Next, Fang Jinyan used the purchased several pieces of metallurgical equipment to start processing the more than one ton of ore that he had collected in the barren mountains and mountains.
Although such equipment is too simple compared to the metallurgical factory before the end of the world, it is enough for the current Fang Jinyan. 15 tons of ore, no industrial refining method is required at all, it is enough to use laboratory refining method.
First, he used a stone crusher to crush all the ore into fine sand, so as to increase the contact area and increase the speed of the chemical reaction.
Then, he used fluorite calcium fluoride to react with concentrated sulfuric acid to produce a large amount of hydrofluoric acid.
Fluorite and concentrated sulfuric acid are also what he bought in the black market, and it is said that they were obtained from the Ningzhou Industrial Park not far away, because there are many private individuals who are also researching evolutionary organisms, so these chemicals are very marketable, so it is not surprising that they are sold in the black market.
Because hydrofluoric acid is volatile and highly toxic, Fang Jinyan took protective measures from the beginning.
Then, he slowly threw the previously obtained mineral sand into the hydrofluoric acid solution, because the reaction was very violent, and if too much was put in at one time, it would definitely explode.
Fang Jinyan knew that the main component of this ore is silica, in addition to some other substances such as iron oxide, and hydrofluoric acid has the ability to dissolve various oxides.
In peacetime, it has been widely used in the refining of aluminum and uranium.
Hydrofluoric acid is a super diacid, it corrodes dissolved substances, not limited to oxides, in fact, except for a few substances such as lead, gold, platinum, etc., most other common inorganic substances can basically be dissolved Fang Jinyan threw all the ore into hydrofluoric acid, and in the end almost all of it was dissolved, and only a very small amount of sediment appeared.
After standing overnight, Fang Jinyan carefully separated the solution from the precipitate early the next morning.
The sediment looked very strange, and even after the solution had been completely separated, the granular form still did not sink to the bottom of the container.
It's as if the Earth has lost its gravitational pull, and they're all levitated Fang Jinyan was not surprised, because he knew that this was just an optical illusion In fact, these particulate substances are not suspended, but are supported by other substances, which are invisible to the human eye.
This kind of substance is what Fang Jinyan really wants to get, and those suspended particles are actually just hydrofluoric acid that failed to dissolve impurities, and need to be further purified by other methods Although the vision is completely invisible, under Fang Jinyan's perception, it can be clearly "seen", it is a crimson substance.
Fang Jinyan knew that it was dark matter, a substance that could only be detected by the sentient sense Because dark matter itself does not emit electromagnetic radiation and does not interact with electromagnetic waves, humans cannot observe it with their eyes, and even various detection instruments cannot directly observe them, and only through the effects of gravity can we know the existence of a large amount of dark matter in the universe.
In fact, dark matter and dark energy represent more than 90% of the matter content in the universe, and the matter we can see only accounts for about 5% of the total matter in the universe.
It's just that for a long time, it was thought that there was no dark matter on Earth.
It's just that the experience of his previous life made Fang Jinyan know that in fact, there is dark matter on the earth It's just that it's hard to spot because the number is too small and it's not observable with optical and electromagnetic devices However, some people believe that in fact, there was no dark matter on the earth before, and the sudden appearance of dark matter may be related to the dark energy storm.
As to who is right and who is wrong in these two views, there is still no result until Fang Jinyan is reborn.
However, for the current Fang Jinyan, it is not very important.
Importantly, in this life he should be the first person to refine dark matter Fang Jinyan reached into the container, grabbed a handful, and pinched this completely transparent substance in his hand, feeling like grabbing a handful of sand.
Because this dark matter is also solid and has shapes, the human sense of touch can be felt, but the sense of touch must be touched to sense, and if the dark matter is mixed with a large number of other substances, it is naturally impossible to find it.
In fact, even if the awakened perception of the evolutionary is difficult to find dark matter, because the dark matter on the earth is basically mixed in the ore, because it is too rare, so in the perceptual vision, the color is very, very thin, and it cannot be found without conscious identification.
In addition, the range of evolutionary perception is too small, far inferior to vision, and generally can only radiate a distance of three to five meters, so until now, I have not heard of other evolutionaries discovering dark matter.
And the reason why Fang Jinyan was able to find it was actually because he remembered the location in his previous life, where dark matter ore appeared, and even remembered the color form of that ore, and then consciously searched for it, so he found it.
And it's also a rare open-pit mineable dark matter ore with a high content.
Other ores are either buried deep underground or have very low content, which can be many times more difficult to refine.
Unfortunately, it is a bit small, and only 15 tons of raw ore were found in total.
Therefore, even if the content is as high as 1 or more, the final dark matter obtained is only 16 kilograms Next, Fang Jinyan heated these dark matter particles to 1,600 degrees Celsius, let them completely melt, and turned them into something like molten iron, and then used a special mold to shape and cool them.
The result is a 4-meter-long gun.
And its diameter, but only 1 centimeter, this proportion can be said to be very, very fine, if it is a general material, even the best quality steel, it is estimated that the battle will be bent and broken after a while.
However, Fang Jinyan knew that this gun would not break at all, because the hardness of this dark matter was 10 times greater than that of diamond, and it was impossible to break it.
If not, why would he go to the trouble of using it to make weapons?
In fact, in the previous life, this kind of dark matter was called "dark iron", and many evolutionary weapons were made from it, and only such weapons could bring the strength of advanced evolutionaries, especially those with strength talents, to the extreme.
With the growth of the evolutionary physique, ordinary weapons simply can't keep up with the rhythm.
Just like the last time Fang Jinyan killed the mutant beast, because the power was too great, he directly broke the spear.
While some alloy steel weapons should not be phased out anytime soon, dark iron weapons are clearly better weapons.
Because an increase in hardness also means an increase in sharpness.
According to the custom of the previous life, spears over 4 meters above are called dragon spears, because they resemble the guns in the hands of the legendary dragon knights.
A gun of this length cannot be used by ordinary people, but advanced evolutionaries can control it very well, because advanced evolutionaries have super reaction speed, movement and coordination abilities, and can fully exert its power.
This is especially true for a superbrain talent like Fang Jinyan It's just that in this period, the dark iron weapon is too special to be easily exposed, so he used the electroplating method to coat it with a layer of nickel metal, so that it is no longer transparent, and it looks like just an ordinary metal spear.
The reason why nickel metal was chosen is because this metal can shield the senses, so that other evolutionaries cannot sense the existence of dark matter inside.
This is also the experience of rebirth, and there are many people in previous lives who have used this method to deal with dark matter weapons, and the effect is very good.
In this way, Fang Jinyan spent a huge amount of financial resources and energy to finally make the world's first dark matter weapon However, he didn't feel a loss at all, because he knew very well the power of this weapon, and it was definitely worth it.
At this point, Fang Jinyan said that all the plans were basically completed, and he decided to leave here as soon as possible and proceed with his next operation.

But at this time, Xu Xiaoyao suddenly ran over and told him: A person who claimed to be "Zhao Neng" came to him, saying that he had something important to discuss with him.
Fang Jinyan thought for a moment, and quickly remembered that it seemed to be the person he met at the gate of the base that day, the captain of the Changfeng Hunting Team.
"It's strange, I'm just a one-sided relationship with him, what can he do with me, could it be that he wants to pull me into the gang again" Fang Jinyan muttered to himself, and then walked towards the door. t1706231537:
