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.

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.
