Abstract
A process for forming useful sodium salts by uniquely processing dilute brine solutions having sodium bicarbonate concentrations is disclosed. The dilute brine is reduced in sodium bicarbonate content to prevent precipitation of the sodium bicarbonate in subsequent crystallization of sodium carbonate decahydrate. The reduced brine is directed to a crystallizer operated to form pure sodium carbonate decahydrate crystals and a carbonate/bicarbonate containing mother liquor. The mother liquor is then recycled as a portion of said aqueous solvent to be used in the solution mining of the ore deposit.
