Abstract
FIELD: hydrometallurgy of noble metals, in particular, methods of extraction of silver and gold from sulfide, oxidized ores, concentrates and materials of tailing dumps. SUBSTANCE: source substances are treated by leaching with aqueous solutions containing ions of thiocyanate and trivalent iron, silver and gold are separated by passing the solution after the next leaching cycle through a layer of iron scrap or aluminium chips and return of this solution after correction to a new cycle. EFFECT: improved technology of silver and gold extraction.
