Abstract
A method for the production of titanium metal from titanium-bearing ore. The method comprises leaching said ore or a concentrate thereof with an aqueous solution of a hydrogen halide; separating solids from the leach solution, to provide a leachate solution. The leachate solution may be subjected to extraction with an immiscible organic phase. Titanium halide is separated from the organic phase by stripping. Preferably, the titanium halide is titanium tetrachloride.
