Ilmenite - Wikipedia

Ilmenite, also known as manaccanite, is a titanium-iron oxide mineral with the idealized formula FeTiO 3.It is a weakly magnetic black or steel-gray 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, printing inks, fabrics, plastics, paper, sunscreen, food and cosmetics.

Jul 18, 2013· AbstractReductive roasting of ilmenite ore by carbon in the presence of sodium carbonate was carried out at 1000–1200°C for periods of up to 180 min. Additions of sodium carbonate of up to 30 wt% of the ore enhanced the reduction efficiency. The maximum metallization obtained at 1200°C was about 85%, and the rest of the iron exists in the form of sodium-iron-titanates.
