Extraction of Antimony

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

Metal Extraction Process for High Grade Stibnite of Kharan

A rapid and simple process has been developed for the recovery of antimony metal from stibnite ore of Kharan area (Balochistan) of Pakistan. The ore was characterized by X-ray diffraction (XRD) technique and found to contain 66% stibnite i.e. antimony sulfide (Sb2S3). The process parameters for the extraction of antimony were optimized on laboratory scale by varying reaction temperature from
