| Summary: | This is a paper in the field of metallurgical engineering. Vanadium is a rare strategic metal resource in China, which is used in many fields and is closely related to the national economy. Nowadays, the comprehensive utilization value of vanadium extraction process is becoming more and more significant, and the solvent extraction method for vanadium extraction has attracted extensive attention because of its advantages of strong selectivity and high product purity. In this paper, the roasting, leaching, purification and enrichment and vanadium precipitation technology were reviewed. The research work and methods of vanadium separation by solvent extraction were summarized, and the extraction of vanadium by tertiary amine extraction agent and its development status at home and abroad were discussed emphatically.
