Hand rubbing nuclear fusion live in the wilderness

Chapter 380 Greatly Inspired Experts from Various Countries

The choice of artificially smelting and synthesizing three unnatural elements has been decided, and Han Yuan is not in a hurry to deal with it.

Now there are other things to deal with first. The weathered crust elution-type rare earth collected from Chuandu is still waiting for him to extract the rare metals in it.

In fact, there are also differences in rare earth mines, generally divided into two types.

Heavy rare earths and light rare earths.

In the north of China, there are mostly light rare earth resources.

For example, bastnaesite is mainly distributed in the Baiyun Obo mining area in Inner Mongolia. Its rare earth reserves account for more than 80.00% of the total rare earth reserves in the country, ranking first in the world, and it is the main production base of light rare earths in Huaguo.

In the south, there are mostly medium and heavy rare earth resources, such as ionic rare earth ores, which are mainly distributed in Chuandu, Xijiang and other places.

Compared with light rare earths, heavy rare earths are more expensive and are generally used in high-tech fields such as aerospace, military, national defense and new material synthesis.

The most important thing is that there is almost no substitute for heavy rare earths.

This means that materials that need to be doped with heavy and rare metals, and no other elements can be found to replace these things, so it is the lifeblood.

The ion-adsorption type rare earth mine in Chuandu was actually chosen by South Korean won.

The ion-adsorbed rare earth mines, at least the ones that have been proven so far, are basically all within the territory of China, and there are no other countries.

It belongs to the heavy ion type rare earth, which contains gadolinium, terbium, dysprosium, holmium, erbium, thulium, ytterbium, lutetium and so on.

Has a higher atomic number and greater mass.

There is a purpose for South Korea to separate out these weathering crust elution-type rare earths for final smelting.

Although compared to other countries, Huaguo has the most complete rare earth smelting method and rare metal recovery method in the world today.

But because only one country, Huaguo, is groping for the reason for this road, the smelting methods have been limited so far.

At least Huaguo's smelting methods, even if they have developed to the third generation of smelting technology, still have serious flaws.

At present, Huaguo's smelting method for ion-adsorbed rare earths is mainly hydro-smelting.

Rare earths are first mined, then acid-dissolved, extracted after dissolution, and then precipitated and burned to obtain rare metals.

This is a widely used method for smelting ionic adsorbed rare earths.

However, after this method is acid-dissolved, the waste acid water contains a large amount of rare metal ions and cannot be extracted.

Of course, such and such defects are only defects in the eyes of Won.

In the eyes of other countries, this is not the case, such as the United States, which actually has the second largest rare earth mine stock in the world, second only to China.

In the United States, although there is a lack of ion-adsorbed rare earth mines, there are also heavy rare earth mines.

With China's emphasis on heavy rare earths and restrictions on exports, rare earth mining companies in the United States are also gradually developing their own domestic heavy rare earths.

It's just that although they have some heavy rare earth mines, they don't have the technology to smelt heavy rare earths.

There is no smelting technology, so the heavy rare earth produced can only be concentrated, and then sent to the factory in Huaguo for smelting and separation.

Of course, the South Korean won will not destroy such a good situation.

That's why he smelted the ion-adsorbed rare earths unique to Hua, which are not available in the United States, and smelted them to improve the domestic rare earth smelting technology.

After preparing all the relevant materials for smelting, the Korean won came to the lower reaches of the small river.

There is a newly erected steel factory here, built by chimpanzees and bonobos.

There are quite a few similar buildings beside this small river. During the days when he left, the chimpanzees didn't sit around and wait to die every day. They always had to do something.

Before that, Han Yuan obtained some simple drawings and materials, and handed them over to the bonobo who had been injected with genetic modification drugs, and then led and supervised other chimpanzees to complete the construction of the house.

Although the houses built by chimpanzees are very simple, there is no problem in sheltering from wind and rain, and it doesn't matter if they are used as smelters, which have general environmental requirements.

Ion-adsorbed rare earths, like other rare earth ore smelting, require a large amount of water for processing. There are several large deep pits near the plant, which are similar to the pits dug by South Korean won when they selected rare earth ores at the Mount Tai base.

It's just that these deep pits are bigger, and concrete is applied inside to drain water.

The most important thing is that some of these deep pits are like lead-acid batteries, with tanks, separators, positive plates, negative plates, terminals and other things.

If a large amount of electrolyte is filled into this pool, this huge pit with a diameter of ten meters will become an extremely huge battery.

This is the Korean won for smelting ion-absorbing rare earths.

After processing the materials in hand, South Korean Won began to smelt ion-adsorbed rare earths.

These collected rare earths are crushed in a crusher, then ground into a fine powder by a mill and sent to a deep pit.

While dealing with rare earths, Han Yuan explained the relevant methods and precautions.

"Ion-adsorbed rare earths have special properties, and the rare metals in them are attached to conventional soil in an ion state."

"In this way, special methods are required to smelt it."

"And the smelting method I prepared is called 'electrolysis-ion exchange method', which is specially used to smelt ion-adsorbed rare earths."

"The initial steps of this method are similar to smelting other rare earths. They all need to be crushed into powder, then stirred and fused with water to form mineral water, and then the precipitate is filtered and filled with flotation liquid for flotation."

"Different from the ordinary rare metal ore flotation process, the results of ion adsorption rare earth flotation are opposite."

"It needs to retain the mineral water from the flotation, and pour off the froth and sedimented residue."

While Han Yuan was explaining, he was processing the collected weathered shell leaching-type rare earth, crushing it and turning it into powder.

In the live broadcast room, the major mining companies that have already received the news have arranged for their R&D personnel to sit in the live broadcast room and listen carefully.

Although the method explained by the anchor is only applicable to ion-adsorbed rare earths, it is not unhelpful for other types of rare earth smelting.

Especially the light rare earth one.

Although light rare earths were discovered earlier than heavy rare metals, human smelting technology and application technology for light rare earths are immature, so its use and importance are not as good as heavy rare metals.

But that's just that humans haven't found a suitable way to use it, and it doesn't mean that light rare earths are not important.

Light and rare metals such as lanthanum, cerium, praseodymium, neodymium, promethium, samarium, europium, etc., play a huge role in metallurgy, ceramics, chemical industry, electronics, medical treatment, superconductivity and other fields.

The space shuttle of the United States, as the crystallization of mankind's top technology, uses a large amount of light and rare metals on it.

Such as the heat-proof tiles of the shell, the superconducting metal wires inside, etc., are all made of materials doped with light rare metals.

It's just that compared to heavy rare metals, light rare metals have a tortuous path to development.

In addition, the stock of light rare earths is large, which is also one of the reasons why the status of light rare earths is not as good as that of heavy rare earths.

Compared with 90.00% of the world's heavy rare earths are in China, light rare earths are all over the world, and most countries have them.

It is a pity that although there is a large stock of light rare earths, the smelting technology of various countries is not mature.

Many light rare earths are special ion-type ore veins. Although they are not ion-adsorption type, the difficulty of smelting is much greater than that of ordinary rare metal ores.

The 'electrolysis-ion exchange method' that South Korean Won is currently explaining seems to be applicable to the smelting of light rare earths.

This has naturally attracted the attention of various countries and mining companies, hoping to get some technology or inspiration from it to smelt their own rare earth ores.

In particular, Huaguo, as well as domestic rare earth companies, have arranged a large number of researchers to watch this live broadcast.

Huaguo's heavy rare earths account for 90.00% of the world's eighth, ranking first in the world.

And even light rare earths have nearly one-third of the world's total.

Therefore, how to smelt rare metal ores and rare earth ores at low cost has always been the focus of Huaguo.

At present, the smelting technology for various rare earth minerals has been developed to the third generation, and no other country can match it.

Like ion-adsorbed rare earths, Huaguo has several sets of its own complete smelting technologies.

Such as solvent extraction method, ion exchange method, wet smelting, etc., can smelt rare metal ions adsorbed in the soil in an ion state.

However, without exception, the extraction efficiency of these methods for ion-adsorbed rare earths is very average.

The smelted rare earth waste still contains a large amount of rare metals that have not been extracted, which not only wastes resources, but also pollutes the environment.

Although there are a large number of ion-adsorbed rare earth ores found in the territory, Huaguo has been suppressing the mining of ion-adsorbed rare earth ores because it has not found a suitable and perfect smelting method.

And today, a perfect solution is finally available.

"Because of the particularity of the ion-absorbing rare earth, the rare metal ions contained in it normally do not participate in the reaction with other external substances."

"Means like traditional pyrometallurgy and hydrometallurgy cannot work on it."

"That's why it's so hard to use this kind of rare earth mine."

"As for the 'electrolysis-ion exchange method' I used this time, there are two most critical steps in smelting ion-adsorbed rare earths through it. One is the configuration of the flotation solution, and the other is the configuration of the electrolyte."

"These two things are related to whether rare metal ions can be replaced from rare earths."

"Because many rare metals have their unique properties or are very active, conventional electrolysis methods can't play a role in their deposition, so unique flotation solutions and electrolytes are needed for treatment."

"."

In the live broadcast room, while handling the rare earths and various solvents in his hands, Han Yuan explained the points that need to be paid attention to in smelting ion-adsorbed rare earths.

Outside the live broadcast room, everyone in the mineral industry was watching the live broadcast attentively, even if they were not related to rare earths, they were watching and listening carefully.

Ion-adsorbing minerals do not only appear on rare metals, but also in other types of mines.

This electrolysis-ion exchange smelting method has certain inspirations for experts and people in the mineral industry.

Perhaps this method can also be used for smelting other minerals.

And the ones who were most inspired were of course experts in Huaguo's rare mineral mining industry.

Ion-adsorbed rare earths, this is a unique mineral in Huaguo, with a large storage capacity and high grade, and many of them are heavy rare earths, which contain a large amount of heavy rare metals.

Therefore, how to smelt this kind of ore soil has always been the object of research by rare metal mineral experts.

Electrolysis, ion exchange, etc. have all been studied, but they were all abandoned because of some problems.

It is mainly due to the characteristics of rare metals that it is difficult to smelt them through these methods.

For a long time, relevant experts have agreed that this is a dead end.

No one thought that this impracticable road was now being walked through, and it was a living rehearsal in front of them.

This kind of thing can't help but make people sigh, but at the same time it also attracted their attention.

"It turned out to be like this. No wonder we couldn't get through this way."

In Huaguo, an expert in the rare earth industry sighed while watching the live broadcast.

This is an academician, Xue Tan Shuang Huan, who is close to his age, but is still busy in the laboratory, guiding students.

This is the root of a country and the foundation of a country's prosperity, which is admirable.

By watching Won's live broadcast, he clearly understood why he had problems and failed when he and others were studying ion-adsorption rare earth smelting.

He was amazed by the way Han Yuan smelted rare metals, but then the academician seemed to think of something, picked up his mobile phone and made a call, exchanged a few words with the person opposite him emotionally, and then concentrated on the live broadcast.

From the smelting method of Korean won, he speculated on other ways to smelt various minerals, but it needs to be confirmed from live broadcast and actual experiments.

If it proves to work, it could be a technology that could revolutionize the mining industry today.

And being able to master this kind of technology, perhaps in the future Huaguo will no longer lack various metal minerals and can achieve self-sufficiency.

In the live broadcast room, South Korean won's smelting of weathered crust elution-type rare earths is still going on.

Several large pits dug by the river have been filled with various ore liquids, some of which have just been melted, and some of which have undergone preliminary flotation.

There is also an electrolytic pool where the treated ionic ore liquid is being smelted.

Around the big pit, the Leluo triangular aircraft rested on the ground safely, and the power line pulled out from it provided a steady stream of current for this smelting ground.

And in the ionic type mineral liquid pit, there are various clapboards, cathode/anode, line segments and other items to be framed in the pit liquid.

The current derived from the aircraft continuously flows into these items, smelting the ore liquid in the pit, extracting the rare metal ions in the ore liquid, allowing them to deposit and attach to the cathode.

The mine pit is very large and there is a lot of ore liquid in it. It is a long process to extract the rare metal ions in it.
