  • Uranium mining (open cut and underground) and milling Uranium .

    Abstract. 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 mid 1950s for fuel for nuclear power plants. Mining from underground and open cut mines has dominated production. Ore grades have ranged.
