Chapter 748: Manufacturing Dysprosium metal.

The pick-up process was very discreet. After the two IL - 76 landed at the airport, they were pulled into the Huge Industrial Monster's exclusive hangar by a tractor. Then the engine room tailgate was opened and two Monster Laborers drove a giant forklift, transferring long, narrow crate lead containers one by one to the heavy trucks container ship, and a few hours later these cabinets in lead arrived at the Longxitan factory.

In the underground base, a rare metal purification plant with a very high degree of industrialization was established, it was not large, but its daily purification capacity was about 100 tons at most.

Indeed, metal purification work will be carried out there in Nigeria when the Sotu Rainforest plant is completed. Immediately after that, the two IL - 76 aircraft will carry only pieces of high-purity silver-white metallic Dysprosium.

Inside the very clean and sealed underground factory, Ye Qing, wearing protective clothing, stood aside with incomparable excitement, watching the giant worker open lead cabinets and take out stacks of ingots of grey-brown metal. These are raw materials with a metallic purity of 80% and a metallic Dysprosium content of approximately 8%. In front of him was industrial equipment in the shape of silver-white metal cylinders. At the end of these facilities, there were many reactors and a huge metal furnace. These are purification equipment, and Juli has already started transporting these metal ingots, stacking them in a vacuum arc furnace for early smelting work.

The method of mining rare earth ore is both simple and complicated.

To put it simply and there's nothing quite as simple as that, so, if some criminals wanted to secretly organize people to go into the mines to steal minerals. They just have to drill deep and dense holes in the mine, then inject specific chemical substances into these deep holes, which can react with the rare earth ore and oxidize and dissolve the internal metallic elements. The solution obtained from this intervention will then be extracted from the deep wells and injected into a pool for further treatment.

How to do this?

Roughly divided into three categories, acid categories, chlorination category, and chlorination decomposition category, the extracted solution contained a large number of rare metal elements. And using the principle of a chemical transformation, they are reduced to crystals. Finally, these crystals are ground into powder to obtain rare earth metal raw materials that can be sold.

……

Why do European countries and the United States continue to steal rare piles of the earth, despite repeated bans?

It is through the use of these large-scale chemical raw materials that can be purchased at will and can be used to extract rare earth metal raw materials from raw ores.

These raw materials are piled up like flour in the shed, and each bag of contraband goods can be sold for tens of thousands of dollars.

However, this method seriously harms the natural environment. Usually, if a hill is hit with a liquid chemical injected into it, the vegetation all over the hill withers, these extracted solutions require a lot of water resources in the chemical reduction process. Criminals directly dump used polluted water into lakes and rivers, and the only result is that aquatic organisms die in large areas.

……

It was a simple purification method, and the complex purification method is the one used in the Longxitan factory.

The industrious Juli put the raw materials in the previous mini-factory, for grinding and magnetic separation, and finally pressure-cast them into ingots, and placed them in a vacuum furnace, heating them to 3,500 degrees and gasifying them at all metallic substances inside. Then, these metallic gases were directly introduced into the centrifuge, and the various metallic molecules in the metallic gas are further purified and separated by gas centrifugation.

……

Originally, Ye Qing could choose chemical reaction purification technology at a lower cost, but with the powerful ionization sewage treatment system, Ye Qing could avoid any water pollution problems. However, gas centrifugation could only be unused to separate various simple metal molecules in these rare metals. It could also lay the foundation for the purification of mica calcium uranium minerals mined in the mining area.

Ye Qing did not intend to build an atomic bomb and to build an atomic bomb will require tens of thousands of centrifuges to work in parallel, but the energy towers required input materials to generate more energy, and enriched uranium 235 is the best material currently available.

The Energy Tower is used to power the Centrifuge. As soon as the gas centrifuge was turned on, Ye Qing, who was standing in the workshop, felt that a high-powered vibration machine connected between heaven and earth was vibrating rapidly. There was a total of hundreds of centrifuges in front of him, each centrifuge spins at 100,000 rounds per minute.

……

But what is this concept?

There are plenty of super sports cars on the market that claims to be able to blast the streets. The maximum engine speed per minute can reach 10,000 rpm, and it's a miracle. Under the condition of 10,000 rpm, it can be maintained for five minutes, and it can last more than five minutes when running under 10,000 rpm.

……

Those centrifuges in front of him were spinning at 100,000 rpm, and that's their normal working speed, which will last more than a day. However, under the condition of 100,000 rpm, there were hundreds of centrifuges in front of Ye Qing, and with the naked eye, he could notice that there was no vibration, not even shell resonance. This shows that the balance of the main shafts of these centrifuges has reached an incredible technical level. And the noise around Ye Qing was not the mechanical roar of an engine, but every molecule in the air surrounding him was vibrating.

Faced with this industrial equipment, what is even 10,000 rpm?

Can a supercar engine use a magnetic suspension bearing without any physical contact? The main motor shaft of the supercar can achieve almost perfect straightness, and the internal crystal structure is carefully arranged. Even if it is cut into hundreds of sections, the weight error of each section is no more than one hairline or 0.5 thousandths of one gram in weight.

What Ye Qing couldn't do in the factory outside, the centrifuges in front of his eyes were even more technical than the centrifuges used by those big countries to separate uranium-235. This is also the reason why Ye Qing chose to hide in the underground base, and the plant outside would only need to procure a set of chemical purification equipment which would produce a lot of chemically polluted water.

After staying in the sealed factory for less than two minutes, Ye Qing started sweating profusely. Although industrial power is shocking, human power cannot be violated. This is why he went to observe the final result of the purification of the centrifuge via another device.

The name of the device is the gas settling chamber, which varies according to the weight of the metal molecules. The centrifuge separates the heaviest metals in turn. Like scandium, lanthanum, cerium, and Dysprosium, these metals have different densities which also results in different metal molecular weights.

……

The gas centrifuges used by major countries make it possible to separate uranium 235 and 238 from uranium. It should be noted 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 metallic elements of rare earth with a higher molecular weight.

……

At nine o'clock in the evening, in the underground base of the factory, the metallic elements separated for the third time slowly gathered in the settlement chamber, and after cooling, these brilliant silver gases were sprayed directly onto a layer of a transparent glass substrate and slowly accumulated higher and higher like snow.

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