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.

Once unloaded, the coal is then pulverized into a fine powder by a large grinder. This ensures nearly complete burning of the coal in order to maximize the heat given off and to minimize pollutants. The pulverized coal is then input to a boiler, where combustion occurs and the coal provides heat to the power plant.
