20140326354Method and System for Solution Mining - A relatively warm mineral deposit is solution mined by injecting fluid through a well drilled into the deposit and dissolving the mineral to form a production brine. Warm production brine is cooled at the surface using a heat exchanger as a crystallizer to precipitate the mineral in the exchanger and form a slurry.
