FIELD: metallurgy. SUBSTANCE: stoichiometric mixture of ore materials with reducer is heated in mold by passing electric current and when mixture temperature reaches 0.6-0.8 of melting point of its low-melting component, mixture is compacted. Mixture is reduced in vacuum at pressure of 0.1-10 mm Hg. Reducer is used in form of solid carbon-containing material. Current intensity is maintained constant. Speed of compaction of mixture in course of reduction is maintained invariable and preset by the formula given in the invention description. EFFECT: higher efficiency. 1 dwg
