Phase relationship of quaternary system FeO-Al2O3-SiO2-‘V2O3’ at 1873 K and its impact during melting of H-DRI for possible vanadium extraction
The European Union has listed vanadium (V) as one of the critical raw materials for the transition to
a future green society, as stated in the Critical Raw Material Act, written by Grohol and Veeh (2023).
In the steelmaking industry based on V-containing iron ore, V is a possible by-product from the slag.
A requirement for slags to be suitable for V extraction is a V content preferably above 8 wt per cent
as V2O3 and a phosphorus (P) content below 0.1 wt per cent as P2O5. Hence, it is important to keep
V in the slag phase while the P is moved to the metal phase during the steelmaking process.
