摘要
滇西某铁矿Fe品位为13.66%,且主要以嵌布粒度细的磁铁矿形式存在。针对原矿品位低及矿物嵌布粒度细等特点,采用"粗磨-弱磁粗选-粗精矿再磨-弱磁精选"的工艺流程。可获得铁精矿Fe品位64.47%,回收率56.87%的指标,为此类矿石的选别提供参考。
A iron ore from western Yunnan Fe grade of 13.66%, respectively, and most of Fe elements are finely distributed in magnetite mineral. In response to the characteristics of low grade and fine distribution, A primary grinding- low intensity magnetic separation-rough concentrate to grinding-low intensity magnetic separation technique was developed, It can get iron concentrate Fe grade of 64.47% and Fe recovery 56.87%, The technique provides a reference for the iron ore.
