  • Process for recovering lithium from brine by salting out lithium sulfate monohydrate
    Patent number: 4287163
    Abstract: A salting-out process for recovering lithium from brines which have been concentrated by solar or thermal evaporation. Soluble sulfate salts are added to the strong brine solutions containing lithium to yield lithium sulfate monohydrate. Subsequent treatment of some residual brines with a strong acid will crystallize quantities of boron present as boric acid. Depending on the time of year and type of brine being used, a brine solar heating or plant evaporation system is provided to enhance the recovery processes.
