Coal preparation, or beneficiation, is a series of operations that remove mineral matter (, ash) from coal. Preparation relies on different mechanical operations, which will not be discussed in detail, to perform the separation, such as size reduction, size classification, cleaning, dewatering and drying, waste disposal, and pollution control.
#0183;#32;There are, however, a variety of problems associated with the use of coal. Mining operations are hazardous. Each year hundreds of coal miners lose their lives or are seriously injured. Major mine hazards include roof falls, rock bursts, and fires and

The process of coal benefiticiation is required to reduce the impurities in the coal,what are the obstacles and problems that come with coal beneficiation?.
#0183;#32;History of coal Beneficiation . The technological progress in coal preparation from a global perspective is indicated in Figure (a). The history of establishment of coal washeries in India is illustrated in Figure (b), in which the period is divided into landmarks of

The heat affected coal is very difficult to beneficiate in flotation cells as the surface properties are similar to a coal which has been oxidised. The rocks found in the coal seam are fine to crystalline and green to dark green and gray. Yellowish chill, flow banding and flow laminations are common. Some dykes have spinifex textures.
PROBLEMS IN EXISTING COAL BENEFICIATION PLANTS Increased production from Lower Seams. Enhanced supplies from mechanical opencast mine consisting considerable proportions of free dirt, boulders and other lumpy extraneous materials. Increased proportions of fines below mm in the feed Change in the seam wise composition in feed with the inclusion

stand alone thermal plant or captive thermal plant of installed capacity of 100 MW or above located between km from pit head 1st January, 2015 shall be supplied with and use raw coal or blended coal or beneficiated coal less that 34% ash on quarterly basis. The above specified distance has further been reduced to 500749 km
Coal beneficiation plant not only helps improving performance of power plants,but also the reduces transportation cost. The most import is that it reduce the adverse effects on the environment. Coal beneficiation plant could be divided into two parts:coal crushing beneficiation and coal grinding beneficiation.
Operational problems. A coal preparation plant even though very well designed, cannot give good results unless proper care is taken in running it with a wellplanned operation and management schedule. The operational problems can be divided into two categories one due to designed defects and the other due to defective operation.
