materials for coal processing

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 located 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.
