| 摘 要： | 金川硫化铜镍矿作为超大型铜镍矿床,资源丰富,除主要镍外,且有铜、钴及铂族金属元素伴生。随着常年开采,矿石贫、细、杂的情况也愈发明显,由于采用选冶联合的铜镍分离方式,且以蛇纹石为主要含硅酸盐脉石易浮情况下,随着原矿的不断贫化,扔需要保证MgO的合格,这就给选矿工作带来非常大的难度和挑战。金川铜镍硫化矿浮选降镁问题作为世界性难题,得到广泛关注,针对其降镁问题的选矿药剂也不断在开发当中。但在实际生产中,往往结合现场生产情况和实际成本,有些药剂对企业效益提升往往不大,本文总结阐述了金川公司往年针对铜镍硫化矿降镁药剂的技术情况,以及其他含氧化镁矿物降镁的选矿药剂的发展情况,望能给广大选矿工作者在铜镍硫化矿降镁方面提供技术参考。

| Abstract: | As a super-large copper-nickel deposit, Jinchuan copper-nickel sulfide ore is rich in resources, in addition to the main nickel, and accompanied by copper, cobalt and platinum group metal elements. With perennial mining, the situation of ore poverty, fine and miscellaneous is becoming more and more obvious, due to the use of copper-nickel separation method combined with metallurgy, and serpentine as the main silicate-containing gangue easy to float, with the continuous depletion of raw ore, throwing needs to ensure the qualification of MgO, which brings great difficulty and challenge to the beneficiation work. As a worldwide problem, the problem of flotation magnesium reduction of Jinchuan copper-nickel sulfide ore has received widespread attention, and the beneficiation agent for its magnesium reduction problem is also constantly being developed. But in the actual production, often combined with the on-site production and actual cost, some agents to the enterprise efficiency improvement is often not large, this paper summarizes and expounds the technical situation of Jinchuan company in previous years for copper-nickel sulfide ore magnesium lowering agent, and the development of other magnesium oxide mineral-containing magnesium processing agent, is expected to provide technical reference for the majority of mineral processing workers in copper-nickel sulfide ore magnesium reduction. |
