| 摘 要： | 通过对金川铜镍矿某矿区正在试产的贫矿石现场流程的精矿、尾矿样品的工艺矿物学研究发现，主要存在的问题是精矿Ni、Cu品位低，MgO含量高。其主要原因是滑石易浮，大量在精矿中富集造成的。因此，要提高铜镍品位，降低精矿中MgO的含量，适当提高铜镍的回收率，最直接有效的方式是降低精矿中滑石的含量。 |
| 关 键 词： | 金川；铜镍贫矿石；工艺矿物学；提镍降镁；滑石 |

| Abstract: | Based on the precess mineralogy research of the concentrate and tailing samples from mineral processing of one mine of Jinchun copper-nickel deposit, it's showed that the main problem lies in the low-grade of Ni,Cu and high content of MgO, which caused by the considerable enrichment of the easy-to-float talc in the concentrates.Thus, reducing the talc content in the concentrates is the most effective and direct way to improve the Cu-Ni grade,reduce the Mgo content in the concentrates and properly increase the recovery rate of copper and nickel. |
| Keywords: | Jinchuan copper-nickel lean ore mineralogy improve the content of Nickel and reduce the content of magnesium talc |
