07/10/2019 · Three forms of sulfur occur in coal: (1) organic, (2) inorganic, and (3) elemental. Understanding the forms of sulfur in a coal is important because coal preparation can reduce the inorganic (pyritic and sulfate) sulfur in coal, but not the organically bound sulfur in coal. Sulfur is distributed in several different forms and scales in coal.
