ABSTRACT:
A process for the removal of iron and titanium minerals from aluminum bearing materials in at least one chlorination stage by the use of an excess of aluminum trichloride as at least the major chlorinating agent for the contained iron and titanium minerals, condensing the excess aluminum trichloride to recover the aluminum trichloride in an impure form, and recycling the impure aluminum trichloride to the chlorination stage together with additional aluminum trichloride or starvation amounts of chlorine, or alternately additional amounts of aluminum trichloride and starvation amounts of chlorine.
