Coal preparation is a stage in the coal supply chain that follows mining but precedes shipment to the final end user. For many operations, run-of-mine coal consists of a composite mixture of carboniferous material and various non-coal impurities, such as rock, shale, clay, and water. Coal preparation, also denoted washing, cleaning, …
