coal preparation,
• Coal preparation is the removal of undesirable material (ash, Sulphur, moisture)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. • Coal preparation is also called as Washing, Cleaning, Processing of Coal.

Coal cleaning process
Abstract. The LICADO LIquid CArbon DiOxide process is currently being investigated as a new technique for cleaning coal. It relies on the relative wettability of clean coal and mineral particles between liquid CO/sub 2/ and water so that when liquid CO/sub 2/ is dispersed into a coal-water slurry, it tends to form agglomerates with the clean coal particles and float them to the liquid CO/sub 2

The process of coal cleaning must be tailored to the specific characteristics of the raw coal at hand and the quality of the clean coal that can be achieved using specific equipment. Coals from different beds have different properties. Coal from the same bed, mined at different locations, may not display the same response to coal cleaning.

Heavy-media Cyclones for coal cleaning | FLSmidth
Most coal and mineral producers are familiar with cleaning methods that utilise differences in density to separate the desirable coal and mineral particles from the refuse. Heavy-media vessels have been used for decades as a standard method for coal and mineral cleaning. But just because a practice is tried, doesn’t mean it is necessarily true.

What is Clean Coal? (with pictures)
Making the mining process more clean and efficient is one way to create cleaner coal. In addition, many countries now chemically wash their coal to remove some impurities. Doing this before burning the coal ensures that the impurities will not be released into the atmosphere, although the chemicals that are cleaned off still need to be appropriately dealt with so that they do not enter the

Removal of the mineral matter (or “ash”), 3 which is largely noncombustible and may constitute up to 65 percent of the raw coal, increases the heating value of the coal on a mass basis. 4 Although some combustible material is lost as part of the cleaning process, the removal of unwanted material reduces the mass and volume of coal for a given heating value thereby reducing shipping costs

Coal Cleaning
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.
