Fine cyanide tailing particles have slow settling speed and it is difficult for de-watering.Therefore,it is needed to use flocculant to improve the settlement characteristics of this kind of tailings.In this paper,the optimum dosage of cationic flocculant HLM and nonionic flocculant PAM are determined by the sedimentation and turbidity removal experiment of cyanide tailings suspensions,the average particle size of which are 30 μm,14 μm,3 μm respectively.In addition,the flocculation performance of two flocculants for different particle size of suspensions is compared.The results show that the flocculation effect of HLM is better than PAM for the three different particle size distribution of suspension.In addition,the smaller the particle size is,the more obvious the flocculation advantage of cationic flocculant is.
