ABSTRACT:
Pellets of a polycrystalline hydrated alumina, especially Gibbsite, are infused with LiOH to obtain loadings up to 0.33 mol fraction of LiOH in the LiOH/Al(OH).sub.3. The so-prepared material is useful for mixing with a LiX-containing brine solution, producing an interaction of the LiOH infused in the alumina pellets with the X ion (where X represents an acid salt moiety, especially halide) of the LiX-containing brine. The LiX interaction product is efficiently removed from the alumina pellets by water washing, leaving rejuvenated LiOH which can be used in yet another cycling of LiX formation/water removal. A plurality of loading and unloading cycles are achieved, yielding an appreciable amount of the lithium values derived from the brine.
