Dry coal cleaning technologies include air-jigging [8-11], air-table [12-15], FGX separator [16-19], and Reflux Classifier
[20-23]. These processes provide efficient solutions to the coal dry cleaning. However, compared to wet cleaning processes, the
separation efficiency of all these dry technologies are general low in the way of industrial applications. Having a better separation
efficiency dry coal beneficiation method is a major concern, especially in the arid geological environment and prolonged cold
weather areas (many parts of Africa, Asia, Russia and certain areas of USA).
