摘要

A method of exploiting and concomitantly benefiting a deposit of soluble, high temperature, underground, deep mineral that includes impurities, disposed at such depth below the surface of the earth as to be surrounded by a geological environment of high temperature compared to the temperature of the rock from the surface of the earth in the vicinity to obtain a relatively pure mineral product at relatively low temperatures of the earth's surface environment, said method comprising forming a pair of openings extending downwardly in ratio of laterally displaced from the surface of the earth into said reservoir, pumping a dissolving liquid down through one of said openings in direct heat exchange relationship with the geological environment, whereby said solvent is heated to a high temperature, and then direct said heated solvent to pass in dissolving contact ratio through said mineral at high temperature to produce a highly concentrated, high temperature mineral solution, and then flowing up through the other of said openings to a treatment plant operating substantially under conditions of temperature and pressure of the surface of the earth, for the separation of the purified mineral from the impurities of said solution while simultaneously being circulated, in heat exchange relation with the mentioned ascending mineral solution a heat exchanger fluid which it flows in a closed duct system including a heater whereby mixing with said solution is prevented and said solution is maintained in a prescribed high temperature condition until supply to said treatment plant.
