| Abstract: |
| In view of the problem that the turbidity and suspended solids produced by the concentrating wastewater containing ultrafine mineral particles and residual concentrating agents in a tungsten-molybdenum concentrator have a high impact on its direct reuse, the water quality of the concentrating wastewater in the concentrator is investigated first, the water quality characteristics are clarified, and then the exploratory test of coagulation and sedimentation reagents is carried out. The BK-A coagulant has better sedimentation performance and then the field coagulation sedimentation optimization tests was carried out. The experimental results show that the optimum reaction conditions of BK-A coagulant are: sedimentation pH 9-10, BK-A dosage 20-25 mL/L, PAM dosage 6 mL/L. The turbidity and suspended solids of the treated tailings pond wastewater can basically meet the water quality index of clean water, and the silicate ion in the tailings pond wastewater can be stably reduced to about 100 mg/L. |
