| Abstract: |
| Lead-zinc ore is an important mineral resource in Southwest my country. With the mining of lead-zinc mines, more and more tailings are discharged into the tailings pond and enter the external environment. Heavy metals and beneficiation agents gradually accumulate in the tailings pond, which is easy to The surrounding environment poses a threat. This study explored the pollution characteristics of heavy metals and beneficiation agents in different types of lead-zinc tailings ponds by analyzing the differences in heavy metal content, form distribution and beneficiation agents in three different types of tailings in Southwest China. The results confirmed that there are differences in the distribution of heavy metals in the sulfide ore tailings pool and the oxidation ore tailings pool. After the tailings pool is out of service, the beneficiation agent has a tendency to migrate in the deep layer. The combined pollution of heavy metals and beneficiation agents in lead-zinc tailings ponds needs to be paid attention to. This study provides a reference for pollution prevention and control of lead-zinc tailings ponds. |
