Coal drying. Coal preparation plants that employ fine coal cleaning by froth flotation can produce an unacceptable amount of moisture in the product. Thermal drying, in which the wet coal is dried in the hot gas generated by a coalor gasfired burner, is used in some plants to reduce the moisture content. Refuse and tailings management.

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.
