铜陵某铜矿尾矿综合回收试验研究

Study on Comprehensive Recovery Process of Copper Tailings in Tongling

对铜陵某铜尾矿选矿综合回收进行了试验研究。在工艺矿物学研究的基础上,采用尾矿预先分级-粗粒磨矿-浮选-磁选工艺流程,可得到铜精矿铜品位为9.5%,回收率为33.7%,铜精矿含金4.70g/t、银158.4g/t,铁精矿铁品位66.22%、回收率16.85%、含硫0.26%。使尾矿资源得到充分利用,企业的可持续发展状况也将得以改善。

Chenying-Lanheyu district in Liaoning Benxi is located in the middle of Taizihe-Hunjiang aula cogen. The metamorphic hydrothermal and skarn type copper polymetallic deposits that are related to the Cambrian and late Yanshan intrusive rocks are widely distributed. The mineral resources are rich in the area. Through our analysis of the metallogenic geological background and physical and chemical exploration results, it is considered that this area has great potential for prospecting, and the district of the mining and geochemical anomalies have been found to be the first choice for the next work.
