2014-1-10 · Ilmenite (FeO·TiO 2) and rutile (TiO 2) are well-known minerals for titanium.Ilmenite is far more abundant than rutile in nature. However, ilmenite contains iron oxides and the TiO 2 content of ilmenite is considerably less than rutile. Hence it is necessary to upgrade (enhance TiO 2 content) Ilmenite by removing iron before it could be processed for recovery of pure TiO 2
