内蒙古正南房铜矿选矿流程研究

Amelioration of Ore Dressing Flowsheet for Zhengnanfang Copper Mine in Inner Mongolia

对内蒙古正南房铜矿选矿旧流程进行了技术改造,将第二段磨矿改为精选1尾矿分级后再磨,既可防止矿石过磨,又可使精选1尾矿充分单体解离,减少了磨矿处理量,大幅度降低了生产成本,同时大大降低了操作难度,提高了各项生产技术指标,为企业和社会创造了较大经济效益。

In the technical reconstruction for the dressing process of Zhengnanfang Copper Mine in Inner Mongolia, the second stage of direct grinding was replaced by a regrinding for underflow of classified tailings from the first stage of cleaning, which can not only prevent overgrinding, but also ensure the sufficient liberation of minerals. With the reduction in the load for grinding, the production cost and the operation difficulty are significantly reduced, while the processing index is obviously improved, bringing more economic benefits to the enterprise and society.
