Compared with dry milling operation, wet milling is more effective, the particle size distribution of wet-milled ilmenite was much narrower, smaller, and more uniform. Wet milling of ilmenite makes the leaching reaction with dilute acid (60 wt% H 2 SO 4) practicable and the re-use of spend acid becomes possible and economical.

Ilmenite is a titanium-iron oxide mineral with the chemical formula FeTiO3. It is commonly found in igneous rocks and sediments, and is the primary ore of titanium. Ilmenite is typically black or dark brown in color, with a metallic luster and a submetallic to opaque appearance. It has a Mohs hardness of 5-6 and a specific gravity of 4.5-5.0.

The amount of iron in the rutile (or from the body) determines the degree of blue since its reduction to FeO is a key to the effect. Since rutile is variable in makeup, changes in the iron content will change the blue color. The fact that titanium dioxide additions do not make good blues suggests that the iron-titanium mix is the key to good color.
