【Abstract】 In view of the property of the coal produced by the mines of Kailuan Group, 3 different heavy medium separation processes are applied: the process of treating undeslimed feed with 3-product H. M. cyclone; and the process of treating deslimed feed using 2-product H. M. cyclone. The middling product magnetic tailings(MPMT) produced in the 3 processes are respectively spectively taken as the object of study. Through experimental study and optimization of processing schemes, the coarse slime fine separation and recovery process is proposed. Application of the process has led to further improvement of economic performance and competitive edge of preparation plants involved.更多还原
