【Abstract】 The technology for the separation of Zr and Hf is generally classified into pyrome\| tallurgical technology and hydrometallurgical technology. In this paper, MIBK\|HCNS process, TOA process, TBP\|HCl\|HNO\-3 process and improved N235\|H\-2SO\-4 process were underlined, which are included in solvent extraction, a hydrometallurgical technology. Zr and Hf are mainly used in the nuclear industry, thus the development of Zr and Hf industry is closely linked to the nuclear industry. Strengthening the research on the technology for the separation of Zr and Hf is of important strategic significance for the development of the production of Zr and Hf materials and enhancement of the nuclear power and national defence industries in China.更多还原
