Magnetite Consumption In Coal Washing With Magnetic Content

Coal Washing, Magnetic Separation Processing The dense medium separation process used in most coal washing and magnetic separation plants requires a suspension of finely milled magnetite in water. Magnetite for coal washing must be of overall high purity and be devoid of contaminants, such as hematite, sulphides or other minerals.
