Gravity Separation Of Coal

Gravity Separation An Overview Sciencedirect Topics

Most coal cleaning processes that are used to remove inorganic impurities from coal are based on the gravity separation of the coal from its associated gangue. ROM coal consists of some proportion of both coal and shale particles, already sufficiently liberated, together with coal particles with inclusions of gangue i.e., bands of shale.
