Abstract
Samples from the Kaolinite deposits at Bagru Hills, Lohardaga, Bihar have heavy mineral assemblage of rutile, opaque, tourmaline, biotite, staurolite, pyroxene, sphene, epidote, zircon, kyanite, muscovite and tremolite/actinolite derived from igneous and metamorphic sources. The lighter fraction includes iron hydroxides, chlorite, feldspar, carbonate and some muscovite or limonite. The major, minor and trace elements remain nearly the same irrespective of colouration of samples. The chemical composition and the size of the kaolinite grains coupled with its purity clearly indicate that it can be used in a number of industries.
