ABSTRACT:
The present invention provides an improved process for the in-situ recovery of mineral values, particularly uranium, from subterranean deposits that exhibit heterogeneous permeabilities in the formation zones. Aqueous solutions of thickening agents or viscosity building agents are utilized to control the mobility of the leaching solutions as they traverse the subterranean formation to solubilize the mineral values therein.
