Integrally, large numbers of ...

Processes and arrangements that provide for the separation of pyrite from coal in a fluidized bed. The processes provide for more efficient and complete stratification of the bed materials in a vertical direction, so that the very top layer of the fluidized ved is coal having a reduced pyrite content. The process includes feeding the coal to be cleaned on top of a layer of magnetite.
