The process of cleaning coal is a wet one, using large quantities of water (, thousands of gallons per minute). As a result, vast quantities of dirty (fine rockladen) water are produced. Beneficiation processes require clean water. Consequently, dirty water is processed, solids removed, and clean water recycled for further use in the plant.
