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.

KENTUCKY (7/23/18) — The largest independent oil trader and a giant of the mining industry have joined with a U. K. Startup developing a process to pulverize coal, remove impurities and pollutants

Processing and Transporting 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. A "prep" plant cleans and processes coal to remove dirt, rock, ash, sulfur, and other impurities.

If coal is high in sulfur or other impurities, it is washed with a water or chemical bath, removing up to 40 percent of inorganic sulfur in the coal. Not all coal is prepared using the same process. High-sulfur coal commonly undergoes washing to meet environmental regulations, while low-sulfur coal is often crushed and resized without being washed.

Global steel production is dependent on coal. 74% of the steel produced today uses coal. Metallurgical coal – or coking coal – is a vital ingredient in the steel making process. World crude steel production was 1.6 billion tonnes in 2017.

Coal is a flammable black hard rock used as a solid fossil fuel. It is mainly made up of 65-95% carbon and also contains hydrogen, sulphur, oxygen and nitrogen . It is a sedimentary rock formed from peat, by the pressure of rocks laid down later on top.

Improving the Properties of Mined Coal. Kentucky coal is improved by the partial removal of the impurities—sulfur and ash.
