FIELD: non-ferrous metallurgy, namely procession of sulfide ores and concentrates of heavy non- ferrous metals. SUBSTANCE: method comprises steps of using as a sulfidizing reagent upon reduction-sulfidizing procession of slag of a melting zone in stripping double-zone Vanyukoff's furnace a material, whose content of non-ferrous metal is no less than in an initial metal-containing raw material. Such material may be a concentrate, having a content identical to content of the initial material, solid matte or a concentrate of flotation- separation of copper-nickel converter matte. EFFECT: enhanced efficiency of stripping process.
