Uranium Mining and Milling (Technical Report) | OSTI.GOV

Uranium is a naturally occurring radioactive element used for fuel in nuclear power reactors. Canada is one of the world's largest uranium producers. The majority of Canada's production is exported. Uranium is mined to provide uranium ore which is processed at a milling facility to produce uranium concentrate.

Uranium Milling - Mineral Processing & Metallurgy

Uranium ore is simply rock with elevated amounts of uranium in it. Once the rock has been removed by open pit or underground mining it must be milled to separate the uranium from other constituents. The milling process for uranium is similar to that used for other metals such as copper, gold or nickel.
