A Review on the Recovery of Titanium Dioxide from Ilmenite Ores …
The effect of several factors on the acid leaching kinetics in reported processes was reviewed. Temperature, time and acid concentration significantly affect the dissolution of titanium and impurities in ilmenite. The addition of either iron powder or chloride/sulfate salts affects significantly the leaching rate of ilmenite.

Mineral Separation and Characterization of the Ilmenite …
ilmenite (60% - 75% TiO2), leucoxene (76% - 90% TiO2) and rutile (95% TiO2) [7]. On the other hand, in alluvial sediments, ilmenite alters and Fe is partially leached in a conti nuous process going to pseudorutile (Fe2Ti3O9) and leucoxene [8]. For that reason, titanium and iron content in the ilmenite may vary significantly, as it can be

A Review of the Solid-State Reduction Aspects of Ilmenite …
ABSTRACT. Various pyrometallurgical processes to produce TiO 2 slag have been reviewed, focusing on the solid-state reduction aspects of ilmenite. Most of the upgradation processes from ilmenite to titania slag involve direct smelting of ilmenite and, therefore, are generally considered energy-intensive and not environmentally friendly.
