ISR Mining - Uranium One
ISR mining technology was developed independently in both the Soviet Union and the United States in the mid-1960's. The method was developed to extract uranium from typical roll‐front type deposits (a sub‐type of sandstone uranium deposits) located in water‐saturated permeable sediments that were not suitable for economical conventional mining techniques.

Uranium processing - Leaching | Britannica
Uranium processing - Uranium processing - Leaching: 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 by agitating an …

Uranium - DuPont
Current mining practices using lower concentration leaching solutions generate large volumes of pregnant leach solutions (PLS), which favors the use of ion exchange (IX) for the recovery-purification step because IX can more economically concentrate uranium from large volumes of PLS. Many different engineered IX systems are used in uranium mining.
