LIGNITE COMPLEX PROCESSING LINE AND METHOD Russian patent published in 2015 - IPC C10B53/00 C10L9/00 

FIELD: mining.

SUBSTANCE: inventions can be used in lignite and high ash coal processing. Lignite processing line comprises super high frequency heating reactor 2 connected by its gaseous product outlet with the cooler 4, dispersing device 9 and pump 8. Super high frequency heating reactor 2 is composed by a coal distillation device and connected by the solids outlet with water tank 7 being communicated, in its turn, with the said dispersing device 9 connected with at least one settling-separating column 11. Processing line implements the method of lignite processing including a crushed lignite distillation with recovery of combustible gas. Coal distillation is executed at super high frequency heating reactor 2. Combustible gas recovery is performed after its separation from the sublimates at the cooler 4. Said sublimates are settled at the cooler 4 and used as the metal concentrate. After coal distillation, the coal is mixed with water and dispersed for dispersed mix to be separated to live coal and mineral fraction.

EFFECT: higher yield of lignite with gas and sublimate extraction and dressing of live coal.
