Hand rubbing nuclear fusion live in the wilderness

Chapter 438 Purification of Uranium

Under the joint action of the 'condensation nuclei degradation agent', more than 30 tons of CL-20 high-explosive bombs and nature, at noon, the overwhelming dark clouds almost dissipated, and the sky began to gradually clear up.

Seeing this scene, the audience in the live broadcast room were amazed.

You must know that it was still raining not long ago, but now the sun has come out.

This act of manipulating the weather against the sky is really amazing.

The only pity is that the technology is not mature enough, and there is no way to move the huge cloud layer on a large scale and send it to the designated location.

If it can be done, it is really perfect.

At that time, it can be said that there will be no place on the entire earth that is desolate, and the fragrance of fish and rice flowers will be everywhere.

Although it is a pity that this rain elimination technology is not as perfect as imagined, the role of the 'condensation nuclei degradant' still caused countries to immediately launch actions to try to replicate it.

After all, the role of this solvent is still quite large.

It can still play a considerable role in the face of flood disasters caused by heavy rain.

In addition, plasma condensation nuclei have also opened up a new research path for meteorological experts from various countries.

This may very well be the path to the ultimate secret of weather.

If it can be mastered, humans may be able to conquer nature.

The bright sunlight returned to the earth and shone on the aircraft.

A heavy rain washed away the dust and other pollutants on the aircraft, and gallium lanthanide silicon solar thin film power generation panels ushered in a new round of work.

Twelve X-1 industrial robots continued to work after replenishing their electrical energy.

Rumbling pumps drain the water from the puddles and replace it with cloudy solution pumped from the mines.

After a full two days and two nights of erosion, the solution has been filled with various ions such as uranium ions, thorium ions, and silicon ions, as well as various impurities such as soil and gravel.

The extracted solution is placed in a puddle, and as time goes by, impurities such as soil and gravel will settle down, and the surface will gradually become clear.

Through guidance, the clear floating water flows to another pool for further processing, and the impurities deposited at the bottom are not wasted, and are collected and stacked on the other side.

These soil, gravel and other impurities also contain a lot of uranium, which can be smelted out through some technical means.

Of course, the method of separating uranium from impurities is definitely different from the method used to separate clear uranium liquid. The procedure of the former is more complicated, while the latter is simpler.

Seeing that Won started to process the liquid uranium, the live broadcast room became lively, and the audience discussed and communicated with passion.

[After watching the mining of uranium and then the refining of uranium, it's wonderful. 】

【Hey, after I finish learning, I can. Hey hey hey】

【Dig the uranium ore first, then powder it, then heat the centrifuge, and then you can get uranium-235. 】

[What do you think will happen if you jump into this pool and take a bath? 】

[Then the whole village can go to your house for dinner. 】

【Good guy, I want to sit at your wife's table. 】

【I sit at the child's table. 】

【I'll sit at the young woman's table. 】

【Isn’t there a uranium mine in Xijiang? I belong to Xijiang, and it’s nearby, so I have a bold idea. 】

[Upstairs, for your bold idea, our country has a complete set of criminal laws, and the criminal police have agility.The special police have precise marksmanship, the coffin has a fancy way to make it, there are more than 100 ways to burn the corpse, and the cemetery has a good burial method. 】

[Although I have watched hundreds of uranium extractions on station b, I still want to hear how the anchor extracts uranium. 】

[It’s useless to tell you how to make a nuclear bomb. The trading of uranium is prohibited. If you buy it on the front foot, the country on the back foot will give you a pair of rose gold bracelets. 】

【Brother, the prison sewing machine needs a talent like you. 】

Looking at these gaudy bullet screens, Han Yuan couldn't help laughing.

"The extraction of uranium ore is actually quite simple."

With that said, Han Yuan stretched out his finger to the clear uranium water after sedimentation and filtration: "For example, this kind of uranium liquid extracted from the intrusion liquid contains a large amount of uranium ions, which can be precipitated by adding the corresponding extraction agent. .”

"The leaching solution I used this time is an acidic leaching solution, which contains not only uranium ions, but also certain types of other metal ions and impurities."

"The extraction process of this acid leachate includes a purification-precipitation process."

"And when I let the solution stand still before, it was to let the insoluble impurities such as soil and gravel settle down first."

"As for the solution that has been precipitated, how to separate the uranium ions in it is also very simple."

After a pause, Han Yuan continued: "This step is actually not much different from the purification of other metals, such as gold."

"It's just that the extraction agents used in the two are different. Just like the gold in the gold-plating solution can be adsorbed on the zinc wire, the uranium ions in these infiltration solutions can also be adsorbed on the resin."

"Of course, this resin is specially made, and it is an ion exchange resin."

"By allowing the leach solution to fully contact the ion exchange resin, the resin can absorb the uranium in the leach solution."

"After the adsorption of the resin reaches the maximum capacity saturation, the uranium in the resin is then desorbed with an analytic agent to form an analytic solution containing uranium with high purity. The analytic solution is further purified and precipitated to obtain uranium."

"After the uranium is extracted, it can be used to extract the uranium 235 in it."

Won briefly introduced the whole process of refining uranium.

For him, the extraction of uranium is actually quite simple, even simpler than the extraction of aluminum.

Aluminum also needs to go through processes such as cryolite + electrolysis, but uranium is not used, and it can be extracted through extraction and precipitation.

Although some of the viewers in the live broadcast room didn't really believe or be optimistic about the resin that Han Yuan said could be used to extract uranium, but soon, the facts were proved to them.

A large number of pre-prepared ion-adsorbing resin **-1 industrial robots were put into the solution after precipitation.

Immediately, fine and small bubbles appeared in the originally clear solution.

This is exactly the performance of ionic resin in adsorbing uranium ions in the solution.

After checking the status of the solution and resin, Han Yuan directed the X-1 industrial robot to move out a huge polyester plastic bucket from the aircraft.

Inside the barrel is a light black solution with a normal viscosity, which looks like pure water mixed with black ink.

The moment the lid was lifted, a slightly pungent smell wafted in the air.

The audience in the live broadcast room asked curiously, and Han Yuan explained: "This is used to promote the adsorption of uranium ions in the solution by the ionic resin."

Hearing this, the audience in the live broadcast room immediately asked about the name and ingredients of this kind of thing, as well as how to configure it.

Seeing these concerned bullet screens, Han Yuan smiled and said, "It's actually an ordinary alkaline solution, which is used to adjust the pH value of the solution, and many things can be substituted."

Let the X-1 industrial robot dilute the adjustment solution in the bucket according to the proportion and pour it into the solution. In an instant, the solution in the entire puddle reacts violently.

The fine and small bubbles that originally came out will directly turn into longan-sized foam.

Just like washing dishes with detergent, the huge puddles are full of large and small white foam, which refracts colorful rays of light under the sunlight and then disappears quickly.

[Like soapy water. 】

【Lori happy water ()】

[Ma Dan, after explaining, you still haven't said the name and ingredients of this thing, the anchor. 】

[You asked so detailed upstairs, what do you want to do? 】

[The extraction of uranium is actually very simple. This extraction method uses sodium hydroxide (NaOH) to replace the things in the hands of the anchor to accelerate the adsorption speed of uranium ions. 】

【? ? ? ? 】

[Friend, you are breaking the law, do you know that?You broke the law! 】

[Pull out and shoot for half an hour (ω )]

There were jokes and fights in the live broadcast room.

Han Yuan looked at these bullet screens and smiled, but didn't say much.

It is indeed possible to use sodium hydroxide (NaOH) as an acid-base regulator for the extraction of uranium metal, but the efficiency is not as high as that used by him.

Han Yuan is not worried that the audience in the live broadcast room will learn how to make a nuclear bomb from him.

Because ordinary people can't get uranium at all, not even rough uranium.

And a small amount of uranium and uranium rough is useless.

After all, the content of uranium 235, which can produce chain reactions and be used to manufacture nuclear weapons, is only about 0.7% in natural uranium, which is extremely low.

Under the technical conditions of perfect purification of uranium 235, at least 14.6kg of U235 is required for a nuclear explosion.

Of course, this is the critical mass condition without a neutron-reflecting layer and without special compression treatments.

If a thick reflective layer and an exaggerated amount of explosive are used at the same time, only 235 kilograms of uranium-[-] can be critical and detonated.

But even with the addition of a thick reflective layer and an exaggerated amount of explosives, 235 kilograms of uranium-[-] is not so easy to extract.

Not all uranium mines have such a high grade as the one under his feet.

铀矿品位一般为0.05%—0.10%。以哈萨克斯坦为例，现已开采的18个铀矿中，最低品位为0.03%，最高品位达0.204%(北哈拉桑1号矿)。

Based on the highest grade of 0.204%, [-] tons of uranium ore are needed to extract [-] kg of natural uranium.

In one hundred kilograms of natural uranium, even if all the uranium 235 in it is extracted, it is only 0.7 kilograms, which is less than one kilogram.

If the critical point of 5.2 kg is required, then more than seven hundred kg of natural uranium is required.

Note that this is natural uranium, not uranium metal that has been refined.

All uranium metal sold on the market has gone through extraction and other steps.

The uranium 235, 233 and other elements in it are basically extracted, and the remaining uranium 235 and 233 in it are not many elements that can be used to make nuclear weapons.

And 35 kilograms of natural uranium requires about [-] tons of natural uranium ore.

If it is not known that a uranium mine has lost 35 tons of ore, it can only be said that the country will sooner or later pill.

So Han Yuan is not worried that someone will learn the manufacturing technology of nuclear bombs from his live broadcast room.

Compared with the extraction and enrichment of uranium 235 and other technologies, how to obtain a large amount of uranium is the most difficult.

In his previous life, the current Card Dazuo once paid one billion US dollars to buy about one kilogram of 95% uranium-235 from nuclear-armed countries, but no one was willing to sell it.

Of course, this also has something to do with Ka Dazuo offending all five benefactors.

After all, he bought uranium 235 to make nuclear bombs, and everyone was afraid that he would go crazy and throw the nuclear bomb on his head.

After handing over the accelerator to the X-1 industrial robot, Won no longer cared about it.

The extraction of solution from underground uranium mines, the precipitation of solution, and the release of accelerators can all be done by these industrial robots.

Impurities such as deposited soil and resin adsorbed with uranium ions will be piled together.

These things will be purified by him after the extraction of the solution is completed.

The extraction of the solution, the precipitation, the release of the accelerator, and the adsorption of uranium ions are a long process.

By the time these steps were all completed, half a month had passed.

As expected by Won, not all the solution injected into the mining area can be extracted.

Won did some calculations, and the extracted solution was close to [-] tons, which was a little more than one-third of his previous estimate.

Within half a month, all the uranium in the solution had been extracted.

In other words, it becomes a resin that absorbs uranium ions and deposits uranium impurities inside.

The next job is to extract the uranium from the ionic resin and impurities.

This step is not difficult either.

Extracting uranium from impurities is a bit more complicated, but it is fairly simple to extract uranium from ionotropic resins

After the ion-type resin absorbs uranium ions and reaches the maximum capacity saturation, the uranium in the resin is desorbed with a desorbent to form a desorption solution containing uranium with high purity.

After the analysis solution is obtained, it is concentrated, and after concentration, the analysis solution is mixed with a precipitant, so that the uranium ions in it can be precipitated.

The so-called precipitant is actually very common in daily life.

Common items in life such as ammonia gas or ammonia water, caustic soda (sodium hydroxide), magnesium oxide, and hydrogen peroxide can do it.

This is actually the use of chemical extraction methods to carry out.

Utilizing the different solubility of uranium in a specific organic phase and aqueous phase solution and the mutual immiscibility of the two phases, it is possible to separate uranium from impurities and realize the purification and precipitation of uranium solution.

The steps and items needed are outrageously simple.

Even the audience in the live broadcast room were complaining.

[Madan, I never thought that the purification of uranium would be so simple. 】

[Hydrogen peroxide can precipitate uranium from uranium solution. I really didn't expect it. I still have two bottles of this thing at home. 】

[Sodium hydroxide is not edible alkali?Many stomach medicines contain this. 】

[Go out to buy hydrogen peroxide for disinfection in the future, boss, bring a bottle of hydrogen peroxide, the boss frowned, looking at you vigilantly, show your ID card, comrade! 】

[The refining of uranium is really not complicated. There is nothing interesting about it. Uranium is actually just a metal. The refining and enrichment of uranium 235 is the key to making nuclear weapons. 】

[The extraction and enrichment of uranium 235 is not complicated. I have a complete set of preparation methods in hand, which were saved before the net clean operation. 】

[Good guy, punishment! 】

[Give me a copy from upstairs, I'll pay ten yuan! 】

[I will pay 100 yuan! 】

[Stop arguing, I will offer 1 yuan! 】
