Abstract:Vanadium and chromium are scarce and important strategic metals in China, which widely used in metallurgy, chemical industry, pigment, aerospace and other fields, and plays a key role in the national economy. Vanadium is often associated with chromium in minerals. It is difficult to separate vanadium and chromium because of their similar physical and chemical properties. Based on the systematic analysis of the properties of the solution containing vanadium and chromium, the research progress of vanadium and chromium separation methods was reviewed in the case of high vanadium and high chromium solutions. The main methods include chemical precipitation, solvent extraction, crystallization separation, ion exchange and adsorption separation were summarized, and the development trend of vanadium and chromium separation methods was also discussed.
