In Chile, which currently produces onethird of the world''s copper, many of the most copperrich ores have already been mined. As a result, biomining is increasingly being used to mine deposits with low percentages of copper, [2] and worldwide, 1015% of copper is extracted using bioleaching.
Mining copper About 200 years ago the UK was an important world source of copper and tin and there were mines in Cornwall and Devon. These mines have now closed and today the biggest copper mines are in Chile (ndida mine) and Indonesia (Grasberg mine). These produce many millions of tonnes of copper ore per year.

The Amalgamated Copper Co. took over Daly''s Anaconda Copper Mining Co., as well as Heinze''s holdings, and eventually all but some of Clark''s holdings until after he died in 1925. After the "war", Amalgamated was reminted into a new Anaconda Copper Mining Company.
Process steps include mining, concentration, roasting, smelting, converting, and finally fire and electrolytic refining. Process Description24 Mining produces ores with less than 1 percent copper. Concentration is accomplished at the mine sites by crushing, grinding, and flotation purification, resulting in ore with 15 to 35 percent copper.

The concentrated copper solution is dissolved in sulfuric acid and sent to the electrolytic cells for recovery as copper plates (cathodes). From the copper cathodes, it is manufactured into wire, appliances, etc. that are used in every day life. Below are some photos of the process equipment at an Arizona Copper Mine.
Copper is found alongside many other types of ore. It can be found near gold, silver, zinc, lead, and other types of metal deposits. When mixed in with other ores, copper is not usually found in great abundance. Until the development of the modern copper mining process, it was typically a byproduct of mining .
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.
