Coal Beneficiation Technology 2007 Initiatives, Policies
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: Dry-deshaling: Non-coal or shaly-coal is removed without using any liquid media.

Beneficiation Wikipedia
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 (ore concentrate) and a waste stream ().There are many different types of beneficiation, with each step furthering the concentration of the original ore.
