Copper mining is the main export industry in Chile, and Chile is the main exporter of copper in the world. With a total annual production of two million tons, Chile accounts for 10 percent of the world's production of copper. Several major international mining firms produce copper in Chile, including Billiton, Rio Tinto and Anglo American. The largest copper mining company in the world is CODELCO (National Copper Corporation of Chile), which, while state-owned, is run independently as a corporation.
