ABSTRACT:
Lithium chloride is separated from its mixtures with calcium chloride by preferentially dissolving the lithium chloride in tetrahydrofuran. The separation is achieved since the lithium chloride is soluble in tetrahydrofuran, while the calcium chloride is not. The process is particularly applicable to geothermal brines.
