Magnetic separation process

PTMS MAGNETIC SEPARATOR

how to separate two magnets？

In the past, when people talked about the scale of mineral deposits, they often said that China has no world-class large mines, especially copper mines. China’s copper resource consumption accounts for 0% of global consumption, and economic exploitation accounts for only 4% of the world. High in gold, copper raw materials are in the hands of mining oligarchs, and the right to speak in the Chinese market is weak and pitiful, and it is everywhere.

First, a few companies control about 70% of global production

According to statistics, China's copper mines have identified 96.96 million tons of resources, accounting for 4.6% of the world's proven copper resources. The economically exploitable amount accounts for 4% of the world's economically exploitable volume. The global copper mines are mainly concentrated in Chile, Australia and Peru, accounting for 53% of the world's reserves.

As a big copper consumer, China accounts for about 50% of the world's consumption. With limited domestic supply, it can only hope to import.

The world copper raw material industry is an oligopoly. Australia's BHP Billiton, the US Freeport McMullen Copper and Gold Company, Anglo American, the US copper giant Phelps Dodge, Chile's state-owned copper companies and Rio Tinto control a global output of around 70% The market pricing discourse rights are also in the hands of these industry oligarchs.

The three major domestic giants, Jiangxi Copper, Tongling Nonferrous and Jinchuan Group, are mainly smelting and processing, with poor resource occupancy and high dependence on raw materials. Among them, Jiangxi Copper has the highest self-sufficiency rate, but it is less than 20%.

Second, China's own world-class super copper mine

If you are behind, you will be beaten. If you don’t have the resources, you will be slaughtered, return to the theme, and face doubts. Does China have its own world-class mines and even super copper mines? The answer is yes.

The world's widely recognized standards are such that small scale (copper metal resources and reserves less than 1 million tons); medium scale (copper metal resources and reserves of 1 million to 5 million tons); large scale (copper metal resources and reserves of 5-20 million Tons); super scale (copper metal resources and reserves above 20 million tons).

Before 2016, there were only 25 10,000-ton mines in the world. At present, there are 26 world-class super copper mines (copper metal resources and reserves above 20 million tons), accounting for 1.53% of the total global projects, but the reserves are It accounts for 38.35% of the world's total reserves. The extra one is China's Doron Mine, the world's 26th world-class super copper mine.

At the end of 2016, the amount of copper metal discovered by Chinalco in the Duolong mining area has reached 13.492 million tons. In addition, Sichuan Hongda Company has discovered more than 7 million copper metals in the Duolong mining area. Ton. The total copper metal content of the entire Doron Mine has exceeded 20 million tons, becoming the 26th member of the world-class super copper ore concentration area (mine field) club. As the exploration of the deep side of the ore body and other exploration rights areas continues, the ranking of the Doron Mines in the world-class super copper mine will continue to climb.

In fact, it can be seen from the 26 super copper mines in the world that there are more than one super copper mine in China. In addition to the domestic multi-long mining area, there is also a copper mine, which is the Kamo copper mine of Zijin.

In October 2016, Zijin Mining announced that it had discovered 9.4 million tons of copper resources in the Kakula section of the Kamoa copper mine in the Congo (Golden) copper mine. So far, the overall copper resource reserves of kamoa have risen to 33.4 million tons. This reserve is equivalent to one-third of China's current copper resource reserves, and the kamoa copper mine has thus become the largest copper mine discovered on the African continent. As Zijin Mining beneficially holds approximately 54.4% of the equity interest in kamoa Holdings, it enjoys approximately 17 million tons of copper resources by equity, making it the largest holder of the mine.

Zijin's Kamoa copper mine in Africa and the multi-long mining area of ​​Chinalco and HTC will effectively alleviate the crisis of China's copper mining materials and will also increase China's pricing power in the copper sector. However, we must also realize that only these two are not enough.

Among the only 26 super copper mines in the world, Australia and Chile, as big copper reserves, participated in the development of 8 and 7 copper mines respectively. However, as a small resource country, Japan, through shares, holdings and cooperation with giants, Participated in the development of six super copper mines, some copper mines, Japanese raw material pricing power is far greater than China, let people ponder!

Third, China's top ten copper mines

There are six of China's top ten copper mines. Tibet is also China's most important copper base in the future. However, Tibet is located on the plateau, and its ecosystem is fragile. Once it is extremely difficult to recover, development should be cautious.

Fourth, China's existing seven major copper mines

Jiangxi Copper Base

Jiangxi Copper Mine is rich in capital, ranking first in the country. The proven copper industry reserves account for one-third of the country's copper industry reserves, and it is the largest base for China's copper industry. Now it has “six mines and two factories”, namely Dexing Copper Mine, Yongping Copper Mine, Wushan Copper Mine, Dongxiang Copper Mine, Chengmenshan Copper Mine, Yinshan Lead-Zinc and Copper Mine, Guixi Smelter and Shanghai Smelter. The six large and medium-sized mines have a proven total copper reserves of 13.87 million tons. The Dexing Copper Mine is an ultra-large copper (molybdenum) ore field and one of the largest mines in Asia.
