TECHNOLOGIES IN USE FOR THE PROCESSING OF FINE COAL
2016年10月22日 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 coal.
