Explanation: Leaching It is the process of removal of alkali salts dissolved in irrigation water by flooding the land with an adequate amount of water; Leaching is the process of a solute becoming extracted from its carrier substance by way of a solvent If carbon dioxide (CO 2) is present in water then it enhances the leaching process; ThisRoasted 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 for 4 to as long as 48uranium processing Leaching | Britannica
