Ilmenite
Ilmenite, also known as manaccanite, is a titaniumiron oxide mineral with the idealized formula FeTiO is a weakly magnetic black or steelgray solid. From a commercial perspective, ilmenite is the most important ore of titanium. Ilmenite is the main source of titanium dioxide, which is used in paints, inks, fabrics, plastics, paper, sunscreen, food and cosmetics.

Separation of ilmenite and rutile
The latter is then roasted at an elevated temperature in a hydrous atmosphere to convert the ilmenite to a magnetic material. Thereafter the ilmenite may then be subjected to a magnetic separation whereby nonmagnetic rutile may be recovered while the magnetic portion is recycled for further separation.
