Coal washing – The process of separating undesirable materials from coal based on differences in densities. Pyritic sulfur, or sulfur combined with iron, is heavier and sinks in water; coal is lighter and floats. Coke – A hard, dry carbon substance produced by heating coal to a very high temperature in the absence of air.
