FIELD: metallurgy.
SUBSTANCE: procedure consists in supply of reaction charge containing composition of produced metal and metal-reducer into reaction zone and in heating charge for metal reduction. Also reaction charge is supplied into the reaction zone of an internal cavity of a graphite electrode corresponding to an anode. Metal thermal reduction is first made inside the electrode. Further, charge is transferred and at its exit to an end of the electrode into the zone of arcing plasma-chemical and electro-chemical metal reduction is continued forming bath of liquid metal and slag. After that liquid metal is cooled at the crystalliser corresponding to a cathode. The device consists of a case, of a mechanical device supplying charge containing produced metal and metal-reducer, of a hopper and of a branch for exhaustion and for supply of inert gas. The device is equipped with the crystalliser, connected to a negative pole and corresponding to a cathode, and with the electrode connected to a positive pole and corresponding to an anode. The graphite electrode has a central orifice and an internal cavity for reduction and transfer of charge. The mechanical device is positioned inside the hopper.
EFFECT: increased rate of process and purity of produced metal.
