Abstract
A new technology of one-step leaching of refractory gold concentrate containing arsenic and sulfur was studied and 96.8% of gold was extracted in an hour by this technology. Themodynamic possibility of reactions of arsenopyrite, pyrite and gold with sodium hypochlorite in NaOH medium, and solution chemistry of H3AuO3 at different pH values were analyzed. The reason why the gold wrapped by FeAsS, FeS2 can be leached out rapidly by grnding of porcelain ball mill, is explained.
