This paper outlines the hydrometallurgical processing and the variouspossible approaches for the recovery of metallic antimony from its antimonite sulphide ore by electrolysis. Thermodynamic calculations havebeen made to find the optimum conditions for roasting and/or sulphateroasting of Wadi Abu Quraiya antimonite ore. The antimonite ore (Sb2S3) is roasted directly without concentration and large savings in reagent and chemical processes are expected. A suitable roasting temperature of 1200 K for 4 hours has been determined. Metallic antimony is' cathodically electrodeposited with a high current efficiency at current densities of 350 to 500 A/m(2) depending on the composition of leach liquor solutions. The results of the electron microscopy investigation confirmed by metal value data in the ASTM cards are in good agreement with the chemical analysis.

Abstract

2. This paper outlines the hydrometallurgical processing and the variouspossible
approaches for the recovery of metallic antimony from its antimonite sulphide ore
by electrolysis. Thermodynamic calculations havebeen made to find the optimum
conditions for roasting and/or sulphateroasting of Wadi Abu Quraiya antimonite
ore. The antimonite ore (Sb2S3) is roasted directly without concentration and
large savings in reagent and chemical processes are expected. A suitable
roasting temperature of 1200 K for 4 hours has been determined. Metallic
antimony is' cathodically electrodeposited with a high current efficiency at current
densities of 350 to 500 A/m(2) depending on the composition of leach liquor
solutions. The results of the electron microscopy investigation confirmed by metal
value data in the ASTM cards are in good agreement with the chemical analysis.
