Known Extraction Methods
Perfect 👍 — next in **periodic table order** is **Nickel (Ni, atomic number 28).**
Nickel is a **transition metal** that rarely occurs free in nature. It is primarily found in **sulfide ores (pentlandite, Ni₉S₈) and laterite ores (limonite-type NiO(OH))**. Industrial extraction involves **pyrometallurgical and hydrometallurgical methods**.
Here are the **20 most common methods of extracting Nickel**:
---
# **20 Most Common Methods of Extracting Nickel**
### **A. Pyrometallurgical / Large-Scale Methods**
1. **Smelting of Nickel Sulfide Ores (Roasting + Electric Furnace)** – Converts sulfides to matte (Ni,Fe)S.
2. **Converting Matte to Metallic Nickel** – Oxidative removal of Fe and S in converters.
3. **Mond Process (Ni + CO → Ni(CO)₄ → Ni)** – Produces high-purity nickel.
4. **Ferronickel Production via Laterite Smelting** – Nickel + Fe alloys for stainless steel.
5. **Blast Furnace Reduction of Nickel Laterites** – Historical method; now mostly electric furnace.
6. **Submerged Arc Furnace Reduction of Sulfide Ores** – Produces Ni-Fe matte.

### **B. Hydrometallurgical Methods**
7. **Pressure Acid Leaching (PAL) of Laterites** – Converts NiO/Ni(OH)₂ to Ni²⁺ solution.
8. **Heap Leaching with Sulfuric Acid** – Low-grade laterite ores.
9. **Ammoniacal Leaching of Sulfide/Nickel Matte** – Solubilizes Ni for separation.
10. **Solvent Extraction of Nickel from Leach Liquors** – Uses organophosphorus extractants.
11. **Ion Exchange Purification** – Separates Ni from Co, Cu, Fe impurities.
12. **Precipitation of Nickel Hydroxide (Ni(OH)₂)** – Intermediate before reduction.

### **C. Reduction to Metallic Nickel**
13. **Hydrogen Reduction of NiO or Ni(OH)₂** – Produces metallic nickel powder.
14. **Electrolytic Deposition from Ni²⁺ Solutions** – High-purity nickel metal production.
15. **Aluminothermic Reduction of NiO** – Small-scale or specialty lab method.
16. **Reduction of Nickel Chloride (NiCl₂) with Na/K** – Lab-scale metallothermic reduction.
17. **Magnesiothermic Reduction of NiO** – Experimental lab method.
