extracting titanium from ilmenite
Titanium: Kroll Method
Ilmenite, also known as manaccanite, is a titanium-iron oxide mineral with the idealized formula FeTiO 3 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.
