【摘要】：针对硫化铜镍矿的浮选分离技术,详细总结了其选矿过程中铜镍矿物难于单体解离、含镁脉石矿物易于混杂、磨矿与分选过程溶液化学变化、铜镍分离中铜镍互含较高等技术难点,分别介绍了优先浮选、混合浮选、阶段磨浮、预先脱泥-浮选及浸出等工艺特点和应用,归纳了新型浮选药剂在硫化铜镍矿分选中的应用现状,分析了磨矿介质的类型和浮选电化学环境对浮选过程的影响,展望了硫化铜镍矿浮选技术发展趋势,指出加强磁选、生物浸出等非浮选工艺的研究能强化镍资源的回收。
[Abstract]:In view of the flotation separation technology of copper nickel sulfide ore, the separation of copper and nickel minerals is difficult to be dissociated by monomer, the gangue minerals containing magnesium are easy to be mixed, and the chemical changes of solution during grinding and separation are summarized in detail. The technical difficulties such as high copper-nickel mutual content in the separation of copper and nickel are introduced in this paper. The technological characteristics and applications of preferential flotation, mixed flotation, stage grinding and floatation, pre-desliming flotation and leaching are introduced respectively. The application of new flotation reagents in the separation of copper and nickel sulphide ores is summarized. The effects of the type of grinding medium and the electrochemical environment of flotation on the flotation process are analyzed. The development trend of flotation technology of copper nickel sulphide ores is prospected. It is pointed out that the study of non-flotation processes such as magnetic separation and bioleaching can enhance the recovery of nickel resources.
