Abstract
An apparatus for processing complex metallic materials, such as, copper-zinc or copper-lead-zinc concentrates and also slag-containing zinc and lead, by melting these materials in an atmosphere of gas containing free oxygen, and reducing the resulting melt by means of a gaseous plasma jet formed, for instance, by nitrogen. The apparatus includes one or several plasmatrons whose nozzles are immersed in the melt at an angle to its surface for agitation of said melt by the plasma jet and for reduction of the metal oxides.
