"Precious metals containing gold and silver? Why do you ask about this? Could it be that you want to collect rags too?" Huang Yunzhi joked.

"Hahaha, if Gouwa cannot receive the loofah water, the big tricycle will be idle. You can collect rags. Tsk, Yunzhi, you have to be careful. Gouwa is so smart. If he collects rags, he will not have the share of you." Jiang Xiaoe said with a smile.

Huang Yunzhi looked alert.

"Uncle Eight, even if I collect rags, I will make it bigger, instead of collecting them everywhere." Huang Yi smiled, "I just want to know about the waste products containing gold and silver."

"Yes, you are a person who makes a lot of money, so how can you look at the small business that makes dozens of dollars a day?" Huang Yunzhi smiled, "Gouwa, I don't know much about this when you ask me this. After all, I just collect iron and paper. However, I know that there is a type that should contain gold and silver. I heard that if someone takes it back, it will be used to refine gold."

“What is it?”

"Mobile phones, I wanted to do the mobile phone repot business before, but it didn't work. The cost was a little high. I heard that these phones can be disassembled and sold second-hand accessories. If they can't be sold, they will use them to refine gold. It seems that there is gold on the motherboard, and I don't know whether it is true or not." Huang Yunzhi said.

"Uncle Ba, do you know someone who collects old phones?"

"I know."

Huang Yi asked him how many phone calls he had taken.

He opened the search software immediately.

Enter: Refining gold on your mobile phone.

A lot of information pops up.

He clicked in one by one and gained a lot.

Through this information, he learned the basic knowledge of refining gold on mobile phones.

It is said that mobile phone motherboards, chips, cables, battery contacts, mobile phone cards, etc. all contain precious metals.

Because precious metals can improve mobile phone performance.

"Wonderful, in this era of information explosion, I can learn a lot of knowledge from the Internet, and in the future I still have to get used to using search engines on my phone."

He entered again: waste containing precious metals.

A lot of information popped up again.

There are many waste materials with extraction value, the most common one is electronic metal waste.

There are also wastewater from electroplating plants, waste mud, gold-containing wastewater from circuit board plants, waste from jewelry plants, etc.

"Then what wastewater and mud, don't think about it. This thing has complicated ingredients and has no place to put it in. Transportation is even more difficult and it is troublesome to refine. I can't compete with other people's refineries for the waste of jewelry factories, but the old mobile phone industry is good."

"According to the refining method mentioned online, this cost is too high. Besides the acquisition cost, I almost don't have to spend the refining cost. I just eat more to replenish my energy, which is very competitive."

He went home immediately, rummaged through the cabinets, and found a Nokia elderly machine he used before.

He disassembled it and used the Five Elements Qi-seeing Technique.

Suddenly ecstatic.

The motherboard does contain gold and silver, some metal materials with a density comparable to gold, and some earth-attribute materials with extremely high quality.

"Wonderful, a motherboard is so rich and colorful. Modern technology is indeed powerful. Moreover, most of the materials are very pure and clearly divided. Only a small number of them are integrated. It should not be very troublesome to separate them."

Yaya... the little guy hugged his thighs, a little angry and a little aggrieved.

"Haha, Xiaowei, is it good to perform a magic trick for you?" Huang Yi smiled.

When no one was around, he called himself a father in front of Huang Youwei.

Baaaaa...the little guy looked curious.

Huang Yi put the motherboard in his hand and used the five elements rings that were invisible to the naked eye.

Slowly, the motherboard gradually melts and turns into various particles.

Yayayaya... the little guy widened his eyes and was very excited.

Huang Yi also looked ecstatic, "This is gold wire, silver beads, copper beads... and many other materials that I don't know."

Although there are very few golden threads, they can accumulate into more.

"According to what is said online, a ton of old mobile phone can extract hundreds of grams of gold, and the world's best gold mine can only extract 50 grams of gold per ton. This old mobile phone is simply a rich mine, but I don't know how much it costs."

He has to go and recycle it himself.

If it's cost-effective, he will do this business.

He held the little guy from door to door to find his old phone.

"Gouwa, are you... recycling your old phone?" Lin Xiaoying widened her eyes.

"Dog kid, why bother? If you don't make a big money, why do you make such a small amount of money? How much money can you make when recycling your old phone?"

"It's okay, as long as it's a serious business, I will do it." Huang Yi said, "Aunt San, please bring me your old phone. I can give it to you, or I can buy some dishes and come back to the kitchen knife, and I will give it to you."

"Hey, what's the useless old mobile phone worth? You made us make so much money and brought us a loofah planting project. This old mobile phone will be given to you." Lin Xiaoying said.

She immediately went into the house and took out six old mobile phones, four of which were very old old mobile phones, and two of which were flip machines.

"Thank you then."

Huang Yi picked up his phone and left, looking forward to it.

"Xiaoying, we are sinners and have become accomplices of Jiang Xiaoe and others. Let's see, if you force such a good young man to this point, you will start a rag business." Huang Ruifa said.

"Dad, that's not right. Gouwa seems to be quite rich. He has contracted a reservoir now. I guess he really has a way to do this." Lin Xiaoying said.

"What money do you have? I heard just now that Tang Yun asked someone to help design a house. I guess he was helping the house to help Gouwa get it. How could he have enough money?" Huang Ruifa said.

"Dad, everything has happened, so don't talk about it anymore. In the future, if the dog baby is poor again, let's help more." Lin Xiaoying said.

Huang Yi went to other people's home to collect old mobile phones.

Everyone looked at him with sympathy. Seeing his joyful look after getting his old phone, he felt very uncomfortable and ashamed.

Alas, what an energetic dog before.

Even though he could fight Zhao Hu and Jiang Xiao'e, he dared to slap Lin Hui in the face, but these people actually forced him like this.

Because he was kind-hearted, filial, kind-hearted, and was afraid that everyone would cause trouble in the future, he had to agree to contract the land to the collective.

They felt ashamed, so they didn't charge Huang Yi's money at all, and even gave Huang Yi all the old mobile phones at home.

He even wanted to give Huang Yi all the valuable junk at home.

Almost every household has more than three old mobile phones, but this time I collected 600.

After returning, Huang Yi went to the street and bought two electronic scales first. One was more accurate and the other was not that high, but it could be weighed heavier.

When you get home, you will immediately disassemble your phone, use the Five Elements Ring, and refine the metal.

Until the evening, he separated all the metal accessories of the six hundred mobile phones.

Then melt the same metal into a ball with the five elements rings again.

A total of fifty or sixty different materials were obtained.

He doesn't care about anything else, mainly caring about gold and silver.

He widened his eyes when he placed the gold beads on a high-precision electronic scale.

"Damn it, as mentioned online, an old flagship phone contains at most 0.03 grams of gold, and an ordinary phone has about 0.02 grams, 600 pieces, that's more than ten grams. Why is this so much? Could it be that the electronic scale is broken, right?"
