Rutile - Wikipedia

Rutile is a common accessory mineral in high-temperature and high-pressure metamorphic rocks and in igneous rocks.. Thermodynamically, rutile is the most stable polymorph of TiO 2 at all temperatures, exhibiting lower total free energy than metastable phases of anatase or brookite. Consequently, the transformation of the metastable TiO 2 polymorphs to rutile is irreversible.

Rutile and ilmenite in Australia - Chem Link

Synthetic rutile can be produced from naturally occurring ilmenite which is a complex oxide with iron. Rutile is used in the manufacture of titanium dioxide pigment. In Australia most rutile is produced from ilmenite as it naturally occurs in accessible high concentrations and in a form which allows the ready extraction of the rutile.

However, a natural rutile or synthetic rutile (SR) with a TiO 2 content of at least 88% is required in the chlorination process. Since the reserves of natural rutile is only one-tenth of the ilmenite reserves, development of various synthetic rutile preparation technologies using ilmenite has been attracting widespread attention.
