The imperative of resource recycling and the innocuous processing of HAAD stand as prevalent challenges and pressing priorities. This study introduces an innovative vacuum vaporization-condensation technique, capitalizing on the intrinsic merits of vacuum metallurgy, to synthesize Sb 2 O 3 . ICP analysis evidenced an enhancement in the purity of the Sb 2 O 3 product from an initial 73.96–91.35%, with a concomitant reduction in As impurities from 18.10–6.20%, and residual contaminants approximating 0.17% following a dual-phase vacuum vaporization-condensation process at divergent temperatures. XRD assessments affirmed the feasibility of direct Sb 2 O 3 synthesis via vapor-phase migration and condensate amalgamation, achieving substantial As 2 O 3 impurity diminution. SEM and EPMA observations underscored a homogenous particulate morphology in the refined Sb 2 O 3 . Incomplete As extraction from the refined Sb 2 O 3 product was attributed to the persistence of (As, Sb 2 )O 4.5 , accompanied by partial Sb attrition throughout the fabrication sequence. The suboptimal partitioning efficacy of (As, Sb 2 )O 4.5 warrants further investigation. This methodology underscores its environmental compatibility, characterized by zero gaseous effluent, absence of wastewater expulsion, and elimination of reagent usage, thereby mitigating environmental detriments and paving the way for the sustainable exploitation of HAAD.
