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