shown in developing methods for preparing super—clean
coal containing less than 2% ash and 0.5% sulfur. New
techniques for recovering fine coal, such as
micro—bubble flotation, can achieve the desired result
provided mineral matter is sufficiently liberated. To
achieve sufficient liberation, however, it is often
necessary to grind to a mean particle size finer than
10 microns. Since conventional ball mills are highly
inefficient in this fine size range, the stirred ball
mill has been proposed as a more suitable means for
