The objective of proximate analysis indicates the percentage by weight of the Fixed Carbon, Volatiles, Ash, and Moisture Content in coal. The amounts of fixed carbon and volatile combustible matter directly contribute to the heating value of coal.
Coal preparation is the process where raw coal from mine is cleaned using different physical processes, with or without any chemical reagents, to get a product which could be sold in the market or can be used for different purposes as coke making or power generation (Albrecht, 1980). The reasons for cleaning coal are to: 1  remove inorganic material (ash) thus reducing ash handling in coal plants. 2  increase the heating value of coal. 3  reduce the transportation cost per unit weight of coal. 4  meet customers' specifications.
