ABSTRACT:
A solution mining process for recovering mineral values from a subterranean mineral-bearing formation, which includes (1) a first injection-and-production phase during which a leaching solution is injected into the formation and a pregnant liquor is simultaneously recovered from the formation, (2) a production-only phase during which injection is suspended and additional pregnant liquor is recovered from the formation, and (3) a second injection-and-production phase.
