Copper extraction refers to the methods used to obtain copper from its 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.
The largest copper mine in North America and the world39s largest manmade 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 America39s lowestcost copper producer , a model of operational efficiency and environmental compliance.
The Basics of Copper Mining and Processing. Mined from open pits, copper ore must be crushed as part of the process that occurs between extraction and production. Using todays compact mining equipment, copper ore is extracted from the mine. After the ore is crushed, its roasted, which helps to convert sulfides to oxides.
Copper got its name from the word Cuprum, which is the Latin name of Cyprus, the largest site of copper mining during the time of Roman Empire. The symbol Cu is also derived from there. Until 1982, US penny was made from 95 copper and 5 zinc. However, now the composition is 97.5 zinc and 2.5 copper.
