When smartphones, computers, and other electronic devices are updated and replaced at a rate of hundreds of millions of units per year, waste circuit boards (PCBs) are becoming silent "two-sided mines" in cities—each ton of PCBs contains 200 grams of gold, 10 kilograms of copper, and 3 kilograms of silver, with a value comparable to that of natural mineral deposits. However, due to the presence of toxic substances such as lead and mercury, improper disposal of PCBs can turn into "invisible bombs" for soil and water. How to resolve the conflict between "resource treasure" and "environmental threat"? Water-based selection equipment for recycling waste PCBs is opening up new doors for the resource utilization of electronic waste with its green and efficient technology. In the past, incineration methods extracted metals but released dioxins, and chemical leaching caused heavy metal pollution. However, water-based selection technology achieves zero emissions and high recovery through its physical wisdom of "using water as a medium". The core logic is density difference: crushed PCB particles are put into a water medium, where metals (copper, gold, etc.) with high density sink, while plastics and resins with low density float, separated by scrapers or overflow devices. This purely physical process not only avoids secondary pollution from chemical reagents but also preserves the original quality of metals. This set of equipment is not a single machine, but an integrated system covering pre-processing to purification. First, coarse crushing and fine grinding disassemble PCBs into uniform particles; vibratory sieving classifies different-sized particles to ensure water-based selection efficiency; the core water-based selection tank adjusts water flow speed and tank angle to enable precise stratification of metals and non-metals; separated materials are dewatered and dried before being purified by magnetic and electrostatic selection, ultimately yielding copper powder, gold particles, and other products with a purity of over 95%. The modular design transforms the recycling process from "fragmented" to "standardized", with an efficiency increase of over 30%. At a certain recycling plant, this equipment processes 500 tons of waste PCBs annually, recovering 40 tons of copper and 100 kilograms of gold, creating economic benefits while reducing the burial of thousands of tons of toxic waste. Compared with traditional processes, the resource recovery rate increases by 15%, and the entire process only requires recycled water, with no emissions of waste gas or wastewater. It not only reduces the enterprise's environmental protection costs but also aligns with the circular economy policies under the "carbon neutrality" goal, making the development of "urban mines" sustainable. The water-based selection equipment for recycling waste PCBs is a vivid interpretation of technological innovation in resource recycling. It transforms electronic waste from an environmental burden into a recyclable "urban mineral", and water from the source of life into a green link carrying golden resources. On the path of sustainable development, such "green codes" are helping us unlock more possibilities for the harmonious coexistence of resources and the environment—letting every piece of waste PCB be reborn into the golden hope that illuminates the future in the rhythm of water.
