  • The Valuable Minerals in Heavy Mineral Sands Rutile

    Rutile has a theoretical TiO2 content of 100%, however impurities such as iron typically reduce this to 9397%. TiO2 can also exist as anatase, which has a different crystal structure to rutile. Anatase is primarily used in paper rather than paints and plastics. Anatase is able to convert light into an electrical charge.
