Mining operations at Ranger commenced in 1980 with full production starting in October 1981, producing uranium oxide concentrate (U3O8) at a rate of around 3,300 tons per year (World Nuclear Association, 2022). Because the Ranger uranium ore body lies close to the surface, open pit, or open cut, mining is used for access.

Uranium processing - Leaching, Extraction, Purification: Roasted uranium ores are leached of their uranium values by both acidic and alkaline aqueous solutions. For the successful operation of all leaching systems, uranium must either be initially present in the more stable hexavalent state or be oxidized to that state in the leaching process. Acid leaching is commonly performed …
