Titanium dioxide - Wikipedia

OverviewProductionApplicationsResearchHealth and safetyTitanium dioxide, also known as titanium oxide or titania /taɪˈteɪniə/, is the naturally occurring oxide of titanium, chemical formula TiO 2. When used as a pigment, it is called titanium white, Pigment White 6, or CI 77891. Generally, it is sourced from ilmenite, rutile, and anatase. It has a wide range of applications, including paint, sunscreen, and food coloring. When used as a food coloring, it has E number E171. World production in 2014 exceeded 9 million tonnes. It has bee

This invention relates to a process for separating rutile and ilmenite from ilmenite leach tails and is effected by treating the leach tails from an acidic leach to a flotation step whereby gangue is separated from the unreacted ilmenite and rutile. The latter is then roasted at an elevated temperature in a hydrous atmosphere to convert the ilmenite to a magnetic material.

Preparation and Photocatalytic Performance of Nano-TiO2 ...

Nanoscale titanium dioxide (nano-TiO 2 ) was modified via metal doping to improve its photocatalytic activity and utilization of visible light. Nano-TiO 2 doped with iron III (Fe 3+ ) only, lanthanum III (La 3+ ) only, and both Fe 3+ /La 3+ was prepared using the sol-gel method. The photocatalytic activities of the three forms of doped nano-TiO2 were evaluated.

Titanium Ore Processing and Beneficiation

Low intensity magnetic separation pulls out metallic iron and magnetite. The concentrates pass through a high intensity magnetic separator to pull out the ilmen­ite fraction—46 to 48% TiO2. The non-magnetic frac­tion is subjected to high intensity electrostatic separa­tion which removes the high grade rutile—94-95% TiO2.
