The Kollam coastline is rich in minerals like ilmenite, rutile, zircon, monazite, leucoxene, sillimanite and garnet.
Kyanite, as a sources of aluminium, and Leucoxene, as a substitute of rutile, Beach sand containing potentially valuable minerals were discovered in 1961 during a geological survey for radioactive minerals in cox;sbazar beach area .Atomic energy commission have been engaged for its exploration and exploitation of these minerals ,according to baec data there is 4.4 million tons of heavy minerals on 17 nos deposits area so far .
Titanium (as ilmenite, leucoxene and rutile) - 682.30 million tonne
The rocks comprise plagioclase, perthite, quartz, and small amounts of biotite, opaque oxide, titanite, rare allanite, and secondary chlorite (after biotite), leucoxene and epidote.
The market research company, Ceresana extensively analyzed the global market for titanium dioxide along the complete value-added chain already for the second time: from the feedstock ilmenite, leucoxene, and rutile to the refined intermediates titanium slag and synthetic rutile up to the individual end products.
Secondary minerals in these rocks include chlorite, calcite, Iron hydroxide, opaque mineral, Leucoxene and quartz.
It also produced a large bulk sample of heavy mineral concentrate from which zircon and the titanium minerals, ilmenite and leucoxene, can be recovered in a separate operation.
Abundant leucoxene is noted in many of the holes as are thin porphyries.
Monazite sampling exceeded 48%-50%, and valuable heavy minerals included zircon, leucoxene and ilmenite.
Titanium dioxide is mined from either the natural ores of ilmenite and leucoxene or rutile beach sand.
Extracted from bowels titanium ores are either dressed with production of selective ilmenite, rutile, anatase, and leucoxene concentrates, containing up to 45-70 % [TiO.sub.2], or subjected to melting with output of titanium slag (up to 85 % [TiO.sub.2]) and cast iron, or processed into synthetic rutile.
