越南某钛铁砂矿选矿试验

越南某钛铁砂矿粒度为-80目占62.34%，TiO₂品位为6.04%，主要金属矿物为钛铁矿和钛磁铁矿，部分钛铁矿物已单体解离。为高效开发利用该矿石资源，对有代表性的矿石进行了选矿试验研究。结果表明：①矿石采用1粗1精摇床重选、重选中矿1次强磁选均可获得较高品位的钛铁精矿；②矿石经1粗1精摇床重选，重选中矿1次强磁选，重选尾矿和强磁选尾矿合并再磨至-200目占80%后经1粗2精、中矿顺序返回浮选流程处理，最终获得了TiO₂品位为46.45%、回收率为77.52%的钛铁精矿。

Beneficiation Experiments of ilmenite Ore from Vietnam

In Vietnam there is a ilmenite mine with TiO₂ grade of 6.04% and particle size of 62.34% passing 80 mesh.The main metallic minerals are ilmenite and titanomagnetite，and parts of ilmenite have been liberated.In order to make highly efficient exploitation and utilization of the ore，dressing experiments have been done on the representative samples.The results indicated that：①Through the process of gravity of one roughing-one cleaning gravity separation by shaking table，and one stage high intensity magnetic separation for the middlings from the gravity，high quality of Ti-Fe concentrate was obtained.②Through the process of one roughing-one cleaning gravity separation by shaking table，and one stage high intensity magnetic separation for the middlings from gravity，one roughing-two cleaning flotation for mixed tailings of gravity and magnetic separation after regrinding at 80% passing 200 mesh，Ti-Fe concentrate with TiO₂ grade of 46.45% and recovery of 77.52% was obtained.
