Usage: can be used as an energy raw material for generating electricity. To improve the energy properties of coal, it is recommended to use dry enrichment methods using two or three- product pneumatic separators with a dust collection system. Preparatory operations before pneumoseparation - classification by machine classes and drying of coal
