English Abstract

Note: The Abstract is shown in the official language in which it was submitted.



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 TiO2 or solvent extract and thermal stripping. TiO2 may also be separated
in the initial leach solution. Preferably, the titanium halide is titanium
tetrachloride.
