  • 123 Primary Copper Smelting

    A typical pyrometallurgical copper smelting process, as illustrated in Figure 1231, includes 4 steps: roasting, smelting, concentrating, and fire refining Ore concentration is roasted to reduce impurities, including sulfur, antimony, arsenic, and lead The roasted product, calcine, serves as a dried and heated charge for the smelting furnace Smelting of roasted (calcine feed) or unroastedSection 123 Primary Copper Smelting Including the introduction (Chapter 1), this report contains four chapters Chapter 2 gives a description of the secondary copper industry It includes a characterization of the industry, an overview of the different process types, a description of emissions, and a description of the technology used to control emissions resulting from processing zincBACKGROUND REPORT PRIMARY COPPER SMELTING13/01/2021· Copper Smelting Process In the autogenous system described by this report, sulfide concentrate and silica flux are blown into the furnace through a specially designed burner with oxygen and is flash smelted to about 50percent copper matte The matte flows down an inclined crucible, countercurrent to the slag flow, to the converting zone at one end of the furnace Oxygen is introducedCopper Smelting Metallurgist & Mineral Processing
