苏联恰图拉和尼科波尔地区锰矿选矿厂洗矿锰矿泥的选别,目前最常用的方法是浮选。浮选给矿粒度为-0.16+0.04mm。对粗颗粒要磨矿到-0.16mm,而细粒(-0.04mm)则送入尾矿场。此时锰的损失达20～22％。黑色金属选矿研究设计院提出了强化锰矿泥选别过程的两个方向:1)提高浮选的粒度上限:2)寻求细泥的处理方法。
Currently, the most commonly used method for flotation of manganese ore is manganese ore dressing at the manganese ore dressing plant in the Chatitra and Nicobol areas of the Soviet Union. Flotation ore size is -0.16 + 0.04mm. The coarse particles should be ground to -0.16mm, while the fine particles (-0.04mm) are fed to the tailings. At this time the loss of manganese up to 20 to 22%. Black metal beneficiation Research and Design Institute proposed to strengthen manganese ore separation process in two directions: 1) increase the upper limit of flotation size: 2) to find a fine mud treatment.
