Coal Cleaning an overview | ScienceDirect Topics

Coal cleaning is an option for removing mercury from the coal prior to utilization. Of the approximately 1 billion short tons of coal mined each year in the United States, about 600 to 650 million short tons are processed to some degree (National Research Council, 2002; Fiscor, 2015).

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.

How Dry Coal Processing Work-Coal Processing Methods

Three product streams, i.e., clean (deshaled) product, middlings and tailing streams are generated during the separation process. An air collection system is employed to clean the recycled air and to remove the dust from air being emitted into the atmosphere. This makes FGX separators cleaner than other coal processing methods.

The quality of clean product of the FGX circuit at the Eagle River Plant can be sold directly, which generates significant economic benefits

Coal Washing | Encyclopedia

Coal washing is accomplished by one of two major processes, by density separationor by froth flotation. Both processes depend on the fact that the particles of which a coal sample are made have different densities. When water, for example, is added to the sample, particles sink to various depths depending on their densities.
