| 摘 要： | 对从河道淤砂中提取钪的新工艺进行了研究。试验考察了盐酸、硝酸、硫酸以及盐酸加助溶剂浸出钪时各因素的影响和浸出效果，以及氯化焙烧浸出、碱熔合浸出的浸出效果。试验结果表明，在三种酸的浸出试验中HN03浸出率为59．20％，略高于盐酸，但盐酸加助熔剂浸出率高达80．94％。而氯化焙烧浸出、碱熔合一水解浸出的浸出率分别高达82，79％和99．79％。

| Abstract: | Recovery of Sc from runway silt was studied.Investigation was made on the impaction of each factor on the leach of HCl,HNO_3 and H_2SO_4.The results showed that the HNO_3 recovery was higher than HCl,which was 59.20%.But the recovery of HCl added solution aid was 80.94% and the recovery of chlorinate-roast-leach was 82.79% and that alkaline-fuse-leach was 99.79%. |
