Experimental study on high-efficiency beneficiation of fine-grained olivine pyroxene ilmenite

  • 摘要: 针对攀西地区某选厂细粒橄辉岩型钛铁矿粒度细,橄榄石脉石含量高,常规的螺旋选矿机和强磁无法对其进行高效富集的难点,开发了一种重选组合流程—“新型螺旋+悬振锥面选矿”,对其进行预富集后再浮选。相比强磁作业,新工艺所获得的产率能提高8.24%,浮选给矿TiO2品位提高2个百分点,富集作业尾矿TiO2品位下降4个百分点,浮选作业药剂成本大幅降低,每年能增加钛精矿6万t,从而实现此类型钛铁矿的高效回收。
