Titanium | Geoscience Australia

Ilmenite grains are converted to porous synthetic rutile grains with metallic iron and other impurity inclusions. The iron is precipitated as hydrated iron oxide from the synthetic rutile grains and a mild acid treatment is used to dissolve the impurities and any residual iron.

Ilmenite - an overview | ScienceDirect Topics

There is an abundant source of raw titanium oxide such as rutile and ilmenite in the Earth's crust; however, these oxides are thermodynamically more stable (i.e. high enthalpy of formation of its oxide) than other commodity metal oxides such as alumina and iron oxides. Therefore, it is more difficult to extract Ti from its oxide, which is a ...

ILMENITE (Iron Titanium Oxide) - galleries.com

Ilmenite by itself is not a profitable iron ore as the titanium inhibits the smelting process. Ilmenite, hematite and corundum all have similar structures and belong to a more or less informal group called the Hematite Group with a general formula of A 2 O 3. The structure is composed of alternating layers of cations and oxygens.
