The types and distribution of copper deposits in the world are diverse, which can be divided into:
Porphyry (1), (2) the sand shale type, copper and nickel sulfide type, (3) (4) (5) copper pyrite type - type uranium - gold, natural copper type (6), (7) vein type carbonate rock type (8), (9) skarn type

[porphyry]
Banyan copper deposit is a kind of copper deposit with large grade, low availability and large-scale mechanized mining. Its ore reserves often reach several hundred million tons, and the copper grade is usually less than 1%. According to the statistics of 103 porphyry type deposits in the world, the ore quantity of each deposit can reach 550 million tons on average, and the copper grade is 0.6%.

[distribution]
Known porphyry copper deposits are found in :(1) the Pacific rim, including the south. Continental margin narrow porphyry copper belt in North America, such as Canada, nie, Bavarian family, bingham, than, especially in the United States morenci, yili, saint tower, Mexicos o connor inside, her DE la, panama, Colorado, Perus mitch base tired, Luo Foer di. Praised Mr El Chile in the Roman abramovich, QiuJi mata, lae, dida, el Salvador and el, etc., (2) the tethys porphyry copper belt, including Hungary rex, Yugoslavia MaiDanPei grams, Irans sarche meghi and maqestans chagai region deposits and so on. (3) central Asia -- Mongolia, with important deposits such as kalmarkle in eastern uzbekistan, coondag in the north of kazakhstans balkhash lake, cagan sublga in the south of erdeujian orbo in the north of central Mongolia and arunor in the east.

[sand shale type]
Sand shale type copper ore is generally referred to the strato-controlled copper ore in sedimentary rocks of different ages. The deposit is produced in a set of sedimentary rocks or sedimentary metamorphic rocks. It is one of the main industrial types of copper ore in the world, accounting for about 30% of the worlds copper reserves.

[distribution]
The deposit is widely distributed in the world, in addition to the above copper strip, and the former Soviet union more candy, jie, katz copper mine, the white pan, American western Montana extends to the southwest of bell Canada copper strip, and the copper strip of Bolivias families and so on, in recent years, great facility in Afghanistan found copper and found in Brazil salobo copper all belong to this type.
[pyrite]
Pyrite type copper deposits are those containing a large amount of pyrite and a certain amount of copper, lead and zinc which are associated with submarine volcanism.
At least 420 such deposits have been found worldwide, including Canada, the United States, the former Soviet union, Spain, Portugal, Cyprus, South Africa and Japan.

[massive sulfide ore]
This modern deposit is 21 degrees north latitude, in 1978 near the eastern Pacific ridge discovered for the first time, although a high grade of copper zinc (zinc copper 6%, 29%), but the ridge found a 970 meters long and 200 meters wide, 35 meters high, has more than 25 million tons of ore metals massive sulfide deposits, the first time reached the requirement of industrial ore deposit, the ore containing copper as high as 11%, zinc 0.8%, also contains a small amount of silver (PPM), molybdenum (0.03%) and tin (0.03%).
[distribution]
In 1982, the United States continued its investigation in the sea area of 13 degrees north latitude, and several mineral deposits were found. Recently, the excelplor ridge in the sea area around vancouver island, Canada was 1%, but this type was the most important in the former Soviet union, accounting for 30.6% of its total copper reserves. Canadas sudbury, Thompson, linek, the United States Duluth complex, the former Soviet unions beichenga, norilsk, tarnach," October ", the kambalde complex in Australia, the gothenach belt in Finland, and, of course, the supersize of our countrys jinchuan bai jia tsui.
[other types]
In addition to the above categories, as well as vein type, natural type copper, carbonate rock type skarn type, etc., they account for only 3.6% of the worlds total reserves of copper, but for different countries, these types may be important, such as the skarn type to type, is a very important industry in China, accounting for 28% of the total reserves of copper in China, so, all countries should be according to their specific geological environment, find the most economic value of quality deposit, which is high grade, size, shape, ore belt boundary obviously. The most important of these factors is the high grade. The most likely source of this high grade copper deposit will be the volcanogenic pyrite type copper deposit, stratified ore deposit, and some skarn deposits.
