Hand rubbing nuclear fusion live in the wilderness

Chapter 379 World Class Rare Earth Mine
It took more than two days to complete the smelting of the first pit liquid.

After cutting off the power supply of the aircraft, Han Yuan took out the cathode plate deposited in the ore liquid.

When the water droplets on it flowed clean, the audience in the live broadcast room could clearly see that the cathode plate had uneven rare metal attached to it, reflecting a silvery white metal light.

[Also, it's really refined! ! ! 】

[The anchor is awesome! 】

【Amazing, my brother, this is a brand new rare metal smelting method, right?Maybe we can steal a lesson? 】

[It’s fine to learn it secretly, we are honest learners[]~(￣▽￣)~*]

【What is this? 】

[Rare metals! 】

[Isn't this nonsense upstairs?Everyone knows that it is a rare metal, but there are so many rare metals, which one is the question? 】

[Silver white, rare metals are basically silver white. 】

[First discharge yttrium (gray black), indium (silver-white with blue), germanium (silver-gray), gallium (gray-blue), tantalum (gray), strontium (silver-white with yellow), and then from the previous anchor's introduction to the mine Look, it's a piece of 'ytterbium'! 】

[I'm stupid, is the upstairs so awesome?Do you specialize in rare metals? 】

[Amazing, so many things can be analyzed just by color. 】

[I'm afraid it's not a lie, is it? 】

Han Yuan first checked the rare metals deposited on the cathode plate, looked up and saw the barrage on the virtual screen, and said with a smile:

"A certain classmate's analysis is very good. This is indeed a 'ytterbium' plate, which is a kind of heavy and rare metal."

"For this cathode plate, the rare metal 'ytterbium' attached to it weighs about ten catties."

"I am already very satisfied that so much metal ytterbium can be smelted out of a pit of ore liquid."

Ten catties of metal ytterbium, this is only smelted from the first pit of ore liquid, and there are still many ore liquids waiting to be smelted.

Won just calculated in his mind that if all the collected rare earths are extracted, the total amount of rare metal 'ytterbium' should be about [-] kilograms.

This amount is already exaggerated, after all, he only collected three tons of ion-adsorbed rare earths in total.

Moreover, besides 'ytterbium', the rare metals contained in this weathering crust elution-type rare earth ore also include strontium, yttrium and other heavy rare metals.

There are also a lot of other heavy and rare metals.

Even if these rare earths only contain 'ytterbium', three tons of rare earths can produce 150 kilograms of ytterbium, which is also a rich ore.

It should be known that 'ytterbium' mainly exists in xenotime, black rare gold ore and monazite, and the content of monazite is relatively high, about 0.03%.

This means that only 0.03 tons of ytterbium can be produced from [-] tons of monazite, which is [-] kilograms.

The weathered crust elution-type rare earth mine discovered in Sichuan can produce 1.8 kilograms of ytterbium on average from about [-] tons.

In contrast, it can be said that the enrichment of rare metal ions in this rare earth mine is simply unimaginable, close to a hundred times that of ordinary rare metal mines.

In addition, the rare metal ions in this weathering crust elution-type rare earth mine are not only high in enrichment, but more importantly, this rare earth mine in Chuandu is very large.

According to the data sent back from the metal mineral detector, Han Yuan knew that the rare earth mine hidden deep in the mountain covered an area of ​​more than 500 square meters with ion-adsorbed rare earth, and its size was almost a square of 500 meters by [-] meters.

In addition to the astonishing area, what is even more astonishing is that this weathered crust elution-type rare earth mine contains a total of 1.13 million tons of ion-adsorbed rare earths, which can be said to be a world-class rare earth mine.

Although in terms of scale, the weathered crust elution-type rare earth mine in Sichuan is far inferior to the rare earth mine in the Baiyun Obo area of ​​Inner Mongolia, where more than 3 million tons of rare earth mines have been proven.

But the comparison between rare earth mines is not only about the size, but also about how many rare metals can be smelted from them, and also about the value of the rare metals.

And if you compare it from this aspect, the weathered crust leaching type rare earth mine in Chuandu can be said to be better than the Baiyun Obo mining area.

It is a heavy rare metal rare earth mine, and the value of medium rare metals contained in it is greater than that of light rare metals.

It can be said that there is such a rare earth mine, judging from the stock of the rare metal 'ytterbium' contained in it, as long as Huaguo develops it, it can supply the world's demand for 'ytterbium' within 20 years and completely monopolize this area.

The value of this rare earth mine can be described as SSS strategic level.

After disposing of the 'ytterbium' on the cathode plate, Han Yuan then lifted up other cathode plates with rare metals in the pit one by one.

The final weighing results came out, and a total of 5.2kg/ytterbium, 3.7kg of yttrium, and 1.9kg of strontium were extracted from the ore liquid in a mine pit.
The total weight of rare metals exceeds [-] kilograms. In addition, some conventional metals such as iron, copper, and titanium have also been smelted, but the quantity is not large, and they are incidental products. .

There is only one reason for the formation of this super-large rare earth concentrate, and that is super-intense geological activity.

The weathering crust elution-type rare earth deposit in Sichuan was actually formed by the violent geological activities that occurred when the Indian Ocean plate and the Eurasian plate collided when the Himalayas were formed.

During plate collisions, the upwelling of asthenospheric material induces the collision zone, and partial melting of the lithosphere-rich mantle leads to the formation of carbon dioxide-rich silicate magma.

The magma will rise and emplace along the fault zone formed by the collision, forming a magma chamber in the shallower part.

In the end, these magmas deposited and cooled on the surface, and were eroded by wind, rain, oxygen, etc., thus separating a large amount of fluids rich in rare metals and common elements.

And these fluids undergo water/rock fusion reaction with the ascent and emplacement of the separated carbonatite and syenite magma, finally forming rare earth deposits.

In this type of ore-forming environment, the enriched carbon dioxide in the magma is the key.

Without it, the magma that rises due to geological activity will not be eroded, and eventually it will not form rare earth ore, but will form flint, obsidian, igneous rock and other things.

In Chuandu, Huaguo, the reason why there are so many rare earth mines is because of the collision between the Eurasian continental plate and the Indian Ocean plate.

As for the rare earth deposits in the Baiyun Obo area of ​​Inner Mongolia, it is another form of 'undersea volcanic mineralization'.

All the rare metals collected from Huaguo have been smelted. Han Won has treated the waste water formed during the smelting of minerals, and then preserved the extracted rare metals.

Including this weathered crust elution-type rare earth mine, these smelted rare metals increased the progress of the resource collection task to 87.34%.

The progress of the task of resource collection has reached more than 80.00%, and the won has been satisfied. Next, we have to hurry up and deal with the artificial smelting and synthesis of three unnatural elements.

Although there are still more than three months before the second year, which is enough for him to complete the second basic condition, Han Yuan still wants to continue to increase the progress of some resource collection tasks.

Including making some preparations for the third year's Starlink mission branch chain mission [-] 'Guardian of Civilization'.

The requirement for civilization protection is to produce a nuclear fission weapon or nuclear fusion weapon within three years (the explosive power is required to be no less than [-] tons of TNT equivalent.)
For this mission, although the system gives two options, one is nuclear fission weapons and the other is nuclear fusion weapons.

But in fact, for him, there is only one option, and that is nuclear fission weapons.

Because compared with nuclear fusion weapons, the manufacture of nuclear fission weapons is simpler, and the detonation of nuclear fusion weapons requires nuclear fission bombs.

Nuclear fusion weapons are also called 'hydrogen bombs' or 'deuterium bombs, tritium bombs', which are a type of nuclear weapons.

The energy released by the nuclear fusion reaction of hydrogen isotopes (deuterium and tritium) is used to carry out killing and destruction.

热核反应基本公式是3|1H+2|1H—→4|2He+1|0n+1.76×10^7eV，换成汉语就是氘+氚→氦+中子+能量。

It can be seen from this formula that the raw materials for fusion are deuterium and tritium.

But if you want to make two kinds of lightweight atoms (deuterium + tritium) undergo nuclear fusion reactions, you can only do so at extremely high temperatures, which need to be greater than 4000°C (0000 million degrees) and have a large enough collision probability. Happens a lot.

Therefore, it is extremely difficult to detonate a nuclear fusion weapon, which requires placing a small nuclear bomb inside the hydrogen bomb.

Detonate the nuclear bomb first, let it reach the temperature of the reaction condition in an instant, and then cause the fusion of deuterium and tritium, and then explode.

So to make a nuclear fusion weapon, you need to make a nuclear fission weapon first.

This is a precondition.

And the precondition itself can complete the task, why bother to make another fusion weapon.

Therefore, nuclear fission weapons have become the answer to the task of protecting the branch chain of civilization.

When it comes to nuclear fission weapons, the most common one is the atomic bomb.

For human beings, there are only three fissile substances, uranium-235, plutonium-239 and uranium-233, that can be obtained in large quantities and used as atomic bomb charges.

These three substances are the raw materials for the manufacture of the first generation of nuclear weapons, and uranium 235 is the main charge of the atomic bomb.

Uranium 235 is derived from natural uranium. Among about 140 natural uranium atoms, there is 1 uranium 235 atom. It is extracted and enriched, which is the material for making atomic bombs.

This is also the easiest way to make an atomic bomb.

For Won, more than three months is enough time for him to artificially synthesize gamma nickel, carbon nanotubes and Li8.

For the rest of the time, he will go out to look for uranium ore, collect and collect a large amount of uranium ore and come back.

In natural uranium, the content of uranium 235 is less than one percent, and it is not an easy task to separate it.

Even if he has mastered the technology of separating uranium 235, a large amount of uranium ore is needed to obtain enriched uranium 235 that can be collected.

Although the system mall can be exchanged for finished products, there are prerequisites. After several years of exploration, the Korean won has been roughly mastered.

If you want to exchange technology points for raw materials from the system store, you need to have at least one gram of corresponding raw materials.

In other words, if he wants to exchange for one unit of uranium-235, he needs to smelt one gram of uranium-235 first.

Moreover, the exchanged materials are the same as the materials he smelted in terms of concentration and quality.

If the concentration of uranium 235 he smelts is only [-]%, the exchanged value will also be this value.

This is a restriction that cannot be bypassed. The Korean Won has tried many times but there is no way.

In addition to uranium, natural radioactive elements include polonium, radon, francium, radium, actinium, thorium, and protactinium.

He hasn't collected these radioactive elements yet.

Won plans to use 45 days to complete the smelting and synthesis of the three unnatural elements, and the remaining 50 will be used to search for natural radioactive elements outside and try to smelt them out.

After all, the higher the degree of completion of the branch chain task, the richer the reward.

Although it is not easy for him to smelt these radioactive elements, it is not too difficult.

Moreover, these natural radioactive elements are also very useful for his later technological development.

Radioactive substances may sound scary, but they are not uncommon in reality.

Whether it is as low as daily food or as high as the cutting-edge technology of human beings, it is inseparable from this thing.

For example, carbon 14, an isotope of artificially synthesized carbon, is weakly radioactive and is often used to mark the trajectory of compounds, many of which are cosmetics or food materials.

It's just that the radiation that comes with this thing is too weak for the human body, even if you inhale some, there is no problem.

And natural radioactive elements, people are exposed to a lot in life, just like radon.

This naturally radioactive element is contained in minerals such as granite, brick sand, cement and gypsum, which are used in large quantities in construction.

Especially some natural stones containing radioactive elements, such as marble, granite, etc., are most likely to release radon.

Radon is much more harmful than carbon-14.

It is a radioactive gas. When people inhale it, the decayed alpha particles of radon can cause radiation damage in the human respiratory system and cause lung cancer.

So it is always thought that natural things are good, and some inferior marble furniture or floor tiles can kill you without knowing how.

Just like the WHO once counted a set of data, radon is the second most important cause of lung cancer in many countries (more than 40), including China.

Moreover, radon can increase the probability of lung cancer in smokers.

Simply put, if you smoke in a room with marble decoration, your chances of getting lung cancer will be greater.

However, radon, a radioactive gas, is of great use to Korean won.

In the construction of the subsequent controllable nuclear fusion reactor, it is a kind of marking thing, which can be used as a gas tracer, similar to the probe made before, and can be used to understand the gas operation status and Condition.

So he had to smelt radon again.

As for other natural radioactive elements, they also have different uses. If there is time to smelt these substances, Won will not delay.

It is right to prepare these things, even if they are useless now, maybe they will be used someday?
