extraction of antimony from its ore

Extraction of Antimony

Antimony is extracted mainly from ores containing antimony trisulphide in the form of stibnite. Rich ores are first subjected to liquation, whereby the fusible sulphide is removed from the gangue and concentrated. The concentrate is then reduced to metal by smelting with wrought iron in pots, in reverberatory furnaces or sometimes in blast ...

Antimony - Wikipedia

The extraction of antimony from ores depends on the quality and composition of the ore. 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.
