Abstract
The present disclosure is directed to a new and improved separation individual minerals from brines containing a mixture of minerals. The brines may be derived from seawater, brackish water, oilfield brines, solution mining, mine run-off, and other sources. Typically, the minerals are recovered as chlorides using a variety of processing steps including evaporation, centrifugation, elutriation, filtration, electrocogulation, crystallization, adsorption, and chromatography.
