用钛铁矿精矿制取富钛料的方法
摘要：
一种用钛铁矿制取富钛料的方法,是将磨细后的钛铁矿配入一定重量百分比的粘结剂和添加剂造球,球团经冷固结球团法或预热球团法固结后,置于回转窑中于1100～1150℃温度下直接还原,还原产品经磨碎磁选分离,得到富钛料和铁粉精矿;该方法与常规方法相比,还原温度降低130～220℃,富钛料酸解性能好,并且TiO2品位提高10%左右,Fe、TiO2回收率分别提高20%、5%左右。
摘要（英）：

A process for preparing the Ti-enriched material from ilmenite concentrate includes grinding ilmenite concentrate, mixing it wich additive and adhesive, sphericizing, solidifying, direct reducing at 1100-1150 deg.C in rotary kiln, grinding and magnetic separation to obtain Ti-enriched material and powdered iron concentrate. Its advantages include lower reducing temp lowered by 130-220 deg.C, highacidolysis performance of Ti-enriched material, high grade of TiO2 and high recovery rate of Fe and TiO2 increased by 20% and 5% respectively.
