Due to the complex and variable nature of vanadium shale components, there are still problems such as low efficiency and poor adaptability in sorting pretreatment; in terms of high-purity vanadium extraction and deep processing, there is still significant space for improvement in consumption reduction, efficiency enhancement, and reduction of metal loss rate. This article provided a systematic overview of research work on the preconcentration of vanadium shale resource beneficiation, main process of extracting vanadium (including high temperature oxidation, leaching of hydrometallurgy, single metal separation, etc.), link adaptation of high-end vanadium materials, etc. from the perspective of the industrial chain. The paper focus on the latest technological progress of vanadium shale since the 13th Five-Year Plan, and looks forward to the future technological development direction. The whole industrial chain technology research and development of efficient source extraction, fine control of the process, and high-value vanadium material manufacturing promote vanadium shale utilization and industrial production integrated demonstration construction and support the green and sustainable development of national strategic vanadium shale resources.
