Understanding coal quality and the critical importance
Coal cleaning technologies are, for the most part, water or media based. The coal gets wet; the water needs to be removed and reused in the preparation plant. Coal dewatering technologies, an inherent part of beneficiation, remove the surface moisture based on dewatering forces, such as vacuum, gravity, centrifugal forces, pressure, etc.

(PDF) Beneficiation of Coals: A Review
Beneficiation of Coals: A Review. Coal is an important fossil fuel and is used as a major source of energy in power plants and blast furnaces. But, Indian coals contain a large amount of impurities, particularly ash forming mineral matter, which interfere with proper combustion of coal and decreases its calorific value.

TECHNOLOGIES IN USE FOR THE PROCESSING OF FINE COAL
Abstract. Coal is the most abundant fossil fuel and about 42 % of the world electricity is generated through coal fired power stations. However, mechanized mining has led to an increase in the quantity of fine coal production. The value of the fine coal necessitated the selection of the correct equipment for the gravity beneficiation of this …

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.

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.
