摘　　要：根据赤泥的基本性质和综合处理的现状,研究提高赤泥中稀有金属钪回收率。采用逆流循环浸出赤泥,通过调节浸出过程中各影响因素,最佳工艺条件为:硫酸浓度900～1000g/L,浸出温度90℃以上,液固比5∶1,浸出时间4h,钪的综合回收率达到85%以上。According to the basic nature of the red mud and comprehensive treatment of the status quo, research to improve the recovery rate of red mud in the metals scandium. This paper uses counter - current leaching of red mud circulation, by adjusting the various factors affecting the leaching process, so that the final recovery of scandium integrated more than 85%.
