Vanadium is one of those materials. It belongs to the categories of ‘critical materials’ and ‘battery materials’ (U.S. Department of the Interior 2018 and European Commission 2020) and is predicted to benefit from high market growth projections because of its use in vanadium redox flow batteries (VRFBs) (Hund et al. 2020).
Due to its porous Structures, sodium-doped vanadium oxide is widely used in energy storage materials.
Nowadays, As one of the most popular vanadium based materials in recent studies, Due to the vanadium sulfides having an even higher electrical conductivity and Li ion diffusion rate than vanadium oxides, people's focus is mainly on VS 2, V 3 S 4 and their composites. 4.1. Vanadium disulfide
Furthermore, vanadium is also found as V 4+ in organic material attached on sedimentary particles (Breit and Wanty 1991) and depending on the nature of the thermal stability of organic material, vanadium may remain associated with organic material during diagenesis and low-grade metamorphism (Zhang et al. 2015).
Zhao et al. (2014) proposed an alternative method for the recovery of vanadium, chromium and titanium from titanomagnetite ores (Fig. 9). The ore is roasted under reducing conditions to selectively reduce iron. The iron is then removed by magnetic separation, and the non-magnetic material leached in hydrochloric acid.
Since vanadium is also a ‘specialty material’ (i.e. global production does not exceed 200 000 tonnes per year), it is essential to consider the size of market base and the structure of the supply chain before and during the planning of exploration and development activities (Simandl et al. 2021).
