Comprehensive Utilization Status and Development of Vanadium-bearing Solid Wastes

It is well know that vanadium-bearing solid waste has become an important research object for resource recovery and environmental treatment, which due to its more kinds, valence elements and complex phase composition. According to the problem of urgent treatment of vanadium containing solid waste, the types and sources, as well as the resource characteristics of dvanadium-bearing solid wastes in China, were analyzed.The main methods of high-value utilization of vanadium-bearing solid wastes were concluded, including the extraction of valuable elements, multi-component comprehensive utilization and overall value-added utilization; The paper also summarized the utilization status and development of the application of vanadium-bearing solid waste in the field of structural materials, iron and steel metallurgy, functional materials, ecological and environmental protection. In addition, the problems existing in the waste comprehensive utilization of vanadium containing solid waste were given. The resource processing development trend of vanadium containing solid waste was put forwards, such as expanding to the preparation of geopolymer, refractory, rubber and plastic filler, and other utilization fields with zero discharge and high additional value.
