氯化木素是合成有机化合物,其表示式为:它对铁矿及稀土金属矿物有强烈的抑制作用,可以代替淀粉、糊精及烤胶等而作为上述矿物的有效抑制剂。在用氯化木素作抑制剂对赤铁矿、磁铁矿进行小型及工业的反浮选试验中,不仅得到品位较高的精矿,而且获得了很高的回收率。特别是利用反浮选将磁选精 Lignin chloride is a synthetic organic compound, the expression is: It has a strong inhibitory effect on iron ore and rare earth metal minerals, can replace starch, dextrin and baking gum as the effective inhibitors of the above minerals. In the small and industrial anti-flotation tests on hematite and magnetite with lignin as inhibitor, not only high grade concentrate but also high recovery was obtained. In particular, the use of reverse flotation will be magnetic separation of fine
