日前,973计划重大项目“稀土资源高效利用和绿色分离的科学基础”在北京大学正式启动。该项目瞄准稀土资源开发和提纯的关键问题,目标之一是筛选出各项指标优于目前通用的P507的新型稀土萃取剂。稀土是不可再生的重要战略资源,虽然我国稀土资源蕴藏量大,但稀土资源综合利用率低、开采和冶炼过程污染严重,关键高纯产品依然受限于人,严重影响了我国稀土产业的可持续发展。稀土高效提纯的问题成为制约我国稀土产业发展的重大科学问题。该项目研究内容包括:研究新型萃取剂的萃取性能和购效关系,建立新型 Recently, the 973 Major Project “Science Foundation for Efficient Utilization of Rare Earth Resources and Green Separation” was officially launched at Peking University. The project aims at the key issues of exploitation and purification of rare earth resources. One of the goals of this project is to screen out new rare earth extractants with better indexes than the current P507. Rare earth is an important strategic resource that can not be regenerated. Although there is a large amount of rare earth resources in our country, the comprehensive utilization rate of rare earth resources is low and the pollution of mining and smelting process is serious. The key high purity products are still restricted to people, Continuous development. The problem of efficient purification of rare earth has become a major scientific issue restricting the development of China’s rare earth industry. The project includes: research extraction properties of new extractants and the relationship between efficiency, the establishment of a new type
