摘　　要：对我国天然铀纯化技术研究作了全面的回顾，对不同历史时期的研究情况作了概述。研究表明，９０年代中期我国已能从粗黄饼开始，经溶剂萃取过程直接制备出核电级硝酸铀酰溶液，标志着我国铀纯化技术水平达到了一个新的水平。随着我国铀纯化技术研究水平的不断提高，我国的铀纯化工艺将步入世界同类技术的先进水平。This paper gives overview of natural uranium purification technical research in China and summarizes the research circumstances in different periods. In the middle of 90's, new process has been developed to produce uranyl nitrate for nuclear power plant directly from rude yellow cake by solvent extraction,which means the uranium purification technique in China has reached new level. With the improvement of researches in this field,the uranium purification process in China willreach the advanced level in the world.
