China, Russia, South Africa, New Zealand, Canada, and Australia are rich in vanadium titanomagnetite (VTM) resources [1]. The Hongge mineral in Panzhihua is the largest VTM resource of China [2]. Hongge vanadium titanomagnetite (HVTM) is an iron ore not only containing iron, titanium, and vanadium, but also relatively rich in chromium.
While vanadium production flow sheets vary between different mines and processing plants, there are a few common features. The process used will vary depending on the nature of the ore. Most vanadium is produced from titanomagnetite ores, either directly or from the slag generated by smelting of titanomagnetite ores.
