| Abstract: |
| Fine solids in the tailing water of Xinhua Molybdenum Mine always maintain suspended and unsinkable due to high concentration of sodium silicate. In this study, the residue turbidity and settling rate of the wastewater with different coagulants are examined, using H2SO4and CaO as the pH regulators, PAC,PAFCS and PAM as the flocculants and CaCIE and MgCIE as coagulation aids. The results show that the effects are optimum with the combination of 600g/t CaO, 20g/t PAM and 200 g/t CaCl2. |
