ABSTRACT:
A resin/aluminate composite which has been substantially loaded with Li.sup.+ values by being contacted with a contaminated, Li.sup.+ -containing aqueous solution, is pre-washed with a substantially pure, concentrated NaCl brine to remove the contaminants without removing the Li.sup.+ values, then is washed with water to leach out much, but not all, of the Li.sup.+ values. The resin/aluminate composite comprises a macroporous anion exchange resin having crystalline LiX.2Al(OH).sub.3 dispersed therein, where X is halide.
