钒页岩资源全产业链利用研究现状及发展

Research status and development of the full industrial chain utilization of vanadium shale resources

由于钒页岩组分的复杂多变性特点,在分选预处理方面仍存在效率低、适应性差等问题;在高纯钒提取及深加工方面,降耗、增效、减少金属损失率等仍有较大上升空间。本文以产业链视角,系统综述钒页岩资源分选预处理、钒提取主体工艺(包括:高温氧化、湿法浸出、单金属分离等)、高端钒材链接适配等方面开展的研究工作,重点介绍了钒页岩资源利用最新技术进展,并展望了今后技术发展方向。通过源头高效提取、过程精细控制和高端钒材制造的全产业链技术研发,推动钒页岩利用产业化集成建设,支撑钒页岩资源绿色可持续发展。

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 stil 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.
