Coal processing involves crushing, screening and beneficiation. Processing is where coal is converted from runofmine (ROM) coal to a product that meets the customer's requirements. Mined coal can include lumps. Crushing to a manageable size is required. Coal crushing can include a two stage process, dependent on deposit size.

How coal is formed. Coal is formed when dead plant matter submerged in swamp environments is subjected to the geological forces of heat and pressure over hundreds of millions of years. Over time, the plant matter transforms from moist, lowcarbon peat, to coal, an energy and carbondense black or brownishblack sedimentary rock.

The carbonbased matter is composed of five main elements: carbon, hydrogen, oxygen, nitrogen and sulfur. You can think of coal's formation process as a progression from biomass (newly dead plant matter) to charcoal (almost pure carbon). Over time, the oxygen and some hydrogen are gradually removed, leaving more and more carbon behind.
