The source of nearly 50 pct of the sulfur content of an average bituminous coal used by an electric utility is pyrite (FeS2); pyrite is a component that is not chemically bound to the coal and, therefore, can be removed by physical separation methods. Removing 50 to 70 pct of the pyrite would accomplish only a 25- to 35-pct reduction in SO2 ...
