The largest copper mine in North America (and the world''s largest manmade excavation) is the Bingham Canyon Mine near Salt Lake City, Ut. A billion modernization program completed in 1998 turned Bingham Canyon into North America''s lowestcost copper producer, a model of operational efficiency and environmental compliance.

Copper processing is a complicated process that begins with mining of the ore (less than 1% copper) and ends with sheets of % pure copper called cathodes, which will ultimately be made into products for everyday most common types of ore, copper oxide and copper sulfide, undergo two different processes, hydrometallurgy and pyrometallurgy, respectively, due to the different ...
EPA also proposes two schedules for completing the Mining Waste Report to Congress—one for completing the report on extraction and beneficiation wastes and one for promulgating a reinterpretation for mineral processing waste. October 31, 1983—EPA misses the statutory deadline for submitting its mining waste Report to Congress.
Copper extraction refers to the methods used to obtain copper from its ores. The conversion of copper consists of a series of physical and electrochemical processes. Methods have evolved and vary with country depending on the ore source, local environmental regulations, and other factors.
