Ilmenite is converted into pigment grade titanium dioxide via either the sulfate process or the chloride process. Both sulfate and chloride processes produce the titanium dioxide pigment in the rutile crystal form, but the Sulfate Process can be adjusted to produce the anatase form. Anatase, being softer, is used in fiber and paper applications.

Ilmenite (FeO.TiO2) and rutile (TiO2) are the two dominant resources minerals of titanium. In the conventional process, a large fraction of ilmenite is being rejected un-dissolved and the co-dissolved other transition metal ions may be co-precipitated with titanium, which may seriously discolor the white pigment color of titanium dioxide.
