Abstract
A process for the extraction of lithium from a brine, wherein a solution of the brine is contacted with a titanate adsorbent such that lithium ions are adsorbed thereon whilst rejecting substantially all other cations. The adsorbent is provided in the form of either a hydrated titanium dioxide or a sodium titanate. The process in turn produces a substantially pure lithium chloride solution.
Claims15
A process for extraction of lithium from a brine, wherein a solution of the brine is contacted with a sodium titanate adsorbent, such that lithium ions are adsorbed thereon whilst rejecting substantially all other cations, the adsorbent being regenerated through addition of a hydrochloric acid solution whereby the adsorbed lithium ions are extracted, thereby producing a substantially pure lithium chloride solution.
