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). 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) usua在geoinfo.nmt.edu上查看更多信息

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.*...
