The Andes, the world's longest continental mountain range (~7,000 km), host some of Earth's richest mineral deposits. Key resources:
| Mineral | Key Countries | Global Significance | Primary Uses |
|---|---|---|---|
| Copper | Chile (#1), Peru (#2) | Andes = ~40% world production | Wiring, plumbing, electronics, renewable tech |
| Silver | Peru (#2), Bolivia, Chile | Andes = major global source | Jewelry, solar panels, electronics, investment |
| Gold | Peru (#6-7), Colombia, Chile | Significant contributor | Jewelry, reserves, electronics, dentistry |
| Iron Ore | Chile, Peru, Argentina | Major regional producer | Steel production |
| Lithium | Chile (Salar de Atacama), Argentina, Bolivia ("Lithium Triangle") | ~50% world reserves | EV batteries, grid storage, electronics |
| Molybdenum | Chile, Peru | Top producers | Steel alloys, catalysts, lubricants |
| Zinc / Lead | Peru, Bolivia, Argentina | Major global share | Galvanizing, batteries, alloys |
| Uranium | Argentina, Peru | Emerging | Nuclear fuel |
Subduction of Nazca Plate under South American Plate → massive magmatic arcs, hydrothermal systems, porphyry copper-gold, epithermal silver-gold, salar brines (lithium).
The Andes are indispensable to the global green energy transition — especially copper and lithium.
