title: Uranium mining in the United States text: 1954 in the Sierra Nevada of Kern County, along the Kern River about northeast of Bakersfield. Two mines, the Kergon mine and the Miracle mine, made small shipments in 1954 and 1955. Uranium occurs as uraninite and autunite in shear zones in granodiorite. Accessory minerals include fluorite and the molybdenum minerals ilsemanite and jordisite. The first uranium identified in the US was pitchblende from the Wood gold mine at Central City, Colorado in 1871. Uranium mining in southwest Colorado goes back to 1898. The Uravan district of Colorado and Utah supplied about half the world's radium from 1910 to 1922, title: Uranium mining in the United States text: Uranium mining in the United States Uranium mining in the United States produced of UO (1271 tonnes of uranium) in 2015, 32% lower than 2014's production of of UO (1881 tonnes of uranium) and the lowest US annual production since 2005. The 2015 production represents 7% of the anticipated uranium market requirements of the US's nuclear power reactors for the year. Production came from one conventional uranium mill in Utah, and six in-situ leach operations: four in Wyoming, one in Texas and one in Nebraska. While uranium is used primarily for nuclear power, uranium mining had its roots in the title: Uranium mining in the United States text: mining to be pursued. It also was not asked to compare the relative risks of uranium mining to the mining of other fuels such as coal. In October 2015, it went before a federal judge whether the 33-year-old ban on large-scale uranium mining in Virginia would be lifted. Uranium was discovered at the Midnite Mine deposit on the Spokane Indian Reservation, Stevens County, north-east Washington in 1954. The deposit was mined from an open pit 1956–1962 and 1969–1982. Production through 1975 was 8 million pounds (3,600 metric tons) of UO. The uranium is contained in autunite, uraninite, and coffinite, with title: Uranium mining in the United States text: U.S. DOE's Energy Information Administration reported that 90% of U.S. uranium production in 2006 came from in-situ leaching. The average spot price of uranium oxide (UO) increased from $7.92 per pound in 2001 to $39.48 per pound ($/kg) in 2006. In 2011 the United States mined 9% of the uranium consumed by its nuclear power plants. The remainder was imported, principally from Russia and Kazakhstan (38%), Canada, and Australia. Although uranium production has declined to low levels, the United States has the fourth-largest uranium resource in the world, behind Australia, Canada, and Kazakhstan. United States uranium reserves are strongly dependent title: Uranium mining by country text: and 2005. Most uranium ore in the United States comes from deposits in sandstone, which tend to be of lower grade than those of Australia and Canada. Because of the lower grade, many uranium deposits in the United States became uneconomic when the price of uranium declined sharply in the 1980s. Today nearly all uranium operations in the United States are In-situ leach. Regular production of uranium-bearing ore in the United States began in 1898 with the mining of carnotite-bearing sandstones of the Colorado Plateau in Colorado and Utah, for their vanadium content.
