Claim 0:
1. A process for manufacturing a lithium selective adsorbent, the process comprising the steps of:
a. intercalating an initial quantity of Gibbsite-bearing adsorbent precursor with lithium under alkaline conditions at a predetermined intercalation temperature using a pre-intercalation reaction volume of an intercalation reaction liquor to produce an intercalated layered aluminate adsorbent and a post-intercalation reaction volume of a partially depleted intercalation reaction liquor, wherein the intercalation reaction liquor comprises a lithium salt and an alkali in a brine, wherein the intercalation temperature is between about 25° C. and about 125° C., wherein the lithium salt comprises LiCl, wherein the alkaline conditions comprises an alkaline pH from about 7 to about 13, and wherein an alkali comprises NaOH;
b. decanting the post-reaction volume of the depleted intercalation reaction liquor from the intercalated layered aluminate adsorbent;
c. neutralizing the intercalated layered aluminate adsorbent under acidic conditions using an acid at a predetermined neutralization temperature to form the lithium selective adsorbent, wherein the neutralization temperature is between about 25° C. and about 115° C., and wherein an acid is acetic acid;
d. augmenting the decanted intercalation reaction liquor from step b. by adding brine, LiCl, and NaOH to reconstitute the pre-intercalation reaction volume of the intercalation reaction liquor from step a.; and
e. recycling the augmented intercalation reaction liquor from step d. in preparation for intercalating a subsequent quantity of Gibbsite-bearing adsorbent precursor according to step a.
