Abstract:
A process ( 10 ) for the treatment of a lithium containing material, the process comprising the steps of: (i) Preparing a process solution from the lithium containing material ( 12 ); (ii) Passing the process solution from step (i) to a series of impurity removal steps ( 36 ) thereby providing a substantially purified lithium chloride solution; and (iii) Passing the purified lithium chloride solution of step (ii) to an electrolysis step ( 70 ) thereby producing a lithium hydroxide solution.

Claim (Index 3):
The process of  claim 1 , wherein the impurity removal steps of step (ii) include one or more of hydropyrolysis of Al and Fe chlorides, pH increase to precipitate hydroxides of Al, Fe, Mg and Mn, lithium carbonate precipitation for removal of Ca, and fractional crystallisation for removal of Na and K.
