In fact, it is not difficult to separate the iron element alone.

It's just that it will definitely not be an easy task not to destroy the special molecular structure of this iron.

Once the metal minerals are acted on chemically, it is likely to destroy the structure of iron.

Due to the limited amount of minerals, there is not much room for error in the exploration of this substance.

After organizing the experts of the project team together, Xu You asked everyone about some of the previous research on this mineral.

"Professor Xu, after our research on this metal mineral, we found that there is indeed a special form of iron in it. This iron is different from all the iron we have found, and is combined in a similar molecular form .”

Normal iron has the structure of a single atom, and there is no molecular structure like this.

This form is somewhat similar to the iron clusters studied by Xu You and Xu Zhou before, but there are some differences in comparison.

"Has there been any breakthroughs in isolating this particular form of iron?"

"We have tried various chemical methods to separate this iron, and we have indeed successfully separated the iron element, but the molecular structure of iron has been destroyed during the reaction."

Xu You nodded slightly, which was consistent with what he had guessed before.

When doing experiments on iron atomic clusters, Xu You found that the structure of atomic clusters is easily destroyed by some chemical reactions.

The same situation really appeared in this new type of substance.

"It seems that it is difficult to successfully separate these new types of iron through chemical methods." Xu You thought.

If only the iron element is separated, regardless of whether it will destroy the molecular structure of iron, then such separation is completely meaningless.

But if you don't use any chemical method, it is very difficult to separate a substance from a mineral.

Thinking of this, Xu You couldn't help but frowned and began to think.

Lin Shi, like Xu You, was also thinking about relevant methods after hearing the narrations of these experts.

After thinking for a while, Lin Shi took the lead and said:

"In other words, if you want to successfully separate this special iron from the mineral, you can't use any chemical methods."

"Yes, judging from the current experimental phenomena, this is indeed the case. Of course, some chemical reactions are not ruled out, and will not destroy the special structure of this new type of iron. However, because the fault tolerance rate is very limited, we have not yet Finding a suitable chemical reaction can successfully separate iron without destroying its molecular structure."

This time, although hundreds of kilograms of lunar samples were brought back from the moon, the number of samples containing this special mineral composition is still very limited.

The experts did not dare to use too many samples for experiments. After all, there were still some ores that were to be preserved for collection.

Xu You also knew this reason, before the next mission to the moon was carried out, too many experiments could not be carried out with the existing ore.

At this time, Lin Shi continued:

"Then can we use a purely physical method to complete the separation of this new type of iron?"

Hearing Lin Shi's words, everyone felt a little surprised, thinking that Lin Shi's idea was too bizarre.

In the purification of any kind of mineral, almost no purely physical method is used, unless the purity of the mineral itself is already very high.

Because everyone didn't know much about Lin Shi, they thought that this girl who had just joined the project team was just expressing her own opinions casually.

However, everyone knows that Lin Shi was brought here by Xu You.

Because of their awe of Xu You, they still dare not make any sense of Lin Shi's thoughts casually.

Xu You, who knew Lin Shi well, knew that since Lin Shi put forward such an idea, there must be his own reasons.

"Lin Shi, is there any direction you can try?"

"I think that iron can be separated by using the characteristic that iron can be attracted by magnets. Just using magnetism will not damage the structure of iron."

Hearing Lin Shi's idea, some experts couldn't help laughing slightly.

"Mr. Lin, you need to know that besides iron, there is also nickel in minerals, and nickel, like iron, can be attracted by magnets. What's more, these different kinds of substances are combined together, relying only on magnetic properties characteristics, how to complete the separation between different substances?"

Lin Shi heard the words and said calmly: "I know that in addition to iron and nickel in minerals, their specific susceptibility coefficients are not the same. As long as the magnetic field is set to a suitable parameter, the separation of different substances can be completed in theory. In the separation Previously, we could process minerals into tiny powders, so that we could use magnetic fields to purify new types of iron."

Lin Shi's idea suddenly awakened Xu You, which is indeed a feasible direction in theory.

"That's right, Lin Shi's direction is indeed feasible. With the size of the new iron molecular structure, our existing technology can process the mineral into a corresponding size. We have completed it in the experiment before." similar experiments."

At this moment, Xu You had to admit that it was indeed the right thing to bring Lin Shi here this time.

Even if Xu You was given some more time, Xu You should have thought of this direction.

But Lin Shi brought up this direction in time, which bought precious time for the project team.

It can be seen that Lin Shi really worked very hard in the laboratory before to accumulate knowledge so solidly.

Seeing that her idea was adopted by Xu You, Lin Shi didn't say anything, but she felt a little proud in her heart.

Lin Shi used his spare time to review a large number of documents, especially all the achievements made by Xu You.

It was from Xu You's research on iron atomic clusters that Lin Shi learned about some related properties, which gave her the inspiration she has today.

With Xu You's affirmation, no one dared to question Lin Shi's opinion anymore.

After formulating a complete plan, Xu You and others started a new round of experiments.

Because physical changes will not destroy the molecular structure of matter, in the process of physical, everyone finally does not have to walk on eggshells like before.

Xu You put the minerals into a ball mill and milled them at a speed of 300 revolutions per minute for an hour to fully grind the minerals into powder.

Using this time, Xu You studied the previous experimental data again, and performed various simulations in his brain from time to time.

"Before 1400 degrees Celsius, the structure of the new iron will not change. After roasting at this temperature, it can be magnetically separated."
