NRC: Uranium Recovery

As the precursor to the nuclear fuel cycle, uranium recovery focuses on extracting (or mining) natural uranium ore from the Earth and concentrating (or milling) that ore. These recovery operations produce a product, called " yellowcake ," which is then transported to a fuel cycle facility .
