Abstract: PCT No. PCT/AU94/00241 Sec. 371 Date Apr. 1, 1996 Sec. 102(e) Date Apr. 1, 1996 PCT Filed May 9, 1994 PCT Pub. No. WO94/26944 PCT Pub. Date Nov. 24, 1994A process for removing impurities from a titaniferous material that has been subjected to thermal reduction and which includes a titaniferous phase of general formula M3O5. The thermally reduced titaniferous material is subjected to a secondary heat treatment to covert the M3O5 phase to a more readily leachable M2O3 phase. This material is then cooled and leached in an aqueous acid solution containing hydrochloric acid or sulfuric acid, and the leachate is separated from the titaniferous material to form a purified titaniferous material.
