• Uranium: How is it Mined?

    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).

    As with other types of hard rock mining there are several methods of extraction. In 2012, the percentage of the mined uranium produced by each mining method was: in-situ leach (44.9 percent), underground mining (26.2 percent), open pit (19.9 percent), and heap leaching (1.7 percent). The remaining 7.3% was derived as a byproduct of mining for other minerals, and miscellaneous recovery. In open pit mining, overburdenis removed by drilling and blasting to expose the ore body, which is then

    Mining. In general, uranium mining is relatively similar to other kinds of mining unless the ore is very high grade. In this case, special mining techniques are used to limit worker radiation exposure and to ensure the safety of the environment and general public. Depending on the deposit, uranium is mined in one of three ways: open pit, underground, or in situ recovery.
