The Bingham Canyon Mine, more commonly known as Kennecott Copper Mine among locals, is an open-pit mining operation extracting a large porphyry copper deposit southwest of Salt Lake City, Utah, in the Oquirrh Mountains. The mine is the largest man-made excavation, and deepest open-pit mine in the world, which is considered to have produced more copper than any other mine in history – more than 19,000,000 short tons. The mine is owned by Rio Tinto Group, a British-Australian multinational corporation. The copper operations at Bingham Canyon Mine are managed through Kennecott Utah Copper Corporation which operates the mine, a concentrator plant, a smelter, and a refinery. The mine has been in production since 1906, and has resulted in the creation of a pit over 0.75 miles (1,210 m) deep, 2.5 miles (4 km) wide, and covering 1,900 acres. It was designated a National Historic Landmark in 1966 under the name Bingham Canyon Open Pit Copper Mine. The mine experienced a massive landslide in April 2013 and a smaller slide in September 2013.
