Abstract：In order to utilize strong brine from coal chemical industry comprehensively,slime water free settling experiments were conducted using strong brine and the Yellow River water.By simulating flotation technological conditions, the coal slime was separated by strong brine,PAM and PFS.The results showed that,the coal slime was easy to mud,so it was difficult to settle.A certain concentration of strong brine was helpful to the free settling of coal slime.The mass fraction of residual suspended solids could be controlled within 21%.The set-tlement effects of strong brine which was diluted with two times water was the best,the removal rate of suspended solids was above 85%. The combined of PAM and PFS could obtain a better effect,and the concentration of the two was 3 mL/L and 0.5 mL/L.
