How Coal Works Union of Concerned ScientistsWhat Is Coal Preparation Energy
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 washedWhat Is Coal Preparation • Coal preparation is the removal of undesirable material from the Run of Mine ROM coal by employing separation processes which are able to differentiate between the physical and surface properties of the coal and the impuriti Through coal preparation a
