摘　　要：长江三峡库尾 (重庆段 )淤砂含钪 6.6g t ,采用了螺旋抛尾、粗精矿磨矿分级、重选 磁选、重选 电选联合选矿工艺流程 ,得到了钪品位为 96.2 3g t,回收率为 62 .11%的钪精矿 。The runway silt in the tail sector of the Three Gorges reservoir (the sector in Chongqing) contains scandium of 6.6 g/t. A scandium concentrate which has a grade of 96.23 g/t and a recovery of 62.11% has been obtained by the process of spiral concentration-primary concentrate grinding-gravity separation-magnetic separation-gravity reseparation-electric concentration. It creates favourable conditions for the further extraction of scandium.
