Cao et al. [6] combined leaching and distillation to obtain SbCl3 from lead anode slime. In some works, leaching is also combined with electrodeposition to obtain metallic Sb: Ubaldini et al. [7] recovered metallic antimony from stibnite in a two-step process consisting of mineral leaching and antimony electrowinning.

stibnite, antimony sulfide (Sb 2 S 3 ), the principal ore of antimony. This mineral has a brilliant metallic lustre, is lead- to steel-gray in colour, and fuses readily in a candle flame (at about 525° C [977° F]). It often possesses a bladed habit, is striated, and has one perfect cleavage. Stibnite occurs in massive forms in gneiss and granite.

Antimony (Sb; CASRN ) is a semimetal element with chemical properties similar to lead, arsenic, and bismuth. In nature, it is found associated with sulfur as stibnite. Antimony is used in white metal, a group of alloys having relatively low melting points. White metal usually contains tin, lead, or antimony as the chief component.

In this process, antimony and arsenic were effectively separated to produce cathode metal antimony (> 98%) in a single step. The sulfur present in stibnite was transformed to elemental sulfur remaining in the residue. Therefore, the contamination by large amount of arsenic soda slag and low-concentration SO 2 were avoided. 4. Conclusion
