Ilmenite and Rutile: Rich Sources of Titanium

Ilmenite and rutile are both rich sources of titanium. Ilmenite is an iron titanium oxide (FeTiO3), and rutile is a titanium dioxide mineral (TiO2). They are abundantly available in certain coastal tracts of India, particularly in the states of Tamil Nadu, Kerala, and Andhra Pradesh.

Titanium is a strong, lightweight, and corrosion-resistant metal, making it ideal for use in various industries, such as aerospace, automotive, and construction. It is also used in the production of pigments, coatings, and other applications.
