Uranium Mining and Milling
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.

The future of uranium mining in Australia
The mine is expected to produce 404.7 tonnes (t) of uranium in 2024 and see rising output levels, peaking at an estimated 854.4t of production in 2027, before levels steadily fall until 2030. At peak output, it is expected to contribute 1.1% of the global uranium supply.

Uranium. mining and processing. Uranium is extracted from ores whose uranium content is often less than 0.1 percent (one part per thousand). Most ore deposits occur at or near the surface; whether they are mined through open-pit or underground techniques depends on the depth of the deposit and its slope. The mined ore is crushed and the uranium ...
