FIELD: chemical metallurgy. SUBSTANCE: method involves leaching iron oxide-based sediments containing platinum and palladium in the form of metals and chlorides thereof in acidic-chloride medium, preferably in solutions-commercial products of precious metal production; cementing solved part of platinum metals with metal iron based powder materials. Leaching and cementing processes are carried out simultaneously. EFFECT: intensified production of commercial platinum, palladium and gold from commercial products of precious metal production and reduced consumption of reagents. 4 cl, 5 tbl, 3 ex
