Coal is a combustible black or brownishblack sedimentary rock, formed as rock strata called coal is mostly carbon with variable amounts of other elements, chiefly hydrogen, sulfur, oxygen, and nitrogen. Coal is a type of fossil fuel, formed when dead plant matter decays into peat and is converted into coal by the heat and pressure of deep burial over millions of years.

Coal preparation is the removal of undesirable material from the RunofMine (ROM) coal by employing separation processes which are able to differentiate between the physical and surface properties of the coal and the impurities. Through coal preparation, a uniform product is achieved. Washability Study

During the coal mining process, a significant amount of coal wastes is produced, including (1) mining wastes, (2) washery wastes, and (3) secondary processing wastes. Since 2017, the annual global CMWs are estimated to be 315 million tons for underground coal mining. This results in the disposal of a considerable volume of wastes at waste dumps.

Coal washing is accomplished by one of two major processes, by density separation or by froth flotation. Both processes depend on the fact that the particles of which a coal sample are made have different densities. When water, for example, is added to the sample, particles sink to various depths depending on their densities.
