In this study, the process of bio-oxidation of flotation concentrate from the flotation of gold-sulfide ores and sorption cyanidation of the bio-oxidation product were analyzed, and the content of dispersed gold in pyrite, arsenopyrite, and carbonaceous matter was determined. The article also presents the results of laboratory studies on the behavior of gold ions at different stages of leaching, analysis of the gold content in solid samples after acid and alkaline treatment, as well as a semi-quantitative elemental composition. The formation of jarosite minerals was studied at high concentrations of chloride ions and on the surface of pyrite and negatively affects the oxidation of pyrite/arsenopyrite.
