吉林省某铜矿选矿的实验研究

Experimental study on beneficiation of copper mine in Jilin Province

为探索最佳工艺条件实验方案,采用原矿多元素化验、原矿物相化验方法分析该铜矿的化学性质和元素构成,运用磨矿细度、工艺条件、铜与硫元素分离实验,获得最佳的浮选工艺条件。结果表明,该矿石磨矿所需细度较高,采用新型药剂HGT可以实现铜与硫的有效分离。通过浮选流程实验,证明了铜精矿与硫精矿选矿指标非常理想,为该类矿石的可选性研究和工业生产提供了基础性依据。

This paper is an attempt to explore the experimental scheme of the optimum technological conditions.The study entails analyzing final beneficiation process,the chemical properties and element composition of the copper deposit by means of multi-element chemical test and primary mineral phase test;and exploring the optimum flotation conditions by grinding fineness experiment,technological condition experiment and separation experiment of copper and sulfur element.The results show that given that the ore needs higher fineness for grinding,using the new reagent HGT could enable the effective separation of copper and sulfur.The scheme and method for the experiment are scientific and reasonable.The final flotation process experiment points to very ideal mineral processing index of copper concentrate and sulfur concentrate.The study could inform the study of separability and industrial producing of this kind of ore.
