A New Approach to Processing Rutile from Ilmenite Ore
Rutile (TiO2) is a vital industrial material used in pigments and in many other valuable chemicals. A new production process to synthesize rutile from natural ilmenite ore and therefore overcome the environmental problems associated with conventional rutile extraction processes was developed. Because the simple phase separation of ilmenite …

Ilmenite
Like rutile, ilmenite is quite variable in nature. Actually, more variable since it would likely come from the same deposit, it being the more iron-stained part. You can tell the difference between granular rutile and granular ilmenite by doing a smear test against an abrasive surface (i.e. an unglazed white tile). ... Related Information. Tap ...

Methods of Extracting TiO2 and Other Related Compounds from Ilmenite
Although ilmenite and rutile are extensively used to extract TiO2 at the industrial level, through the sulphate and chloride processes, they can also be recognized to possess the potential to be employed as the raw material to synthesize other titanium compounds as well. The Pulmoddai mineral sand deposit in Sri Lanka is considered as a …
Effect of ilmenite properties on synthetic rutile quality
Ilmenite (TiO 2 > 52%) can be upgraded to synthetic rutile (TiO 2 > 88%) using a reduction and leaching process. Australian ilmenites (FeTiO 3) contain variable amounts of titanium dioxide, iron oxide and other impurities.Ilmenites from different deposits can have different physical and chemical properties that affect ilmenite reduction and the …

Abstract Garnet is a common metamorphic and igneous mineral with extensive solid solution that can be stable to mantle depths ≥400 km. High-T and/or high-P garnet may contain oriented lamellae of other minerals, most commonly simple oxides (e.g., rutile, ilmenite), apatite, and, in ultrahigh-P cases, silicates including pyroxene and amphibole.
