摘要:

为更好地查清某铜矿石选别过程中铜流失的主要原因,借助先进的扫描电镜、能谱仪及BPMA分析系统等分析手段,测定铜尾矿中的矿物组成、解离度、连生程度、嵌布关系等工艺矿物学参数。结果表明:铜尾矿中铜矿物主要为黄铜矿和铜蓝,铜分布率分别为89.01 %和10.99 %;铜矿物粒度较细,黄铜矿和铜蓝粒径均小于38 μm,呈微细粒分布;黄铜矿单体解离度较低,与脉石矿物连生较为密切,铜蓝多以单体形式存在。工艺矿物学研究结果可为该铜矿石生产工艺优化改造,提高铜回收率提供理论依据。

Abstract:

In order to find out the main causes of copper loss in copper ore dressing process,the mineral composition,dissociation degree,continuity degree and embedding state of minerals in copper tailings are researched by means of advanced scanning electron microscopy,energy spectrum and BPMA analysis system.The results show that the copper minerals in the copper tailings are mostly chalcopyrite and covellite,and the copper distribution rates are 89.01 % and 10.99 % respectively; the grain of the copper minerals is tiny in microfine particles with both the grain size smaller than 38 μm;the monomer dissociation degree is low for chalcopyrite and it is closely associated with gangue minerals while covellite is mostly in monomer form.The process mineralogy research results provides theoretical basis for the optimization of copper ore dressing process and the improvement of recovery rate.
