Abstract : A method is described for reducing the amount of sulfur present in coal which comprises grinding the coal to less than 100 microns, physically separating the fine coal rich fraction from the coarse pyrite rich coal fraction, diluting the coarse pyrite rich coal fraction with a liquid hydrocarbon carrier and then separating the high pyrite coal from the low coarse pyrite coal by passing the particles through a magnetic separtor.
