FIELD: non-ferrous metallurgy; processing copper-nickel and copper sludges and other semi-products containing noble metals. SUBSTANCE: proposed method includes autoclave oxidizing leaching of starting products at temperature of 180-220 C and partial pressure of oxygen of 0.4-1.0 Mpa. Concentrate of satellite-metals and silver may selectively separated from solution. Proposed method makes it possible to perform separation of platinoids and non-ferrous metals at one stage of leaching excluding treatment with sulfuric acid at elevated temperature. EFFECT: enhanced efficiency. 2 cl, 2 tbl, 2 ex
