摘要：A method of oxygen-smelting copper sulfide concentrate to obtain white metal,nearly white metal matte or blister copper by removing most of the Fe in the copper
sulfide concentrate into the slag as well as removing part or most of the S therein asSOwherein oxygen-smelting is carried out to produce; slag in which a weight ratio of CaOto (SiO+CaO) is 0.3 to 0.6 and a weight ratio of Fe to (FeOx+SiO+CaO) is 0.2 to 0.5, andwhite metal, nearly white metal matte or blister copper, by adding SiOmaterial and CaOmaterial to the copper sulfide concentrate as flux.
