2.4. Beneficiation methods. Beneficiation is a process where ore is reduced in size and valuable minerals are separated from the gangue minerals. Separation of valuable minerals from gangue minerals can be efficiently achieved by taking advantage of the differences in physical, surface, and magnetic properties.

Abstract. We consider here the implementation of dry coal beneficiation using air fluidized bed technology. Although the applications of the fluidized bed dry coal separator have been done successfully on an industrial scale in the past, the process has been characterized by relatively poor Ep values.

The coal slurry was pre-treated with ultrasound for different time intervals (0–180 s) at 25 kHz frequency before flotation. A higher clean coal yield of 67% was attained at a pre-treatment time of 30 s during ultrasonic-assisted flotation, while only 59% clean coal yield was attained during conventional flotation.
