<p>Solution mining method for recovery of soluble salts from inclined strata, particularly those at substantial depths, and involving the dissolution of ore strata, overlain by insoluble strata, while leaving the remainder of the formation in place. Water is injected down a bore hole at a predetermined rate and, being much less dense than brine, flows in a updip direction along the top of the cavity to a forward mining face remote from the drill hole. Loaded, heavy brine flows downdip along the bottom of the stratum to an outflow pile communicating with the bottom of the bore hole.</p> |
