<p>The invention relates to a method for recovering cobalt and copper from a cobalt-containing copper concentrate in a pyrometallurgical treatment process. Blister copper is formed in a suspension smelter and/or converter, and is conveyed to an anode furnace, and the slag that is formed is fed together with a reductant into a slag cleaning furnace. Blister copper is obtained from the slag cleaning furnace, and this is also routed to the anode furnace to produce anode copper. The slag from the slag cleaning furnace is routed to a cobalt recovery furnace, to which sulphide-containing material is also conveyed, in addition to a reductant. Cobalt is recovered from the cobalt recovery furnace matte and the slag that is formed is waste slag.</p> |
