDS, it was determined that there are three loss pathways in the migration process of the resource elements in the solid phase, such as inclusions, entrapment in the mother liquor and adsorption on the crystal surface (Zhao et al.2022). Combined with study can be seen, NaCl, KCl, as well as Na\u003csub\u003e2\u003c/sub\u003eSO\u003csub\u003e4\u003c/sub\u003e will adsorb lithium ions, so consider that the adsorption of lithium by NaCl, and KCl affects the lithium solid-phase entrainment, which results in lithium loss (Ma et al.2023).\u003c/p\u003e\u003c/div\u003e\u003cdiv id=\"Sec16\" class=\"Section2\"\u003e\u003ch2\u003e4.5.

In evaporation experiments, the amount of salt precipitated by deposition and the amount of salt consumed in the collection of water samples can be calculated and controlled, while the invisible loss refers to the part that is difficult to calculate and quantitatively control. This part of the loss is experimental and production activities should try to avoid and basically stable, such as abnormalities must be identified. The invisible losses in this experiment were mainly caused by losses from daily monitoring, solid-liquid separation and elemental analysis (Table\u0026nbsp;\u003cspan refid=\"Tab5\"

Because the purpose of the small-scale evaporation experiment is to study the salt precipitation law during the evaporation process, as well as the concentration of each ion in the solid-liquid phase, changes in the degree of enrichment, so the solid-liquid separation is carried out for a fixed period of time, and the solid-liquid samples are taken separately for chemical analyses (Wang et al.2023).\u003c/p\u003e\u003cp\u003eThe main routes for the major ions are: into the solid phase or into the liquid phase (depending on the chemical properties of the ions, those that readily form salts are precipitated as solids and those that do not readily form minerals are present in the mother liquor), consumption of samples, and other losses (loss of solids-liquid separation and part of the mother liquor carried away by the wet solid phase).

Li, Br are always concentrated and enriched in the process of evaporation of brine, and are not precipitated in the form of salt minerals.\u003c/p\u003e\u003cp\u003e(2) Potassium and lithium are mainly lost in the form of mother liquor entrainment during evaporation with the precipitation of the solid phase, and the amount of lithium lost during evaporation is increasing. The loss of potassium and lithium during evaporation is mainly in the form of entrainment from the mother liquor with the precipitation of the solid phase, and the loss of lithium during evaporation is increasing.\u003c/p\u003e\u003cp\u003e(3) The field salt field experiment of this brine has a particularly long sodium chloride precipitation stage throughout the entire evaporation process, and other elements are easily entrained and lost in the sodium salt, resulting in the brine halogenation rate as well as the salt precipitation rate being affected, and therefore conditions are optimised in the subsequent field salt field design to maximise the yield of each element. Therefore, shortening the crystallisation cycle of oilfield brine rock salt, reducing the loss of elements during the test process and increasing the salt yield are key issues.\u003c/p\u003e\u003cp\u003e(4) In the process of comprehensive utilisation of brine in other salt lakes in China, the most traditional way is to dry brine in the salt field, where the brine is evaporated to the corresponding stage according to the law of salt precipitation and then extracted to different degrees. According to the calculation of the material balance of the salt field, the loss process of lithium and potassium is understood and improved in the subsequent stages.

This paper conducted a summer evaporation experiment on the chloride-type oilfield brine within the Nan Yishan structure in the Chaixi area, and obtained the evaporation and crystallization sequence of the brine, the enrichment patterns of elements, and the loss of elements at each stage under natural conditions. The experimental results are as follows: (1) The salt precipitation rule under natural conditions is: rock salt \u0026rarr; gypsum \u0026rarr; potassium-sodium mixed salt \u0026rarr; Antarctic rock salt; (2) The overall enrichment pattern of elements is: as the evaporation rate increases, sodium, potassium, calcium, magnesium, and boron precipitate in different forms in the solid phase, reaching the corresponding stage, while lithium and bromine are enriched in the liquid phase, and the enrichment multiple of lithium in the final stage is 26.3 times, with a maximum concentration of 5.26 grams per liter; (3) The study found that during the evaporation process, lithium and potassium lose with different degrees of loss, which should take into account the entrainment of the mother liquor in the solid phase and the loss of irregular crystal structure or mineral adsorption during different stages of salinization. Moreover, the loss rate increases with the increase of evaporation loss rate. The experimental results can provide data support for the subsequent comprehensive utilization of oilfield brine, and the next step should be to determine how to avoid the adsorption loss during the evaporation process, so that the brine can be developed and utilized to the greatest extent.\u003c/p\u003e","manuscriptTitle":"Element enrichment and loss of chloride-type oilfield brine under natural evaporation conditions in summer","msid":"","msnumber":"","nonDraftVersions":[{"code":1,"date":"2025-11-17 17:35:58","doi":"10.21203/rs.3.rs-7998159/v1","editorialEvents":[{"type":"communityComments","content":0},{"type":"decision","content":"Revision requested","date":"2026-01-06T14:24:16+00:00","index":"","fulltext":""},{"type":"editorInvitedReview","content":"","date":"2026-01-03T13:06:21+00:00","index":"hide","fulltext":""},{"type":"reviewerAgreed","content":"119030752883856070713047107126808239020","date":"2025-12-30T08:26:09+00:00","index":"hide","fulltext":""},{"type":"editorInvitedReview","content":"","date":"2025-12-08T20:56:03+00:00","index":"hide","fulltext":""},{"type":"reviewerAgreed","content":"255335935886158539187048765120443630614","date":"2025-11-22T19:53:45+00:00","index":"hide","fulltext":""},{"type":"reviewerAgreed","content":"42617569228313346559008527367244132774","date":"2025-11-11T08:52:49+00:00","index":"hide","fulltext":""},{"type":"reviewersInvited","content":"","date":"2025-11-06T03:33:15+00:00","index":"","fulltext":""},{"type":"editorAssigned","content":"","date":"2025-11-06T03:24:22+00:00","index":"","fulltext":""},{"type":"checksComplete","content":"","date":"2025-11-01T09:59:10+00:00","index":"","fulltext":""},{"type":"submitted","content":"Carbonates and Evaporites","date":"2025-10-31T11:44:46+00:00","index":"","fulltext":""}],"status":"published","journal":{"display":true,"email":"[email protected]","identity":"carbonates-and-evaporites","isNatureJournal":false,"hasQc":true,"allowDirectSubmit":false,"externalIdentity":"caev","sideBox":"Learn more about [Carbonates and Evaporites](http://link.springer.com/journal/13146)","snPcode":"13146","submissionUrl":"https://submission.nature.com/new-submission/13146/3","title":"Carbonates and Evaporites","twitterHandle":"","acdcEnabled":true,"dfaEnabled":true,"editorialSystem":"em","reportingPortfolio":"Springer Hybrid","inReviewEnabled":true,"inReviewRevisionsEnabled":false}}],"origin":"","ownerIdentity":"849b2ce7-b33c-456d-942c-44a816e56dd4","owner":[],"postedDate":"November 17th, 2025","published":true,"recentEditorialEvents":[],"rejectedJournal":[],"revision":"","amendment":"","status":"published-in-journal","subjectAreas":[],"tags":[],"updatedAt":"2026-03-16T16:16:47+00:00","versionOfRecord":{"articleIdentity":"rs-7998159","link":"https://doi.org/10.1007/s13146-026-01248-8","journal":{"identity":"carbonates-and-evaporites","isVorOnly":false,"title":"Carbonates and Evaporites"},"publishedOn":"2026-03-11 16:00:20","publishedOnDateReadable":"March 11th, 2026"},"versionCreatedAt":"2025-11-17 17:35:58","video":"","vorDoi":"10.1007/s13146-026-01248-8","vorDoiUrl":"https://doi.org/10.1007/s13146-026-01248-8","workflowStages":[]},"version":"v1","identity":"rs-7998159","journalConfig":"researchsquare"},"__N_SSP":true},"page":"/article/[identity]/[[...version]]","query":{"redirect":"/article/rs-7998159","identity":"rs-7998159","version":["v1"]},"buildId":"8U1c8b4HqxoKbykW_rLl7","isFallback":false,"isExperimentalCompile":false,"dynamicIds":[84888],"gssp":true,"scriptLoader":[]}
