Ilmenite is a naturally occurring mineral composed primarily of titanium dioxide (TiO2) and iron (Fe). It is recognized for its distinctive black to dark brown color and is an essential source of titanium, a key element in various industrial applications. Ilmenite is widely used in the production of titanium dioxide pigments, titanium metal, and as a feedstock for the production of titanium sponge, which is further processed into various products, including aerospace components, medical implants, and corrosion-resistant alloys. Its versatility and titanium content make it a valuable mineral in industries ranging from paints and coatings to aerospace and metallurgy.
