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 …

Based on reported data through October 2019, the estimated value of titanium mineral and synthetic concentrates imported into the United States in 2019 was $840 million. Zircon was a coproduct of mining from ilmenite and rutile deposits. About 90% of titanium mineral concentrates were consumed by domestic titanium dioxide (TiO2) pigment producers.

Granular ilmenite is the main mineral used for the recovery of titanium. Granular ilmenite is often associated with titanomagnetite, or distributed in silicate mineral grains, and forms via automorphism and semiautomorphism processes. It has coarse granules and is easily broken and dissociated. Granular ilmenite is about 90% of total ilmenite ...
