| 摘 要： | 针对细粒低品位钽铌稀土矿,试验研究了＂磁选-重选＂联合工艺。当给矿含（Ta＋Nb）2O50.032%、REO0.092%时,全流程试验可获得含（Ta＋Nb）2O53.444%、REO 12.851%的钽铌稀土精矿,回收率（Ta＋Nb）2O544.13%、REO 57.27%。试验数据证明,该工艺显著提高了钽铌稀土精矿品位及回收率。

| Abstract: | A combined technology, Magnetic-Gravity Separation, has been researched for a fine low-grade RE-Nb- Ta ore. As feeding ore containing 0.032 % of （Ta＋Nb）205 and 0.092 % of REO, a concentrate containing 3.444 % of （Ta＋Nb）205 and 12.851% of REO with recovery of 44.13 % and 57.27 % can be obtained. The grade and recovery of RE-Nb-Ta concentrate was improved significantly by the technology. |
