Would you like me to **make a pie chart** for this breakdown (like we did for aluminum, silicon, titanium, etc.), so you can compare vanadium’s sector balance visually?Known Methods of Extraction
Perfect 👍 — next in **periodic table order** is **Vanadium (V, atomic number 23).** Vanadium is a **transition metal** that never occurs free in nature. It is found in **vanadium-bearing magnetite, carnotite, and various ores like patronite (VS₄) and vanadinite (Pb₅(VO₄)₃Cl))**. Extraction usually involves **oxidation of the ore**, conversion to **vanadium pentoxide (V₂O₅)**, and then reduction to metal. Here are the **20 most common methods of extracting Vanadium**: --- # **20 Most Common Methods of Extracting Vanadium** ### **A. Industrial / Large-Scale Extraction** 1. **Roasting of Vanadium Ores (Carnotite, Patronite) with Sodium Carbonate + Air** – Produces sodium metavanadate (NaVO₃). 2. **Acid Leaching of Roasted Ore** – Converts sodium metavanadate to soluble vanadium salts (VO²⁺). 3. **Precipitation as Ammonium Metavanadate (NH₄VO₃)** – From acidic solution; intermediate for V₂O₅. 4. **Calcination of Ammonium Metavanadate → V₂O₅** – Produces vanadium pentoxide. 5. **Reduction of V₂O₅ with Aluminum (Aluminothermic / Thermite)** – Produces metallic vanadium. 6. **Reduction of V₂O₅ with Magnesium (Magnesiothermic)** – Laboratory and small-scale industrial. --- ### **B.
