FIELD: metallurgy. SUBSTANCE: initial powder material is subjected to thermal destruction, using its feeding in central part of plasma reducing medium. Material is fed in amount of no less than stoichiometrically required for its full oxidation. Then carbon-containing reagent is introduced in formed mixture and after separation of wasted gass medium material is fed for additional reduction. In the case, separated gas medium is purified and bring back in process. EFFECT: method to produce metal by reduction is used in metallurgy. 5 cl 1 dwg
