Methods for making brines

摘要

Methods for making brines may generally comprise forming a mixture comprising: (i) a solid material produced as a by-product of the Kroll process including solid anhydrous magnesium chloride and solid elemental magnesium; (ii) an amount of a previously-produced brine; and (iii) an amount of water sufficient to provide a predetermined brine concentration. At least a portion of the solid material in the mixture is dissolved while simultaneously controlling the temperature of the mixture. At least a portion of insoluble matter is separated from the mixture.
