Method of Producing Metallic Cobalt from Oxide Cobalt-Based Material ABSTRACT A method of producing metallic cobalt from an oxide co- balt-based material which comprises producing a plasma jet by passing a reducing gas through the zone of electric dis- charge, heating the oxide material by the plasma jet to a temperature of about 1450°C to about 1580°C, at which metal- lic cobalt is melted down and cobalt oxides are reduced to metal. The reduction of cobalt oxides to metal is effected in the presence of the reducing gas fed in an amount rang- ing from about 1.15 to about 1.5 times that of the reducing gas required in accordance with stoichiometry. In addition, the method comprises desulphurization of the molten metallic cobalt and its refinement effected by removing gases dis- solved therein. - 1 -
