A Review on Pyrometallurgical Extraction of Antimony from …
The process consists of heating antimony sulfide in crucibles together with fine iron scrap at slightly more than the stoichiometric amount. Due to the high specific gravity of iron sulfide, it is difficult to completely separate it from metallic antimony; hence, additives may be used. For example, sodium sulfate and carbon are added, to ...
