对陕西某选矿厂选铁尾矿进行了回收钛铁矿的实验研究。选铁尾矿经弱磁?强磁?磨矿?强磁工艺所得的精矿，再经浮选回收钛铁矿。以H2 SO4为调整剂，草酸为抑制剂，FAT－3为钛铁矿捕收剂，采用1粗5精浮选工艺流程，最终获得了精矿TiO2品位47．13％、回收率74．96％的试验指标，实现了尾矿中钛铁矿的回收。
對陝西某選礦廠選鐵尾礦進行瞭迴收鈦鐵礦的實驗研究。選鐵尾礦經弱磁?彊磁?磨礦?彊磁工藝所得的精礦，再經浮選迴收鈦鐵礦。以H2 SO4為調整劑，草痠為抑製劑，FAT－3為鈦鐵礦捕收劑，採用1粗5精浮選工藝流程，最終穫得瞭精礦TiO2品位47．13％、迴收率74．96％的試驗指標，實現瞭尾礦中鈦鐵礦的迴收。
대협서모선광엄선철미광진행료회수태철광적실험연구。선철미광경약자?강자?마광?강자공예소득적정광，재경부선회수태철광。이H2 SO4위조정제，초산위억제제，FAT－3위태철광포수제，채용1조5정부선공예류정，최종획득료정광TiO2품위47．13％、회수솔74．96％적시험지표，실현료미광중태철광적회수。
In the test on recovering ilmenite, tailings from iron?ore separation in a concentrator in Shaanxi were subjected to a process flowsheet of LIMS?HIMS?grinding?HIMS, the concentrate collected therefrom was beneficiated to obtain ilmenite by a further flotation process of one stage of roughing and five stages of cleaning with H2 SO4 as regulator, oxalic acid as inhibitor, and FAT-3 as ilmenite collector. The TiO2 grade and recovery of ilmenite concentrate are 47?13% and 74.96%, respectively, and therewith a recovery of ilmenite from tailings was actualized.
