Perfect 👍 — next in **periodic table order** is **Niobium (Nb, atomic number 41).** Niobium is a **transition metal** that does **not occur free** in nature. It is primarily obtained from **columbite ((Fe, Mn)Nb₂O₆) and pyrochlore ((Na,Ca)₂Nb₂O₆(OH,F))**. Industrial extraction involves **conversion to niobium pentoxide (Nb₂O₅)** followed by **reduction to metallic niobium**. Here are the **20 most common methods of extracting Niobium**: --- # **20 Most Common Methods of Extracting Niobium** ### **A. Extraction from Niobium Minerals** 1. **Acid Digestion of Columbite or Pyrochlore (H₂SO₄ or HCl)** – Produces soluble Nb salts. 2. **Alkaline Fusion of Pyrochlore (NaOH Fusion)** – Converts Nb₂O₅ to soluble sodium niobate. 3. **Leaching with Hydrofluoric Acid (HF)** – Dissolves niobium oxides for further processing. 4. **Precipitation as Ammonium Niobate (NH₄NbO₃)** – Intermediate purification step. 5. **Conversion of NH₄NbO₃ → Nb₂O₅ by Calcination** – Produces niobium pentoxide. 6. **Solvent Extraction of Niobium from Leach Solutions** – Using organophosphorus extractants. --- ### **B. Reduction to Metallic Niobium** 7. **Aluminothermic Reduction of Nb₂O₅ → Nb + Al₂O₃** – Laboratory or small-scale industrial method. 8. **Magnesiothermic Reduction of Nb₂O₅ → Nb + MgO** – Laboratory or experimental method. 9. **Reduction of NbCl₅ with Sodium (Na)** – Produces metallic niobium. 10. **Electrolytic Reduction of Molten Nb Compounds** – Produces high-purity niobium metal. 11. **Vacuum Distillation / Refining of Nb Metal** – Purification step. 12. **Carbothermic Reduction of Nb₂O₅ (Nb₂O₅ + C → Nb + CO/CO₂)** – Experimental or specialty method. --- ### **C.
