India has a vast resource of beach sand minerals along the Eastern and the Western coastal lines. The Beach Sand Minerals are usually heavier due to higher specific gravity and because of this property these are also known as Heavy Minerals. The Heavy Minerals are themselves a mixture of a variety of minerals like monazite, ilntenite, rutile , zircon. silimanite, garner etc.
