A process for recovery of lithium ions from a lithium-bearing brine includes contacting the lithium-bearing brine with a lithium ion sieve (where that LIS includes an oxide of titanium or niobium) in a first stirred reactor to form a lithium ion complex with the lithium ion sieve, and decomplexing the lithium ion from the lithium ion sieve in a second stirred reactor to form the lithium ion sieve and an acidic lithium salt eluate.

The present invention relates to the extraction of lithium from liquid resources such as natural and synthetic brines, leachate solutions from minerals, and recycled products.

Proposed is an inorganic ion-exchanger, which is selective to lithium and constituted a non-stoichiometric compound in the form of solid particles of a polymeric aqua-oxo-hydroxo complex represented by the following general formula: H.sub.aNbO.sub.(2.5+0.5.Math.a).cZrO.sub.2.dH.sub.2O, wherein: a is a number ranging from 0.5 to 1.5, c is a number ranging from 0.01 to 1.0, and d is a number ranging from 0.1 to 2.0. The complex has a total ion exchange capacity of at least 3.5 meq/g and an ion-exchange capacity specifically to lithium of at least 2.5 meq/g. This ion-exchanger is intended for selective extraction of lithium from lithium-containing natural and industrial brines.
