摘要
以洛南县振兴钼业公司尾矿表生矿物为研究对象,分别使用X衍射分析方法、ICT-AES仪器以及电子显微镜对尾矿样品原生矿物组成与新生矿物的种类与含量、混合样品及尾矿坝样品重金属含量以及表生矿物的形貌特征等进行分析,得出尾矿的表生矿物针铁矿形成机理、对重金属的富集机理以及通过针铁矿对重金属的富集作用可降低重金属对周围环境的危害。
railings goethite in Zhenxing Molybdenum Company of Luonan county is selected as subject investigated. It uses X- diffraction to analyse the tailing samples＇ primary mineral Composition and neogenic mineral category and content, uses ICT - AES instrument to analyse the content of heavy metal of mixed samples and tailing dam samples, uses electron microscope to obtain the photograph and analyse surface mineral characteristic. The experimental results should conclude that the mechanism of cumulation of surface mineral of tailing（ Fe（OH）3 and the cumulation can ruduce the hazards to environment.
