摘要
为综合回收某低品位钛铁矿中的钛、铁资源,在矿石性质研究基础上,进行了弱磁选-再磨再选回收铁、钛的选矿试验研究。结果表明,磨矿细度-0.074 mm粒级占84.78%时进行弱磁选,所得铁精矿TFe、TiO_(2)品位分别为62.82%和3.62%,铁回收率为51.32%,磁性铁回收效果良好;对弱磁选尾矿进行一粗一精强磁选-摇床重选联合流程试验,得到TiO_(2)品位40.81%、钛回收率18.47%的钛精矿,铁和钛均得到综合回收。
In order to comprehensively recover titanium resources and iron resources from a low-grade ilmenite ore,an experimental study was performed for the ore by a process of low intensity magnetic separation(LIMS)followed by regrinding and re-concentration to recover Ti and Fe therein.The results show that LIMS with ore at a grinding fineness of-0.074 mm 84.78%can yield an iron concentrate grading 62.82%TFe and 3.62%TiO_(2) with iron recovery of 51.32%,presenting a good recovery of magnetic iron;the obtained LIMS concentrate is subjected to high-intensity magnetic separation(HIMS)consisting of one roughing and one cleaning,followed by gravity separation with a shaking table,resulting in the obtained Ti concentrate grading 40.81%TiO_(2) at 18.47%recovery.It is shown that both Fe and Ti therein can be comprehensively recovered.
