Abstract: A method of producing lithium phosphate from a lithium source includes the step of (a) concentrating the lithium to produce a lithium concentrate, with an ion exchange sorbent, and (b) reacting the lithium concentrate with phosphate anions to produce lithium phosphate. The lithium phosphate may then be converted to lithium hydroxide or lithium 5 carbonate by reaction with calcium hydroxide or by electrolysis.
