Recently, a “technological breakthrough” has emerged in the circuit board recycling industry! A company in Anhui has applied for a new patent, intriguingly titled “A Device for Hydrometallurgical Recovery of Precious Metals from Waste Circuit Boards”—doesn’t the name alone make you feel like precious metals are calling out to you?
In simple terms, the biggest highlight of this device is: it automatically replenishes the processing liquid without requiring constant human supervision! If the liquid level drops during processing, the system will automatically “refill” it, comparable to a smart coffee machine! This not only improves efficiency but is also more environmentally friendly and energy-saving, significantly reducing the waste of precious metals. So why is everyone researching “circuit board recycling”? Don’t underestimate these colorful circuit boards; they are treasures hiding gold and silver. They contain precious metals like copper, gold, and silver, as well as a large amount of plastic and other metal materials. If discarded directly, it not only wastes resources but also pollutes the soil and water sources. Currently, China generates over 10 million tons of electronic waste annually, with circuit boards accounting for a significant portion. As electronic products are updated more rapidly, the number of old circuit boards is increasing, and this problem will only worsen. How exactly are circuit boards “recycled”? Let’s take a look at a brief introduction!
The recycling process of a waste circuit board is actually not as simple as you might think:
1. Disassembly and classification: First, disassemble electronic components such as capacitors, resistors, and chips.
2. Crushing: Crush the board into granules or fragments to facilitate material extraction.
3. Precious metal extraction: Use chemical liquids (which is the improved aspect of the new patent) to “wash” the metals out of the circuit board.
4. Environmental treatment: Wastewater and exhaust gases must also undergo a complete treatment process to prevent secondary pollution. After all this, what can we do? As professionals in waste recycling, we serve a large number of factories and electronic manufacturing clients, who are the main force in producing circuit boards! Our team has long been recycling including:
• Circuit boards, chips, IC components
• Various types of waste electronic devices, circuit boards
• Copper-containing cables, wires, power modules, and other seemingly insignificant “e-waste”. Through professional sorting and environmental treatment, we not only turn waste into treasure but also reduce pollution and recover more resources. Technology + environmental protection, a promising future! With continuous technological advancements, in the near future, your discarded old computer motherboards may also “transform” into metal raw materials in automated equipment, re-entering the industrial production line. This is the charm of the circular economy!
