Global Nickel Supply Chain Report

1. Mineralogy and Occurrence

Nickel ($\text{Ni}$, atomic number 28) occurs primarily in two distinct geological forms, which dictate the entire downstream industrial architecture:

• Magmatic Sulfides: Found in ultramafic rocks. The primary economic mineral is pentlandite $(\text{Fe,Ni})_9\text{S}_8$. These deposits are typically high-grade and concentrated, with major sites in the Sudbury Basin (Canada) and Norilsk (Russia).
• Laterites (Oxides): Formed by the chemical weathering of ultramafic rocks in tropical climates. These include nickeliferous limonite $(\text{Fe,Ni})\text{O}(\text{OH})$ and garnierite (hydrous nickel silicates). These are lower-grade, sprawling deposits dominant in Indonesia, the Philippines, and New Caledonia.

2. Extraction and Refining

The "thermal tax" of nickel varies by ore type:

2.1 Pyrometallurgy (Sulfide Path)

Sulfide ores are processed via froth flotation to create a concentrate, which is then smelted in furnaces to produce a nickel matte. This matte is further refined using the Sherritt-Gordon process, where hydrogen sulfide is added to remove copper, followed by solvent extraction to separate cobalt and nickel.

2.2 Hydrometallurgy (Laterite Path)

Laterites are often processed via High-Pressure Acid Leaching (HPAL), using sulfuric acid at high temperatures and pressures to dissolve the nickel from the iron-rich matrix. This is a chemically aggressive and energy-intensive process.

2.3 The Mond Process (Ultra-Purification)

For the highest purity ($>99.99\%$), the Mond process is employed. Nickel is reacted with carbon monoxide ($\text{CO}$) at $40\text{--}80\text{ }^\circ\text{C}$ to form volatile nickel tetracarbonyl $\text{Ni}(\text{CO})_4$, which is then decomposed at $230\text{ }^\circ\text{C}$ to deposit pure nickel powder.

3. Global Production and Geopolitics

As of 2024, global production is approximately $3.7\text{ million tonnes/year}$.

• Indonesia: The dominant producer ($\approx 2.2\text{M t}$), leveraging vast laterite deposits.
• Philippines, Russia, Canada, China, Australia: Secondary producers providing the bulk of the sulfide supply.
• The "Short Squeeze" (2022): The market's fragility was exposed during the Russian invasion of Ukraine, where fears of sanctions on Norilsk Nickel led to a price spike to $\approx \$100,000/\text{tonne}$, forcing the LME to suspend trading.

4. Industrial Application

• Stainless Steel ($\approx 68\%$): The primary sink, where nickel provides corrosion resistance and structural stability.
• Batteries ($\approx 4\%$): A rapidly growing sector. Nickel-oxide hydroxides serve as cathodes in Li-ion batteries for electric vehicles (EVs), where high nickel content increases energy density.
• Superalloys: Used in aerospace (e.g., the Zenith rocket engine) for stability in extreme high-pressure, high-temperature oxygen environments.
