在矿石工艺矿物学研究的基础上,通过磁选、重选等系列试验研究,确定了某海滨砂矿的最佳选矿工艺流程及工艺指标。工艺矿物学研究表明,钛、铁共生紧密,难以分离,可作为钛磁铁矿回收利用。原矿磁选试验结果表明,采用湿法预选-磨矿-磁选流程得到的钛磁铁矿精矿:Fe品位为60.28%,回收率为76.13%,TiO2品位为12.62%,回收率为62.06%。尾矿重选试验结果表明,采用一粗一精的摇床选别流程得到的精矿:Fe品位为46.70%,作业回收率为68.45%,TiO2品位为22.02%,作业回收率为79.01%。
Based on the research of mineralogy and mineralogy, the best beneficiation process and technical index of a beach seashore have been determined by the series of experiments such as magnetic separation and reselection. Process mineralogy studies have shown that titanium, iron symbiosis close, difficult to separate, can be used as titanium magnetite recycling. The results of ore magnetic separation test showed that the titanomagnetite concentrate obtained by wet preselection-grinding-magnetic separation process has a Fe grade of 60.28%, a recovery of 76.13%, a TiO2 grade of 12.62% and a recovery rate of 62.06% . Tailings re-election test results show that the use of a crude-refined shaker election process to obtain the concentrate: Fe grade was 46.70%, operating recovery was 68.45%, TiO2 grade was 22.02%, operating recovery was 79.01%.
