Understanding sulphuric acid leaching of uranium from

Column leaching test was carried out for uranium ore samples obtained from a uranium insitu leaching (ISL) mining site using 2.45 bed volumes (BVs) of 0.255 M sulphuric acid to study the evolution of uranium concentration and its isotopic 234 U/ 238 U activity ratio in the pregnant leach solution. The activity ratio of the two uranium isotopes

Uranium processing Leaching Britannica

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 oreleach mixture

Uranium Ore Processing Key Considerations Based on
