Copper is one of the earliest ancient metals discovered by human beings. The world copper resources are mainly concentrated in Chile, the United States, Zambia, the Commonwealth of Independent States and Peru. Chile is the country with the richest copper resources in the world, accounting for about 1/4 of the world's total reserves. The smelting technology of copper is still dominated by pyrometallurgy, and modern wet smelting technology is gradually popularized. The average cost of copper smelting by internal combustion method is 1400- 1600 USD/ton, and the cost of copper smelting by wet process is 800-900 USD/ton. World copper consumption is concentrated in developed industrial countries, and the United States is the largest copper consumer, accounting for about 1/5 of the world total. Major copper exporters in the world: Chile, Zambia, Peru, Zaire, etc. The main copper importers in the world are the United States, Japan, Europe and China.
Although China is poor in copper resources, it is one of the major refined copper producers in the world. Copper production is concentrated in East China, accounting for more than 50% of the total copper production in China, and Anhui and Jiangxi provinces account for about 35%. The main copper producers are Tongling Nonferrous Metals Group Corporation, Jiangxi Copper Co., Ltd. and Yunnan Copper Co., Ltd. The main consumption areas of copper in China are concentrated in East China and South China, accounting for about 70% of the total national consumption. Compared with developed countries, the proportion of copper consumption in China's electronics, electrical industry and machinery manufacturing industry is obviously higher than that in developed countries, while the proportion of copper consumption in construction industry and transportation industry is lower than that in developed countries. China is a country short of copper resources. The self-sufficiency rate of raw materials for copper smelting is only 40%, and a large amount of copper concentrate needs to be imported every year.
