It is suggested that efforts should be made in China for a better and stronger vanadium industry based on rich vanadium resources, encourage鄄ment from Chinese government and relatively stable market demand for vanadium products. In the paper, it is pointed out that waste water and tailings from vanadium extraction can be recycled in the cleaner pro鄄duction process of vanadium oxide using vanadium鄄bearing titaniferous magnetite as raw material, which can solve the potential pollution problems caused by waste water with high ammonia nitrogen and sodium salt from the extraction. Cleaner and high efficient vanadium oxide production technology will be a pre鄄vailing technology in the future and the success of this project is a revolutionary technical innovation for the global vanadium industry.
