Coal Mining and Processing Energy Trends Insider

Processing the Coal. After coal comes out of the ground, it typically goes on a conveyor belt to a preparation plant that is loed at the mining site. The plant cleans and processes coal to remove dirt, rock, ash, sulfur, and other unwanted materials, increasing the heating value of the coal. Source: Energy Information Administration

Coal Beneficiation Process Diagram

Many breakers and washeries efficiently handle the coarser sizes, but waste the coal fines. This problem is assuming major importance due to the increase in the amount of coal fines being produced by the mechanization of coal mining. Flotation offers a very satisfactory lowcost method for recovering a fine, low ash, clean coal product at a profit.
