微细粒氧化铜矿物难选原因探讨

Discussion on difficult-to-float reasons in the flotation of fine-particle copper oxide minerals

微细粒嵌布的氧化铜矿物资源越来越多,由于其特殊的性质,非常难选。本文通过对现场统计数据的分析及不同粒级孔雀石纯矿物实验结果的对比,揭示了微细粒氧化铜矿物难选的原因,为微细粒难选氧化铜矿物的选矿回收方法的研究,提供了有益的借鉴。

Fine-grain disseminated copper oxide minerals are very difficult to float in production due to its special nature.Hallimond tube flotation tests were conducted using malachite pure mineral with different size fractions in order to find out the difficult-to-float reasons.The results obtained showed that the difficult-to-float reason of copper oxide minerals with fine size fraction of-10 microns was due to their tiny particle size coupled with tiny mass.
