Ilmenite is a non-fluorescent, weakly magnetic titanium-iron oxide mineral which is iron-black or steel-grey. It is a crystalline iron titanium oxide (FeTiO3). Ilmenite is a common accessory mineral found in metamorphic and igneous rocks and concentrated in placer mines as “black sand” deposits.
Category: oxide minerals. Formula: iron titanium oxide, FeTiO3. Colour: Iron-black; grey with a brownish tint in reflected light. Chrystal habit: granular to massive and lamellar exsolutions in hematite or magnetite.
Ilmenite accounts for about 90% of the world’s consumption of titanium minerals. Most ilmenite ore production is destined for titaniferrous slag application. Ilmenite can be further processed as pig iron, as continuous cast steel billets, or as iron or steel powders, or converted into molten iron bath and slag rich in titanium dioxide.
