  • 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.
