    Uranium mining is the process of extraction of uranium ore from the ground. The worldwide production of uranium in 2015 amounted to 60,496 tonnes. Kazakhstan, Canada, and Australia are the top three producers and together account for 70% of world uranium production. Other important uranium producing countries in excess of 1,000 tons per year are Niger, Russia, Namibia, Uzbekistan, China, the United States and Ukraine.

Uranium from mining is used almost entirely as fuel for nuclear power plants. Uranium ores are normally processed by grinding the ore materials to a uniform particle size and then treating the ore to extract the uranium by chemical leaching. The milling process commonly yields dry powder-form material consisting of natural uranium, "yellowcake," which is sold on the uranium market as U3O8.

    While uranium is used primarily for nuclear power, uranium mining had its roots in the production of radium-bearing ore from 1898 from the mining of uranium-vanadium sandstone deposits in western Colorado. The 1950s saw a boom in uranium mining in the western U.S., spurred by the fortunes made by prospectors such as Charlie Steen. The United States was the world's leading producer of uranium from 1953 until 1980. In 1960 annual U.S. production peaked at 17,055 metric tons U3O8. Until the early 1980s, there were active uranium mines in Arizona, Colorado,

    While uranium is used primarily for nuclear power, uranium mining had its roots in the production of radium-bearing ore from 1898 from the mining of uranium-vanadium sandstone deposits in western Colorado. The 1950s saw a boom in uranium mining in the western U.S., spurred by the fortunes made by prospectors such as Charlie Steen. The United States was the world's leading producer of uranium from 1953 until 1980. In 1960 annual U.S. production peaked at 17,055 metric tons U3O8. Until the early 1980s, there were active uranium mines in Arizona, Colorado, New Mexico, Oregon, South Dakota, Texas, Utah, Washington and Wyoming. Price declines in the late 1970s and early 1980s forced the closure of numerous mines. 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 late 1970s. By 2001, there were only three operating uranium mines (all in-situ leaching operations) in the United States. Annual production reached a low of 779 metric tons of uranium oxide in 2003, but then more than doubled in three years to 1672 metric tons in 2006, from 10 mines. The 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 (U3O8) increased from $7.92 per pound in 2001 to $39.48 per pound ($87.04/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 reserv

    Different Kinds of MinesMilling and ProcessingTailings Management and Mine RehabilitationThe Health of WorkersSustainable Development Reporting and AuditUranium Resources and SupplyEconomics of Uranium MiningIssues Related to Uranium MiningSome Uranium BasicsWhere orebodies lie close to the surface, they are usually accessed by open cut mining, involving a large pit and the removal of much overburden (overlying rock) as well as a lot of waste rock. Where orebodies are deeper, underground mining is usually employed, involving construction of access shafts and tunnels but with less waste rock removed and less environmental impact. In either case, grade control is usually achieved by measuring radioactivity as a surrogate for uranium concentration.*.
