Intergrowths in ilmenite of the beach sands of Kerala (1965)

The proportion of ihnenite grains with and without intergrowths and the probable origin of the intergrowths and their effect on the marketability of ihnenite concen-trates are discussed inthe paper. I NDIA is one of the largest producers of ilmenite sand and the beach sand deposits of Kerala are world-famous for their high heavy-mineral content.

Heavy Minerals and the Characters of Ilmenite in the Beach

Indian beach placer sand deposits are, in general, ilmenite-rich. However, some concentrations are dominated by pyriboles. The Chavakkad-Ponnani (CP) area along the northern Kerala coast is one such deposit. This paper deals with the general character of the heavy minerals of CP with special emphasis on the characters of ilmenite. Most Indian beach sand ilmenites are of good quality.
