Where Does Uranium Come From? Nuclear Energy Institute

Key Facts. Before its use in a nuclear reactor, a series of processing steps converts mined uranium ore into ceramic pellets, which are loaded into fuel rods.; Ore mined from open pit and underground mines travels to a conventional mill. Solvents or ion exchange processing removes the uranium, resulting in uranium oxide, or yellowcake, which is then filtered, dried and packaged.
