The NaCl-Na 2 CO 3 composite The melting of the additive increases its contact surface with vanadium-bearing minerals increases vanadate generation, and reduces the addition of a single sodium salt. The two synergistic effects significantly increased the vanadium leaching rate. Under the following conditions: m(NaCl):m(Na 2 CO 3 ) = 3:2, calcination temperature of 800℃, calcination time of 3 h, leaching temperature of 70℃, leaching time of 90 min and liquid-solid ratio of 10:1 mL/g, the vanadium leaching rate of NaCl-Na 2 CO 3 composite calcination was 93.84%, which was 4.43% higher than that of single NaCl as the calcination additive. The vanadium leaching process was in accordance with the nuclear contraction model, and the leaching process was controlled by a mixture of chemical reaction and diffusion with an apparent activation energy of 39.81 kJ/mol.
