Known Extraction Methods
Perfect 👍 — next in **periodic table order** is **Iron (Fe, atomic number 26).**
Iron is a **transition metal** and one of the most abundant metals in the Earth’s crust. It does **not occur free** naturally, except in some meteorites. Iron is mainly extracted from **iron ores** such as **hematite (Fe₂O₃), magnetite (Fe₃O₄), limonite (FeO(OH)),** and **siderite (FeCO₃)**. Extraction focuses on **reduction of iron oxides**.
Here are the **20 most common methods of extracting Iron**:

# **20 Most Common Methods of Extracting Iron**
### **A. Industrial / Large-Scale Extraction**
1. **Blast Furnace Reduction (Fe₂O₃ + C → Fe + CO)** – Main industrial method.
2. **Direct Reduced Iron (DRI) / Sponge Iron Process** – Uses natural gas or coal to reduce iron oxides at lower temperatures.
3. **Open Hearth Process (Historic, Pig Iron → Steel)** – Rare today.
4. **Bessemer Process (Historic Steel Conversion)** – Converts pig iron to steel; not primary extraction.
5. **Electric Arc Furnace Smelting of Scrap or Ore** – Used for steelmaking; minor iron extraction.
6. **Carbothermic Reduction of Iron Ore (Fe₂O₃ + C → Fe)** – Basis for blast furnace chemistry.

### **B. Chemical / Laboratory Methods**
7. **Reduction of Iron Oxides with Hydrogen Gas (Fe₂O₃ + H₂ → Fe + H₂O)** – Laboratory or DRI route.
8. **Aluminothermic Reduction of Fe₂O₃ (Fe₂O₃ + 2Al → 2Fe + Al₂O₃)** – Thermite process; specialty applications.
9. **Reduction of FeCl₃ with Alkali Metals (Na/K)** – Laboratory preparation of iron metal.
10. **Electrolytic Reduction of Iron Salts** – Lab-scale electrolysis of Fe²⁺/Fe³⁺ solutions.
11. **Reduction of FeO/Fe₃O₄ with Carbon Monoxide** – Industrial intermediate step in blast furnace.
12. **Reduction of Iron Carbonates (FeCO₃) with Heat + Carbon** – Produces Fe and CO₂; minor lab method.
