A novel dry beneficiation process for coal
Dry coal beneficiation is an effective technique to realize coal separation and upgradation, as it does not consume water, has a low cost and is pollution-free. In this study, an air dense medium fluidized bed (ADMFB) and FGX separator were arranged in series to achieve 100–0 mm coal size dry separation. Raw coal (100–50 mm and 50–0 …

Ultrasonic-assisted coal beneficiation: A review
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.
