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.
