FIELD: metallurgy.
SUBSTANCE: invention refers to bio hydrometallurgical process of extraction of gold out of complex sulphide concentrates containing pirrotin, arseno pyrite, pyrite, and antimonite. The association of microorganisms consists of Sulfobacillus olympiadicus BKM B-2420 D, Ferroplasma acidiphilum BKM B-2421 D, Ferroplasma acidiphilum BKM B-2422 D, and Leptospirillum ferrooxidans BKM B-2423 D. The association of microorganisms is extracted out of working industrial reactors of gold extracting factory and is designed for oxidation of a sulphide gold containing concentrate. The association of microorganisms combines ferrooxiding, sulphuroxiding and sulphideoxiding properties, appeared simultaneously at oxidation of all sulphide compounds of commercial ore concentrate.
EFFECT: facilitates increased activity and expanding of process capabilities of association.
