Ilmenite. Ilmenite is an iron titanium oxide. It is the principal ore of titanium. It is black (or dark gray) and has a metallic luster. It is usually weakly magnetic. The mineral itself is actually not magnetic, but it is often intergrown with magnetite, which very strongly responds to the magnetic force. You can use a hand-held magnet to test ...Web

Ilmenite Mineral Description. Ilmenite is an iron-oxide mineral of the oxide and hydroxide group with structural formula (Fe,Ti) 2 O 3.The structure is similar to that of hematite, where the two Fe 3+ in hematite are replaced by one Fe 2+ and one Ti 4+ in ilmenite. It consists essentially of a dense arrangement of Fe 2+ and Ti 4+ ions in octahedral coordination …Web

Ilmenite is a combined oxide naturally occurring in the form FeTiO3, which is also the reduced form in CLC. The oxidized form is Fe 2 TiO 5 + TiO 2. It has also been shown that there is a migration of Fe to the surface; thus in practice ilmenite is in part an iron oxide material ( Adanez et al., 2010 ).Web
