摘　　要：金川铜镍硫化矿作为超大型铜镍矿床,资源丰富,除主要元素镍外,还有铜、钴及铂族金属元素伴生。随着常年开采,金川铜镍硫化矿矿石贫、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,在以易浮的蛇纹石为主要含硅酸盐脉石情况下,随着原矿的不断贫化,仍需要保证MgO的合格,这为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,由此得到广泛关注,针对其降镁问题的选矿药剂也在不断开发中。但在实际生产过程中,往往需要结合现场生产情况和实际生产成本,有些药剂对企业效益提升往往不大。总结阐述了金川公司往年针对铜镍硫化矿降镁药剂的研究进展,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。As a super-large copper-nickel deposit,Jinchuan copper-nickel sulfide ore is rich in resources.In addition to nickel as the main element,the accompanying valuable metals include copper,cobalt and platinum group elements.With perennial mining,the situation of ore dilution,sliming and complexity in composition 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 being easy to float,with the continuous depletion of raw ore,the growing needs to meet the qualification requirement for MgO-content have brought great difficulty and challenge to the beneficiation work.As a worldwide problem,the problem of flotation magnesium reduction by flotation 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 in developing magnesium-lowering agent for the copper-nickel sulfide ore flotation,and the development of such agent for other magnesium-oxide containing ores providing technical reference for the majority of mineral processing workers in copper-nickel sulfide ore magnesium reduction.
