The Anaconda Copper Mining Company, part of the Amalgamated Copper Company from 1899 to 1915, was an American mining company. It was one of the largest trusts of the early 20th century and one of the largest mining companies in the world for much of the 20th century.. Founded in 1881 when Marcus Daly bought a silver mine, the company expanded rapidly based on the discovery of huge copper .
The main source of copper produced by KGHM are mines solely owned by the company. The exception is Sierra Gorda mine in Chile, which is now at the commissioning stage, where KGHM owns 55% of shares. The remaining mines are located in Poland (Lubin, Rudna, PolkowiceSieroszowice), Chile (Franke, Sierra Gorda), Canada (McCreedy, Morrison) and the USA (Carlota, Robinson).

Historically, mercury was used extensively in placer gold mining in order to form mercurygold amalgam with smaller gold particles, and thereby increase the gold recovery rates. Largescale use of mercury stopped in the 1960s. However, mercury is still used in artisanal and smallscale gold mining (ASGM), often clandestine, gold prospecting.
The development of more efficient processing techniques in the late1800s allowed the mining of lowergrade copper ores from huge openpit mines in the western United States. Today, the United States and Chile are the world''s top two copper producing countries, followed by Russia, Canada.

The barren rock, or gangue has to be separated from the sulfide minerals in order to smelt the metallic copper from the ore. By far the greatest proportion of copper is extracted from the sulfides of copper, iron and sometimes other metals. Such ores originate from sulfurbearing volcanic magmas, which have separated into metal sulfides and siliceous melts.
Patents for the electromining process have been issued in Chile, South Africa and China and are pending in the United States, Canada, Australia and Brazil. According to the company, this patented process is significantly faster, cheaper, and more environmentally friendly than traditional copper .
