  • Uranium: How is it Mined?

    Open 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 uraniuUnderground MiningMillingIn-Situ RecoverLinks to More InformationUnderground mining is used to get at higher concentrations of uranium that are too deep to get at from open-pit. The ore is drilled, then blasted to create debris which is then transported to the surface, then on to a mill.

    Open-pit mining and underground mining are the two types of mining that would be used to exploit uranium deposits in Virginia. These mining techniques can be used individually or combined; for example, many mines start as open-pit operations and continue as underground operations to follow a deposit deeper below the surface.

  • Uranium mining - Energy Education

    Open PitUndergroundin Situ RecoveryWhen uranium is found near the surface - usually no more than 100 meters deep - it can be extracted via open pit mining. In this method, soil and waste rock is removed by heavy equipment, allowing the ore to be accessed. The mines are carved out into sections called benches so that they can be mined methodically and safely.Holes are drilled into the benches and loaded with explosives; they detonate, breaking up the rocSee more on energyeducation.ca

  • Uranium Mining Overview - World Nuclear Association

    Mill chemistry. The crushed and ground ore, or the underground ore in the case of ISL mining, is leached with sulfuric acid: UO 3 + 2H + ====> UO 2 2+ + H 2 O UO 2 2+ + 3SO 4 2-====> UO 2 (SO 4) 3 4-. The UO 2 is oxidised to UO 3.. With some ores, carbonate leaching is used to form a soluble uranyl tricarbonate ion: UO 2 (CO 3) 3 4-.This can then be precipitated with an alkali, e.g. as sodium ...

  • Uranium mining - Energy Education

    Depending on the deposit, uranium is mined in one of three ways: open pit, underground, or in situ recovery. Open pit. When uranium is found near the surface - usually no more than 100 meters deep - it can be extracted via open pit mining. In this method, soil and waste rock is removed by heavy equipment, allowing the ore to be accessed.
