Process for leaching base elements, such as uranium ore, in situ
Patent
·
OSTI ID:6973339
A process is described for leaching base elements, such as uranium values, from an underground water saturated ore deposit containing oxidizable materials such as sulfides, carbon, and the like. An oxygen-bearing gas is introduced into the ore deposit prior to or simultaneously with a leach solution to oxidize the base elements within the ore deposit to a soluble state where they can then be dissolved in the leach solution. Thereafter, the pregnant solution is withdrawn and treated by conventional techniques to remove the base elements. (21 claims)
