Chile, the world's leading copper producer by far, produced an estimated 5.6 million metric tons of copper in 2019. In second place is Peru, with an estimated copper mine production of 2.4 million metric tons in the same year. The world's third-largest copper producer from mines is China. In 2019, China produced an estimated 1.6 million metric tons of copper from mines, which is over three times less than Chile's production.
