# **20 Most Common Methods of Extracting Molybdenum**
### **A. Extraction from Molybdenite (MoS₂)**
1. **Flotation of Molybdenite from Ore** – Concentrates MoS₂ from gangue.
2. **Roasting of MoS₂ (2 MoS₂ + 7 O₂ → 2 MoO₃ + 4 SO₂)** – Produces molybdenum trioxide (MoO₃).
3. **Sublimation of MoO₃** – Purifies MoO₃ as a volatile oxide.
4. **Reduction of MoO₃ with Hydrogen (MoO₃ + 3 H₂ → Mo + 3 H₂O)** – Produces metallic molybdenum.
5. **Reduction with Carbon (Carbothermic Reduction)** – MoO₃ + 3 C → Mo + 3 CO.
6. **Electrolytic Reduction of MoO₃** – Laboratory or specialty high-purity method.
