A Review on Beneficiation Prospect of Some of the Graphite Deposits of Palamu District of Bihar

Abstract

Graphite constitutes one of the important minerals for the manufacture of special types of refractory materials. In nature it occurs both in crystalline as well as amorphous forms. It is reported to occur in almost every State of India. In Bihar economic deposits of graphite are confined to the district of Palamu only with some minor occurences in Monghyr and Ranchi districts. G.S.I has located some important workable deposits whose estimated total reserves amount to about 16 lakhs tonnes upto 20 meters depth. These depsits are poorer in grade but sometimes the fixed carbon content is of the order of 50% F.C. A few customary processing plants have also been put up by some private parties.
