Extraction of titanium metal relies greatly on two principal titanium ores: ilmenite and rutile. Titanium dioxide, a material greatly used in production of pigments, coatings, and as an automotive and aeronautical industry material, exists due to the two minerals. Rutile and ilmenite have very diverse composition, physical properties, and ...
