Ilmenite reduction, specifically for secondary ilmenites, plays a critical role in the production of synthetic rutile via the Becher process (Becher et al., 1965).This process relies on coal as the primary reducing agent and is critical for upgrading titanium-bearing minerals into synthetic rutile, a valuable raw material for the titanium pigment industry.

2.1 Manufacturing. 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 compared …
