ABSTRACT:
An anion exchange resin, containing Al(OH).sub.3 suspended therein, is reacted with aq. LiOH to form microcrystalline LiOH.2Al(OH).sub.3 which is then reacted with a halogen acid or halide salt to form microcrystalline LiX.2Al(OH).sub.3. The resin, after having a portion of the LiX eluted by using an aqueous wash, is used to recover Li.sup.+ values from aqueous brines.
