Copper mining in the United States - Wikipedia

Copper mining in the United States has been a major industry since the rise of the northern Michigan copper district in the 1840s. In 2017 the United States produced 1.27 million metric tonnes of copper, worth $8 billion, making it the world's fourth largest copper producer, after Chile, China, and Peru. Copper was produced from 23 mines in the US. Top copper producing states in 2014 were (in descending order) Arizona, Utah, New Mexico, Nevada, and Montana. Minor production also came from Idaho, and Missouri

Copper - FLSmidth

This mechano-chemical process can leach 97-99% copper directly on site, from concentrates as low as 5% copper in less than six hours. This makes it feasible for you to produce cathode copper from concentrate directly at the site rather than to sell the concentrate to a smelter. The ROL process can even leach copper from arsenic-ladden concentrates.
