  • Rock Salt: A sedimentary rock composed of the mineral halite

    Solution mining of salt is done by injecting hot water under pressure down a well into a subsurface layer of rock salt. That same water is then withdrawn up to the surface through a nearby recovery well. While the water travels through the layer of rock salt from the injection well to the recovery well it dissolves a significant amount of salt.
