12.3 Primary Copper Smelting

2015-9-10 · typical pyrometallurgical copper smelting process, as illustrated in Figure 12.3-1, includes 4steps: roasting, smelting, concentrating, and fire refining. Ore concentration is roasted to reduceimpurities, including sulfur, antimony, arsenic, and lead. The roasted product, calcine, serves as adried and heated charge for the smelting furnace. Smelting of roasted (calcine feed) or unroasted(green feed) ore concentrate produces matte, a molten mixture of copper sulfide (Cu2S), iron sulfide(FeS), and some heavy metals. Converting the matte yields a high-grade "blister" copper, with 98.5 to99.5 percent copper. Typically, blister copper is then fire-refined in an anode furnace, cast into"anodes", and sent to an electrolytic refinery
