Leaching of ilmenite to produce titanium based materials: a …
Titanium is the ninth most abundant element in the Earth's crust and it is present mainly in the form of ilmenite (40–80% TiO 2), rutile (~ 95% TiO 2), anatase (> 95% TiO 2), and leucoxene (> 65% TiO 2) [35,36,37,38].Major ilmenite deposits of the world are found in countries such as Australia (eastern and western coast), South Africa …

Rutile
Rutile is the mineral name for natural crystals of titanium dioxide. However in nature rutile is always contaminated by other minerals (especially iron but also things like tantalum, niobium, chromium and tin, the analysis provided here is obviously a simplification). In ceramics, the term 'rutile' is generally understood to refer to the brown ...

A NEW PROCESS TO UPGRADE ILMENITE TO SYNTHETIC RUTILE
Ilmenite occurs in black sand at the mouth of great rivers as in India, or as massive deposits like in Quebec Province in Canada. It is unsuitable for processing into pigment or for metal production because of its high iron content and its low grade. Pyrometallurgical and hydrometallurgical methods have been developed to cope with this problem which …
