Chapter 877 Returning to China
Lin Dong didn't think too much about Jiang Hongwei's happiness troubles.He directly asked He Dongcheng to recruit another group of people in the country, and then sent over a group of mining personnel who had previously reserved—while mining the metal Taihe gold mine at the same time, the pressure on the personnel was a bit high.

Of course, the people who asked to come this time were very positive.Because two of the employees were hit by stray bullets and went back to China to recuperate, but they were recuperating with five-figure medical expenses, bonuses and full salary!
The other injured security team members are also fully paid to rest.This time, as long as the security guards who participated in the battle, the reserve team members who took the initiative to apply, and the stretcher team members, each will be rewarded with 1 yuan, and those who perform well will get double or even three rewards!
After the news of such a high bonus reached the country, many of those who didn't come regretted it. They just wandered around the battlefield and received such good treatment. Who wouldn't want to go?Besides, in order to set an example, the Changying Group directly took a lot of photos and sent them back to the country to publicize the heroic security guards and mining personnel who participated in the war this time. Those who didn't come were very greedy!
"Mr. Lin, this is the first batch of metal powder!"

A series of mining processes were originally very water-consuming projects.Afghanistan is very short of water, especially in the area Lin Dong is looking for. It is very difficult to find a suitable water source.

Even the drinking water in the camp is found by digging wells - the Taha tribe has water, but that small water source needs to supply tens of thousands of people to drink, and it is not very rich. Fortunately, it is in a place deep underground There are underground water sources.What Lin Dong lacks here is that there is no shortage of machinery, well drilling is no problem, and the water quality is good.

But if these waters are used for mining ore dressing, it is a bit difficult.

Of course, this can't help Lin Dong. Dry mineral processing is really nothing to Lin Dong.But what is formed is not a metal block, but a metal powder.And the purity is not very high.

In practice, of course, this is enough.These metal powders will be sent back to the country, and then further processed to form metal ingots, and then sent to metallurgical plants to be processed into the required alloys for further processing.

Lin Dong looked at the metal powder sent by Xia Guangcheng. It was different from the metal ingot formed in his memory. The metal powder had a bit of silver dust, but he immediately "recognized" that this was indeed the metal called baht that he was looking for this time. !The interpretation of baht in Chinese characters is originally a very small unit of measurement, so there will be idioms that compare with each other.

However, the baht here refers to the metal that looks gray but is actually bright white, and its content on the earth is very small, which is one of the reasons why the word "baht" is named.

However, this is what makes nature amazing. Although there are very few mines of this metal anywhere else in the world, there is such a very high-quality mine here in Afghanistan.

Just like the metal rhenium mentioned above, no pure metal mines have been found in the world, but later metal rhenium was discovered in the four northern islands, and then in the South China Sea—this is what Lin Dong told Ji Bing .It should have been discovered more than ten years later.

This kind of metal baht has obvious characteristics, high temperature and high pressure resistance, corrosion resistance, forming a coating with baht on the surface of the metal, which can resist the erosion of various cosmic rays, and is an excellent space material.

Because it was a metal discovered later, it has not been used at all. If Lin Dong had not had this information in his mind, he would not have found this mine here.

In the parallel space, this mine was discovered by French geologists, but because of the geographical relationship, the mine was finally owned by Lao Mei.Huaxia still paid a high price to buy a very small part of the metal from Laomei. There are quite a lot of this kind of metal in the asteroid belt, but there is no large-scale mine found on the earth until many years later.

Of course, in this life, Lin Dong doesn't care so much. There are so many good things on this earth, and there are too many good things occupied by Lao Mei. burden!

Carloads of supplies were brought to the camp, and a considerable part of them was sent to the Taha tribe, which made the elders of the Taha tribe truly appreciate the trustworthiness of the Changying Group.

Moreover, on the second day after the Taha tribe received the road construction permit, Lin Dong began to purchase materials, invite bids for the construction team, and apply for various procedures through the Changying Group.Because it was a special case, within a month, the first truckload of materials for road construction had already arrived at the port, ready to pass the customs and start road construction!
With Huaxia's construction speed, it is conceivable that this section of hundreds of kilometers of asphalt road may not take too long to be fully connected!
Lin Dong stayed in the camp for half a year before the whole line was connected. Then he returned with the first batch of security guards and mining employees. He also returned with them about ten tons of metal that had already undergone preliminary processing. Baht powder.

According to Lin Dong's calculations, these rough-processed metal bahts can eventually yield about five tons of metal bahts.But even these five tons, for now, are enough for the Changying Group to use for more than ten years—the most important function of the baht is to process it into an alloy and then apply it to a spacecraft.Pure metals can't fully reflect its role.

In the operation workshop of Tengjiao Group, Xu Xiaofeng looked depressed: "Obviously, the data has been tested in the laboratory, but when it comes to the simulation experiment stage, it can't resist radiation and high temperature, and the existing materials have almost been tested. , do we have to wait until Boss Lin comes back?"

Now, under the guidance of Liu Zongyi, he has successfully completed the engine manufacturing of a small aircraft, passed the verification, and successfully applied it to a domestically produced small aircraft.

But Xu Xiaofeng is obviously not satisfied. Now that Changying Group has given him such a big support, he has a stronger idea about researching space engines.

However, although the current space engine is not a particularly sci-fi technology, it is very difficult to find engine materials that require high temperature, high pressure, corrosion resistance, and the ability to freely shuttle back and forth in space.

Xu Xiaofeng has experimented with a lot of materials, and there will always be problems of one kind or another.

Space engines are really not that easy to research!

Now Huaxia, Laomei, and Laomaozi all have corresponding technologies, but the level of secrecy of that technology is equivalent to the country's core secrets, and from Xu Xiaofeng's point of view, these technologies are not perfect, and they are only used in large-scale detectors, aerospace Airplanes and space stations do not meet his requirements for the technology applied to aerospace aircraft.

You have to keep working hard!
