<p>A process for the treatment of lithium containing ore, the process comprising the steps of: (i) Calcining an alpha-spodumene ore or ore concentrate to produce betaspodumene; (ii) Passing the beta-spodumene of step (i) to a leach step in which the beta-spodumene is leached with hydrochloric acid to produce a pregnant leach solution; (iii) Passing the pregnant leach solution from step (ii) to a series of impurity removal steps in which impurities including iron, calcium and sodium are substantially removed; and (iv) Passing the purified lithium chloride product of step (iii) to an electrolysis step thereby producing a lithium hydroxide solution.
