个旧锡多金属矿尾矿物质组成特征研究

Research on Major Elements and Mineral Composition of Tailings on Tin-Polymetallic Mine in Gejiu Yunnan province

根据常量元素分析结果,对个旧地区锡多金属矿尾矿进行了岩石化学分类;针对该地区尾矿中铁含量高的情况,通过人工重砂分析查明了铁的赋存状态,并据此对含铁矿物的可利用性进行了评估;采用X射线粉晶衍射分析手段研究了该地区尾矿的矿物组成,指出云母和萤石也是该地区尾矿中应考虑予以回收的组分。

According to the major elements analysis, the classification of tailings in Gejiu tin-polymetallic mine was made by the petroehemistry. For high iron content in tailings, the occurrence of iron was known by the artificial heavy min- erals analysis. Based on this, Iron resouree＇s availability in the tailings was evaluated. By adopting the X-ray diffraction, the paper investigated the mineral composition of tailings in this area. It was pointed out that Mica and fluorite are also the potential recoverable minerals in this tailing.
