| Abstract: | 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. |
