Apparatus for the complex continuous processing of polymetallic raw materials

An apparatus for continuously processing complex, non-ferrous metallic compositions comprising a melting chamber for the melting of said compositions and accumulation of the corresponding metal oxides, said melting chamber being provided with means for charging non-ferrous metallic material which is heated to form a melt, and means for removing selected layers of the melt as they stratify according to their specific weights;

• a reducing-sublimating chamber communicating with said melting chamber to reduce and sublime the non-ferrous materials, said reducing-sublimating chamber also communicating with a gas duct and a chamber for condensation of the sublimated metal vapors, the lining of said reducing-sublimating chamber having at least one plasmatron built therein, said plasmatron having a nozzle permanently immersed in the melt adapted to inject thereinto a plasma jet capable of agitating and simultaneously reducing said melt, said reducing-sublimating chamber provided with means for charging coke on the surface of the melt also including an outlet for removing a melted slag, poor in non-ferrous metals.
