    Antimony - Wikipedia

    Most antimony is mined as the sulfide; lower-grade ores are concentrated by froth flotation, while higher-grade ores are heated to 500–600 C, the temperature at which stibnite melts and separates from the gangue minerals. Antimony can be isolated from the crude antimony sulfide by reduction with scrap iron: Sb 2 S 3 + 3 Fe → 2 Sb + 3 FeS
