Uranium has been mined since about 1830 as a glass and glaze colorant, but its exploitation began in earnest in the 1940s, initially for military purposes but then from the mid1950s for fuel for nuclear power plants. Mining from underground and open cut mines has dominated production. Ore grades have ranged from over 15% to

  • Uranium Recovery NRC.gov

    2023331· Uranium recovery is the first step removing uranium from the Earth and milling it to produce a product called “ yellowcake ” that becomes the basis of nuclear fuel. Uranium recovery is typically accomplished in two ways:Exploration, Mining, Milling and Processing of Uranium,2023516· The average concentration of uranium in the earth’s crust is about 2.76 ppm in rocks [ 2 ], less than 1 ppb in surface water, 0.5–10 ppb in ground water, and 3 ppb in sea water. About 1.3 × 10 14 tons of uranium exists in the earth’s crust. However, presently, rocks are the only source from which extraction of uranium is viable.
