Waste circuit board detection, waste circuit board recycling, and waste circuit board refining technology are technologies that benefit the whole industry. The sources of raw materials available are endless. There are many materials that can extract gold from electronic waste, such as Common waste computer motherboards, CPUs, memory sticks, sound cards, graphics cards, network cards, waste mobile phones, printers, VCDs, DVDs, communication circuit boards, televisions, digital electronic products, refrigerators and washing machines, game consoles, learning machines, MP3, MP4, etc. Many materials include precious metals such as gold and silver. A ton of ore can extract several to dozens of grams of gold, while a ton of electronic waste can extract about 900 grams of gold, 1,500-3,000 grams of silver, 60 grams of palladium, 130 kilograms of copper, and some tin. Nickel, and other metals. With the upgrading of electronic products, the amount of scrapped electronic products is increasing year by year. Wasted electronic waste can be found everywhere. Just contact major scrap collection stations, repair shops, and electronics factories. Have a lot of resources immediately. The cost of recycling it is much lower than that of extracting it from raw ore, and the economic benefits are very obvious.

In addition, the external materials and internal metal components of many waste electronic products can be reused to generate greater value. Therefore, a lot of electronic waste is a small “gold mine”. It is an inexhaustible gold mine that will never be exhausted.

Gold has always been a universal hard currency that maintains value in the world. It has no shelf life and is a product that can never be sold. Gold stores of all sizes across the country buy it in cash. If gold is found in waste circuit boards, it can be refined and sold for money. It is dizzying to look at the various investment projects currently on the market, but there are not many that actually require little investment and high benefits. The technology of extracting gold and silver from waste circuit boards is really rare in the market, and it can be regarded as an unpopular get-rich-quick project.
