中文摘要: 本研究以我国云南省温庄尾矿库为研究对象,通过研究静态浸泡和动态淋溶条件下复合选矿药剂和重金属释放关系,探讨了尾矿残留选矿药剂对尾矿中重金属释放的影响因素,揭示了重金属释放与残留选矿药剂释放的相关性。结果表明相比单一选矿药剂,复合选矿药剂更能促进铅锌尾矿中重金属持续释放。本研究为铅锌尾矿库复合污染防治提供防治建议,为铅锌尾矿库环境污染治理及生态修复提供基础数据和理论支撑。

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.
