摘　　要：钒铬在自然界中常以伴生矿物—钒钛磁铁矿的形式共存,这一特性在资源提取阶段对钒铬的高效分离构成了显著的技术挑战,鉴于这一问题,系统分析了目前提钒工艺中普遍采用的几种钒铬分离技术,如化学沉淀法、离子交换法和溶剂萃取法等在应用过程中表现出的优势和存在的问题。指出探索更加高效、经济的钒铬分离方法是当前研究的重点,同时,未来的钒铬分离技术上应加强环保技术的研究与应用,解决分离过程中产生的废水、废渣等环境问题,从而实现高效、绿色、可持续生产。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.
