The main types of copper deposits in the world include porphyry type, sedimentary rock type layered type, magmatic sulfide type, volcanic massive sulfide type, iron oxide copper-gold type, skarn type, etc., each accounting for 69.0% of the world's total resource reserves. %, 11.8%, 5.1%, 4.9%, 4.7%, 2.2%, the total is 97.7%.

Porphyry copper deposits are the most important copper resources in the world, and the associated gold, molybdenum or zinc also have great economic value. Ultra-large (more than 5 million tons) porphyry copper deposits are concentrated in the Pacific Rim mineralization domain (Chile, Peru, the United States, Panama, Indonesia, the Philippines, Papua New Guinea, etc.), the Tethys-Himalayan mineralization domain (China, Pakistan, etc.) and the ancient Asian mineralization domain (Mongolia, Kazakhstan, etc.), the Pacific Rim mineralization domain is especially concentrated in the South American Andes mineralization belt.

Typical magmatic sulfide deposits include the Norilsk-Tarnakh nickel-copper mine in Russia, the Duluth copper-nickel mine in the United States, the Shoreberry nickel-copper-platinum group element deposit in Canada, and the Jinchuan copper-nickel mine in Gansu, China, etc. Typical volcanic massive sulfide deposits include the Nevis-Corbo zinc-copper deposit in Portugal, and typical iron oxide copper-gold deposits include the Australian Olympic Dam copper-uranium-gold-rare earth-iron deposit, etc., sika Typical rock-type deposits include the Pumpkin Valley copper mine in the United States and the Dongguashan copper mine in Tongling, Anhui, China.

Copper is mined in more than 50 countries around the world. In addition to the five countries with output exceeding one million tons, Australia, Zambia, Russia, Mexico, Canada, Kazakhstan, Indonesia, Poland, etc. are also important copper producers. The output of the above 13 countries accounts for 86.2% of the world. National Copper of Chile, Glencore of Switzerland, BHP Billiton of Australia, Freeport-McMoRan of the United States, Southern Copper of the United States, First Quantum Mining of Canada, Polish Copper Group, Rio Tinto of the United Kingdom, Antofagasta of Chile, Anglo-American Resources and other 10 major companies accounted for 45% of global copper production in 2020.

The main exporting countries of copper concentrate are Chile, the United States, Indonesia, Canada, Brazil, Australia, etc.; the main importing countries are China, Japan, India, South Korea, Germany, Spain, Philippines, Bulgaria, Brazil and Sweden. Imports from these 10 countries The volume accounts for more than 80% of global imports. The main exporting countries of refined copper include Chile, Zambia, India, Peru, Japan, Australia, Russia, Poland, etc. The main importing countries include China, Germany, the United States, Italy, etc. The main countries in the global copper trade are the United States, the United Kingdom, France, Germany, Italy, Japan and China. Germany and Japan are net exporters, and the United States and China are net i
