Bingham Canyon Mine
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 human-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 (17,000,000 long tons; 17,000,000 t). 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 (3.0 sq mi; 770 ha; 7.7 km2). 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.
Minerals, in the form of copper ore, were first discovered in Bingham Canyon in 1848 by two brothers, Sanford and Thomas Bingham, sons of Erastus Bingham, Latter-Day Saint pioneers of September 1847, who grazed their cattle there. They reported their find to their leader, Brigham Young, who advised against pursuing mining operations because the survival and establishment of settlements were of paramount importance at that time. The brothers applied to that purpose as directed and did not stake a claim. In 1850, the Bingham family went to settle what is now Weber County, leaving the canyon still today known by their name.
Bingham mine was part of the historical West Mountain Mining District. It was not until September 17, 1863, with the organization of mining districts in the state of Utah, that extraction of ore began, and the potential of the canyon's mineral resources began to be widely recognized. The first claim located was "Jordan S.M.Co" (Silver Mining Company) on September 17, 1863, the day the district was organized. Soon followed were other mining claims, including Galina and Independence in 1864, and Buckeye and Spanish in 1865. George B. Ogilvie and 23 others located the West Jordan claim in 1870. At first, mining was confined to placer gold, lead-silver, and copper-gold. Porphyry copper required processing and a railroad, which reached the canyon in 1873.
Enos Andrew Wall started working claims in 1887. His extensive tunnels and test pits, on his 200-acre (81 ha), indicated ore containing 2% copper.
The canyon's 19th Century mines were relatively small, and it wasn't until the end of the century that very large-scale exploitation of the canyon's ore bodies began to develop with open-pit mining. In 1896, Samuel Newhouse and Thomas Weir acquired the Highland Boy Mine, which was rich in copper, silver, and gold. Together they formed the Utah Consolidated Gold Mines, Ltd. with English investors. They then formed the Boston Consolidated Gold and Copper Co., Ltd., for the development of low-grade copper ore adjacent to the Utah Copper Company site.
Another significant development took place in 1903, when Daniel C. Jackling and Enos A. Wall organized the Utah Copper Company. Utah Copper immediately began construction of a pilot mill at Copperton, just beyond the mouth of the canyon, and the company actually started mining in 1906.
The success of Utah Copper in mining the huge but low-grade porphyry copper type ore body at Bingham Canyon was based on Jacklin's 1904 decision to use open-pit mining, steam shovels, and the railroad. The mine became a showplace for "railroad-pit operations," and the industrial complex defined by the mine and the ASARCO smelting operation made it the "largest industrial mining complex in the world" by 1912.
Utah Copper and Boston Consolidated merged after their separate surface operations approached each other in 1906. The Kennecott Copper Corporation, established to operate mines in Kennecott, Alaska, purchased a 25 percent financial interest in Utah Copper in 1915, which increased to 75 percent in 1923.
