Extraction of lithium with chemical additives

A process for extracting lithium from a liquid resource, comprising:

• (a) contacting a chemical additive with said liquid resource, a wash solution used to contact an ion exchange material, an acidic solution, or any combination thereof;
• (b) contacting said ion exchange material to said liquid resource, wherein said ion exchange material absorbs lithium ions from said liquid resource to provide a lithiated ion exchange material;
• and
• (c) contacting said acidic solution to said lithiated ion exchange material, wherein said lithiated ion exchange material releases the absorbed lithium into the acidic solution to yield a lithium eluate,
• wherein dissolution of said ion exchange material into said liquid resource, said acidic solution, or said wash solution is reduced while (a), (b), and (c) are carried out as compared to when only (b) and (c) are carried out.
