The World's 20 Largest Copper Mines 2014

A look at the twenty biggest copper miens

Copper production capacity at the world's 20 largest mines accounted for over 8.1 million metric tons in 2014. That is nearly 40 percent of the world's total copper mine capacity.  

About 75 percent of these mines produce concentrate while only about a quarter use a solvent-extraction electro-winning (SX-EW) process to produce electrolytic copper cathodes. 

Despite the high costs of production, copper mines still account for about 80 percent of total refined copper production annually. The remaining 20 percent comes from recycled scrap sources. 

Looking at the 20 largest mines, Latin America has a big presence. Mines here account for over 40 percent of mine capacity at the world's largest copper sources. In fact, eight of the mines are located in Chile alone.

Four of the top 20 mines are operated by the Chilean state-owned company, and world's largest producer of copper, Codelco. 

The high costs of financing a major mine are reflected in the fact that seven of the top ten mines are jointly owned by major mining corporations. 

The list below is compiled from information from the ICSG Directory of Copper Mines and Plants (2014). Beside each mine's name is the country that it is located in and its annual production capacity in thousands of metric tonnes - or kilotonnes (kt).

Managed by BHP Billiton, the Escondida copper mine in Chile's Atacama desert is jointly owned by BHP Billiton (57.5%), Rio Tinto Corp. (30%) and Japan Escondida (12.5%). In 2014, the massive Escondida mine accounted for five percent of total global copper mine production. Gold and silver are extracted as by-products from the ore.

Chile's second largest copper mine, Collahuasi, is a owned by a consortium of Anglo American (44%), Glencore plc (44%), and Mitsui + Nippon (12%). The operators of Collahuasi mine and produce copper concentrate and cathodes and molybdenum concentrate. Most of the concentrate produced at Collahuasi is sold to smelters in China for further refining.
