Ferrovanadium Production

 Industrial Methods for Manufacturing FeV from Vanadium Pentoxide Ferrovanadium is produced mainly by aluminothermic​ and silicon‑reduction (carbothermic)​ processes, both starting from vanadium pentoxide (V₂O₅).
Process Raw Materials Reaction Principle Vanadium Content in Product
Aluminothermic V₂O₅ + Al + Fe scrap/oxide Exothermic reduction: 3V₂O₅ + 10Al → 6V + 5Al₂O₃ 40–80% V
Silicon‑reduction V₂O₅ + ferrosilicon (or Si metal) + Fe Reduction in electric arc furnace: 2V₂O₅ + 5Si → 4V + 5SiO₂ 50–80% V
Aluminothermic Process Steps
  1. 1. Mix V₂O₅ with aluminum powder and iron oxide/scrap.
  2. 2. Ignite mixture; highly exothermic reaction produces molten vanadium and slag.
  3. 3. Iron captures vanadium to form FeV alloy.
  4. 4. Separate alloy from slag by tapping and cooling.
Silicon‑Reduction Process 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 into ingots or break into lumps.
Considerations
  • Precise control of temperature and reactant ratios maximizes yield and minimizes impurities (P, S).
  • Slag from aluminothermic process contains Al₂O₃; silicon process yields SiO₂‑rich slag.
  • Both methods require gas cleaning systems to meet environmental standards.
These production routes deliver FeV grades suited for steelmaking, alloy manufacturing, and emerging energy storage markets.
