Copper in the USA: Copper Producers
The ratio of overburden to ore is sometimes as high as 5 to 1. 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 ...Web
