磨选结合提高镍铜回收率及降低氧化镁含量新工艺的应用研究

Study to Application of Combination of Grinding and Separating Process on Increasing the Collecting Ratio of Nickel-Copper andDecreasing Magnesia Content in Concentrate

介绍了某镍铜矿,在工业试验中,在磨矿中改善入选物料特性,进而提高选别指标,形成了一套磨选结合提高镍铜回收率及降低精矿氧化镁含量的新工艺,此套新工艺不同于以往提高回收率及降镁的传统工艺,而效果却显著优于过去的传统工艺。

In certain nickel-copper mine, the characteristic of feeding material improved in the industrial experiment so as to enhance the separating index, a new set of technique combined grinding and separating process for increasing the collecting ratio of nickel-copper and decreasing magnesia content in concentrate was formed. The technique is not the same as the traditional technique for increasing the collecting ratio and decreasing magnesia content, the effect is superior to previous traditional technique.[ Descriptors ] Combination of grinding and separating process Increasing the collecting ratio Decreasing magnesia content Industrial experiment
