Gravity separation techniques like Jigging and Heavy Media Separation (HMS) were conducted on a coking coal sample from Assam. Chemical analysis of the sample showed 14.68% ash, 35.02% volatile matter, 47.74% fixed carbon and 2.56% moisture. The objective of the studies was to lower the ash content by adopting Jigging as well as Heavy Media Separation techniques. The studies were conducted in a mineral jig and HMS was at 1.4-1.8 Sp.Gr by using organic liquid. It was found that at -6.3 + 4.0 mm size, the ash was reduced to 1.89% and 1.91% by Jigging and HMS respectively. Both the techniques were comparable and found suitable for reducing the ash content to the lowest possible level.
