Ilmenite is a black, iron-titanium oxide mineral with the chemical formula FeTiO3. It is primarily found in igneous and metamorphic rocks and is a significant source of titanium. This mineral is often mined for its titanium content, which is used in various applications, including the production of titanium dioxide, a white pigment used in paints, plastics, and paper. In addition to its industrial uses, ilmenite is also important in the field of geology. It can provide insights into the formation and evolution of the Earth's crust. The mineral is commonly associated with other minerals such as magnetite and hematite, which can also be sources of iron.
