ILMENITE.

 

Ilmenite deposits occur extensively in the form of alluvial deposit on the beach sands of Kerala, Tamil Nadu and Orissa coasts, as black, heavy sand, along with monazite, zircon, garnet and other heavy minerals. The volume and degree of concentration of heavy mineral grains are on a scale unknown elsewhere.

Patches of the sand concentrates occur at Ratnagiri and further north on the Malabar coast and also on the east coast at Tuticorin, Visakhapatnam.

Form

Occurs in polymorphic forms as rutile and anatase

Content

Titani ferrous ore, (FeO TiO2) containing 50 to 60 percent of titanium dioxide

Application

 

Ilmenite is used to produce a number of products such as synthetic rutile, titanium tetrachloride, titanium dioxide, titania slag etc.

Process outline


Ilmenite deposits occur as black, heavy sand, along with monazite, zircon, garnet and other heavy minerals.

Ilmenite has to be separated from the deposits in mineral separation plant.
