Description Gondwana coal makes up to 98 per cent of the total reserves and 99 per cent of the production of coal in India. These coals are intimately mixed with mineral matter, causing a high level of impurities in the run-of –mine (ROM) coal. Beneficiation of high – ash non-coking coals of India has become the prerequisite for improving the overall economics and efficiency for downstream utilization industries. The association between specific mineral and organic constituents in a typical non-coking coal sample form the Eastern Coalfields, India was studied. For this, raw coals were fractionated by size and density and the variation of major minerals with respect to size and density was examined. Mineral species were identified by X-ray diffraction. The results showed that the concentration of quartz and kaolinite increases with increase of gravity of the coal while concentration of siderite is much lower size fractions of the coal.
