FIELD: hydrometallurgy. SUBSTANCE: method includes processing solutions by reducing agents at 80 100 C. First the processing is done by reducing agents up to redox potential within 890 910 MV. The reducing agents are decomposed in the process of interaction with the solution without forming foreign impurities. Then it is worked with salt of bivalent iron up to complete gold precipitation. EFFECT: method allows one to achieve complete and selective gold recovering at minimum contamination of the solution with impurities. 1 dwg, 2 tbl
