Gravity Separation Method Of Coal Washing

Coal Cleaning - an overview ScienceDirect Topics

The process of cleaning coal is a wet one, using large quantities of water (i.e., thousands of gallons per minute). As a result, vast quantities of dirty (fine rock-laden) 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.
