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.

Key words: Magnetizing roasting-LIMS tailing, Flotation of rare-earth minerals, XQ₁₀₇ collector
