🪨 Copper
Name: Copper
Type: mineral
Rock_type: igneous
Atomic_number: 29
Element_symbol: Cu
Origin_countries: Chile, Peru
Uses: electronics, infrastructure, renewable energy, wiring, plumbing
AKA: cobre
Origin & Location
The word copper is a corrupted form of a Latin word that meant “metal of Cyprus," referring to Roman copper mining on the island of Cyprus. The modern name for the element first came into use around 1530.
-
Primary source(s):
- Chile: Especially in the Atacama Desert region (e.g., Chuquicamata and Escondida mines)
- Peru: Southern highlands (e.g., Las Bambas, Cerro Verde)
-
Geological context:
Found in porphyry copper deposits, formed by hydrothermal fluids in igneous rock intrusions, particularly along tectonic plate boundaries of the Andes.
Uses
Uses may be industrial, cultural, nutritional, etc.

Essential for human nutrition
🗺️ Story of Discovery & Exploitation
-
Initial discovery:
Indigenous peoples of South America, including the Moche and Inca, used native copper for tools and ornamentation as early as 500 BCE. -
Colonial/modern extraction:
Spanish colonizers initially focused on gold and silver, but copper became significant in the 19th and 20th centuries. During the 20th century, U.S. and British companies dominated Chile’s mines. -
Modern situation:
In 1971, Chile nationalized its copper mines (e.g., CODELCO), which remains state-owned, but foreign companies still dominate parts of the supply chain. Peru has seen violent conflicts over mining expansion on Indigenous land, particularly in the Andean highlands.
⛏️ Extraction Requirements
-
Mining method(s):
- Open-pit mining (Chuquicamata is one of the world’s largest)
- Underground mining (less common)
- Smelting and acid leaching (produces toxic waste)
-
Environmental cost:
- Massive water use in arid regions
- Acid mine drainage contaminates rivers
- Tailings ponds threaten ecosystems and communities
-
Human cost:
- Displacement of indigenous communities
- Labor exploitation and union crackdowns
- Heavy metal exposure for nearby residents and miners
