As the low economic value, many available chemical and physical properties of coarse tail coal-slime used to be ignored. In this paper, coarse tail coal-slime is used as the filer medium for the treatment of circulating water in coal preparation plants. Because coarse tail coal-slime has great adsorption performance, appropriate particle size composition and mechanical strength, it is used as filter medium for pressure feeding filtering equipment in this study, to probe the feasibility of the treatment of circulating water. The results show that with using coarse tail coal-slime as filter medium in pressure feeding filtering tank, the concentration of circulating water can be reduced to below 5 g/L, it will meet the requirements; the particle size and thickness of coarse tail coal-slime have great influence on the capacity and concentration. This method does not need settlement reagents, and it makes full use of coal preparation plant waste.
