Abstract: The present invention relates to a system for production of lithium hydroxide, comprising: a) an ion exchange unit containing ion exchange particles that absorb lithium from a liquid resource and that then release the absorbed lithium into an eluent comprising nitric acid to yield an eluate comprising lithium nitrate; b) a heating unit that decomposes said lithium nitrate to crystallize lithium oxide solids while releasing nitrogen oxide gas; c) an absorption unit that absorbs said nitrogen oxide gas into a scrubbing solution to yield recycled nitric acid; and d) a hydration unit that combines said lithium oxide solids with water to form lithium hydroxide.
