Rutile, the high temperature TiO 2 polymorph, is a common accessory mineral in metamorphic and hydrothermally-altered rocks associated with ore mineralisation and it forms in highly oxidised environments (Dachille et al., 1968, Smith et al., 2009, Hanaor and Sorrell, 2011).Trace elements incorporated in the rutile structure …
Australian mineral facts | Geoscience Australia
From these minerals, useful materials such as metals can be extracted. Australia is one of the world's leading producers of bauxite (aluminium ore), iron ore, lithium, gold, lead, diamond, rare earth elements, uranium, and zinc. Australia also has large mineral sand deposits of ilmenite, zircon and rutile.

The reason behind this is that ilmenite is produced from 54% titanium oxide with a higher ore grade where rutile is produced from 95% titanium oxide with lower ore grade. Extracting the low-grade rutile is more energy intensive than extracting the higher-grade ilmenite in addition to the fact that rutile is extracted from deep mines.
