Coal, Kentucky Geological Survey, University of Kentucky

The specific gravity of coal is important during coal cleaning because many of the common mineral impurities in coal have much higher specific gravity (density) than coal. For example, the specific gravity of pyrite (fool's gold), a common impurity in coal, and the main source of sulfur in coal, is 4.9 to 5.2.
