How to Make Ferro Vanadium?

    Industrial Production Routes for FeV from Vanadium Pentoxide Ferrovanadium (FeV)​ is made by reducing vanadium pentoxide (V₂O₅) with a reducing agent in the presence of iron. The two main methods are aluminothermic​ and silicon‑reduction​ (carbothermic) processes.
Process Raw Materials Reaction Vanadium Content Features
Aluminothermic V₂O₅ + Al + Fe scrap/oxide 3V₂O₅ + 10Al → 6V + 5Al₂O₃ 40–80% V Exothermic, self‑sustaining, lower energy input
Silicon‑reduction V₂O₅ + ferrosilicon + Fe 2V₂O₅ + 5Si → 4V + 5SiO₂ 50–80% V Conducted in electric arc furnace, better composition control
Aluminothermic Steps
  1. 1. Blend V₂O₅ with aluminum powder and iron oxide/scrap.
  2. 2. Ignite mixture; highly exothermic reaction produces molten vanadium and aluminum oxide slag.
  3. 3. Iron captures vanadium, forming FeV alloy.
  4. 4. Separate alloy from slag by tapping and cooling; crush to desired size.
Silicon‑Reduction Steps
  1. 1. Charge V₂O₅, ferrosilicon, and iron into electric arc furnace.
  2. 2. Heat to ~1600 °C; Si reduces V₂O₅ to metallic V, which combines with Fe.
  3. 3. Tap molten FeV; cast ingots or break into lumps.
Considerations
  • Slag disposal and gas cleaning needed for environmental compliance.
  • Precise control of reactant ratios ensures target V content and minimizes impurities (P, S).
  • Choice of method depends on plant capacity, energy cost, and desired FeV grade.
