<p>Starting materials, e.g., copper-zinc or copper-lead--zinc concentrates and also slag-containing zinc and lead, are first melted in an atmosphere of gas containing free oxygen, and the resulting melt is then reduced by means of a gaseous plasma jet formed, for instance, by nitrogen. An apparatus includes one or several plasmatrons whose nozzles are immersed in the melt at a angle to its surface for agitation of said melt by the plasma jet and for reduction of the metal oxides.</p> |
