摘 要: 战略金属钨钒资源的供给对保障国民经济和国防事业的可持续发展意义重大。随着优质矿产资源的减少以及双碳背景下资源绿色加工的迫切需求,二次资源中钨钒的资源化利用具有重要的研究价值。目前,国内外学者在钨钒资源高效浸出方面已开展了卓有成效的研究,而针对溶解态钨钒分离的研究,缺少兼具选择性、高效性和实用性的分离提取工艺,限制了二次资源中钨钒的资源化利用。本文首先对钨钒矿产资源与二次资源进行分析,简要概述了含钨钒二次资源的浸出和除杂工艺;其次着重对溶解态钨钒分离的原理、方法、研究进展进行归纳总结;最后提出一种钨钒分离的新思路,深入探讨了该技术的起源、原理和发展现状,以及其应用于溶解态钨钒分离的优势与发展前景,为溶解态钨钒的选择性深度分离提供新的研究思路。

Abstract:Supply security of the strategic metals, tungsten and vanadium, is of great significance toensuring the sustainable development of the national economy and defense. With the depletion of high-quality mineral resources and the urgent need for green processing of resources under the dual-carbon background, the resource utilization of tungsten and vanadium in secondary resources has important research value. Currently, productive researches on the efficient leaching of tungsten and vanadium from the secondary resources has been conducted by domestic and foreign scholar, however, the research on the separation of dissolved tungsten and vanadium lacks a selective, efficient and practical separation and extraction process, which limits the resource utilization of tungsten and vanadium in secondary resources. In this paper, the mineral resources and secondary resources of tungsten and vanadium were analyzed, and the leaching and impurity removal processes of secondary resources containing tungsten and vanadium were briefly summarized firstly. The principles, methods, research progress of the separation of dissolved tungsten and vanadium were then summarized emphatically. Finally, a new idea for separation of tungsten and vanadium was proposed, and the origin, principle and development status of the technology, as well as its advantages and development prospects for the separation of dissolved tungsten and vanadium were discussed, it aims to provide new research ideas for the selective deep separation of dissolved tungsten and vanadium.
