I haven't seen him for a long time, and Yang Yuan looks a lot more energetic than before. Pen | fun | pavilion www. ｂｉｑｕｇｅ。 ｉｎｆｏ

On the one hand, it is manifested in his complexion, and on the other hand, it is specifically manifested in the color of his skin.

Although he is the CEO of the branch, the nature of his work and the persistence of the technician make it impossible for him to stay in the office as a white-collar worker all the time, but often have to go to the mines in Mindanao and Madagascar. Because of this, his complexion looks much darker than before.

The matter of his ex-girlfriend Sophie hit him hard, but now, he has not been crushed because of this, but has regained his strength and climbed to a new height in his career and ability.

After meeting old friends, after a pleasantry, Yang Yuan didn't talk nonsense, immediately turned around and took out a stack of reports from the office, and chatted about work.

"Assay results from the ore samples are in. ”

"The results are quite amazing! In addition to the main iron and siliceous components, we have also found an astonishing reserve of perovskite in the inner part of the asteroid! And the taste is terrifying!"

"We've picked up a treasure! This mining and smelting must be handed over to our department, we have the equipment and the technology! The specific data is here, I can't say, you can see for yourself!"

When he spoke, Yang Yuan looked excited, and he almost threw his fist excitedly. Jiang Chen could clearly feel that his mood now was even more excited than when Jiang Chen handed over the exclusive mining rights of Mindanao minerals to him.

"Don't worry, the projects related to minerals are all yours, and you can't run. ”

Jiang Chen took the report in his hand with a smile and flipped through it casually, the expression on his face was also slightly moved.

The first is an overview of the Bennu asteroid, which is based on data measured by the Applied Cosmodrome. With a diameter of about 500 meters and a volume of about 36.8 million cubic meters, the asteroid is about 4.5 times denser than water, or 4.5 tons per cubic meter, and has a terrifying mass of 165 million tons, according to its average density determined by spectrometry.

Turned to the most critical part of mineral reserves.

According to the identification of ore samples and various backhaul data by Future Mining, the iron ore reserves of this asteroid are more than 40 million tons, and the taste has reached an astonishing 80!

This is an impossible number on the earth, because it means that part of the iron will exist in the form of iron elemental! The oxidizing environment on the earth cannot give birth to such mineral deposits, and almost all the iron in the earth's crust exists in nature in the form of oxides.

But space can.

The 40 million tons of iron ore will be able to smelt more than 30 million tons of steel at ultra-low smelting costs. Not only is it enough to maintain the consumption of industrial parks on Anga Island and Singapore and Malaysia Special Economic Zone for several years, but it can also export to the international market on a large scale to earn foreign exchange!

Although the value of iron ore is high, compared to the core of titanium ore, it can only be regarded as a drizzle.

High-performance titanium alloys and titanium matrix composites have the characteristics of high specific strength, high corrosion resistance, high durability and low weight that cannot be matched by other metals. However, the Star Ring Trade does not hold much titanium ore, and apart from the wreckage recovered from the end times, most of the exterior structures of Star Ring City are made of high-strength aluminum alloys.

As we all know, perovskite is quite rich in surface reserves, which can only be regarded as rare metals rather than precious metals, but titanium alloys are quite rare. There are two main difficulties hindering the development of titanium alloy technology, one is the smelting of titanium alloy, and the other is the processing of titanium alloy.

The first is smelting, aside from the dozens of complex processing processes, because titanium is chemically quite active at high temperatures, and after the titanium ore is processed into titanium sponge, it has to be smelted once or twice in a vacuum electric arc furnace to produce high-purity titanium ingots!

Because of the complex production conditions, the cost naturally goes up.

It is precisely for this reason that the price of perovskite varies greatly according to the level of taste. Fewer impurities mean less smelting difficulty, and too many impurities don't even have the value of processing. However, in general, the price of perovskite is still around 1,000 yuan, and after processing into titanium ingots, the price will soar.

Another is processing. It is useless to make titanium ingots alone, and it is even more technically difficult to process titanium ingots into tubes, plates, screws, bearings, and even aero engines.

Up to now, it has passed the welding technology of Maozi and the titanium alloy of the United States. Due to Maozi's good titanium alloy welding technology, the reserves of titanium ore on Siberia are also very high, and the wealthy old Maozi even built several nuclear submarines out of titanium alloy, that is, the legendary Alpha-class attack nuclear submarine has been full of controversy from construction to final service!

Because the cost of titanium alloy production and processing is extremely high, some people jokingly call it "goldfish".

It was only in the strange era of the Cold War that such an absurd and powerful weapon could be born.

But now, close to 30 million tons of high-grade titanium ore has given Jiang Chen a chance to be a complete "local tyrant". Not to mention the submarine with a titanium alloy shell, even if the aluminum alloy material of the entire space elevator is replaced with a standard titanium alloy, it is more than enough!

The titanium ore found on the Bennu asteroid is not only rich in reserves, but also the key is that the taste is extremely high, and even naturally occurring titanium elements have been found in the ore samples! The smelting cost is far cheaper than the titanium ore produced by any titanium ore on the earth, and even the rich ore in the cold region of Siberia is not comparable to this!

Just for the 30 million tons of high-grade titanium ore, Jiang Chen also had to firmly grasp this asteroid in his hands.

"The smelting of the ore will be handed over to you, and the second electric ray P-1 Future Human Heavy Labor Union will complete production as soon as possible, and it will be delivered to the future mining port in Star Ring City next month. Your side should also train qualified pilots as soon as possible, the production of the Bennu asteroid must be stepped up, especially the titanium ore on it, which is very important to our space colonization plan!" Returning the report to Yang Yuan's hand, Jiang Chen immediately ordered the task to continue.

Hearing Jiang Chen's words, Yang Yuan grinned and patted his chest to pack the ticket.

"You can rest assured that space mining is the strategic development direction of our future human mining! Several mining experts in our company have been training at the astronaut training base on Anga Island for almost half a year. It won't be long before you can pass the P-1 driving license for electric rays. ”

Hearing this, Jiang Chen also smiled and nodded.

The electric ray P-1, which is now under construction on the Bennu asteroid, is mined by the future man, but the pilot is the pilot who rents the ring trade. The main training is the A-1 attack type and the C-1 transport type. Let the person who drives the tank go to the mining truck, and the mining efficiency will definitely not be high, this is the reason.

Today he came to the future mining headquarters for two things, and now one of them has been completed, and there is still one last thing left.

"There's one more thing I'll ask you. ”

"Some time ago, the design of the external ore processing unit was completed, how is it being prepared now?"

(Note: Regarding the Bennu asteroid, NSAS has just sent a probe to collect samples, and it is expected to return to Earth in 2023.) No one knows what exactly the ingredients are on it, just like the water on the moon has been proven since the twentieth century, science fiction is not popular science, I will try to ensure that it is rigorous, but I can't guarantee that it is correct.
