Uranium Mining Processing and ReclamationUranium

A hydrometallurgical process is used to produce uranium from uranium ore using chemicals and solutions to extract the uranium from the ore matrix. The process is complete when the final uranium product known as yellowcake is produced in a sufficient high purity typically 75 to 85 percent U 3 O 8 so that it can be used in the remainder of
