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 ...
Ores that contain copper in the U.S. are typically mined in large, open-pits. Copper processing facilities are usually located near mining or extraction sites. Significant waste volumes are associated with copper production. Mine wastes may contain radionuclides due to their natural presence in ores and can be a source of TENORM.

Although basic porphyry copper flotation and metallurgy has remained virtually the same for many years, the processing equipment as well as design of the mills has continually been improved to increase production while reducing operating and maintenance costs. Also, considerable attention is paid to automatic sensing devices and automatic controls in order to assure maximum metallurgy and ...
The original design for the processing plant involved ore from the mine being conveyed to a 150t surge bin before grinding in a fully autogenous mill. This mill was converted during 2005 to semi-autogenous, allowing the plant to handle harder ore as well as increasing the plant throughput to around 1Mt/y.

Copper is traditionally known as the "red" metal after its natural color. However, it is also known as a "green" metal for the green patina that it acquires due to weathering. Indeed, patinized copper is the architectural focal point of many modern buildings for its natural look.
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, which will ultimately be made into products for everyday use.The most common types of ore, copper oxide and copper sulfide, undergo two different processes, hydrometallurgy and pyrometallurgy, respectively, due to the different ...
