Abstract:As the demand for vanadium-containing products continuously increasing,the output of vanadium extraction tailings has also increased year by year. If it is not effectively and comprehensively utilized,it will not only occupy a large amount of land,cause a lot of waste of valuable metals,but also cause serious pollution to the environment. Combined with the physical and chemical characteristics of vanadium extraction tailings, the research progress of vanadium extraction tailings in four aspects are reviewed,such as the recovery of valuable components,preparation of special functional materials,removal of harmful elements,and production of building materials. At present,although some progress has been made in the comprehensive utilization of vanadium extraction tailings,there are still disadvantages such as the insufficient economy and environmental protection,and limited consumption. With the continuous improvement of people′s awareness of environmental protection and the decrease of high-grade rich ore reserves year by year. The comprehensive utilization of vanadium extraction tailings in the future will inevitably lead to the comprehensive recovery of multiple valuable elements,reducing the content of toxic and radioactive elements in productions. At the same time,it is necessary to further simplify the process flow and use the vanadium extraction tailings to prepare high value-added products,so as to reduce production costs,expand the use range of products,increase the consumption of vanadium extraction tailings,and achieve environmental protection and sustainable development of economic growth.
