摘要: SLon-4000磁选机是赣州金环磁选设备有限公司最新研制的最大型号脉动高梯度磁选机,具有处理量大、性能稳定、操作维护方便、能耗低和占地面积小等优点。攀钢某尾矿综合回收选矿厂为解决从攀钢选钛厂尾矿中再回收钛时以螺旋溜槽为粗选设备存在的钛粗精矿回收率低下(仅10%左右)问题,进行了用SLon-4000磁选机代替螺旋溜槽的工业试验。结果表明,在给矿TiO2品位为6.20%的情况下,可获得TiO2品位为13.22%、TiO2回收率为61.88%的钛粗精矿,TiO2回收率比采用螺旋溜槽时提高了50个百分点以上。产品筛析结果显示,该设备对-400目粒级中钛的回收率可达59.51%。

Abstract: SLon-4000 separator is the largest pulsating high gradient magnetic separator newly developed by SLon Magnetic Separator Co.,Ltd.,with advantages as large throughput,stable performance,easy operation and maintenance,low consumption and small occupation etc..In order to solve the low recovery of coarse titanium concentrate (only about 10%) with spiral chute in titanium recovery from tailings of Pangang dressing plant,industrial tests are made by SLon-4000 magnetic separator instead of the spiral chute.The results indicated that for feeds with the TiO2 grade of 6.20%,coarse titanium concentrate with TiO2 grade of 13.22% and TiO2 recovery of 61.88% was obtained.TiO2 recovery is increased by 50% or more comparing with the spiral chute.Product analysis results show that SLon-4000 magnetic separator realizes the Ti recovery of up to 59.51% at -400 mesh.
