9Clean coal technology being practised in coal washeries in India, as pre-combustion clean coal technology, mainly focus on cleaning of coal by removing ash from coal 9Earlier only coking coal was being washed because steel making needs coking coal of ash of 17 to 18. The raw coal ash in Indian coking coal varies from 25 to 30. Now-a-days, Min.
Coal washing, or coal beneficiation, is widely seen as an efficient method for getting the most from run-of-mine coal. On the other hand, it is a water-intensive process typically, washing one ton of coal consumes about 45 m 3 liters of water.

Princes Magnafloat is perfectly suited for the beneficiation of run of mine coal. Magnafloat is a heavy media for coal separation. Prince Magnafloat , a naturally magnetic and high-density magnetite product, is the ideal solution for the coal washing process because of its high magnetics, density, and its higher stability in suspension.
Even today, traditional coal beneficiation is performed using coal washing with large amounts of water. It is then necessary to expend considerable energy drying the coal again. Moreover, in many regions of the world water is rare, and it is becoming more difficult for mines to obtain licenses for its use.
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
Four Categories of Clean Coal Technologies. Pre-combustion These are technologies that are used to clean the coal before it is burned. They include actual physical cleaning or washing, chemical cleaning and new biological methods of cleaning to remove sulfur and ash. All types of coal cleaning are often call coal beneficiation.
