Iluka Resources was formed in July 1998 in a merger between Westralian Sands and the titanium mineral business of RGC.

[2][3] Westralian Sands was established in 1954 but commenced operations in 1959 when it started mining and processing the Yoganup deposit near Capel in Western Australia.

[6] In March 2009, Iluka announced that it would bring forward the closure of one of the Synthetic Rutile kilns at the Narngulu operations and that 23 jobs would be lost.

[8] Iluka also commenced work in 2014 with Vale in relation to the potential commercialisation of a large titanium ore body, with rare earth elements, in Minas Gerais, Brazil.

Iluka conducts international exploration, including for selected non-mineral sands opportunities, mainly on its Australian tenements.
