Using a group of sika deer to transport ore, naturally once again brought a strong shock to everyone, but what made everyone even more excited was that these ores may be gold mines with extremely high gold content, plus Zhu Yan and Chen Lan also mined more than 60 wild ginseng, so there is no problem with the funds for the construction of the base.

"Xiao Yan, do these ores really contain gold sand?" The senior brother touched a piece of ore of fifty catties and asked in disbelief.

"Senior brother, the density of gold is about seven times that of ordinary stones, and even if the gold content of gold ore is only a few ten-thousandths, it is much heavier than ordinary stones. You see, although the volume of this ore is only the size of a flower pot, it weighs fifty or sixty catties, which is far from the weight that ordinary stones can reach. Look at the golden yellow sand grains in this ore, that is gold sand. ”

Zhu Yan picked up another piece of ore, pointed to the golden particles dotted on the ore facet, and said to Senior Brother.

"Yes, it's not an ordinary stone, and the particles look like gold sand, but could it be chalcopyrite? I've heard that chalcopyrite looks very similar to gold. Teacher Chen hesitated for a moment and raised his own questions.

At this time, the reporters who were taking pictures of the group of sika deer also came over, and they were also very interested in the composition of the ore.

"If we separate all the particles in the ore, we can determine whether it is gold or not by measuring the density. However, how to separate them from the ore is a difficult problem. ”

Lao Yang, who is in his forties, is also a senior reporter among these people, he has been a science columnist for almost 20 years, and he has never eaten pork and seen pigs run, so he naturally saw the key to the problem at a glance.

"I heard that when screening gold sand from gold placer ore, it is generally crushed first, and then the difference in density between gold and stone chips is used for panning, which is called gold panning. Why don't we crush one of the ores and put it in this creek to see? ”

Higher education is different, and reporter Xiao Li, one of them, reacted quickly, and immediately thought of an operational method. As soon as this method was proposed, it was immediately endorsed by many people present.

"Just, will this pollute the creek?"

Reporter Zhou was a little hesitant, if the beautiful environment here was destroyed, then what was the point of them living in seclusion?

"Perhaps, I have a way to separate the gold sand from it without the washing method." At this time, Zhu Yan, who had been muttering for a long time, suddenly said.

"Really? Brother, how do you dig out these beautiful little beans? ”

Zhu Yan's words aroused everyone's curiosity at once, and Jingjing's eyes widened even more, staring at him directly.

"Jingjing, do you like these little beans? Brother will get them out for you to use as toys, okay? ”

"Xiao Yan, do you want to pick out these particles one by one? They're so small, almost as big as a grain of sand, how do you pick them all? ”

Mr. Chen was obviously also puzzled, his brows were furrowed, racking his brains, and suddenly he seemed to grasp something, and said excitedly: "Yes, although this method cannot completely separate all the particles, but there is no problem in separating a part of it for determining density!" If these particles were really gold, it would not be too late for us to find other ways to separate them! ”

Zhu Yan nodded, although he didn't think of the method that Teacher Chen said, but what Teacher Chen said was indeed a good way to determine the density of gold sand, and it was easy to be recognized by everyone.

After deciding on the method, everyone began to get busy, some were looking for sledgehammers, some were preparing containers, and some even brought a set of density measuring tools, such as graduated cylinders, balances, etc., and it was difficult for them to prepare so carefully.

The elder brother took the sledgehammer as he pleased, and he found a slightly smaller piece of ore, put it on top of another larger piece of ore, and then turned the hammer and smashed it.

Hearing a roar, sparks splashed on the stone, and a huge piece of ore suddenly fell apart, and an obvious crack appeared along with the large ore below. Although the density of placer gold ore is large, because the associated quartz is brittle, it cannot withstand knocking, so it is easy to weather and crush in nature.

The elder brother continued to wheel the sledgehammer and smashed the cracked small ores again, and after a while, the ore completely turned into a pile of mineral powder, and the air was also filled with countless dust.

The next work is relatively easy, first use the dry panning method to discard the lighter ore powder, leaving only a layer of heavier ore chips, and then everyone will work together to pick out the golden yellow sand particles one by one and put them into the container that has been prepared.

Although it is not easy to pick gold sand in a pile of ore chips, but fortunately, there are many people with great strength, and after more than half an hour, the gold sand is finally all picked, and there are more than a dozen grams of golden sand grains in the container.

After the grains were completely washed and dried, they began the second task: determining the density of the grains.

Take a part of the sand grains, first weigh the mass, then measure their volume with a graduated cylinder containing water, and finally divide the mass by the volume to determine the density of the sand grains.

Ten minutes later, the results came out, with a density of 19.30 grams per cubic centimeter, indicating that the golden sand grains were gold, and the ore transported by the sika deer was gold placer. At this time, the audience cheered, but they didn't expect that there was a rich gold mine hidden in Changbai Mountain, and the funds of the base were no longer a problem.

Of course, they would never publicize the discovery of gold, otherwise the gold would never have their share. According to the laws of Huaxia, all natural resources belong to the state, and individuals have no right to possess them, even if you find this thing first, it is useless. It is said that someone dug up a piece of gold in his own field, did not hand it over to the state, but secretly sold it, and was later reported and arrested and imprisoned.

This statement may be a bit excessive, but Reporter Zhou knows a real thing, because she had personally covered the news at that time. The news is that a farmer in a certain place dug up a gloomy wood in his own field, and when he told others, he knew that the gloomy wood was worth tens of millions, and when he was ecstatic, the local government came to the door and asked him to immediately hand over the gloomy wood to the government, otherwise he would bear the consequences. In the end, he was reluctant, but helpless to send the gloomy wood out.

Fortunately, this valley is isolated from the world, and without the help of the crow and Zhu Yan, it is impossible for the people in the valley to go out, which makes it almost impossible for the news to leak, and there is no fear that the government will come to collect the gold sand.

The biggest problem at the moment is how to quickly separate the gold sand in these ores, like the selection method just now, I don't know how many months it will take to separate the ore pile. Besides, they are here to cultivate, not professional miners, how can they spend all their time on mining?

For everyone's troubles, Zhu Yan had already made up his mind, and he, Master, Senior Brother, Chen Lan, and Teacher Chen and his wife took turns to smash those ores one by one with a sledgehammer.

Smashing ore is not only a hard work, but also a kind of cultivation, and it can only be cultivated if you have a certain amount of spiritual energy cultivation. In this process, it is important to turn qi into strength, that is, to transform the aura in the body into strength in the arm, so as to not only exercise the body, but also speed up the absorption of the vitality of heaven and earth by constantly consuming the aura.

The warrior monks of Shaolin Temple have to chop wood, carry water, and carry stones every day, which is actually a way of cultivation, and physical training and vitality absorption are originally complementary things.

For the crushed ore, Zhu Yan thought of a way to directly let the gold sand inside jump out, this method is currently only available to him alone, which is essentially an aura drive, similar to his previous "Flying Stone Divine Skill".

Because the gold sand contains far more vitality than quartz sand, it is easy to lock, Zhu Yan can lock dozens of gold sand at the same time, and then by adjusting the aura filaments attached to the gold sand, you can make these gold sand hang in the air and separate from the powder.

This is also an extremely aura-consuming thing, but it is also because of this, it is extremely beneficial to Zhu Yan's cultivation. He was going to separate all these crushed ores by himself, and then teach them the method when Chen Lan, Master, and Senior Brother had their spiritual qi cultivation up.

In this way, in the next few days, the sika deer transported all the ore hidden in the dense forest, and then Zhu Yan, Master and Senior Brother separated the gold sand inside. The others continued to be busy with the construction of the base, and a few more vegetable fields and medicinal fields were reclaimed, because the gold placer was mined, the sixty or so wild ginseng plants were not sold, and they were transplanted into a medicine field with a particularly strong vitality, and after Zhu Yan treated them with aura, they are now growing very well.

It is also worth mentioning that after a few days of observation, Master Zhang Zhongyi finally agreed to Reporter Zhou's repeated requests and accepted the eight of them as apprentices, so Zhu Yan's fellow brothers and sisters were even more.

Five days later, all the placer gold mines were cleaned up, and Zhu Yan and the others separated more than 1,000 grams of high-purity gold sand in one fell swoop. As long as they are sold for money, the urgent need of the base will be solved, and it seems that they will have to go to the mountain.
