The ore itself averages less than 0.7 copper in US mines. Copper ore normally is crushed, ground, and concentrated, usually by flotation, to produce a beneficiated ore containing about 25 copper. The ore concentrates are reduced to the metallic state, most often by a pyrometallurgical process.
Copper smelting and classification The smelting of copper Copper that is mined from copper ore, after beneficiation, becomes high quality copper concentrate. Then, after being smelted, refined copper and copper products are yielded. There are two ways of smelting copper, one is pyrometallurgy, the other hydrometallurgical.

Pyrometallurgical techniques use heat to separate copper from copper sulfide ore concentrates. Process steps include mining, concentration, roasting, smelting, converting, and finally fire and electrolytic refining. 12.3.2 Process Description2-4 Mining produces ores with less than 1 percent copper. Concentration is accomplished at the
Copper concentrates are produced by the beneficiation, or upgrading, of copper ore. A typical copper ore would be 0.7 to 2 copper, a typical copper concentrate would grade around 25 to 35 copper. Copper concentrates are either smelted and refined in-house, or sold to custom smelters.
