Today, the world's proven copper accountants account for about 350-570 million tons, of which porphyry copper accounts for 76% of all accountants. According to geographical distribution, there are five regions with the most abundant copper deposits in the world: (1) the Western foot of the Andes Mountains in Pilu and Chile in South America; (2) the Rocky and Great Hades Valley in the western United States; (3) Congo and Africa. Zambia; (4) Republic of Kazakhstan; (5) Central and Eastern Canada. From the point of view of national distribution, the world's copper capital mainly converges in intelligence, the United States, Zambia, CIS and Peru. Among them, Chile is the country with the most abundant copper capital in the world, with proven copper reserves of 150 million tons, accounting for 1/4 of the world's reserves. The proven copper reserves of the United States are 91 million tons, ranking second in the world, Zambia and Central Asia. China's copper reserves are the third and fourth largest in the world. The world's copper ore production mainly converges in North America, the west coast of South America, Africa and CIS countries. In addition to the above regions and countries, there are also some prosperous countries in the East. The United States is the world's largest producer of copper. The output of refined copper ranks first in the world. In 1992, the United States produced about 2.16 million tons of refined copper, accounting for about 20% of the world's total production. Arizona, Utah, New Mexico and Texas in the West and northeast of the United States are the most important copper-producing regions in the United States, accounting for more than three-quarters of the world's production. In 1992, most of Chile's copper production was imported. It is the largest importer of copper in the world. According to materials, Chile is also one of the lowest copper production costs in the world. Copper production in the former Soviet Union originally ranked second in the world. Later, due to political turmoil, production fell to third place. Chile also had one of the lowest copper production costs in the world in 1992. Copper production in the former Soviet Union originally ranked second in the world. Later, due to political turmoil, copper production fell to third in the world. 1992. The output of refined copper in CIS countries is about 1.1 million tons. The CIS countries are basically self-sufficient in producing refined copper materials. Japan is an important producer of refined copper and the largest importer of copper concentrates. In 1992, Japan produced 116,000 tons of refined copper in three chapters of the statute, second only to the United States and the Commonwealth of Independent States, ranking fourth in the world. Zambia and Zaire are important copper producers in central Africa. Zambia produced about 460,000 tons of refined copper in 1992, and Zaire produced 130,000 tons of refined copper in 1992. Germany and Belgium are producers of refined copper using imported copper concentrates and crude copper smelting. The output of refined copper in Germany was about 560,000 tons in 1992, and that in Belgium was about 320,000 tons. Peru, Canada, Australia, Papua New Guinea, Poland and the former Yugoslavia are also important producers of copper. China is also an important producer of refined copper. In 1992, the output of refined copper reached a high level. 640.2 million tons, because of our country's inadequate copper capital premise, affecting the growth of copper concentrate production, a large number of copper concentrates and crude copper materials need to be imported every year. Annotation of archaeological events on copper production, people began to excavate open-pit copper mines from prehistoric times, and use copper to make original weapons. Objects and other appliances. However, for a long time, due to the original copper smelting method, copper production has been very low. In the 17th century, the contemporary copper smelting method will show a clear increase in copper production in the future. In 1928, the world's output of refined copper was 1.67 million tons. After the war, the world's elite industry grew rapidly, in 1950. The output of refined copper in the world is only 3.15 million tons. In 1992, it reached about 11 million tons in France, increasing nearly twice and a half. The growth rate of copper production in different years is different. In 50 years, the growth rate of copper production increased by 4.7% annually, in 60 years, by 4.2% annually, and in 70 years, by 2.07% annually. Since 1980, it has fallen further to 1.5%. That is to say, copper production is increasing in general trend, but the growth rate is accelerating.World refined copper production in 1982-1992 was separated into (unit: 10,000 tons): 941.85, 967.19, 954.51, 971.50, 986.21, 1015.99, 1043.27, 1079.23, 1080.83, 1060.59, 1100. From the point of view of regional distribution, the production of copper concentrates is important in the United States, Chile, CIS, Canada, Zambia, Zaire, Peru, Poland and other countries. These countries account for 67% of the world's total copper concentrate production; the production of copper concentrate converges in the United States, CIS, Japan, Chile, Zambia; Canada, Germany, Belgium and other countries, their copper concentrate production accounts for about 71% of the world's total. In 1992, the total output of refined copper in the world was 20%. Chile ranks first in the world, producing 133.29% of 10.9% of the world's total output, accounting for 12.1% of the world's total output. Japan ranks third in the world; its output is 1.16 million tons, accounting for about 5.1% of the world's total output. It ranks fifth in the world. These five countries account for about 60% of the world's total output. Copper has good electrical conductivity, second only to silver, 1.6 times as much as aluminum, and 1.8 times as much heat conductivity as silver. Copper has good ductility. Pure copper can be drawn into very thin copper wire and made into very thin copper foil. Copper can also decompose with metallization of tin, zinc, nickel and other alloys with different characteristics. Some of these alloys have good wear resistance, forging property, machine property and corrosion resistance. Copper is widely used in industry because of its excellent properties. Electrical industry is an important industry expenditure Department of copper. Construction, industry, machinery and transportation departments also consume a large amount of copper. Copper has good corrosion resistance and thermal conductivity. Therefore, it is an indispensable material for automobiles, generators, batteries, fans and refrigeration equipment. Copper is also widely used in the manufacture of communication equipment such as telephone, telegraph, television and communication satellite. Since 1980, the world's copper consumption has been separated into 904.67, 910.712, 994.41, 964.39, 1007.51, 1041336, 1053.02, 1098.82, 1079.44, 1071.40, 1073.13 (unit: 10,000 tons). From a national point of view, copper consumption is most important in the booming industrialized countries. The United States is the largest copper consumer in the world. Each year spends about one fifth of the world's copper consumption. In 1992, the world spent an estimated 10.73 million tons of refined copper. Among them, the United States is about 2.16 million tons, accounting for about 20.1%; the CIS country is about 850,000 tons, accounting for about 7.9%; Japan is about 1.45 million tons, accounting for 13.5%; Germany and France are about 1.43 million tons and 370,000 tons separated; Korea's copper expenditure reaches 345,000 tons, Taiwan's copper expenditure is about 42,000 tons. China's copper expenditure in 1992 is estimated to be 900,000 tons, which is only lower than that of the United States, Soviet Union, Japan and Germany. Fifth in the world. The important consumption departments of copper are electrical, machinery, transportation, construction, metallurgy, chemical industry and so on. Among them, the electrical industry spends the most copper. According to statistics, in the mid-1980s of the United States, Japan and Western Europe, 47.8% of the copper expenditure was spent by the electric industry, 19.5% by the machine-making industry, 15.8% by the construction industry, 8.8% by the transport vehicles, and 8% by the others. In terms of similar caliber, the copper expenditure environment in China is 55.2% by electronic and electrical products, 23.8% by the machine-making industry, 3.3% by the construction industry, 3.3% by the transport vehicles and 3.3% by the transport vehicles. By comparison, the proportion of copper spent in the electronics, electrical and machine manufacturing industries in China is significantly higher than that in the booming countries, while the proportion of copper spent on building and transporting vehicles is much lower than that in the booming countries. With the growth of construction industry and automobile industry, the distribution of copper expenditure in China is expected to change. Important importers of copper are Chile, Zambia, Peru, Zaire, Australia and Canada. Chile is the country with the most abundant copper capital in the world and is also the world's famous copper producer and the world's largest copper importer. Most of the copper ores and copper produced are supplied for import. In 1982, the import volume reached 807,000 tons, which was imported to the United States, Britain, Japan and other countries. Zambia's copper mine accountants ranked second in the world.Important exports to the European Community, the United States, Japan and other countries, but also to China. Peru's copper deposits have been proved to be the fourth largest in the world and the seventh largest in annual exploitation. Zaire is one of the world's famous copper importers. Most of the copper ores produced in the world supply imports. Important exports to Western Europe, Japan and the United States. Australia is also one of the world's famous importers of copper. In 1982, the world produced 185,000 tons of refined copper. One fourth of these supplies are imported and exported to Japan and the United States. Canada is the country with the largest imports of copper ore in the booming country. In 1982, the world produced 312,000 tons of refined copper, and imports accounted for 70% of the total production. Importing countries of copper include the United States, Japan, the European Community and other thriving countries. The United States ranks first in the world in copper mining and smelting. Its copper output in 1982 was 1.224 million tons, ranking the first in the world. However, it is still not satisfied with the domestic needs. In the same year, 285,000 tons were imported from foreign countries, nearly one fifth of its output. Japan is also a major lead-producing country in the world. In 1982, it produced 1.076 million tons of copper and imported 296,000 tons in the same year. The output of copper in the European Community countries was relatively low. It was the most important import area of copper in the world. In 1982, it imported 423,000 tons of copper from West Germany, ranking first in the world, and 368,000 tons from France, ranking second. In addition, it imported 256,000 tons from Britain, 319,000 tons from Italy, and Belgium and Luxembourg. The import volume of copper concentrate is estimated to be 340,000 tons in 1992, and the import volume of copper and alloy is 491,400 tons, which are all the highest in history. Because most of the copper imported from China comes from metal exchanges, the copper price of metal exchanges is increasing. Money turbulence has a greater impact.
