FIELD: metallurgy; reduction of metal oxides by carbon-containing agents for obtaining final product at different phase state.
SUBSTANCE: charge in form of mixture of oxides and reductant is fed to heated furnace and is mixed in way of temperature rise at passage of gas mixture through charge in way of temperature rise. Size of particles of oxides does not exceed 2-4 mm. Used as reductant are hydrocarbons and/or oxygen derivatives of hydrocarbons and/or their polymers. Reduction process is completed within range of temperatures of forming final product at preset phase state.
EFFECT: enhanced efficiency of process.
