What Is Coal Preparation Energy.gov

What Is Coal Preparation? • Coal preparation is the removal of undesirable material from the Run-of-Mine (ROM) coal by employing separation processes which are able to differentiate between the physical and surface properties of the coal and the impurities. Through coal preparation, a uniform product is achieved.

How Dry Coal Processing Work Coal Processing Methods

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.
