Abstract

Abstract

Vanadium and chromium commonly coexist in nature as associated minerals in vanadium-titanium magnetite, which presents a significant technical challenge for their efficient separation during resource extraction. In light of this issue, several commonly employed vanadium and chromium separation techniques in current vanadium extraction processes, such as chemical precipitation, ion exchange, and solvent extraction, have been systematically analyzed in terms of their advantages and existing problems during application. It was emphasized that the development of more efficient and economical vanadium and chromium separation methods remains a key focus of current research. Furthermore, future vanadium and chromium separation technologies should prioritize the research and application of environmentally friendly techniques to address the environmental issues, such as wastewater and waste residue, generated during the separation process, thereby enabling efficient, green, and sustainable production.
