Yellowcakes (aka, (also known as) urania) are uranium concentrates obtained from leach solutions. They represent an intermediate step in the processing of uranium ores. Yellowcake concentrates are prepared by various extraction and refining methods, depending on the types of ores. Typically yellowcakes are obtained through the milling

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
