leaching of gold from refractory gold concentrate was investigated. Mineralogical studies on the concentrate showed that very fine gold grains(<10 μm) were encapsulated in pyrite and arsenopyrite..., and As contents were reduced to approximately 19.8 wt%, 6.97 wt%, and 0.13 wt%, respectively. Ammoniacal thiosulfate was used for gold extraction from the biooxidation residue of the refractory gold concentrate......
