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.

Abstract. To produce liquid fuels from coal, either direct or indirect liquefaction routes can be used. The discussion of the former route is the subject of Chapter 6; the latter route will be discussed here. The indirect liquefaction route consists of the conversion of coal to synthesis gas (hydrogen plus carbon monoxide), and then the ...
