Ilmenite - Cargo Handbook - the world's largest cargo ...

Of all of these minerals, only rutile, with a formula of TiO 2, competes with ilmenite for dominance in the titanium source department. Even though rutile is the more common mineral and has a higher percentage of titanium in its formula, it is not concentrated in igneous deposits like ilmenite and is therefore less useful as an ore.

Due to the scarcity of natural raw mineral rutile (TiO 2), ilmenite is considered as precursor for the extraction of TiO 2. Ilmenite is reduced at the initial stage for the conversion of complex iron oxide into simpler form. Therefore, pre-reduction of ilmenite concentrate is essential to minimize the energy consumption during thermal plasma ...

Ilmenite - an overview | ScienceDirect Topics

Ilmenite (FeTiO 3) and rutile (TiO 2) are the most important ores used as raw material for TiO 2. Although natural rutile contains a high amount of TiO 2 with low level of impurities, the mineral is becoming scarce and thus more costly. Consequently, ilmenite is currently favored despite its relatively low TiO 2 content (approximately 50% TiO 2 ...
