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.

Изобретение относится к гидрометаллургии благородных металлов, в частности к способам извлечения серебра и золота из сульфидных, окисленных руд, концентратов и материалов хвостохранилищ. Предлагаемый способ заключается в том, что обработку исходных веществ ведут выщелачиванием водными растворами, содержащими ионы тиоцианата и трехвалентного железа, а выделяют серебро и золото пропусканием раствора после очередного цикла выщелачивания через слой железного скрапа или алюминиевых стружек и возврата этого раствора после корректировки на новый цикл.The invention relates to hydrometallurgy of precious metals, in particular to methods for extracting silver and gold from sulfide, oxidized ores, concentrates and materials of tailings. The proposed method consists in the fact that the processing of the starting substances is carried out by leaching with aqueous solutions containing thiocyanate and ferric iron ions, and silver and gold are isolated by passing the solution after the next leaching cycle through a layer of iron scrap or aluminum chips and returning this solution after adjustment for a new cycle.
