Copper mining in the United States

OverviewOre gradesSmeltersBy stateCopper 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 Arizona, Utah, New Mexico, Nevada, and Montana. Minor production also came from Idaho, and Missouri.

Copper Mining and Processing Processing of Copper

Copper Mining and Processing Processing of Copper Ores. Copper processing is a complicated process that begins with mining of the ore (less than 1% copper) and ends with sheets of 99.99% pure copper called cathodes, froth flotation, 2) thickening, 3) smelting, and 4) electrolysis.
