| Abstract: | In order to improve the quality of wastewater from tailings, settling performance of tailings from a copper slag concentrator was studied. Based on the comparison of settling performances of tailings with different size distribution, the influence of polymer flocculants of different type and dosage on settling effects was discussed. Results show that the sedimentation velocity of fine-grained tailings is substantially improved, and the supernatant turbidity is reduced by using polymer flocculants, among which cationic-type polyacrylamides performs better than both non-ionic and anionic ones, with an appropriate dosage of 6 g/m3. |
