The Tiwest Joint Venture was a mining and processing company, established in 1988, to extract ilmenite, rutile, leucoxene and zircon from a mineral sands deposit at Cooljarloo, 14 km north of Cataby, Western Australia.
[1][citation needed] Tiwest's corporate office (sales/marketing/accounting/administration/IT/etc) was located in Bentley, five minutes drive south of the Perth central business district.
Most synthetic rutile from Chandala was then trucked to Kwinana, 30 km south of Perth, to the Tiwest-owned pigment plant, which produces titanium dioxide a.k.a.
TiO2 is the best[citation needed] commercially viable whiting agent known, and is typically used in the manufacture of paints, plastics, and food stuffs.
As part of the 2012 acquisition,[2] the assets of the TIWEST Joint Venture have been folded into the sole parent company, Tronox, which continues to operate in the mineral-sands industry.
