Abstract

The results of studies on the extraction separation of REE concentrate isolated from phosphogypsum into 75 vol % TBP in a diluent are presented. The proposed technology has been tested in a pilot plant using an automated cascade of centrifugal extractors of the ETs-10FA model. The design of a centrifugal extractor made of high-molecular-weight polyethylene ETs-1000PB has been developed and its serial production has been mastered. An experimental production has been organized for the separation of REEs with the production of high-purity compounds of cerium, lanthanum, neodymium, and praseodymium on centrifugal extractors.

在离心萃取器上分离稀土元素：开发技术，设计设备和工程生产

摘要

给出了在稀释剂中从磷酸石膏中分离出REE精矿到75％（体积）TBP中的萃取分离的研究结果。提议的技术已经在中试工厂中使用ETs-10FA模型的自动离心提取器进行了测试。已经开发了由高分子量聚乙烯ETs-1000PB制成的离心提取器的设计，并且已经开始批量生产。已经组织了一项实验性生产，用于通过离心萃取器分离稀土元素，并生产高纯度的铈，镧，钕和ase化合物。
