摘要
钒及其化合物作为重要的战略性资源,因具有特殊的物理化学性质,被广泛应用于冶金、化工、航空航天、国防军事等核心领域,如何低成本绿色高效回收钒渣中的钒资源,是保证我国钒产业可持续发展的重要举措。本文系统总结了国内外主要提钒工艺研究现状,包括焙烧(无盐焙烧、钠化焙烧和钙化焙烧)-浸出(水浸、酸浸和碱浸)-回收(水解、铵盐沉钒、溶剂萃取和离子交换)-煅烧等,并对提钒工艺的未来研究方向进行了展望,以实现提钒工艺高效率、低成本、无污染的绿色化发展。
Abstract
Vanadium and its compounds, as important strategic resources, are widely used in core fields such as metallurgy, chemical industry, aerospace, national defense and military due to their special physical and chemical properties. How to recover vanadium resources from vanadium slag in a low-cost, green and efficient manner, is an important measure to ensure the sustainable development of China's vanadium industry. This article systematically summarizes the current research status of major vanadium extraction processes at home and abroad, including roasting (non-salt roasting, sodium-roasting and calcium-roasting)-leaching (water-leaching, acidic-leaching and alkaline-leaching)-recovery (hydrolysis, ammonium precipitation, solvent extraction and ion exchange)-calcination, and looks forward to the future research directions of vanadium extraction processes to achieve high-efficiency, low-cost, and pollution-free green development of vanadium extraction processes.
