摘　　要：某低品位钒钛磁铁矿为综合回收其粗粒磁选尾矿中的钛资源,在矿石性质研究的基础上,进行了钛回收工艺试验研究。试验结果表明:原矿通过分级—一段强磁选—磨矿弱磁除铁—二段强磁选—浮选工艺可得到TiO_(2)品位47.26%、TiO_(2)回收率19.34%的钛精矿,选别指标较好;工业应用结果表明,一段强磁精矿回收量为290 550 t,TiO_(2)平均品位为11.31%,高于选矿车间选钛入选原料质量要求,每年可增加利润3 146万元,经济效益和社会效益显著。In order to comprehensively recover titanium resources from the coarse magnetic separation tailings of a low-grade vanadium-titanium magnetite ore,an experimental study on titanium recovery pro⁃cess was carried out based on the study of ore properties.The test results show that the ilmenite concentrate with TiO_(2) grade of 47.26%and TiO_(2) recovery of 19.34%can be obtained by the process of classification-one stage high intensity magnetic separation-grinding and low intensity magnetic separation iron removal-two stage high intensity magnetic separation-flotation,and the separation index is good.The industrial applica⁃tion results show that the recovery of one stage high intensity magnetic concentrate is 290550 t,and the av⁃erage grade of TiO_(2) is 11.31%,which is higher than the quality requirements of the raw materials for titani⁃um separation in the beneficiation workshop.The annual profit can be increased by 31.46 million yuan,and the economic and social benefits are remarkable.
