Coal Mining

Coal Mining

In the separation step, the liberated particles are classified into the appropriate groups of coal, impurities, and middlings. Since impurities are generally heavier than middlings and middlings heavier than coal, the methods most commonly used to separate the input stream into the three product streams are based on gravity concentration.
