• Copper: resource distribution and production

• Resource distribution

• In the Earth’s crust, the copper content is about 0.01%. Only in a few copper deposits can copper content be found at up to 3%-5%. Copper in nature often exists in compounds. Currently, the explored copper is about 0.35-0.57 billion tonnes, and porphyry copper accounts for about 76% of total explored copper.
• Resources distribution in the world is as follows:
• Area distribution: Copper ore resources are abundant in the world, and mainly distributed in North America, Latin America and central Africa.
• Country distribution: In the world, copper resources are mainly concentrated in Chile, the United States, Zambia, Russia and Peru. Chile is the country with the richest copper resources in the world, its copper metal reserves accounting for around 29% of the worldwide total. At the same time, Chile is the world's largest copper producer and exporter.
