In order to produce high-grade titanium dioxide (95% TiO2) directly from a titanium ore using titanium scrap and iron chloride waste, chlorine recovery and selective chlorination processes were investigated. The mixture of titanium scrap and ferrous chloride in carbon crucible and titanium ore in quartz crucible were placed inside gas-tight quartz …
Of these minerals, only ilmenite, leucoxene, and rutile have significant economic importance. As a metal, titanium is well known for corrosion resistance and for its high strength-to-weight ratio. Approximately 95% of titanium is consumed in the form of titanium dioxide (TiO 2), a white pigment
Thermodynamic study of the chlorination reactions of oxides such as titanium oxides and iron oxides at elevated temperatures was carried out in order to consider the removal of iron from titanium ore using selective chlorination method. In particular, various chlorination reactions were analyzed by utilizing chemical potential …
Titanium occurs primarily in octahedral coordination, and like the Fe and Mn oxides, the structures of the various Ti oxide minerals can be described in terms of the different arrangements of the Ti-containing octahedra. The principal Ti minerals are listed in Table 5 ( Fitzpatrick and Chittleborough, 2002 ). Table 5.
Typical composition of titanium-iron oxide minerals on the FeO–Fe 2 O 3 –TiO 2 diagram (small dots), ... Most rutile-type titanium resources are low-grade primary ore, whose reserves account for 86% of the rutile resources and 14% of placer resources in China (Taylor et al., 2006).

Ilmenite is valued as an ore of titanium, selling a ton of ore on the basis of 59% to 60% titanic oxide, TiO2. Ilmenite is used for making titanium metal, as well as ferro-titanium, employed in making steel, and for making titanium-white, a white pigment used for paints with great covering power and durability.
Thermodynamically, the iron oxides and titanium oxides in the Ti ore can be considered to exist as a mixture of both oxides, because the Gibbs energy of formation of FeTiO 3 at 1100K is a small negative value, as shown in eq.
