1. The Past and Present of Extracting Silver from Wastewater and Waste Materials Since the 1980s, farmers in Xianju were individuals at first, and then a few led to the majority, forming thousands of farmers who went out to collect silver from all over the country. Silver’s “three wastes” acquisition army. They traveled to thousands of mountains and rivers, entered thousands of factories and stores, and went through all kinds of hardships to collect all kinds of silver-containing waste fixatives, waste films, expired X-rays, aircraft batteries, and damaged spark plugs and electrical appliances. "Waste" such as contacts and silver-containing scraps from large smelters are collected and processed, and semi-finished "silver slag" is refined and transported back to Xianju. In Xianju, there is a smelting team of tens of thousands of people, who carry out fine smelting and finally produce silver with a purity of 99.99%. In order to obtain silver-containing waste, Xianju people traveled all over the country and went to neighboring countries such as Russia and Vietnam. The large amount of silver refined by farmers in Xianju not only ensures the People's Bank of China's planned purchase, but is also sold to major domestic electronics, refrigeration, electrical appliances, and metallurgical enterprises, contributing to the development of our country's national industry. One of the first people to extract silver from photo studio waste liquid was Wu Jinhuo, a farmer in Sanqiao Village, Chengguan Town, Xianju. It was still in the late period of the "Cultural Revolution", and the rural areas were so poor that there was no way to survive. Wu Jinhuo thought that if he could refine silver from the waste liquid of the photo studio, wouldn't it be a way to make money? He consulted his middle school chemistry teacher, learned the technique, got a bucket of waste liquid, bought some related chemicals, and secretly "refined" it at home. But the first time he didn't refine the silver, he started a fire and almost burned down his house. He was not discouraged and went to consult a capable person again. After changing the ratio and continuing to practice, he finally made a little money. He was greatly encouraged, so he quietly went out alone to Jiangxi, collected various silver-containing waste liquids, processed them on the spot, and refined them into black "silver slag" before taking them back to his hometown for refining. This time when he came back from an outing, he actually produced one pound and two taels of silver. At that time, this was an illegal act and he did not dare to publicize it, so he secretly sold the money on the "black market". The people from Xianju, Zhejiang and Yongxing, Hunan were the first to engage in this business, and now it has a history of 20 or 30 years. In the past, technology was in the hands of Zhejiang people, but now the government has changed. With the development of the economy, coupled with several training institutions' publicity in magazines, newspapers, and the Internet as a way to get rich quickly through bank transfer, the wastewater bank industry has been over-enlarged. 2. Source of raw materials for silver extraction technology from wastewater waste. The wastewater waste here refers to wastewater containing silver, not domestic garbage or wastewater. Common silver-containing wastewater waste includes: waste fixer, bleaching solution, waste photos, film, CT films, Factory, glass mirror factory, thermos bottle factory, mining factory, electronic components factory, film studio, photosensitive material factory. Other silver-containing waste materials include: silver sulfide, silver chloride, silver oxide, silver nitrate, coarse silver, silver powder, electronic factory scrap components, silver contacts, waste silver-plated parts, waste silver paste and other silver-containing waste materials3 , The profit margin of silver extraction technology from wastewater and waste materials is relatively unpopular compared to other industries. If you don’t believe it, if you ask 100 people, not even 1 person will know about this industry. The size of the profit. A lot depends on you. I believe you have seen many reports, including some false reports in magazines. How about tens of thousands of dollars in January when you start, how about making 60,000 in February, and what about thank you letters. Any project, big or small. It depends on many aspects. Including your personal abilities and funds. You can't get rich suddenly in one sentence, but it can make you rich, but it doesn't rule out that you have a lot of liquidity and a wide range of interpersonal relationships. It can be said that it is not difficult to make a lot of money in medium and large-scale units with resources and business networks. Nowadays, some medium-sized printing units in Zhejiang have annual contract costs of hundreds of thousands, and their monthly income is only a few tons. This requires some financial strength to do this. 4. Investment advice on silver extraction technology from wastewater and waste materials Speaking of this sentence, this is the topic that many investment friends are most concerned about. I can analyze it for you like this. This industry does not require equipment or high-tech stuff. Some simple tools can be purchased locally, and some medicines for a few hundred yuan in the early stage of cash withdrawal are enough. The most important thing is to purchase funds, which is the money to collect waste water and waste materials. It is recommended that the working capital be at least 5,000 yuan, because the wastewater you purchased does not sell it immediately after taking out the silver (you should collect the silver and sell it collectively when the amount is larger). If you have more financial strength, you can make it bigger.
5. Suggestions on the operation of silver extraction technology from wastewater and waste. Many friends have read the advertisements in magazines and have the mentality of hoping to get rich. They do not do market research or have no intention of spending high prices to learn the technology (magazine) The advertisements basically talk about an ideal state. To open a company is to train students and charge tuition fees to speculate on technology, and the technology is transferred at a high price. Of course, the authenticity of the technology depends on the unit). Many friends spent thousands of dollars to learn but were unable to see benefits quickly due to various reasons, so they felt very regretful and angry, and also caused some losses to themselves. For those who want to withdraw money, it is recommended to work part-time first. Because many of my friends may not be able to receive a lot of raw materials immediately after learning for various reasons, so working part-time will not delay time or make money. Because doing this does not require a lot of time to operate, most of the time is spent on purchasing raw materials, and raw materials are not produced in large quantities at any time like other things, so we usually go to work and contact the business to collect and process raw materials when we have time. , so that you can make money without wasting time and enrich your time. If you have enough funds and raw materials, there is nothing wrong with doing it exclusively. If you have multiple reasons, then I suggest doing it part-time. The market and raw materials are there, it just depends on how you do it, which is why some people can do it well and some people can't do it well. Today's society relies on competition. No business is done by one person, and pie in the sky will never fall. 6. The general process flow of silver extraction technology from wastewater. For wastewater, test paper is generally used to test the silver content, and then the purchase price is given. The pH value is adjusted according to different waste materials, a precipitant is added to precipitate, and the precipitate is filtered and taken home (filtered The waste water after the process is still lost), and finally the sediment is reduced to extract gold, and the ingot is smelted. With other direct reduction methods (such as reducing sugar method, new biological method, one-step method, etc.), after the purchase price is given, the silver powder mud is directly reduced with a reducing agent, and then taken home to be smelted and cast into ingots. For other silver-containing electronic scrap, acid is used to dissolve the silver from electronic components, then reduced with a reducing agent, and finally smelted into ingots. 7. Which silver extraction technology is better for wastewater and waste materials? There are currently many transfer and training technologies on the market for silver extraction from wastewater, including new biological methods, one-step reduction methods, reducing sugar methods, hydrolysis silver extraction methods, etc. These are basically It belongs to the reducing sugar method. The reducing sugar method has been around for a long time, but now it has been repackaged and improved. Regarding the patented technologies being promoted, everyone on earth actually understands that everyone can apply for a patent. In China, you can actually apply for a patent as long as you are willing to pay the money. This is why foreign countries criticize China for 70-80% of its patents being junk. Another concept to clarify is that there is a difference between a patent application number and a patent number. As long as you apply for a patent, you will have an application number, but not every application will be approved. It takes at least 1 year for a patent application to be approved. If there is a patent number, you should be able to find it on the patent website. There are many ways to extract silver. The key depends on what kind of waste the silver is extracted from, as well as the cost, recovery rate, and operability of extracting silver. Considering comprehensive considerations and practical applications, chemical precipitation is the most commonly used method. There are other electrolytic silver extraction methods. Of course, each silver extraction method has its advantages and limitations. This set of silver withdrawal guide basically contains the above methods of withdrawing silver. 8. How to learn the silver extraction technology from wastewater (fixer solution). It is relatively simple. People who understand basic chemistry knowledge can generally master it after one or two refining times. To extract silver from scrap materials (silver-plated parts, electronic components, etc.), you need to refine a variety of metals. After refining it once or twice, you can basically master the operation essentials, and you can gradually become proficient in it in 2-3 days.
