Copper in the USA: Copper Producers
2021-7-19 At the beginning of copper's flow through the economy are the mining companies, which process vast quantities of low-grade ore, mostly from open-pit mines in order to produce copper. Approximately two tons of overburden must be removed along with each ton of copper ore. The ratio of overburden to ore is sometimes as high as 5 to 1.
