Abstract: Following an account of the background of the application of the coarse coal recovery process,the paper elaborates on the performances of the conventional coarse coal separation processes. Then the approaches for treating the coarse slime with different size ranges are proposed,i. e. separation of sized seed and recovery of slime in a stepped manner. At the end,the paper presents a summation of the scope of applicability of each kind of the coarse slime separation and recovery equipment in conventional use.The study is of certain reference value for the increase of yield of combined clean coal product and reduction of medium consumption.
