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 to selectively remove iron values to provide high purity iron products. Titanium may be separated from raffinate as TiO or solvent extract and thermal stripping. TiO may also be separated in the initial leach solution. Preferably, the titanium halide is titanium tetrachloride.
