text: A method of mining potassium chloride from a subterranean sodium chloride containing deposit which contains at least percent by weight potassium chloride which comprises bringing a plurality of cased bore holes thermally isolated from each other into communication with a cavity in the deposit, feeding solvent at less than 100 C. through at least one of the cased holes to the cavity, dissolving potassium chloride and sodium chloride from the deposit to form an aqueous solution richer in both potassium chloride and sodium chloride than the solvent and withdrawing enriched solution through at least one of the remaining cased holes while maintaining the temperature of the solvent hotter than the effluent and maintaining the temperature of the effluent Within about 15 C. of the natural formation temperature thereby avoiding undue cooling of the cavity solution.
