The largest copper mine in North America (and the world's largest man-made excavation) is the Bingham Canyon Mine near Salt Lake City, Utah. A $1.5 billion modernization program completed in 1998 turned Bingham Canyon into North America's lowest-cost copper producer, a model of operational efficiency and environmental compliance.

Impacts of copper mining on people and nature. The mining industry uses sulphuric acid in the extraction and treatment of copper. The extraction processes are called heap and situ leaching; during these processes, particles react with each other to create acidic mists that not only harm people's skin, eyes and lungs, but also destroy crops, deteriorate the quality of the land, and damage ...

Before the beneficiation of copper ores, crushing and grinding are required. The bulk ores are crushed to about 12cm by a jaw crusher or a cone crusher. Then the crushed materials are sent to the grinding equipment, and the final particle size of the copper ore is reduced to 0.15-0.2mm. Copper ore crushing process. 1.

The old oxide ore treatment plant, along with the old copper smelter, was closed in 1995. The treatment of oxide through leaching, solvent extraction and electrowinning was started by Mantos in 1995. The extraction in the underground mine ended in 1996 and Anglo American acquired almost interest in Mantos Blancos in 2000.
