摘要

摘要: 高浓度钒液沉钒是影响钒渣钠化球团化焙烧工艺产业化的关键性问题。为了解决这一难题,归纳了曾经产业化应用的水解沉钒工艺和目前大规模产业化应用的酸性铵盐沉钒工艺在高浓度钒液上的研究进展,着重介绍了高浓度钒液三聚氰胺沉钒工艺研究进展。最后针对这些工艺发展现状及存在的优缺点,认为水解沉钒和酸性铵盐沉钒工艺不适合高浓度钒液,指出高浓度钒液沉钒机理、杂质元素对沉钒影响规律及调控机制应是高浓度钒液沉钒今后的研究方向,三聚氰胺沉钒工艺可能是高浓度钒液沉钒的一条新路径。

Abstract: The precipitation of vanadium in a high concentration vanadium solution essentially influences the industrialization of vanadium slag sodiumization pelletizing roasting process.In order to provide a benchmark for solving the problem of vanadium precipitation in high concentration vanadium solution,the research on of hydrolyzed vanadium deposition in high concentration vanadium solution and acid ammonium salt deposition in high concentration vanadium solution had been reviewed,and progress of melamine deposition in high concentration vanadium solution was highlighted.Based on the advantages and drawbacks of these processes,the processes of hydrolyzed vanadium and acidic ammonium salt vanadium precipitation are thought not suitable for high concentration vanadium solution.The mechanism of vanadium precipitation with high concentration liquid and the influence of impurity elements on vanadium precipitation and the regulation mechanism should be investigated when taking into account of vanadium precipitation in high-concentration vanadium solution.In addition,it should be noted that melamine precipitation of vanadium can be a novel way of precipitating vanadium in a high-concentration vanadium solution.
