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。
According to the characteristics of vanadium-titanium magnetite and ilmenite in a sample of vanadium titanomagnetite in Yunnan Province that are coarse and fine-grained and contain a large amount of weakly-magnetic phlogopite, the “grinding- Magnetic separation, coarse selection of spiral chute - titanium coarse concentrate fine grinding - weak magnetic separation of iron - high gradient magnetic separation, shaker Featured Titanium ”new technology, access to iron grade and V2O5 grade were 65.97% and 0.93% of vanadium Titanium magnetite concentrate, iron recovery rate and V2O5 recovery rate of 54.98% and 57.75%, respectively, and Ti O2 grade and Ti O2 recovery rates of 42.26% and 31.19%, respectively, for the development of such mineral resources Use laid the technical foundation.
