| Abstract: | A brief discuss on the negative effect of fine slime with particle size less than 0.045 mm on floatation and clarification was introduces in this paper.And the result of secondary mudding experiments of recycled coal slime were compared and analyzed.It was presented that the partial recycle in coal slime processing should be avoided in the flow process of coal slime water in coal preparation plant. |

| Keywords: | fine slime secondary mudding diminution rate of average particle size R-R equation of particle size distribution partial recycle |
