摘要: 对包钢选矿厂强磁选粗精矿经磁化焙烧—弱磁选所得尾矿进行稀土的选矿工艺研究。试验结果表明,弱磁选尾矿经预先脱碳并经混合浮选后得到的混合浮选精矿,对其进行了单一流程及一次粗选、三次精选、一次扫选的全流程试验研究,最终获得了REO品位64.41%,回收率18.13%的稀土精矿产品。同时,对试验流程的改进和优化提出了建议。

Abstract: Study was made on the beneficiation process for recovering rare-earth from the low intensity magnetic separation (LIMS) tailing of high intensity magnetic separation (HIMS) rougher concentrate after magnetizing roasting in Baogang concentrator.Tests were made on the single flowsheet and a whole-flowsheet consisting of one rougher, three cleanings and one scavenging for treating the concentrate obtained from the bulk flotation of LIMS tailing after carbon removal.The test results show that a rare-earth concentrate product having a REO grade of 64.41% and a recovery of 18.13% can be obtained.Suggestions are made on the improvement and optimization of the test flowsheet.
