    Abstract: In order to strengthen the thin coal slime settlement, and improve the efficiency of solid-liquid separation, in this paper, as the research object of Wuyang coal slime, carried out the studies on the effect of flocculation and settling with different inorganic electrolytes, and using electrophoresis analyzer, image analyzer and FTIR, characterized inorganic electrolytes effect on zeta potential of coal particles, floc size and surface functional groups. The results showed that: the effect of flocculation and falling, with CaCl 2 and non-ionic PAM, is better than several other inorganic electrolytes. When the amount of non-ionic PAM is 3ml, CaCl2 best dosage is 4ml, corresponding to the initial falling speed is 24.49cm/min, supernatant turbidity is 22NTU. It has certain effect to the zeta potential of coal particles, floc size and the functional groups of coal surface after adding inorganic electrolytes. ? (2011) Trans Tech Publications, Switzerland.
