    Most ilmenite is mined for titanium dioxide production. In 2011, about 47% of the titanium dioxide produced worldwide was produced from this material. Ilmenite and/or titanium dioxide are used in the production of titanium metal. Titanium dioxide is most used as a white pigment and the major consuming industries for TiO2 pigments are paints and surface coatings, plastics, and paper and paperboard.
