| Description |
The paper presents the results of beneficiation and purification of a low grade and finely disseminated graphite sample from Palamu district of Jharkhand. The sample
contained 8.46% fixed carbon with 85.75% ash. Beneficiation and purification of the
sample were attempted by physical, physico-chemical and chemical methods. Froth
flotation of the ground sample led to enrichment of graphite above 96% fixed carbon
centent. Further purificatin of the graphite flotation concentrate by chemical method
involving alkali roasting followed by hydrochloric acid leaching resulted in product
assaying 98.4% fixed carbon.
