Chapter 10 Electrolytic Silver Extraction
Jiacheng, Zhejiang Province is less than 100 kilometers away from Shenghaiyang Port, and it takes about two hours to drive.

At noon, when it was time for lunch, Tan Jiasheng... the boss of Jiasheng Renewable Resources Recycling came driving a van.

Tan Jiasheng looked like he was in his forties, wearing casual clothes, with a kind smile on his face, he belonged to the kind of person who makes money by being friendly.

After getting out of the car, he enthusiastically shook Lu Xin's hand and started chatting in his native dialect.

After all, they just met each other, so the two exchanged a few simple greetings, and then Lu Xin brought Tan Jiasheng to the warehouse to look at the goods.

When he saw a large pile of copper wires piled up in the empty warehouse, and there was not even an electronic scale in the warehouse, Tan Jiasheng had no abnormal expression on his face. He walked over naturally and checked the location of the copper wires. Fineness comes.

Lu Xin said with a smile: "I just moved here, and the price of copper has risen recently, so I will sell these first, just to make room for the goods..."

Tan Jiasheng nodded to express his understanding, and didn't ask any further questions.

Heroes don't ask where they came from, and cables don't ask where they came from.

What's more, they still run a recycling station. If they don't know how to do it, they can't even get a business license in Shenghai, so there's no need to ask.

"The quality of your copper is very good. It is considered fine copper. I will give you the highest price, 33 a catty."

Lu Xin has also learned about copper prices in the past two days. At 33 a catty, talking about Jiasheng basically only earns gas fees.

"That won't work, let you come all the way here, I can't let you suffer too much."

"It's okay, it's okay! We are fellow villagers, and the first time we cooperate, we should treat it as making friends."

Seeing Tan Jiasheng's insistence, Lu Xin stopped being polite to him.

"Okay, then I'll treat you to dinner later."

Tan Jiasheng smiled and said, "Okay, no problem..."

Tan Jiasheng drove the car into the factory. As a professional recycling dealer, it is necessary to carry an electronic scale with the car.

Then start to weigh, and get on the car directly after weighing.

It took more than an hour to weigh them all, a total of 1473 catties, and a total price of 47136. Erase the leader, 47000.

Lu Xin looked at seven or eight rolls of enameled wire, and simply said, "I'll give you these too. Let's see how much it costs."

Tan Jiasheng heard it and said with a smile, "Okay."

Then he measured the thickness of the insulating layer one by one with an instrument, cut it with scissors, looked at it, and said with a smile: "The quality of these enameled wires is also very good, 20 kg, what do you think?"

This price is also very fair, Lu Xin nodded and smiled, "Okay!"

Then I weighed it again, and it was 380 catties in total, 7600 yuan, and the total price was 54600 yuan.

Tan Jiasheng asked with a smile, "Cash or transfer?"

Lu Xin smiled and said, "Cash, I just need it this afternoon."

"OK, no problem."

Tan Jiasheng is not surprised. People who do second-hand recycling prefer to use cash for transactions in most cases.

Tan Jiasheng climbed into the car, took out a handbag from under the seat cushion, opened it, and took out five stacks of brand new soft sister coins to Lu Xin.

Then he unwrapped another bundle and counted 4600 yuan to him.

"Here, hurry up!"

"it is good!"

When it comes to business, Lu Xin is not polite.

I counted them with the money counter I just bought.

54600 yuan, no more than no less, and no counterfeit money.

"Okay! No problem. Let's go, I'll treat you to dinner."

"Haha, let's go..."

Lu Xin took Tan Jiasheng's truck to the restaurant on the street and had a good meal.

Because Tan Jiasheng was going to drive in the afternoon, all of them drank all the drinks they didn't drink.

Under Tan Jiasheng's deliberate friendship, after a meal, the two of them became brothers.

Tan Jiasheng sent Lu Xin back to the factory, then waved and said, "Brother, I'll go now, let's call."

"Okay. Slow down..."

Lu Xin waved his hand to watch Tan Jiasheng's truck disappear at the intersection, and then hurried back to the factory.

He came upstairs with Wangcai, lifted the quilt, and there were more than 5 yuan.

Lu Xin touched the bright red ticket, collapsed on the quilt and laughed loudly.

The consumption in Shanghai is too high. He has not saved 5 yuan in three years of work, but now he has earned [-] yuan in just a few days.

Seeing that the master was so happy, Wangcai jumped back and forth excitedly.

Lu Xin hugged Wangcai's dog's head and rubbed it vigorously, "I'll give you an extra meal tonight..."

Wangcai stuck out his tongue and licked it.

"Wow...don't lick..."

After arguing with Wangcai for a while, Lu Xin sat up, took out a cigarette from his pocket and lit a cigarette, and gradually calmed down.

Although making money is a happy thing, but in the future, we should try our best to take protective measures before selling.

A few thousand catties of copper is nothing to a renewable resource recycling station, and no one doubts it.

But if you have been selling this high-quality copper wire alone, there will be problems.

So you need to fake it.

For example, if you buy [-] jin of copper from the market, you can buy some of each of them, such as brass, burnt copper, motor copper, and miscellaneous copper, and then mix it with [-] to [-] jin of wire and cable copper to sell. It's much safer.

In addition, try to use cash when recycling materials, and the same is true when shipping, back and forth...

Just as Lu Xin sorted out his thoughts, the phone rang. It was the person who installed the gate. He asked if he was in the factory.

He immediately took the dog downstairs.

There were three people in total, and they quickly removed the door and installed it.

At 03:30 in the afternoon, when the gate was about to be installed, a manufacturer selling electrolysis machines came.

Taking advantage of the time when the manufacturer was moving the machine, Lu Xin went upstairs, and within 5 minutes he came down with a roll of silver-gray wires in his hand.

It is silver-plated copper core wire.

I weighed it on the electronic scale I bought at noon, and it was 9.06 kg.

Next, the on-board technician taught Lu Xin how to install and use it.

"Look, Boss Lu, this is an electrolytic tank. It is used for discharging materials. Just pour in the materials, then pour in the electrolyte, and turn on the switch. After 5 minutes, all the silver plating on the materials will fall off."

"Then the machine will pass through this pipe to pump the electrolyte solution containing silver water into the machine for filtration. The silver will be adsorbed to the silver suction cylinder in the middle of the machine, and the waste water will be discharged from this pipe..."

The operation of the machine is very simple, and it is completely fool-like. It mainly uses test paper to test whether the silver in the wastewater has been extracted. This is a little bit technical.

Soon Lu Xin was able to operate it.

The technician began to introduce the electrolyte again.

"These barrels are electrolytes containing desilvering powder, using a new formula, which does not damage the copper base, especially for copper materials with thick silver plating, and the deplating speed is also very fast."

"The electrolyte can be used repeatedly. The purity of silver is between 99% and 99.9%. There will be no copper and nickel in the traditional electrolytic silver powder. It is cyanide-free, odorless and environmentally friendly..."

After all the explanations, the next step is the actual operation.

According to the technician's instructions, Lu Xin poured the electrolyte solution into the electrolytic tank, then soaked the silver-plated copper core wire from Cyberworld, and activated the electrolytic switch.

The mixer in the electrolytic tank starts to run, so that the electrolyte and the silver-plated copper core wire are fully fused.

The machine stops automatically after 5 minutes.

Lu Xin used a tool to take out the silver-plated copper core wire and took a look. In some places the copper base was exposed, but in other places it was still white, obviously the silver hadn't been removed completely.

Seeing this scene, the technician standing next to him was suddenly embarrassed. He had just vowed that the money on the five-minute material would definitely be refunded, but he was slapped in the face on the spot.

"Uh... this, let me see."

The technician stepped forward to take a closer look, and then asked, "How thick is your coating?"

Lu Xin: "That, 65 microns."

Technician: "... No wonder. With such a thick coating, 5 minutes will definitely not work, at least 15 minutes."

Lu Xin then put the material back into the electrolyte, reset the time, and continued to strip.

After a full 15 minutes, Lu Xin took out the material again.

This time it was different, the copper base inside was completely exposed, and it was shiny, as if it had been washed with water, without any white residue.

The next step is to extract the silver.

The machine extracts the electrolyte solution containing silver water in the electrolytic cell for filtration, and the waste water flows from another pipe to another electrolytic cell, and is extracted and refluxed again, and the cycle is repeated three times.

This time it took about an hour.

Then Lu Xin tested the wastewater with test paper and found that the silver had been extracted.In other words, the silver content in the wastewater is already very low, and the test paper can no longer detect it.

Then Lu Xin took out the two silver suction tubes in the middle of the machine.

The silver suction tube, which was originally bright as new, is now covered with a thick layer of white powdery things, and these are all pure silver.

Put it in a crucible, add a small amount of borax to calcine it, and it will become a silver ingot.

Lu Xin and the technician shoveled all the silver off with tools.

Lu Xin put it on the electronic scale and weighed it. It was 0.89 kilograms in total.

Seeing this number, Lu Xin was pleasantly surprised, but the two technicians were stunned.

What kind of material is this Nima? 9 grams of silver were extracted from 890 kilograms of material, which is nearly one-tenth of the silver content, which is too exaggerated.

Calculated at 5 yuan per gram, it is worth more than 4000 yuan...
