      Uranium mining is the process of extraction of uranium ore from the ground. The worldwide production of uranium in amounted to 60, tonnes. Kazakhstan, Canada, and Australia are the top three producers and together account for 70% of world uranium production. Other important uranium producing countries in excess of 1, tons per year are Niger, Russia, Namibia, Uzbekistan, China, . tersrand, South Africa, or Blind River/Elliott Lake district, Canada. Such uranium placers only formed in the Arche-an oxygen-free environment. Under recent atmospheric conditions, uraninite dissolves easily in rain water, and the erosion of uranium deposits, or even uranium-rich granites.

A Cameco plant at Blind River, Ontario refines uranium oxide concentrate, yellowcake, to produce UO3 which is then processed at Port Hope, Ontario. The yellowcake comes from Canadian and foreign mines.

The Port Hope plant converts about 80 percent of the Blind River output to UF6 which is then exported for enrichment elsewhere.
