分析了包钢选矿厂氧化矿弱磁—强磁—反浮选工艺流程现状 ,指出了工艺中存在的不足之处 ,提出了改善磨矿、磁选工艺参数的建议 ;并探讨了从尾矿中回收铁和稀土矿物的可行性。仅从尾矿中充分回收磁铁矿 ,铁选矿回收率即可提高 1 2 9个百分点
The status quo of the weak magnetic - ferromagnetic - reverse flotation process of the oxygenated ore in the Baogang Concentrator was analyzed. Some shortcomings in the process were pointed out. Suggestions for improving the technological parameters of grinding and magnetic separation were put forward. In the recovery of iron and rare earth minerals feasibility. Only fully recovered from the tailings of magnetite, iron ore recovery rate can be increased by 1 2 9 percentage points
