Rutile (TiO2) is heavily used in pigments and colorants, and the most abundant source of rutile is ilmenite. Upon oxidation of ilmenite, rutile can be formed with modest energy consumption; furthermore, after leaching, only a few byproducts are formed. Unfortunately, one drawback is the necessarily long oxidative process of typically used …

Cardarelli (2008) (p. 277) states that "ilmenite from massive hard-rock anorthosite complexes always contains less TiO 2 than theoretical stoichiometric ilmenite (i.e., 52.6 wt% TiO 2)" resulting in "industrial ilmenite concentrates [that] contain as much as 32 to 46 wt% TiO 2 ". Charlier et al. (2015) has summarized the TiO 2 content of …
Ilmenite is the iron–titanium oxide mineral with an idealized composition of FeTiO3 (FeO·TiO 2), which is usually used as the main source of Titanium dioxide. The researchers from Chalmers University of Technology conducted the pioneer works of CLC with ilmenite as oxygen carrier [106–110].
at Tellnes, Norway, processing 200,000 tpa of high titania hard rock (44% TiO 2) to produce a titanium concentrate (Figure 3). Power costs are low providing a significant OPEX advantage. Tinfos also imports ilmenite mineral sands concentrate and uses its own
Solidification usually produces igneous masses with ilmenite-enriched layers. Then, as the host rock eventually weathers and erodes, the freed ilmenite particles concentrate in alluvial deposits. Placer miners know that the black sands in gold-pan and sluice concentrates often consist largely of ilmenite.
