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 from over 15% to …
