• Process for beneficiating and stabilizing coal/oil/water

    The coal may first be coarsely ground and water is added and initial separation of contaminants with the water is carried out by froth flotation although other conventional separation methods may be used. The "clean" coal/water slurry is then subjected to a grinding operation to grind the coal to between 100 to 300 mesh.

  • Advanced physical coal cleaning to comply with CORE

    Therefore to remove the pyrite using physical coal cleaning techniques the pyrite must be liberated by grinding the coal to ultrafine particle sizes. Fortunately the coals being fed to pulverized coal boilers (PCB) are already ground to a very fine size i.e. 70 passing 200 mesh.
