Abstract

A process and apparatus for treating coal to produce micron-size coal particles having high surface reactivity and a low level of ash-forming impurities. The process involves grinding the coal in a substantially air tight fluid energy attrition mill to form a hydrophobic coal-fraction and a hydrophilic impurities-fraction, and separating the fractions by virtue of the impurities-fraction's affinity for water.
