Electrolytic recovery of antimony from natural stibnite ore

Hydrometallurgy, 1996
Abstract Stibnite ore at Wadi Abu Quraiya, situated in the central Eastern Desert of Egypt has been subjected to petrographical, mineralogical, infrared, X-ray diffraction, chemical and spectral analyses. Hydrometallurgical treatment based on leaching with acids, precipitation and electro-deposition of metal values from the ore have been developed ...

Selection on the Process for Removing and Recovering Antimony from Antimonial Refractory Gold Ores

2017
It is well known that the gold ores containing a high content of arsenic and antimony are very refractory. In this paper, the adverse effect of antimony on the extraction of gold by pretreatment-cyanide leaching was discussed in detail. Moreover, these processes of removing and recovering antimony from alkaline sodium sulfide or hydrochloric acid ...
