  • Uranium mining - Canadian Nuclear Association

    When uranium ore is found near the surface, generally less than 100 metres deep, it is typically extracted by the open-pit mining method. Open-pit mining begins by removing soil and waste rock on top of the ore, to expose the hard rock. Then a pit is excavated to access the ore.
