四川某钒钛磁铁矿选铁试验研究

Experimental Research on Separating Iron from a Vanadous Titanomagnetite Ore in Sichuan

对四川某钒钛磁铁矿进行了粗粒抛尾、阶段磨选、一段磨选三种磁选选铁工艺流程的对比试验,结果表明:选取阶段磨选工艺作为该矿石选别流程,最终可获得TFe品位57.60%、含TiO212.66%、铁金属回收率61.62%的铁精矿。

The experimental research on separating iron from a vanadous titanomagnetite ore in sichuan was carded out. Comparison tests of three technological flowsheets of discarding the tailings at coarser size, stage grinding - stage separating, and one - stage grinding and separating for magnetic separation of iron were performed. The results showed that when the technology of stage - grinding and stage - separating is selected as a mineral processing flow- sheet for separating iron from the vanadous titanamagnetite ore, an iron concentrate of 57.60% TFe（ containing 12. 66% TiO2） can be obtained with a recovery of 61.62%.
