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.

Copper Smelting Process - Furnaces Used, By-Products,

2010-4-9  Introduction to Copper Smelting Techniques. Copper ore typically contains only about 0.6% of the actual copper mineral, the most common ore mined being chalcopyrite. The ore is attained using traditional methods of underground and open pit mining, the later accounting for 90% of the ore used in smelting.

What is Copper Extraction?

All primary sulfide ores of copper sulfides, and most concentrates of secondary copper sulfides (being chalcocite), are subjected to smelting. Some vat leach or pressure leach processes exist to solubilise chalcocite concentrates and produce copper cathode from the resulting leachate solution, but this is a minor part of the market.
