Brine mining - Wikipedia

Brine mining is the extraction of useful materials (elements or compounds) which are naturally dissolved in brine.The brine may be seawater, other surface water, or groundwater.It differs from solution mining or in-situ leaching in that those methods inject water or chemicals to dissolve materials which are in a solid state; in brine mining, the materials are already dissolved.
