Dry Magnetic Saperation Of Coal

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. Magnetite is reasonably durable (and therefore does not readily break down), and is chemically stable during ...

Magnetic Separator - an overview | ScienceDirect Topics

Dry HGMS processing has the advantage of a dry product although classification of the pulverised coal is required to ensure proper separation. Small particles tend to agglomerate and pass through the separator. It has been shown that individual particles of coal in the discharge of a power plant pulveriser flow freely and hence separate well only if the material below about 10 µm is removed ...

Magnetic separation of coal fly ash from Bulgarian power ...

Fly ash from three coal-burning power plants in Bulgaria: 'Maritza 3', 'Republika' and 'Rousse East' were subjected to wet low-intensity magnetic separation.
