Beneficiation of coal (separation of ash minerals from coal) is generally achieved using the waterbased processes. Most of the preparation plants utilizes gravitybased processes, such as jigs, heavy media vessels, cyclones, spirals, etc., for particles down to a size of 28 mesh ( mm). The finer size (minus 6 mm) is beneficiated either by ...
