Abstract
1,227,822. Solution mining. INTERNATIONAL SALT CO. 2 July, 1968, No. 31618/68. Heading E1F. A method of solution mining of a subterranean deposit of a soluble mineral involves pumping a saturated solvent down to the deposit and allowing the solvent as it descends to absorb heat from the surrounding strata, which is at a substantially higher temperature, so that the solvent is no longer saturated when it reaches the deposit. The solvent is thus able to dissolve and absorbed some of the deposit as it passes through the deposit before being returned, whilst being maintained at substantially the same temperature and pressure as exists in the deposit, through an uptake for discharge into recovery apparatus, where a reduction of temperature and pressure of the solvent, allows separation from the solvent of the now excess mineral therein. Before the solvent is recycled to the deposit. Heat loss from the uptake is minimised by insulation or by passing hot solvent vapours from the recovery apparatus down and up through casing coaxial with the casing of the uptake before exhaust of the vapours to the atmosphere. U.S.A. Specifications 2,555,340, 2,876,182, 3,064,957 and 3,174,549 are referred to.
