Brine mining is the extraction of useful materials (chemical elements or compounds) which are naturally dissolved in brine.The brine may be seawater, other surface water, groundwater, or hyper-saline solutions from several industries (e.g., textile industries). [1] It differs from solution mining or in-situ leaching in that those methods inject water or chemicals to dissolve materials …
