Abstract：According to the property analysis of coal slime from Shuilian mine, the slime is low metamorphic, easily oxidized and highly slimed, which would decrease the flotability. The inorganic electrolyte was added into the flotation process to change the surface potentional of the oxidized coal slime, reduce the effect of surface oxidation to product quality and increase the yield and recovery of flotation concentrate. The result shows that, different types of inorganic electrolyte can all promote the coal slime flotation, while the effect of FeCl3 is the most obvious. At the dosage of 16mol/m3 FeCl3 , the optimum flotation result was achieved, with the coal yield and recovery of combustibles increased by 7. 33% and 10. 84%.
