Outline
In view of the complex state of vanadium occurrence in vanadium resources, the high difficulty in extraction and separation, and the increasingly strict environmental protection requirements, this paper systematically summarizes the research progress of vanadium extraction processes at home and abroad, and focuses on discussing the technical characteristics and existing problems of representative vanadium extraction processes such as roasting-leaching, hydrometallurgical separation, and others. According to the properties of different raw materials such as vanadium-titanium magnetite and vanadium-cotaining shale, the suitable routes of the listed vanadium extraction processes are compared and analyzed. Proposing that future vanadium extraction processes should develop towards the direction of low pollution, high recovery rate, intelligence, short process, and efficient comprehensive utilization of resources, is an important way to promote the improvement and innovation of vanadium metallurgy technology.
