FIELD: nonferrous metallurgy; applicable in processing of oxidized nickel-cobalt ores and products of their concentration. SUBSTANCE: method includes hydrosulfiding and recovery of metal sulfides produced by flotation. Ore prior to hydrosulfiding is sintered with reducer. Produced cake is subjected to wet sintered with reducer. Produced cake is subjected to wet grinding in presence with elementary sulfur and sodium sulfite, and obtained pulp is directed to autoclave for hydrosulfiding. EFFECT: provided high recovery of nonferrous metals and their deep separation from iron. 2 tbl, 3 ex
