摘　　要：某钽铌矿选矿生产过程中产生的次生细泥含(TaNb)2O50.014%,采用脉动高梯度磁选粗选—摇床、螺旋溜槽两次精选,可得到钽铌精矿含(TaNb)2O519.75%,钽铌回收率36.74%,尾矿含(TaNb)2O50.0075%,实现了钽铌资源的有效回收利用。The secondary slimes excreted out in some mining industry company contains （TaNb）2O5 0. 014%. The process of roughing by high grads magnetic, cleaning by once shaking table and twice spiral chute was used for recovery of Ta-Nb. The results showed that the Ta-Nb concentrate with grade （TaNb） 2O5 of 19.75%, recovery rate of 36.74% was obtained. The tailings with grade （TaNb）2O5 of 0. 0098% was remained only. Therefore ,the high efficiency recovery of tantalum and niobium resources is realized in the study.
