Abstract

This invention relates to a method for preparing a lithium aluminate intercalate (LAI) matrix solid and methods for the selective extraction and recovery of lithium from lithium containing solutions, including brines. The method for preparing the LAI matrix solid includes reacting aluminum hydroxide and a lithium salt for form the lithium aluminate intercalate, which can then be mixed with up to about 20% by weight of a polymer to form the LAI matrix.
