Uranium mining - Wikipedia

OverviewHistoryDeposit typesExplorationTechniquesUranium pricesUranium 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.

Open Pit MiningUnderground MiningMillingIn-Situ RecoverLinks to More InformationOpen pit mining, also known as strip mining, is the removal of surficial soils and uneconomic rock to get at the ore below. Ore grades are normally less than 0.5%. This is type of mining is only possible if the uranium ore is near the surface (normally less than 400 ft). The Jackpile Mine on Laguna Pueblo was once the world's largest open pit uranium mine.Waste rock or overburden (the material removed over the ore body) usually is stored near the open pit. Once the ore horizon is exposed, a s...

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.*...
