Raw coal fed on to the vibrating bed having crosswise and vertical slope. Air supplied through air holes in the beneficiation bed which agitates the raw coal resulting in stratification of coal as per its relative densities -lighter coal forms the upper layer and heavier coal forms the lower layer. Upper good coal

In the last few years, dry concentration has played an important role in coal beneficiation, due to the increase in its separation efficiency, as well as the non-use of water [13,14].
Fly Ash Fly ash is one of the residues generated in the combustion of coal. The components and the properties of fly ash vary considerably depending on the variety of coal, extend to which it is being burnt, design of the boiler unit, degree of pulverization, storage methods Etc. Around 70 tonnes of fly ash is being produced at Century Rayon.

May 07, 2007· The wet beneficiation process for coal cleaning is currently the predominant method of purification of coal in the world. However, dry beneficiation of coal has obvious advantages over wet processes. The dry processes for coal are based on the physical properties of coal and its
1. RATIONALE FOR COAL BENEFICIATION. The intrinsic quality of Indian coal, along with the dominant practice of open cast mining, has meant that run of the mine (ROM) Indian non-coking coal contains a huge share of ash and other minerals. ROM coal typically has high ash content from 30-50 percent and low calorific value (2,500-5,000 kcal/kg).
States has far more coal than gas and petroleum (compare Figures 7-1, 8-1 and 9-1). This suggests that, when supplies of gas and petroleum become scarce, it would be possible to turn to coal as our major fossil fuel energy resource. How long could we rely on domestic supplies of coal? There are many uncertainties involved in making such an
