Uranium Mining and Extraction from Ore - Stanford

2016-8-3  Uranium Extraction. Uranium leaching is the process by which the uranium is extracted from the raw ore by reacting the material with acid or base. Fig. 2 shows a general process flow for the uranium extraction process. Prior to the leaching process, the ore is often given preliminary treatments that can include roasting and grinding.

2014-6-30  Either natural uranium or uranium enriched in 235 U isotope is used as fuel in nuclear reactors. Before it becomes fuel for power plants, uranium ore has to go through several processing steps. These include crushing, grinding, leaching, concentration and purification by solvent extraction and ion exchange, to take the form of a pure U 3 O 8 oxide.
