Copper processing or pyrometallurgical processes employ high-temperature chemical reactions to extract copper from its ores and concentrates. Generally, these processes are used with copper sulfides and, in some cases, high-grade oxides. Depending on the copper mineral and the type of equipment, pyrometallurgical recovery may take as many

Mining of copper ores is carried out using one of two methods. Underground mining is achieved by sinking shafts to the appropriate levels and then driving horizontal tunnels, called adits, to reach the ore. Underground mining is, however, relatively expensive and is generally limited to rich ores. El Teniente, in Chile, is the world's largest ...
