摘要:

以西部干旱区金矿历史遗留堆浸氰化尾渣为研究对象,在充分分析矿区气候环境、水文地质、堆浸氰化尾渣污染特征的基础上,选择利用原位关闭作业来验证对堆浸氰化尾渣中重金属等污染物的管控效果。详细介绍了原位封存阻隔方案,管控监测及辅助方案等,工程实施后环境污染风险得到有效控制,周边环境得到明显改善,达到预期工程目标。该管控技术可为同类型金矿堆浸氰化尾渣的污染控制提供借鉴参考。

Abstract:

In the case study of the pollution control over the heap leaching cyanide residue left by historical gold mines in arid areas of western China.Based on a thorough analysis of climate,hydrogeology,and the characteristics of heap leaching cyanide residue pollutants,in-situ closure operation is employed to verify the pollution control effect over the pollutant such as heavy metals in heap leaching cyanide residue.The paper in detail describes the in-situ sealing and isolation scheme,control and monitoring scheme,and auxiliary schemes.After implementation,the environmental pollution risks are effectively controlled,and the peripheral environment is evidently improved,achieving anticipated engineering goals.The control technology can provide references for the pollution control of heap leaching cyanide residue generated from similar gold mines.
