Leucoxene is a fine granular alteration product of titanium minerals. It varies in colour from yellow to brown.
It is not a valid mineral species and consists mainly of rutile or anatase. It is observed in some igneous rocks and iron ore deposits as the result of the alteration of ilmenite, perovskite, or titanite.
The sands of Sankaramangalam in Kerala were found to contain several rare earths like Ilmenite, Zircon and Rutile. KMML is involved in the harvesting of these minerals from the seas, which are used as basic raw materials for a variety of industries. The Mineral Separation Unit (MS Unit) is engaged in the separation of Ilmenite, Rutile, Leucoxene, Monazite, Silliminite etc from the beach sand. The MS Unit employs Gravitational, Magnetic and High Tension Electrostatic Techniques for separation of minerals from the sand.
