Coal cleaning process - Exxon Research & Engineering Co.

Because of the wide variance in the original composition of raw coal, the conventional method of cleaning by crushing the coal and then washing the various size fractions to separate the low density, clean particles from the higher density dirty particles will produce a clean coal of widely varying composition.

11.10 Coal Cleaning - US EPA

Coal cleaning processes are categorized as either physical cleaning or chemical cleaning. Physical coal cleaning processes, the mechanical separation of coal from its contaminants using differences in density, are by far the major processes in use today. Chemical coal cleaning processes are currently being developed, but their performance and cost are undetermined at this time.

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.

Coal Cleaning - an overview | ScienceDirect Topics

Basic physical coal cleaning techniques have been commercial for over 50 years. The cleaning of coal takes place in water, in a dense medium, or in a dry medium. Physical cleaning processes are based on either the specific gravity or the surface property differences between the coal and its impurities.

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.
