12.3 Primary Copper Smelting

2015-9-10  A typical pyrometallurgical copper smelting process, as illustrated in Figure 12.3-1, 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.

PYROMETALLURGICAL RECOVERY OF COPPER VALUES

In addition, the Zimmerley et al. process, like most pyrometallurgical processes, is conducted in a single stage reactor. An article by Bryk, P. et al., "Flash Smelting of Copper Concentrates," AIME, February 1958, discloses a process wherein copper in flash smelter slags is recovered by holding the slag in an electric furnace for several hours.
