Coal Washing Encyclopedia

2021-11-24  Coal washing Coal that comes from a mine is a complex mixture of materials with a large variety of physical properties. In addition to the coal itself, pieces of rock, sand, and various minerals are contained in the mixture. Thus, before coal can be sold to consumers, it must be cleaned. The cleaning process consists of a number of steps that results in a product that is

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.
