Heavy Media Separation

The heavy media process is usually used for treatment of coarse coal above 9.5 mm in size. Finer coal below 9.5 mm cannot be cleaned economically in heavy medium. The settling velocities of the fine material are very low, and consequently the time required to separate the lighter coal from the heavy becomes excessive.
