ilmenitelike

Ilmenite is a mineral with the chemical formula FeTiO3. It is an important ore of titanium and iron. Ilmenite is a member of the ilmenite group, which consists of several related minerals. It is a black or brownish-black solid. In its pure form, ilmenite has a theoretical composition of 31.6% iron, 31.1% titanium, and 37.3% oxygen. However, natural ilmenite often contains impurities, such as manganese, magnesium, and niobium, which can substitute for iron or titanium in the crystal structure.

Ilmenite is found in a variety of geological settings. It is commonly associated with igneous rocks, particularly mafic and ultramafic intrusions, and is also found in metamorphic rocks. Significant deposits of ilmenite are often found in placer deposits, which are accumulations of heavy minerals eroded from their source rocks and transported by rivers or ocean currents. These placer deposits are the primary source for commercial extraction of titanium.

The main uses of ilmenite are as a source of titanium dioxide (TiO2), which is used as a white pigment in paints, plastics, paper, and cosmetics. Titanium metal, derived from ilmenite, is known for its high strength-to-weight ratio and corrosion resistance, making it valuable in aerospace, medical implants, and sporting goods. Iron is also recovered as a byproduct of ilmenite processing.
