Hydrothermal alteration and its effects on Ti-V deportment and processing of the Middle Ore Layer (MOL) from the Mustavaara Fe-Ti-V deposit, Finland

The Mustavaara Fe-Ti-V deposit located 53 km southwest of Kuusamo, northern Finland, represents a significant vanadium resource hosted within the Koillismaa (2.44 Ga) layered intrusion complex. As part of the Horizon Europe AVANTiS (HE AVANTiS)-project, this study investigates the impact of hydrothermal alteration on titanium and vanadium deportment within the Middle Ore Layer (MOL) of the Mustavaara deposit. The research contributes to AVANTiS's goal of developing innovative solutions for sustainable vanadium and titanium production in Europe by providing a detailed understanding of the distribution of critical and strategic elements within the Mustavaara and other oxide deposits in Europe.
