Process of Making Ferrovanadium from Vanadium Pentoxide

Step‑by‑Step Aluminothermic & Silicothermic Routes
Ferrovanadium (FeV) is most commonly produced by reducing vanadium pentoxide (V₂O₅)​ with a suitable reducing agent in a high‑temperature furnace. Two main industrial routes are used:

A. Aluminothermic Process (Most Common for FeV40–FeV80)

Step
Description
1. Raw material preparation
Mix V₂O₅ powder with iron oxide or steel scrap (to supply Fe) and aluminum powder (reducing agent). Add lime (CaO) as flux.
2. Charging
Place mixture in a refractory crucible or lined steel pot.
3. Ignition
Initiate reaction with a starter charge (e.g., Mg ribbon or barium peroxide). Reaction is highly exothermic (self‑sustaining).
4. Reduction reaction
Main reaction:

Vanadium metal forms and alloys with Fe in situ. |
| 5. Slag formation​ | Al₂O₃ + fluxes form a solid slag layer on top. |
| 6. Separation​ | After cooling, crush and separate FeV buttons from slag (mechanical or magnetic methods). |
| 7. Crushing & sizing​ | Produce lump or granular FeV of desired size. |
Features
  • Fast, batch process.
  • Produces higher V grades (FeV60–FeV80) but leaves Al in alloy (requires low‑Al grade control).

B. Silicothermic Process (Electric Arc Furnace Route)

Step
Description
1. Charge preparation
Mix V₂O₅ with iron scrap and ferrosilicon (FeSi75) or silicon metal as reducing agent; add lime flux.
2. Melting
Load into electric arc furnace; melt at ~1600–1800 °C.
3. Reduction reaction

Vanadium dissolves into iron melt. |
| 4. Alloying​ | V alloys with Fe to form molten FeV. |
| 5. Tapping​ | Pour molten FeV into molds; solidify. |
| 6. Crushing & sizing​ | Prepare final product. |
Features
  • Continuous or batch operation possible.
  • Lower Al impurity; easier to control carbon and silicon in FeV.
  • Preferred for FeV40–FeV50 grades for bulk steelmaking.
