摘 要: 戰(zhàn)略金屬鎢釩資源的供給對保障國民經(jīng)濟(jì)和國防事業(yè)的可持續(xù)發(fā)展意義重大。隨著優(yōu)質(zhì)礦產(chǎn)資源的減少以及雙碳背景下資源綠色加工的迫切需求，二次資源中鎢釩的資源化利用具有重要的研究價(jià)值。目前，國內(nèi)外學(xué)者在鎢釩資源高效浸出方面已開展了卓有成效的研究，而針對溶解態(tài)鎢釩分離的研究，缺少兼具選擇性、高效性和實(shí)用性的分離提取工藝，限制了二次資源中鎢釩的資源化利用。本文首先對鎢釩礦產(chǎn)資源與二次資源進(jìn)行分析，簡要概述了含鎢釩二次資源的浸出和除雜工藝；其次著重對溶解態(tài)鎢釩分離的原理、方法、研究進(jìn)展進(jìn)行歸納總結(jié)；最后提出一種鎢釩分離的新思路，深入探討了該技術(shù)的起源、原理和發(fā)展現(xiàn)狀，以及其應(yīng)用于溶解態(tài)鎢釩分離的優(yōu)勢與發(fā)展前景，為溶解態(tài)鎢釩的選擇性深度分離提供新的研究思路。

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.
