| Abstract: |
| The pH value of wastewater from lead-zinc mixed ore processing is high. It contains a lot of suspended solids, inorganic metal ions and residual mineral processing reagents. The wastewater flow is large, the water quality and quantity are unstable, and it is difficult to treat. In this study, the "adjustment-coagulation-sedimentation-ozone oxidation" process was used to treat the mixed ore dressing wastewater. After the whole process reuse test (coagulant selection comparison test, ozone removal beneficiation agent test), COD in wastewater can be reduced by more than 50%, the residual terpineol oil in the wastewater will not enter the beneficiation process directly，the wastewater indicators meet the requirements of the whole process of beneficiation. |
