Antimony trisulfide (Sb2S3) is found in nature as the crystalline mineral stibnite and theSb2Sis precipitated when H2S is passed through an acidified solution of Sb(III).In the extraction of antimony from antimony ores the alkaline sulfide process is employed where Sb2Sreacts to form thioantimonate(III) salts (also
Extraction of antimony trioxide from antimony sulfide ore. USA . Some of the finely divided white precipitate of antimony trioxide or
aqueous hydrogen sulfide are very reactive in their reactions. Naturallyin the electrode vessel, a profuse yellow precipitate of antimony sulfide was formed.
The Sb(V) removal mechanism is sulfate-reduction and sulfide oxidization–precipitation, different from the conventional SRB-precipitation processes for heavy
