Microbial Transformations of Antimony | SpringerLink
Microorganisms have significant effects on Sb speciation and mobility, and the geochemical cycling of Sb is largely driven by microorganisms. Although Sb can exist in the V, III, 0, and –III valence states, antimonate [Sb(V)] and antimonite [Sb(III)] are the two prevalent oxidation states in the natural environment and biota (Filella et al ...

Antimony transformation and mobilization from stibnite by an antimonite
AS-1 is an antimonite-oxidizer isolated from the mine slag in Xikuangshan Sb mine. Whole genome sequencing data showed the presence of sulfur-oxidizing genes, antimony (Sb) metabolism genes and carbon fixation genes in AS-1's genome. In this study, strain AS-1 was verified as an autotrophic Sb(III)-oxidizer.

Chemistry of Antimony (Z=51)
Antimony trisulfide, (Sb_2S_3), is a sulfide mineral commonly called stibnite or antimonite. Antimony trisulfide exists as a gray/black crystalline solid (orthorhombic crystals) and an amorphous red-orange powder. It turns black due to oxidation by air. Antimony trisulfide is the most important source for antimony.
