A novel process for the extraction of iron, titanium, vanadium, and chromium from high-chromium vanadium-bearing titanomagnetite concentrates is proposed. This process involves several steps: partial reduction of the concentrates, magnetic separation, hydrochloric acid leaching of the titanium-bearing tailing, and alkaline desilication of the HCl leach residue. The partial reduction ensures that the...
A novel process was proposed for preparing titanium dioxide by the decomposition of titanium slag in sodium hydroxide system under atmospheric pressure. The kinetics on the decomposition of titanium slag was mainly investigated. The results on effect of reaction temperature, particle size and NaOH-to-slag mass ratio on titanium extraction show that the temperature and particle size have significant...
