Abstract:
The disclosure relates to methods for preparing lithium hydroxide. For example, such methods can comprise mixing a lithium-containing material with an acidic aqueous composition optionally comprising lithium sulfate and thereby obtaining a mixture; roasting the mixture under suitable conditions to obtain a roasted, lithium-containing material; leaching the roasted material under conditions suitable to obtain a first aqueous composition comprising lithium sulfate; submitting the first aqueous composition comprising lithium sulfate to an electromembrane process under suitable conditions for at least partial conversion of the lithium sulfate into lithium hydroxide and to obtain a second aqueous composition comprising lithium sulfate, the electromembrane process involving a hydrogen depolarized anode; optionally increasing concentration of acid in the second aqueous composition; and using the second aqueous composition comprising lithium sulfate as the acidic aqueous composition optionally comprising lithium sulfate for mixing with the lithium-containing material and to obtain the mixture.

Claim (Index 30):
The method of any one of  claims 25  to  28 , further comprises carrying out a solid-liquid separation (for example at a temperature of about 15\u00b0 C. to about 130\u00b0 C. or about 25\u00b0 C. to about 125\u00b0 C.) to recover said lithium sulfate, thereby obtaining said lithium sulfate and an acidic aqueous effective to be used for being mixed with a lithium-containing material.
