the world's 20 largest copper mines

The world's 20 largest copper mines produce nearly 9 million metric tons of the precious metal a year, about 40% of the world's total copper mine capacity. Chile and Peru, alone, account for more than half of the copper mines on this list. The U.S. makes the cut, as well, with two mines among the top 20.

Copper is expensive to mine and refine.The high costs of financing a major mine are reflected in the fact that many of the mines with the most production capacity are either state-owned or owned by major mining corporations like BHP and Freeport-McMoRan.

The list below is compiled from theInternational Copper Study Group'sWorld Copper Factbook 2019. Beside each mine's name is the country that it is located in and its annual production capacity in metric kilotons. Ametric ton is equal to about 2,200 pounds. A metric kiloton (kt) is 1,000 metric tons.

The Escondida copper mine in Chile's Atacama desert is jointly owned by BHP (57.5%), Rio Tinto Corp. (30%), and Japan Escondida (12.5%). In 2012, the massive Escondida mine accounted for 5% of total global copper mine production. Gold and silver are extracted as by-products from the ore.

Copper is an essential part of peoples lives. Today, copper is the material of choice for powering our modern world as a vital component in everything from power generation and hybrid vehicles to computers and smartphones.

Energy is essential to our lives. We all rely on energyto keep the lights on, to get to work, or to heat or cool our homes. As populations around the globe particularly in developing nations grow and become increasingly urbanized, the demand for energy is increasing.

Zinc protects steel by improving its durability. The primary uses of zinc are for galvanizing steel to protect against weather and corrosion, producing brass and bronze, and in die-casting to produce a wide range of metal products. When added to fertilizers, zinc can increase crop yields and crop quality. And, as an essential nutrient in human development and disease prevention, zinc saves lives.

Steelmaking coal is an essential ingredient in the production of steel. Also called metallurgical or coking coal, it is a necessary ingredient in producing steel for building infrastructure such as rail, bridges and schools improving the quality of life for people around the world. Steel and steelmaking coal are required for everything from clean energy projects like wind or solar power to transportation like rapid transit, buses and vehicles.
