摘　　要：在传统、三出口、组合联动轻稀土萃取分离工艺研究分析的基础上,设计开发了带模糊分离和置换萃取等技术的组合联动轻稀土萃取分离新工艺流程,并与传统工艺进行了技术经济比较。经比较证明,组合联动轻稀土分离新工艺先进合理,充槽投资更省,生产成本更低,生产废水排放更少。Based on the research of light rare earth extraction process of traditional method,three exports and combined linkage,a new combined linkage light rare earth extraction process with fuzzy separation and replacement extraction was designed and developed,and compared with the traditional process technical economy.The result showed that the new process is advanced and more rational,and the cost of full-tank material is lower,the production cost is lower,and wastewater discharges less.
