    摘要: 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.

    摘要: Morphologically altered pellets of a polycrystalline hydrated alumina, intercalated with LiX (where LiX is a lithium salt, preferably LiCl), is prepared by contacting the polycrystalline structure with LiX solution carried in NaCl brine, the LiX creating lithium-specific sites of intercalation in the crystalline structure, and the material is used in a LiX absorption process involving unloading LiX from the pellets, and then passing a LiX-containing brine through the pellets to capture more LiX in the Li-depleted active sites, and repeating the unloading and loading of the LiX a plurality of cycles. The unloaded LiX is collected as crude product which can be concentrated by evaporation and removing precipitated NaCl.
