Abstract
The present invention relates to an improved process for the solution mining of a mineral from a subterranean formation. More specifically, the invention relates to an improved process which enhances significantly the recovery of a mineral from a subterranean formation via solution mining. The improvement comprises periodically ceasing injection of leach solution while continuing production to alter the path of flow of the leach solution between an injection well and a production well and subsequently injecting leach solution.
