  • 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.

  • Pond sealing
    Patent number: 4222685
    Abstract: A method of providing a substantially impermeable lining to the bottom of an earthen pond using native soil. Such soil is classified and formed into a slurry containing fine particles of predominately five or less micron size. The pond bottom is covered with a first layer of the slurry which is allowed to dry to a point where large crack patterns develop. The cracks are filled with a second layer of the slurry. More layers may be applied to form a final lining having the desired permeability for the particular application.
