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 …

Physical Properties Of Ilmenite. Ilmenite is a black mineral found in mafic igneous rocks and pegmatites. It belongs to the iron titanium oxide minerals group, which also includes rutile, anatase, brookite, and perovskite. Ilmenite has a hardness of 5.5-6 on the Mohs scale, making it durable enough for use as an abrasive or gemstone polish.
