How Coal Works

Dec 15, 2017If 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.
