“…Processing noncoking coal through beneficiation is the best assured way of quality adherence and maintaining consistency in quality supply. Keeping this in view, a detailed laboratory investigation on the cleaning potential of Samleshwari coal was carried out and presented elsewhere [5]. The study revealed that a theoretical yield of 58% on a combined basis was achievable at 34% ash level, the corresponding reject ash being 72%.…”

Coal will continue to play an important role in overall energy scenario in India. Despite its high-ash content, the run-of-mine (ROM) Indian coals are used directly for thermal power generation. There is an urgent need to improve quality of coal by reducing ash so that a consistent supply of quality coal can be supplied to the power plants. Pilot-scale studies were conducted on beneficiation of High Ash Indian Non Coking Coal obtained from the Samleshwari mines using a 20-t/h Baum Jig Washer. The results of the pilot-scale studies revealed that the ROM coal, containing 50% ash content, could be cleaned with the Baum jig providing a clean coal containing 36% ash at a yield of 52%.
