How Coal Works Union of Concerned Scientists

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.

Coal Simple English Wikipedia, the free encyclopedia

Coal is a hard rock which can be burned as a solid fossil fuel.It is mostly carbon but 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..
