Abstract: |
Yunnan Yuxi collophane beneficiation backwater was studied for the problems of the complex composition and low utilization of the backwater. Effect on the sorting index had been explored by the ions of Ca2 , Mg2 , SO42- and PO43-. It showed that all ions had a certain impact on sorting index, especially the Ca2 and Mg2 . After comparative of multiple methods, suggesting that use of "dual-alkali" PAM coagulation method can effectively remove the harmful ions, the flotation index of treatment backwater are closed to the clear water and good purifying effect was achieved. |
