本文采用强磁抛尾-焙烧磁选法对鹤庆高铁氧化锰矿石的铁与锰的分离进行了研究。在本研究中由于焙烧磁选前采用了强磁抛尾作业,不仅可首先抛去影响最终锰精矿质量的尾矿,还使焙烧磁选为无尾矿选矿,从而对简化工艺流程、降低生产成本创造了良好的条件。
In this paper, ferromagnetic tail-roasting magnetic separation was used to study the separation of iron and manganese from Heqing high-speed ferric oxide ore. In this study, because of the strong magnetic tailing operation before roasting magnetic separation, not only the tailings that affect the quality of the final manganese concentrate can be thrown out first, but also the roasting magnetic separation is tailings-free dressing, so as to simplify the process flow and reduce Production costs have created good conditions.
