摘　　要：研究表明，浮选前先磁选能有效控制游离铁离子进入浮选体系；磁选精矿经反浮脱硅和正浮选可获得合格菱镁矿精矿。ＦＳＮ可改变菱镁矿、白云石的Ｚｅｔａ电位并使两者之间可浮性差异明显提高。The studies show that magnetic separation before flotation can control iron ions from getting into flotation system effectively, and the qualified magnesite concentrate can be obtained from the former concentrate by the process of 'magnesite flotation after reverse flotation desilication '. The activator FSN can change Zeta-potential of magnesite and dolomite and enlarge the difference of flotability between the two minerals. The optimum value of pH is 89 for selective flotation of magnesite.
