尼尔森选矿机在大型镍铜矿半自磨回路中的应用
|
摘要
金川镍铜矿石中富含贵金属矿物,在常规磨矿流程中进行了贵金属尼尔森重选回收的工业试验。依据试验情况和贵金属矿物的性质,设计了尼尔森选矿机在半自磨回路中的应用流程,并在金川大型镍铜矿半自磨回路中成功应用,在原矿贵金属品位Au 0.11g/t、Pt 0.19g/t的情况下,得到了品位Au 60.95g/t、Pt 218g/t,回收率Au 29.92%,Pt 61.96%的贵金属精矿,取得了良好的选别指标。
The Jinchuan Ni-Cu ore is rich in precious metal minerals,and an industrial test for the recovery of precious metals using Knelson is carried out in a conventional grinding process.According to the test conditions and the nature of precious metal minerals,the application process of Kelson concentrator was designed and successfully applied in the SAG circuit of Jinchuan large-scale Ni-Cu concentrator.In the case of precious ore grades of Au 0.11 g/t and Pt 0.19 g/t,precious metal concentrates with grades of Au60.95 g/t,Pt 218 g/t,recovery of Au 29.92%and Pt 61.96% were obtained.And a good selection index was obtained.
