Uranium mining is the process of extraction of uranium ore from the ground. The worldwide production of uranium in 2019 amounted to 53,656 tonnes. Kazakhstan, Canada, and Australia were the top three uranium producers, respectively, and together account for 68% of world production. Other countries producing more than 1,000 tonnes per year included Namibia, …

Mining and milling residues are the solid and liquid wastes left over from the mining and milling of ores to recover uranium [3]. The major solid residues are ura-nium mill tailings; mining debris, including barren rock and low grade ore; residues from heap leaching; and scrap material and equipment from maintenance and decom-missioning [4].

• Residues of these past six decades of mine and mill processing of uranium ore in Europe have resulted in a considerable legacy. • Although this legacy is much smaller in volume than that resulting from other types of metal or coal mining, the enhanced radioactivity associated with uranium mining requires specific attention.

Uranium is the fuel used in nuclear reactors and is also a material for nuclear bombs, such as the bomb that was dropped on Hiroshima in 1945. Uranium ore from mining has to be processed in order to concentrate the levels of the component U-235 to the 3-5% required for nuclear reactor fuel, or to the 90% or more required for weapons-grade material.

Uranium is a naturally occurring radioactive element used for fuel in nuclear power reactors. Canada, one of the world's largest uranium producers, accounts for 18 percent of global production and exports 90 percent of its uranium. Uranium is mined so it can be processed at a milling facility in order to recover the uranium concentrate.

Milling: This process takes place at a mill after the ore containing uranium is removed from the Earth through open pit or underground mining. The ore is brought to a mill, crushed, and ground up before chemicals are added to dissolve the uranium. The uranium is then separated from the chemical solution, solidified, dried and packaged.
