摘要
针对云南某钒钛磁铁矿试样中钒钛磁铁矿和钛铁矿分别呈粗、细粒分布并含有大量弱磁性金云母的特点,采用"磨矿-弱磁选铁-高梯度磁选、螺旋溜槽粗选-钛粗精矿细磨-弱磁选铁-高梯度磁选、摇床精选钛"新工艺,获得铁品位和V2O5品位分别为65.97%和0.93%的钒钛磁铁矿精矿,铁回收率和V2O5回收率分别为54.98%和57.75%,及Ti O2品位和Ti O2回收率分别为42.26%和31.19%的钛精矿,为该类矿产资源的开发利用奠定了技术基础。
In an ore sample from Yunnan province,the vanadium-titanium magnetite and the ilmenite respectively distributed in coarse and fine particles,with abundant weakly magnetic phlogopites. According to this characteristic,a new processing technique was proposed,including grinding-iron separation by LMS-HGMS,roughing by spiral chute-fine grinding of primary titanium concentrate-iron separation by LMS-HGMS,and titanium cleaning by shaking table. The vanadium-titanium magnetite concentrate containing Fe 65. 97% and V2O50. 93%,with Fe recovery of 54. 98% and V2O5 recovery of 57. 75%,was obtained. Meanwhile,the ilmenite concentrate containing T 42.26%,with recovery of 31. 19%,was achieved. This study provided a technical foundation for the utilization of such ores.
