Coal preparation is a specialisation in the field of minerals technology. All coal contains some non-carbonaceous mineral matter both within the coal itself and added during the mining process (often unintentionally) where roof or floor is cut or breaks and mixes with the cut coal. This mineral matter affects the properties of the coal and ...
