About Ilmenite & Titanium. Ilmenite is a common accessory mineral in igneous rocks, sediments, and sedimentary rocks in many parts of the world. It is an oxide mineral of iron and titanium, also known as titanium magnetite, and its composition is FeTiO3. Ilmenite is a heavy (specific gravity 4.7), moderately hard (Mohs hardness 5.6 to 6), opaque black …

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.

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

Another important parameter for the processing of ilmenite is the agitating speed. When the agitating speed is increased from 100 to 500 rpm in 100 rpm increments, the maximum percentage of titanium and iron was leached at 400 rpm and remained the same at 500 rpm. The temperature was found to affect the dissolution of ilmenite and …
