Abstract
The present invention is directed to a method for the production of lithium hydroxide (LiOH) directly from lithium chloride (LiCl), without the need for an intermediate production of lithium carbonate or similar. Specifically, the invention teaches a method for producing lithium hydroxide directly from lithium chloride, wherein LiCl is converted to LiOH from a brine, the LiOH is then crystallised to obtain crude lithium hydroxide monohydrate (crude LiOH·H2O) and then undergoes a second crystallization to produce pure LiOH·H2O. Finally, it is dried and packaged.
