"Brother Peng, when can I go to the sea?" Qian congcongcong asked Xiao Peng, who was sitting by the boat fishing, anxiously.

Xiao Peng took a look at him: "I have a camera there. I'll be a photographer for you whenever you want to go into the sea."

After hearing this, Qian congcongcong said incoherently: "what I said is" going to the sea "! It's the "going to the sea" of "going to the sea", not the "going to the sea" of "going down to the sea."

Xiao Peng looked indifferent: "Chinese is broad and profound...... You can wait a few more days. This ship repair for 12 days, and then came here for three days. The wind and waves are too big to go into the water. Professor Luan is crazy. Now he is chasing the progress. The "Four Seas warrior" can only accommodate three people. If Yang Meng wants to drive the submersible, Professor Luan will take another student. Where is your seat? Just wait. If you are in a hurry, go fishing with me. "

Xiaoqiu took a fishing rod: "that is, how good it is to fish now, cultivate one's mind!"

Qian congcongcong grimaced: "I have been waiting for a week."

"OK, I see. I'll arrange it for you later." Xiao Peng asked Xiaoqiu, "has the umbrella anchor been lowered?"

"Let the boss go, don't worry!" The hill nodded.

In the deep sea, the ship just can't anchor - where is the anchor cable that long? A ship can only float on the sea, and if you want to keep the boat from drifting too far, you have to use an "umbrella anchor", which can be understood as a parachute towed by a ship in the water. In this way, the resistance of the current is used to keep the ship from running too far.

"How many hours have they been down?" Xiao Peng asked.

Huang Bin looked at his watch: "three hours!"

Xiao Peng threw the fishing rod: "how can it last three hours? Oh, my God! Five hours to go! Luan Xiwu, they are scientific research madmen, they will not come back until the last minute! "

They have been to the inspection site for a week now. Every day, Yang Meng takes Professor Luan Xiwu and a student to the bottom of the sea. Xiao Peng and his students are really bored on the sea. Every day except fishing is fishing.

But fishing is boring. Fishing in the deep sea is not as full of fish as people think. Such a place can only catch fish when they have passed the school of fish. Usually, there are very few fish. Obviously, there is no shoal in these days, so Xiao Peng and his colleagues are really bored at sea.

Don't mention Qian congcongcong. Xiao Peng will be bored to death. Luan Xiwu has no good attitude.

There was a dry cough around him. Xiao Peng looked back and saw that it was Tang monk. Oh, no, Tang Sheng.

"Dry cough what? I said it wrong? Don't cough at me like a tuberculosis! If you stare at your head again, you can't get into the sea! " Xiao Peng said angrily.

Tang Sheng's head is injured, so he can't go to the sea. Every day, he can only wait on the boat for Professor Luan to take turns to go to the sea with the rest three people. He only has the eye to see. He is seriously recuperating every day. He hopes to get well soon and go to the sea early. If Xiao Peng really deprived him of the right to go to the sea, he didn't know where to cry.

Next to a man and a woman to stop, heard Xiao Peng say bad things about Professor Luan, they want to help Professor Luan speak, but who let Xiao Peng on this ship? If Xiao Peng doesn't approve them to go into the sea, they can't go down! And Xiao Peng's mood is obviously not good. Don't see, even Tang Sheng dry cough two times let him give a spurt? They'd better not be bored.

Xiao Peng returned to the cockpit, picked up the underwater walkie talkie and asked, "Mengzi, what's the discovery below?"

After a while, Yang Meng's voice came from the walkie talkie: "or manganese nodules! Except for manganese nodules, they are manganese nodules! "

"Well, you go on suffering." Xiao Peng hung the walkie talkie back to the side of the ship.

Qian congcongcong was still very interested in the sea bottom. He said excitedly, "what's new below?"

Xiao Peng shrugged: "in addition to manganese nodules is manganese nodules. Is there anything new? "

Manganese nodules are very common in the seabed. The shape is a black or black brown potato lying quietly on the bottom of the sea. When it comes to manganese nodule mining area, it's very easy to salvage it.

Where they are now is the manganese nodule mine. According to the seafloor photos taken by Professor Luan, the sea floor is dense with manganese nodules, and the patients with dense phobia will have scalp numbness after seeing it.

And Professor Luan, they are now exploring the location of this manganese nodule mining area.

Is manganese nodule good thing? Yes! But because it's too common, Xiao Peng really can't look up to it!

Tang Sheng was a little anxious after hearing this: "Mr. Xiao, don't underestimate this manganese nodule! In addition to manganese and iron, it also contains nickel, cobalt, copper, molybdenum, titanium and other 20 or 30 kinds of elements. The same is manganese nodules, because of the different substances contained in them, the value gap is very large. It's a good undersea resource. "

Qian Congcong blinked and asked curiously, "is our country short of manganese?"

Xiao Peng shook his head: "there is no shortage of this stuff. Our country's manganese content is the third in the world, almost everywhere. So I'm not interested at all. "

Qian congcongcong was also disappointed.

As a result, Tang Sheng quickly explained: "Mr. Xiao, although our country says that there are many manganese mines, there is also a large demand for manganese. Our country has developed infrastructure and needs manganese steel everywhere, including weapons production, which also needs a lot of manganese steel. Although there is no shortage of manganese ore in our country, compared with the manganese nodules in Haiti, it is a drizzle! Let me just say that. Maybe the manganese content in a manganese rich nodule mining area exceeds the total content of all manganese ores in China! This is a good stock! Moreover, there are other elements in manganese nodules. According to the different elements contained, the value of manganese nodules is also very large. Besides, manganese nodules are mainly composed of ferromanganese, which also solves the problem of iron deficiency in our country, which is a valuable mineral resourceXiao Peng shrugged: "that's right. This is a resource with low cost and large demand. But I'm really not interested

The most important function of manganese is to add it to steel to make manganese steel.

This manganese steel is also very interesting. If you add about 3% of manganese into the steel, it is called low manganese steel. The steel made in that way is brittle like glass, which will be broken with a slight knock; but if you add more than 13% manganese to make high manganese steel, the steel will become hard and tough again! Moreover, it has no magnetism, so the wear-resistant components such as rail, bridge, bucket and ball bearing of bulldozer and excavator are all made of high manganese steel. The alloy, which is made of steel, manganese and nickel together, is the raw material for making precision electrical instruments. Therefore, manganese steel is a very important alloy.

Steel manufacturing is a very rigorous and important knowledge. For example, those protagonists in travel novels can make steel products when they go back to ancient times. It's OK to have a look. Unless the protagonist is a professional steel mill engineer before crossing, he can't really do it.

Tang Sheng said: "according to our sampling investigation in this period of time, we found that the manganese nodules here are cobalt rich manganese nodules, and there are a lot of copper in them, which is a very good element combination. We are now determining whether all manganese nodules here are formed in this way

"Cobalt?" Xiao Peng blinked: "well, I understand why Professor Luan is so active."

Qian Congcong asked, "Peng, what does this mean?"

Xiao Peng explained, "our country is short of cobalt, and all this stuff is imported."

Qian Congcong asked, "what is the cobalt for?"

Xiao Peng was concise and comprehensive: "the oil of new energy vehicles" is the raw material for making batteries. However, this kind of resource distribution is too concentrated, only in a limited number of countries, of which the Congo (DRC) alone accounts for half of the world's proven reserves. We import 97% of our cobalt from the DRC. "

Qian Congcong nodded his head and said, "I know that the Chinese went to Congo (Kinshasa) to mine. I have a friend who is mining there and has made a lot of money. But it's not very good this year. "

Xiao Peng stretched out his thumb: "that should be to develop cobalt ore. this year, the price of cobalt has plummeted, so it is not very good to earn."

There are few reports on the country of DRC in Huaxia. People hear that the impression here is that it is very poor and chaotic, and there is a country called Congo Brazzaville next to it. However, what people don't know is that all the eight mining giants in China have their own industries in DRC.

This is because almost the entire territory of DRC is built on an open pit mine! Local people mining directly from the surface of the ore collection, no need to dig any mine hole!

In recent years, some bold Chinese have gone to the Democratic Republic of Congo. Many Chinese with tens of thousands of dollars or even thousands of dollars have gone to Africa, directly to the villages to buy the ores collected by the local people by hand, and then sell them to the mining and dressing smelter. The profit is calculated by more than 10 times after the turnover! A lot of people have become rich in this way. A Zhejiang businessman once entered the Democratic Republic of Congo with 150000 US dollars. Two years later, the profit reached 200 million yuan.

Of course, this is also based on the risk. The so-called "seek wealth in danger", people can only see the winners, and many of them have lost their lives.

The local security situation is relatively poor. When every Chinese arrives in the Democratic Republic of Congo, the embassy will remind them not to go to the streets alone and reduce the number of times they go out. Almost everywhere, all the factories of Huaxia enterprises are surrounded by walls, just like prison.

In fact, the price of cobalt ore was still very low ten years ago, because cobalt was originally used for manufacturing, but due to the saturation of demand, the price dropped sharply. One ton is about 200000 yuan. However, by the end of 2016, the battery of new energy vehicles began to use ternary lithium batteries, which again required a large amount of cobalt, so the price skyrocketed to 700000 tons in a year! As soon as the cobalt producing countries are profitable, they have increased their cobalt production, resulting in oversupply of supply. In addition, battery manufacturers have developed high nickel batteries to reduce the demand for cobalt. In the end, the price of cobalt plummeted again, but now it costs more than 300000 yuan per ton.

If it is really cobalt rich manganese nodules, it will attract many mining groups to come to mine, but Xiao Peng is really not interested.

The reason is nothing else: I can't see it!
