A lithium hydroxide production process integrating a lithium stripping stage with a lithium hydroxide production process performed in a two-compartment electrolysis cell.

Integrated lithium production process

A method of selectively separating ions, including: (a) providing a reverse osmosis (RO) separation arrangement having an RO membrane; (b) introducing a feed brine to the RO membrane, the brine containing multivalent cations, alkali cations and halide anions, a total concentration of the alkali cations and halide anions being at least 4%, by weight of the feed brine; (c) applying a sub-osmotic pressure to the feed brine, to drive a first portion of the brine through the RO membrane to produce a permeate solution, a remainder of the feed brine being rejected by the RO membrane and being discharged as a reject solution; the sub-osmotic pressure being applied so as to preferentially distribute the multivalent cations to the reject solution, with respect to the permeate solution; the sub-osmotic pressure being less than 0.9 times a measured or theoretical osmotic pressure of the feed brine.

Selective separation process

Provided are continuous methods and processes for removing Li ions from an aqueous feed solution.

Processes for metal ions removal from aqueous solutions

A method of purifying phosphoric acid solution produced in wet process using nanofiltration. The claimed method contains the following: (a) providing wet phosphoric feed (b) subjecting the said feed to a first nanofilter (c) produce sulfate solids (d) removing the solids (e) subjecting a second nanofilter.
