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.

Embodiments of the present disclosure are directed to methods for recycling waste ion exchange materials comprising a first alkali metal salt and a second alkali metal salt comprising reducing the size of the waste ion exchange materials to produce a plurality of waste ion exchange particles having particle sizes from 0.10 mm to 5.0 mm, and regenerating the plurality of waste ion exchange particles to produce a plurality of regenerated ion exchange particles having a concentration of the first alkali metal salt greater than a concentration of the first alkali metal salt in the waste ion exchange materials. Systems for recycling a waste ion exchange materials comprising a first alkali metal salt and a second alkali metal salt are also disclosed.

This invention relates to a method for preparing a lithium activated alumina intercalate solid by contacting a three-dimensional activated alumina with a lithium salt under conditions sufficient to infuse lithium salts into activated alumina for the selective extraction and recovery of lithium from lithium containing solutions, including brines.
