Zusammenfassung:FIELD: metallurgy. SUBSTANCE: in a method of producing metals via metal sulfide reduction, a layer of sulfide is placed in reaction space under layer of carbon reducing agent, and reduction is carried out under atmosphere of hydrogen regenerated by carbon reducing agent from water steam fed into reaction space from the top of reaction zone. EFFECT: increased sulfide reduction degree and reduced power consumption on reduction. 1 dwg
