Coal Beneficiation Coal beneficiation is a process by which the quality of raw coal is improved by either reducing the extraneous matter that gets extracted along with the mined coal or reducing the associated ash or both. Two basic processes of beneficiation: – Drydeshaling: Noncoal or shalycoal is removed without using any liquid media.
China coal preparation trends. Coal is the main energy source in China. For the purpose of increasing the efficiency of coal combustion and the reduction air pollution caused by coal combustion, and adapting to the request of coal products market, now the development of coal preparation is quickly progressing in China.

In the mining industry or extractive metallurgy, beneficiation is any process that improves (benefits) the economic value of the ore by removing the gangue minerals, which results in a higher grade product (concentrate) and a waste stream ().Examples of beneficiation processes include froth flotation and gravity separation.. Other economic uses of the term are in use.
The quantum of coal fines below 6 mm in runofmine (ROM) coal has been increasing due to progressive mechanization of mining methods which has created a substantial incentive, worldwide, to develop suitable fine coal beneficiation techniques. The majority of the efforts have been directed toward reduction in ash/sulfur contents in clean coal.
