Universe dominance

"Bang!"

Far away at the Tanegashima Space Center on Earth, Ichiro Yagyu had dropped several pieces of his beloved antique porcelain, but at this time, the anger in his heart was getting stronger and stronger.

He had already chosen Yunhai as the location of his lunar base, and Yunhai had long been regarded as his own, but now Li Fu's Fuyun Group had taken the lead, and the entire moon plan was completely destroyed. If it is disrupted, all subsequent related plans will have to be adjusted, and other areas will have to be selected to build their own lunar base.

"Yagyu-kun, the atmosphere has no effect now. What we have to do now is to readjust the plan and quickly build a lunar base on the moon. Otherwise, there will be fewer and fewer good places on the moon's surface. I heard that Sam The uncle is also preparing to build another lunar sub-base in the near future.”

Gomori Kouta on the side is very sensible. He knows that now is not the time for the atmosphere. Fuyun Group's strong strength in space, coupled with the help of Chinese officials, it is very simple and easy to build a base on the moon. There is no need for detailed planning like mine, and it also takes a long time.

I didn't receive any news in advance. I didn't expect that Fuyun Group would suddenly build a lunar base on the moon on a whim, and they just happened to choose Yunhai to occupy the place that Foot Pot Chicken had chosen in advance. .

"call!"

"Gomori-kun is right. Now is not the time to be angry. Our moon base plan must be implemented as soon as possible. If we don't hurry up, there will really be no place for us on the far side of the moon."

"Goshou-kun, please, please revise the plan as soon as possible and then execute it."

Yagyu Ichiro exhaled heavily, and then nodded slowly.

"Hey, other problems are not big. The key now is that for our aerospace plane, Fuyun Group's astronauts say they need to take a day off every time they go to space. As far as I know, Fuyun Group's aerospace aircraft When the Space Shuttle is at its most frequent, it can carry out hundreds of missions to and from space a day. If we want to implement the moon base plan as soon as possible, we must get rid of them. "

Gomori Kouta frowned. Every aspect of the Takatsuki is now like a clockwork machine. Everything is done in a hurry, but when it comes to the last step of going into space, the astronauts sent by the Fuyun Group Every time I procrastinate, I will always find various reasons to delay. There is no way for the anxious one.

"Tell Nishimura Jiro, no matter what method is used, whether it is money or beauties, we must deal with them. Once every two days is too little, not to mention hundreds of times a day. Now we treat them like uncles, and we can travel to and from space several times a day." Not too many times.”

Having said this, Yagyu Ichiro was very angry again. The aerospace plane he bought at a huge price actually had little to do with him. Everything must be approved by the astronauts and security personnel sent by the Fuyun Group. Before it can be executed, various things that delay time appear.

"Hey!"

…

Far away on the moon, which is more than 300,000 kilometers away, here at the Lunar Sea of ​​Clouds Base, there are more than ten large-scale "Hercules" space planes transporting massive supplies there every day. The scale of the Sea of ​​Clouds Lunar Base is getting bigger day by day. , living areas, scientific research areas, factory areas, agricultural areas, airport areas, etc., are rapidly forming one after another.

At this time, in the Yunhai Base factory area, Cao Haitao, the person in charge of the Yunhai Base, is directing the base workers to carry out lunar mining.

A very large lunar engineering vehicle. This lunar engineering vehicle is more than ten meters high. Overall, it is an enlarged version of a large excavator with a huge digging claw, which is specially used to excavate rocks, soil, etc. on the moon. wait.

In the lunar engineering vehicle, Cao Haitao, who was wearing a space suit, was connected to the virtual machine for command. Han Dafei, a huge lunar mining worker, was driving the engineering vehicle out attentively.

"Everyone, please keep up. This is our first time mining on the moon, and we will strive to successfully dig out the first pot of gold."

Following Cao Haitao's command, more than ten large lunar transport vehicles followed behind. More than ten vehicles drove on the desolate lunar surface. Their destination was a mining area only 5 kilometers away from the base.

The most valuable minerals on the moon are rare earth minerals. The same is true for Cao Haitao's goal. In fact, there are lunar basalts rich in rare earth minerals everywhere on the moon. Cao Haitao's chosen target is a large mountain range more than 200 meters high, almost The entire mountain range is made of basalt, and the rare earth content it contains is amazing. It is also a rare high-quality rare earth mine among rare earth mines and is extremely valuable.

"Brother Tao, you are a great scientist. Can you tell us what is going on with these rare earths? How are they mined from stones and soil?"

While walking and chatting along the way, Han Dafei couldn't help but ask Cao Haitao. Han Dafei was a college student who just graduated last year, but he studied a major that had nothing to do with mining.

"Rare earths are the general name for seventeen metal elements including lanthanides, scandium and yttrium in the chemical periodic table. There are currently 250 kinds of rare earth minerals in nature. The first person to discover rare earths was the Finnish chemist Gadolin, who made it from a piece of metal in 1794 The first rare earth 'element' - yttrium earth - was isolated from a heavy ore that resembles bitumen. Because there were fewer rare earth minerals discovered in the 18th century, only a small amount of water-insoluble oxides could be produced by chemical methods. Historically, it was customary to This oxide is called 'earth', hence the name rare earth."

“In general, the mining methods of rare earths can be divided into three categories, namely acid method, alkali method and chloride decomposition method. Acid method decomposition is further divided into hydrochloric acid decomposition, sulfuric acid decomposition and hydrofluoric acid decomposition method; alkali decomposition method is also divided into It is divided into sodium hydroxide decomposition or sodium hydroxide melting or soda roasting method..."

"In fact, the value of rare earths themselves is already quite high. The value of a single high-purity rare earth element is thousands or even tens of thousands of times higher. Although China exported a lot of rare earths in the past, we only exported primary products at very high prices. Instead, we have to buy high-purity rare earths from European and American countries, and we don’t know how badly they have been sheared.”

"Brother Tao, can't we extract high-purity single rare earth elements ourselves?"

"It is relatively complex and difficult to separate and extract a single pure rare earth element from the mixed rare earth compounds obtained after the decomposition of rare earth concentrates. There are two main reasons for this. One is the physical interaction between lanthanide elements. The properties and chemical properties are very similar. The radii of most rare earth ions are between two adjacent elements and are very similar. In aqueous solution, the rare earth ions have a high affinity with water and are chemically protected by hydrates. The properties are very similar and it is extremely difficult to separate and purify.”

"Second, the mixed rare earth compounds obtained after the decomposition of rare earth concentrates are accompanied by many impurity elements (such as uranium, thorium, niobium, tantalum, titanium, zirconium, iron, calcium, silicon, fluorine, phosphorus, etc.). Therefore, in In the process of separating rare earth elements, not only the separation between these dozen rare earth elements with extremely similar chemical properties must be considered, but also the separation between the impurity elements produced by the rare earth elements. "

"Does our company have the purification technology now? Brother Tao, we can't keep letting Europeans and Americans use scissors to cut our wool."

"You must have mastered it. Now it's their turn to shear their wool. Haven't you seen that we sell one aerospace plane for trillions?"

Cao Haitao also agreed very readily. It was boring on the road anyway, and chatting with each other could quickly pass the time. Along the way, everyone started to learn about rare earth mines. After chatting and chatting, they soon arrived at the mining area. here.

"Brothers, work has begun!"

Han Dafei roared through the intercom, and drove the machine to dig into the hills of the moon with his huge claws. The basalt rocks on the moon shattered one after another. He grabbed a handful of basalts, and then turned around and loaded up the basalts, soil, etc. On top of the engineering vehicle following behind.

It took less than 30 minutes for more than a dozen engineering vehicles to be fully loaded, but the hill in front of them seemed to have not changed at all. The loss of quality was simply a drop in the bucket for it.

Ten minutes later, everyone drove the lunar engineering vehicles back to the lunar base. One by one, the lunar vehicles poured all the basalt, soil, etc. onto the smelting line.

As the rotating belt rotates, the mined basalt first enters the crushing workshop, where pieces of basalt are crushed into powder, and then enters the smelting furnace to begin the separation of rare earth elements.

The rare earth ores that Cao Haitao chose here are dysprosium and terbium element rare earth ores, which are relatively valuable among rare earths. The value of these two rare earth ores has always been relatively high, especially the rare earth ores with high purity and high fineness, which are even more valuable.

A few hours later, Cao Haitao, Han Dafei and others all looked eagerly at the separation furnace. Dozens or hundreds of tons of rocks, soil, etc. were loaded in front, but the rare earth ore that was finally smelted was very little. It's pitiful, only less than a few kilograms.

"Brother Tao? This silver-white thing is rare earth?"

"Well, this is rare earth."

"Why is it only a little bit? We put hundreds of tons of basalt in, and if it comes out just a little bit, our boss will lose money to grandma's house."

"What's the point of just coming out? Do you know how much this is worth? It costs hundreds of millions. I didn't expect that the moon's rare earth mines are already so rich. No matter how much basalt you dig, you can extract so much rare earths. come out."

Looking at the final product, Cao Haitao touched his chin and was shocked by the rich rare earth minerals on the moon. You must know that the final product is a high-purity rare earth element with a very high value.

PS: Please vote for anything!

I wonder if you have seen rare earths? I grew up playing with rare earths when I was a child. The mountains near my hometown contain rare earths, and they are exploited and mined indiscriminately. The locals did not make much money, but the green mountains and green waters were completely destroyed. Alas! A long sigh, this is something Lao Niu has seen with his own eyes since he was a child. The villagers sell their mountains to outsiders for mining, but they go out to work. They are really guarding the gold and silver mountains but have been poor all their lives. It is very sad! There are too many such cases in China.
