摘　　要：攀西某超低品位钒钛磁铁矿为了回收利用总尾矿中的钛资源,在尾矿性质研究的基础上,进行了重选尾矿再回收试验。试验结果表明:尾矿通过强磁选—分级—弱磁选工艺,可得到全铁品位为19.07%、TiO_(2)品位为18.25%的入浮矿样;对入浮矿样开展脱硫—1粗3精开路浮选,可得到TiO_(2)品位47.27%、TiO_(2)回收率70.78%的合格钛精矿,同时分级后的粗粒级矿物通过重选工艺,在摇床床面精矿与尾矿的截取比例为2∶8的条件下,可获得精矿产率为6.46%、全铁品位为13.41%、TiO2品位为8.83%的钛原料,能够并入主系统对其中的钛金属进行再次选别回收,以获得更高的钛资源综合利用率。In order to recycle the titanium resources in the total tailings of an ultra-low grade vanadi⁃um-titanium magnetite in Westem Panzhihua,based on the study of tailings properties,the re-recovery test of gravity tailings was carried out.The test results show that the flotation sample with total iron grade of 19.07% and TiO_(2) grade of 18.25% can be obtained by high intensity magnetic separation-classification-low intensity magnetic separation process.The qualified titanium concentrate with TiO_(2) grade of 47.27% and TiO_(2) recovery of 70.78% can be obtained by open-circuit flotation with desulfurization-1 roughing and 3 cleaning of the ore samples entering flotation.The coarse-grained minerals after classification are subjected to gravity separation process,under the condition that the interception ratio of the concentrate and tailings of the shaking table surface is 2∶8,the titanium raw material with the concentrate yield of 6.46%,the total iron grade of 13.41% and the TiO2 grade of 8.83% can be obtained.It can be incorporated into the main sys⁃tem to separate and recycle the titanium metal again,so as to obtain higher comprehensive utilization rate of titanium resources.
