摘　　要：以黄平麦巴铝土矿以及周围相对汇水单元为研究区,通过分析酸性淋溶水中铜、砷、镉、铬及铁、硫酸根、铝等元素离子的来源,确定污染源、污染介子、污染程度、污染迁移衰减程度等,得出露采型铝土矿山酸性淋溶水的形成机理。Focusing on the Maiba bauxite mine in Huangping and its surrounding catchment areas,this study analyzed the sources of copper,arsenic,cadmium,chromium,iron,sulfate,aluminum,and other ions in acidic leachate to identify pollution sources,mediators,pollution levels,and the extent of pollution migration and attenuation.The observations show the mechanism behind the formation of acidic leachate in open-pit bauxite mines.
