The pick-up process was unusually low-key. Pen % fun % Pavilion www.biquge.info

After the two Il-76s landed at the airport, they were towed and dragged into the exclusive hangar of Behemoth Industries.

Then the tailgate of the engine room opened, and two giant laborers drove large forklifts to transfer those coffin-like lead cabinets to container heavy trucks one by one.

A few hours later, the lead cabinets were sold at the Longxitan factory.

In the underground base, a rare metal purification plant with a very high degree of industrialization has been established, but the scale is not large, with a daily production capacity of about 100 tons at most.

This is because when the plant in the Sotu rainforest is completed, the metal purification will take place there.

At that time, it will be directly airlifted to the ground, which is a piece of high-purity silvery-white metal dysprosium.

In the highly clean sealed underground factory, Ye Qing was wearing protective clothing, and stood aside with great excitement in his heart, watching the huge laborers cut through the lead cabinets one by one and took out piles of gray-brown metal ingots from them.

These are raw materials with a metal purity of 80% and a dysprosium content of about 8%.

In front of Ye Qing, there are industrial equipment in the shape of silver-white metal cylinders. At the end of these devices, there are numerous reactors, and a huge metal furnace.

They are purification equipment, and Juli has already begun to move the raw materials of these metal ingots, stacking them in a vacuum arc furnace for the first stage of melting.

The refining method of rare earth metal ore is both simple and complex.

To put it simply, it is so simple that some lawbreakers secretly organize people to go to the mine to steal mine. It is only necessary to drill dense deep holes in the mine and inject specific chemicals into these deep holes to react with the rare earth ore and oxidize and dissolve the metal elements inside. These solutions are then extracted from the deep wells and injected into the pool for further processing.

How to deal with it?

It is broadly divided into three categories, acid method, alkali method and chlorination decomposition. The extracted solution contains a large number of rare metal elements, and the principle of chemical change is used to reduce them into crystals, and finally these crystals are ground into powder, and rare earth metal raw materials can be sold.

Why is the theft of rare earths repeatedly banned in China? It is because by using these large-scale chemical raw materials that can be purchased at will, rare earth metal raw materials can be extracted from raw ores.

These raw materials are piled up in sheds like flour, and each bag smuggled out can be sold for tens of thousands of yuan.

But this method seriously harms the natural environment. Usually a hole is punched in a mountain and liquid chemicals are injected into it, and the vegetation of the entire mountain withers.

The extracted solution uses a lot of water in the chemical reduction process. Criminals directly discharge this used polluted water into lakes and rivers, and the only result is a large-scale death of aquatic organisms.

This is a simple purification method.

The complex purification method is the one that is being used in the Longxitan factory.

Juli Laborers put the raw materials from the previous mini-factory, through grinding and magnetic separation, and finally die-casting into ingots, into a vacuum furnace, heated to 3,500 degrees, and vaporized all the metal substances inside. These metal gases are then directly introduced into a centrifuge, and the different metal molecules in the metal gas are further purified and separated by gas centrifugation.

Gas centrifuge, just three simple words.

It represents an insurmountable height in the industrial field.

Because mastering this method, it is possible to master the purification of enriched uranium-235 from uranium ore.

Originally, Ye Qing could choose a low-cost chemical reaction purification technology, and with a strong ionization sewage treatment system, Ye Qing could avoid any water pollution. However, gas centrifugation can be used not only to separate the various single metal molecules in these rare metals. It can also lay the foundation for the purification of calcium-uranium mica minerals mined in the mining area.

Ye Qing didn't plan to build an atomic bomb, and to build an atomic bomb, tens of thousands of centrifuges needed to work in parallel.

But energy towers need materials to produce more energy, and enriched uranium-235 is the best material available.

Using the energy tower to power the centrifuge, as soon as the gas centrifuge was turned on, Ye Qing, who was standing in the plant, suddenly felt that a high-power vibrating machine was connected to the world, and one was also stuffed in his brain, and even the blood was vibrating rapidly.

There are hundreds of centrifuges in front of you, and the speed of each centrifuge per minute reaches 100,000 revolutions.

What is this concept?

There are a lot of supercars on the market that claim to be able to blow up the streets, and the maximum speed of the engine per minute can reach 10,000 even if it is the sky, and at 10,000 rpm, it can be maintained for more than five minutes is considered a miracle.

These centrifuges are 100,000 revolutions, and this is its normal working speed, which has to be maintained for more than a day.

However, at a speed of 100,000 revolutions per minute, the hundreds of centrifuges in front of Ye Qing looked at it with the naked eye, and there was no jitter, not even the resonance of the shell.

This shows that the balance of the spindle of these centrifuges has reached an incredible technical level. And the noise around Ye Qing was not a mechanical roar similar to that of an engine, but the feeling that every molecule in the air was vibrating.

In front of these industrial equipment, even 10,000 supercars are nothing?

Can a supercar engine use a magnetic bearing that does not make any physical contact? The spindle of a supercar engine can achieve a straightness close to perfect, and the internal crystal structure is neatly arranged, even if it is cut into hundreds of pieces, the weight error of each section is not more than a hair, that is, the weight of 0.5 thousandths of a gram?

can't do it, the centrifuges in front of Ye Qing are more technical than those centrifuges used to separate uranium-235 in those big countries. This is also the reason why Ye Qing chose to hide in the underground base, just get a set of chemical purification equipment that will produce a large amount of chemically polluted water in the factory outside.

After staying in the sealing factory for less than two minutes, Ye Qing ran out sweating profusely. Although the industrial power is shocking, it is impossible to violate the manpower.

However, the final purification results of the centrifuge can be observed by another equipment.

The name of the equipment is gas sedimentation chamber, which varies according to the weight of the metal molecules. The centrifuge separates the heaviest metals in turn. For example, scandium, lanthanum, cerium, and dysprosium, these metals have different densities, which also create different molecular weights.

The gas centrifuges used by major countries can separate uranium-235 and 238 from uranium.

You must know that uranium-235 is only 1.6% lighter than 238, but under the high-speed rotation of the centrifuge, the slightly heavier 238 will be thrown to the periphery, not to mention the rare earth metal elements with a greater molecular weight difference.

At nine o'clock in the evening, in the underground base of the factory, the metal elements separated for the third time slowly gathered in the settling chamber.

These glittering silver gases, after cooling, are sprayed directly on a transparent glass substrate, slowly accumulating higher and higher like snow.

It didn't take long for a piece of metal dysprosium weighing one ton to appear quietly in front of Ye Qing like this.
