description FIELD: hydrometallurgy. SUBSTANCE: invention relates to methods of vat, heap, and underground leaching of metals from sulfide materials (subquality ores, reject material, and metallurgical enterprises' wastes. Processing is performed with acidic solutions in presence of sodium chloride and ferric compounds with no air access at liquid to solids ratio from 0.17 to 0.33. EFFECT: enlarged resource of metals due to using unmarketable materials. 1 cl, 2 tbl Изобретение относится к гидрометаллургии, а именно к способам чанового, кучного и подземного выщелачивания металлов из сульфидных материалов (некондиционных руд, хвостов обогащения, отходов металлургических предприятий). Предлагаемый способ переработки сульфидных материалов проводят кислыми растворами в присутствии хлорида Na и соединений трехвалентного Fe без доступа воздуха в интервале Ж:Т=0,17:0,33.
