Chapter 8 Environmental Aspects of Copper Production

Copper Production Copper production is not an environmentally benign activity. From mining and milling through hydro- and pyrometallurgical processing to refin-ing, copper production can have significant ad-verse impacts on air quality, surface and ground-water quality, and the land (see figure 8-1 ). While these impacts can be severe when the ...

Copper extraction - Wikipedia

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.. As in all mining operations, the ore must usually be beneficiated (concentrated).

5.1.1 Copper Ore Mining Copper is commonly extracted from surface, underground and increasingly, from in situ operations. In 2000, the principal mining States, in descending order, Arizona, Utah, New Mexico, and Montana, accounted for 99 percent of domestic production. Copper was also recovered at mines in three other States.

Copper Environmental Profile - Copper Alliance

Primary copper production starts with the extraction of copper-bearing ores. There are two basic ways of copper mining: surface and underground mining. Due to copper being spread in relatively low concentrations over large areas, surface, or open-pit mining, is the predominant mining method for copper in the world.
