摘　　要：采用溶剂萃取对含氟硫酸体系铍浸出液进行铍与氟、铝、铁的高效分离。通过试验得出最佳工艺参数：萃取剂为P204,萃取前需采用亚硫酸钠还原,萃取p H 1.5~2.0,皂化率33%,萃取时间20 min,O/A=3∶2,F/Be O=1,通过六级逆流萃取,Be O萃取率可达到99%以上。High efficient separation of beryllium,fluorine,aluminum and iron of beryllium leaching solution containing fluorine by solvent extraction was studied. The optimum parameters obtained by tests were as follows： the exacting agent is P204,use sodium sulfite to reduct before extraction,extraction p H is 1. 5 ~ 2. 0,saponification rate 33%,time20 min,O / A 3∶ 2 and F / Beo 1. By six counter current extraction,the extraction rate of Be O can reach 99%.
