  • Method for processing vanadium-titanium magnetite finished ores by using wet process
    Patent number: 9896742
    Abstract: A method for processing vanadium-titanium magnetite finished ores by using a wet process. The method comprises the steps: extracting vanadium from vanadium-titanium magnetite finished ores and processing, by using the vanadium extraction method, obtained leaching residue by using a wet process, so as to obtain titanium; and calcining the remaining liquid extracted during the vanadium extraction, so as to prepare ferric oxide. The flow of the method is short, and the energy consumption is low, thereby avoiding waste of a titanium resource.
