ABSTRACT:
The present invention relates to an improved method for the solution mining of a mineral from a subterranean formation. More specifically, the invention relates to an improved method which enhances significantly the recovery of a mineral via solution mining with an injection and production well from a subterranean formation which contains the mineral in a zone of low permeability having a zone of higher permeability both above and below it. The improvement comprises locating an injection well in one zone of high permeability and a production well in the other zone of high permeability.
