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。 A nickel-copper mine was introduced. In industrial tests, the properties of the selected materials were improved in the grinding process, thereby improving the sorting index and forming a new process combining grinding and selection to improve the recovery of nickel and copper and reduce the content of magnesium oxide in the concentrate. This new process is different from the traditional process of increasing recovery and magnesium reduction, but the effect is significantly better than the traditional process.
