· Reduction of ilmenite by solid-state reaction In recent years titania (TiO2) as a slag has been produced by smelting ilmenite with coke in an electric furnace. Numerous publications are available on the commercial technique for slag preparation (Armant and Cole, 1949; Stoddard et al., 1950; Stoddard and Wyatt, 1953, 1955;

· Titania can be produced from ilmenite, rutile, anatase, brookite, titanite, and titanomagnetite. However, the main raw materials are ilmenite and rutile. Since the TiO 2 content of rutile is more than 95%, it can be fed directly to the chlorination process to produce titania or titanium chloride as a precursor for titanium metal production.
