The phenomenon of Chinese people collecting protection money from their own people caused quite a huge sensation in China because Song Yu came out. Pen & Fun & Pavilion www.biquge.info

There are many people discussing this matter in China, and on the Internet, those gangsters who specialize in collecting their own protection fees are even more scolded by netizens.

Song Yu himself didn't expect that he would clean up a gangster and set off a hoarse accusation against overseas Chinese gangsters in the distant country of China.

And in Congo, Song Yu's influence has further expanded, and it has almost become synonymous with "hero".

"It's so handsome! Dr. Song's actions when he saved people were so cool! ”

"I've completely become Dr. Song's brainless fan."

"If it weren't for the fact that this was a live video, and it hadn't been post-produced, I couldn't believe that in real life, this kind of scene could really happen, like an action movie in a movie!"

Many TV viewers were amazed by Song Yu, and some people asked ignorantly: "Which movie is this star?" ”

For a while, what made Song Yu feel quite speechless was that many big directors asked for his contact information from nowhere, and they were ready to let him star in some kung fu movies!

For these, Song Yu simply refused. With his current fame and status, as well as money, there is no need to make a movie at all, and he has never planned to do so.

The path Song Yu wants to take is a medical and commercial path, and he doesn't want to waste time in other aspects for the time being.

In addition, because of the gangsters, not only Song Yu has attracted attention, but also Song Yu's diamond mine has also attracted the attention of some people.

Those civilians all focused on how Song Yu heroically saved people, but many elites focused on Song Yu's mine.

They inquired through many parties, and Song Yu bought the process of making this mine.

"How could Song Yu have thought of buying mines in Congo? It would be understandable if it was bigger, but such a small mine is not worth Song Yu's personal effort to buy, right? "Some elites are starting to analyze.

"I think Song Yu must have thought that this mine was worth buying, so he made a sale. In other words, the value of this diamond mine may be far greater than you and I can imagine! ”

"It's impossible, just a small mine, such a large area, how much value can be created? I look at this mine, 100 million may not be able to make Song Yu earn! ”

"Song Yu's behavior is indeed a bit incredible, but according to the information I have gotten, the first diamond found in the mine is gem grade, and I feel that the purity of the diamond mine here must not be low!"

"Song Yu wants to make a lot of money, we must reach a cooperation with Song Yu before others! Nowadays, diamonds of high purity are not so easy to find. The boss of a diamond jewelry company.

And Likasi's largest mining developer also put his mind on Song Yu's mine: "Sit and see the situation first, and if possible, you must buy this mine as soon as possible." ”

……

In the morning, because the last batch of machinery arrived, Song Yu got up extra early and went with Jia Lianzhou to see how the new machinery was running.

"Captain Jia, your injuries are not healed yet, you need to recuperate in the hospital for a few more days." Song Yu ran over when he saw that Jia Lianzhou's injury was not yet healed, and hurriedly persuaded.

"This little injury is nothing, and today is the official start of operation of our mine, how can I not be there?" Jia Lianzhou's attitude is very resolute.

Jia Yulan heard that the mining team had officially started construction today, and she also rushed to visit.

Song Yu asked with some concern: "You girl, you didn't get a big shock yesterday, did you?" ”

Jia Yulan shook her head: "I was scared at first, but later, I wasn't afraid at all." Thank you, Brother Song Yu, if it wasn't for you yesterday, I wouldn't know what to do. ”

"You don't have to thank me, but the next time you encounter something like this, don't be strong, otherwise it's easy to be in danger, you know?"

"Understood, I must listen to Brother Song Yu!"

Song Yu nodded in satisfaction, his gaze refocusing on the machinery he had just delivered.

Jia Lianzhou said solemnly: "Pour some of the twenty tons of ore mined the day before yesterday into it." ”

"Okay, right away!" The assistant had the ore poured into the machine.

The machine is actually a large crusher, according to the characteristics of the hardness of the diamond far exceeds the hardness of the stone, in the crushing process, the diamond can be preserved intact, but the stone is chopped into small stones with a diameter of fifteen centimeters.

At this time, someone will inspect the conveyor belt to see if it can find large diamonds.

If there are no large diamonds, then the next step is to crush. The machine will crush these small 15-centimeter stones into stone grains with a diameter of between 2.5 cm and 5 cm. During this process, if the ore contains diamonds larger than 5 cm in diameter, it will be cut into smaller diamonds smaller than 5 cm.

The losses are enormous.

The value of large diamonds, and the value of small diamonds, increase exponentially, not just by simply accumulating the body. To put it simply, on the basis of the same quality, the sum of ten one-carat diamonds is completely different from the value of one ten-carat diamond!

Therefore, after the first crushing powder, it is necessary to find a few more people to check whether the stone contains large diameter diamonds. If there is, it must be taken out immediately to avoid huge losses.

After the workers carefully inspected, everyone was a little disappointed that there were no such large-volume diamonds in the smashed stones.

Subsequently, the stones were cut into stone grains.

At this point, it's actually hard to see which stone has diamonds on it and which doesn't.

This brings us to the next step.

Song Yu and Jia Yulan both looked very fresh, only Jia Lianzhou and other old skilled workers showed a trace of nervousness and expectation on their faces.

Because diamonds have a specific gravity of 3.52, they are heavier than many minerals in stone grains. According to this characteristic, the crushed ore and the slurry with a fixed gravity are placed together in a turntable and rotated and stirred, and the light minerals with a small specific gravity will float away, while the heavy minerals such as diamonds will remain at the bottom of the turntable to form a concentrate.

The concentrate is then placed in a denser heavy liquid, and after rotation, diamonds and other more minerals are gathered at the bottom and walls of the container, while light minerals float in the center of the surface of the container. After this process, a much larger weight of concentrate remains, which is about one thousandth of the weight of the ore before separation.

At this point, move on to the last step.

The staff will coat the conveyor belt with grease, and according to the characteristics of the diamond when it is stained with oil, the diamond can be easily separated from other minerals, and the staff will take out the diamond stuck to the conveyor belt.

After some process, the first diamond is finally removed from the conveyor belt.

This diamond is very small, less than 50 cents (100 cents for a carat), and it is not worth much, but because of its good clarity, it can be regarded as better than nothing.

Then some diamonds were removed from the conveyor belt.

Most of these diamonds have a good clarity. And such a ratio, placed outside, is definitely high and scary! Generally, there can be 20% diamonds, and the clarity reaches gem level or above, which is considered qualified.

Therefore, this diamond mine of Song Yu is undoubtedly a treasure trove!

However, it is not unreasonable for Angelo, the original owner of the mine, to give up on continuing mining and abandon the mine.

In addition to clarity, the most important thing should be the yield. Obviously, the production of diamonds is not good, and after twenty tons of ore, the final diamond is only 2 carats, and all of them are very fine diamonds, which are of little use.

Jia Lianzhou was extremely disappointed, he thought that his daughter could kick out a two-carat diamond with a casual kick, and the output of this mine should not be bad, but he didn't expect the result to be such a big surprise.

You know, generally speaking, the quality of diamonds that can be extracted from 20 tons of ore is 5 carats! And Song Yu's mine, extracted, can't even reach half of the output.

"Dad, Brother Song Yu, don't be discouraged, add my diamond to 4 carats, that's not much different from the average of 5 carats!" Jia Yulan comforted.

"That's right, it's too early to draw conclusions, it's better to mine two hundred tons of ore first, and then see the results. If the results are still unsatisfactory, then we can at least reduce the cost of mining by adopting the underground mining model.

Song Yu knew about the underground mining model. In general, when the cost of open-pit mining is greater than the value of the resulting diamonds, open-pit mining should be stopped immediately and mined underground. However, underground mining can lead to some waste, and it is not as clean as open-pit mining.

The 200-ton stone is mined in just one hour, followed by a step-by-step process for the crushing of the stone and sorting of the diamonds.

Everyone was nervous.

Jia Lianzhou's eyes stared at the conveyor belt motionlessly, his heart beating faster.

Jia Yulan's eyes widened, for fear of missing any detail.

Song Yu squinted slightly, and was also watching nervously.

Finally, a pure white diamond of about three carats appeared in everyone's sight.

Jia Lianzhou was excited, looking at this white diamond with the naked eye, there is absolutely no flaw, it should be a very high-quality white diamond! Even if it's not a D grade, it should be F or higher!

As long as it can reach F grade and above, it can be recognized as a high-quality diamond, and the value is not small.

Then, there were bits and pieces on the conveyor belt, and some diamonds under 1 carat were produced, which naturally dwarfed the high-quality white diamond of three carats.

Everyone breathed a sigh of relief, in fact, with this 3-carat high-quality white diamond, even if there were no grains today, they would almost be able to recover the cost paid for this day.

Immediately afterwards, on the conveyor belt, a lot of diamonds came out of the conveyor belt.

And just when everyone thought that there would be no more amazing diamonds, suddenly a blue diamond of a little more than two carats appeared in front of everyone's eyes!

Blue diamonds are not very dark in color, but their value should not be underestimated.

More importantly, its appearance made Jia Lianzhou and others feel great hope, that is, this diamond mine can produce precious colored diamonds!
