Vajim exclaimed in amazement:

"it! There is heavy metal pollution in the water!"

Otherwise, why would the metal detector sound?

"Poof~~~~" Ling Feng almost vomited blood, there is heavy metal pollution in the Shente River, is it because you have a hole in your brain?

He rolled his eyes speechlessly, shook his head, and everyone quickly reacted, perhaps, there is a treasure in this river?

Fuck it, the cock is blowing up, this is really a god!

"Di Di ~" "Di Di Di ~" "Di Di ~"

Wajim excitedly continued to probe-

From the foot of the back mountain, he probed forward along the road, and there was a low-intensity metal reaction in the section of the river that was nearly 100 meters.

Verafia and Yuri speculated:

"That's not right! It's a long time, could it be that there are some pipes underground? The metal reaction is very weak!"

"Possibly, the metal reaction is too weak. ”

"Is it an abandoned water pipe?"

They muttered curious guesses, but vaguely expected to have some surprises, what if there was a treasure?

The more Wajim probed, the more excited he became, and with a smile on his face full of ecstatic excitement, he interrupted his guess: "No, no, no, this is not a treasure. ”

"It's not a waste water pipe!"

"What if... If I'm not mistaken...", he pointed to the oscilloscope/display on the treasure finder and introduced it to the crowd:

"First of all, these metals are not magnetically permeable. ”

"Exclude three kinds of iron, cobalt and nickel!"

"Secondly, the detection ripples are uniform and dense. ”

"It means that the metal is dense and scattered, and it is not a single piece or a long strip, but it is likely to be sandy or reticulated. ”

"Metals that meet the above conditions—"

"Most likely a Sands deposit. ”

It is worthy of the retirement of the Vympel special forces, and the reckless man quickly came to the right conclusion, and it is also well-founded.

Ling Feng also confidently supported:

"That's right, it should be the Jinsha vein!"

"Just take a look at it. ”

He fell to the ground, prostrate himself by the river, picked up a handful of coarse sand from the icy water, and tossed it in the water.

Faintly, you can see the small golden sand.

Back and forth, left and right, up and down, back and forth, back and forth, and after observing, more golden sand suddenly appeared.

"Hiss~~~~" everyone's pupils shrank sharply, and they couldn't help but gasp for a breath of Siberian -15 °C cool air.

stared at Jinsha in a daze and shouted:

"Oh my God, gold? really gold?"

"Sukabule, there is actually a gold vein, is our farm fated with gold? I can't believe it..."

"Boss, do we want to mine?"

There was a sudden silence and everyone looked at each other, if gold is mined, it will affect the environment, and the sediment flow is very serious.

Heavy metal contamination can poison fish!

Ling Feng pursed his lips and asked, "I don't know, do you have a way to mine gold ore without pollution?"

Vera and Feiya, two beautiful women, shook their heads.

The Yuri couple also shrugged their shoulders in denial.

How could they possibly have a solution?

Wajim suggested: "No way, boss, why don't you ask the proprietress Eva, she might have a way?"

If you are in a hurry to go to the doctor, you can only do this!

Ling Feng reluctantly called Eva-

Soon, the video call was connected, and Eva whispered a gentle greeting in the office: "Morning, dear, wait, what are you doing here?

"Don't you tell me what you've found?"

She had a vague hunch that her boyfriend had twice discovered the gold of the Tsar's treasure, and it was normal to find it the third time.

Do you want to find yourself to arrange a sale?

Eva looked at her boyfriend with surprised curiosity.

Ling Feng shook his head secretly:

"No, it's not a treasure, listen to me Eva, do you know any equipment that can absorb gold matter?"

"Or, non-polluting mining of mineral sand. ”

"Mineral sands are extracted from the bottom of the river without pollution. ”

"Don't let the sediment wash away with the river. ”

He asked with anticipation on his face, and Eva also looked at Ling Feng slightly confused, not understanding what the situation was.

Mining, gold, adsorption, what the hell?

After contacting before and after, she suddenly realized!

Gold ore, definitely a golden sand, right?

After careful consideration, she replied: "First of all, gold is not a permeable metal, and it certainly cannot be magnetically attracted. ”

"In addition, pollution-free sand mining, you can!"

"The vacuum pump truck can pump sand without pollution. ”

Vacuum pump truck, similar to vacuum suction truck.

It has a large steel canister and a thick plastic pipe that is connected from the tank to a target, which is sucked by pressure.

The extractor is on the other side of the tank!

Extractor-tank-pipeline-suction target

The working principle is that the pressure in the steel tank is small, and the suction target is directly extracted from the mixed liquid into the steel tank.

The extractor is not in contact with the extraction target.

As a result, high hardness mineral sands can be sucked up.

The blades of the pump of the pumping machine will not touch the ore, of course, it is not afraid of being damaged, the ore just enters the steel tank from the pipe, and it is precipitated at the bottom of the steel tank, and it is filled and released from the open warehouse.

It is also possible to release only water, but not mineral sand.

The large vacuum pump has a very strong suction power, which can easily suck stones and concrete into the storage tank.

Not to mention mineral sand, no pressure!

Moreover, as long as the suction is strong and the speed is fast, the mineral sand will not be washed away by water, and the sucking will be clean and efficient.

Much cleaner than mechanical sand pumping.

As for washing, you can completely change places, and in a modern mining company, you can get it by paying tens of thousands of yuan.

They have advanced automatic sand panning equipment.

Perfectly solves the problem of water pollution!

Ling Feng is like an initiation, fuck, such a simple and labor-saving way, why didn't he think of it?

He was pleasantly surprised by the "mua" on the screen, with a smile on his face and a lot of excitement and joy, and thanked Eva:

"Thank you, dear, hahahaha, you've done me a lot of help this time, thanks to your reminder. ”

"Otherwise, I'm ready to intercept the flow!"

"Let's talk about the specific situation when we meet~"

It's inconvenient on the phone, the KGB has monitors, and if this matter is discovered, it doesn't matter to you.

Eva will definitely be punished -

Helping others hide huge tax sums

Even if you don't get expelled, you will be demoted three levels in a row!

Ling Feng hung up the phone and immediately asked the system to help buy the kind of large oil tanks of twenty fuel tankers from nearby.

Then five more high-power vacuum pumps were bought.

Let the sales manufacturer send it to the farm immediately.

Vera, Feiya, Vajim, and Yuri were all annoyed and complained that they were stupid, why didn't they think of such a simple way?

The six of them hurriedly prepared for work—

All the gold ore was pumped out within today's time.
