What is Ilmenite and Its Properties?

Ilmenite, with the chemical formula FeTiO3, is a mineral belonging to the R&D (Rutile-Ilmenite-Geikielite) series. It is an oxide mineral containing iron (Fe), titanium (Ti), and oxygen (O). Typically found in igneous rocks, it is a significant ore of titanium. Ilmenite is most commonly found in black sands deposited on beaches and in alluvial deposits, originating from the weathering of titanium-bearing rocks. It crystallizes in the trigonal system and is opaque with a metallic lustre, often appearing dark grey to black. Its hardness is between 5 and 6 on the Mohs scale, and its specific gravity ranges from 4.70 to 4.79.

The industrial importance of ilmenite stems from its high titanium content, typically around 31.5% iron and 31.6% titanium dioxide by weight, although natural variations exist. It is often found in association with other minerals like rutile, zircon, and monazite, which are separated through physical processing methods such as gravity separation, magnetic separation, and flotation. While rutile is a richer source of titanium dioxide (TiO2) and commands a higher price, ilmenite is more abundant, making it the most economically important titanium ore globally. Its properties make it suitable for a range of industrial applications, most notably in the production of titanium dioxide pigment and metallic titanium.

Ilmenite as a Source of Titanium Dioxide (TiO2)

The vast majority of ilmenite consumed globally is used to produce titanium dioxide (TiO2), a brilliant white pigment prized for its opacity, brightness, and UV resistance. The production process typically involves either the sulfate process or the chloride process. In the sulfate process, ilmenite ore is digested with sulfuric acid, followed by a series of purification steps to yield high-purity TiO2.
