Antimony production involves hydrometallurgy and pyrometallurgy, the latter being still dominant The conventional extraction of antimony from stibnite and jamesonite involves a two-step pyrometallurgical process comprising volatilization roasting and carbothermal smelting ,...

Extraction of Antimony
Know More

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 ....
