Abstract

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.
