what the process to get coal

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. Highsulfur coal commonly undergoes washing to meet environmental regulations, while lowsulfur coal is often crushed and resized without being washed.
