铜镍硫化物矿石中镍黄铁矿单矿物的分离方法研究

Research on the Method for Separating Pentlandite from Cu-Ni Sulphide Ore

在保证镍黄铁矿单矿物测试粒度及物化性质不被破坏的前提下,通过对三个产地,四件试样的综合分析及系统分离试验,研究出用重选-强磁选-浮选-电磁选等联合分离流程提纯镍黄铁矿的全过程,分离纯度达到90%以上。本文中分别叙述了镍黄铁矿与磁黄铁矿、镍黄铁矿与黄铜矿、镍黄铁矿与黄铁矿的分离方法。

On the condition of the test granularity of single grain pentlandite and its physical-chemical characters not destroyed,through the analyses and the system separation experiment of the 4 test specimen form three areas,the authors have gotten whole process of pentlandite separation with gravity separation-strong magnetic separation-flotation process-electricity magnetic separation.The pureness is above 90%.
