Coal is an important fossil fuel and is used as a major source of energy in power plants and blast furnaces.But, Indian coals contain a large amount of impurities, particularly ash forming mineral matter, which interfere with proper combustion of coal and decreases its calorific value. Industrial uses demand coal with minimum ash content so that it can be efficiently used in metallurgical, or, power plants. This paper reviews the removal of ash-forming minerals of coal using chemical techniques and also the extraction of coal by the use of various solvents. Solvents
