When old mobile phones gather dust in drawers and old computers are sold as scrap, few people realize that the core of these obsolete items—the waste circuit boards—are actually "urban mines" containing copper, gold, and silver. If improperly disposed of, the lead and mercury in the circuit boards can pollute soil and water; if efficiently recycled, the precious metals contained therein could support a green industry chain. The water-based recycling equipment for waste circuit boards is the environmental key to unlocking this mine. The process of this equipment is like a resource sorting technique that balances precision and sustainability. The first step is crushing: the circuit boards are first disassembled into fist-sized pieces by a coarse crusher, then ground into millimeter-sized particles by a fine crusher—this step completely separates metals from non-metallic materials such as plastics and resins. Unlike the crude crushing of traditional methods, modern equipment first removes dangerous components like batteries and capacitors to avoid subsequent pollution. The core water-based separation step is the essence of the "magic". The crushed particles are fed into the water-based separation system, where density differences enable natural sorting: metals like copper (density 8.9 g/cm³) and gold (19.3 g/cm³) are much denser than plastics (1.0-1.5 g/cm³). Under the impact of water flow and vibration beds, the metal particles sink to the bottom, while non-metallic particles float with the water. Through layered screening by jig machines and directional separation by shaking tables, copper, iron, and aluminum can be classified one by one, and even trace amounts of gold can be accurately captured. Unlike the black smoke of incineration and the toxic wastewater of acid washing, the water-based separation process emits no harmful gases, and the wastewater can be recycled after sedimentation and filtration, truly achieving "zero secondary pollution". The separated products have various uses: the metal particles are dried and purified to become high-quality raw materials for smelters; the non-metallic powders are processed into building insulation boards or plastic fillers, realizing full-chain recycling. A set of data suffices to prove its value: a set of equipment processing 10 tons of circuit boards per day can recover 1.5 tons of copper, 300 grams of silver, and 5 grams of gold, equivalent to reducing the mining of 20 tons of copper ore and reducing the landfill of 5 tons of hazardous waste. The significance of this equipment goes far beyond resource recovery. It is a vivid practice of circular economy: it alleviates the pressure of primary mineral extraction and reduces the environmental threat of electronic waste; it is a contributor to the "double carbon" goal: recycling 1 ton of copper emits 80% less carbon dioxide than mining copper; it is a catalyst for green industries: it drives the construction of recycling outlets, equipment manufacturing, and resource reuse in the upstream and downstream sectors. Today, more and more industrial parks are introducing this equipment, transforming electronic waste from a "burden" into a "treasure". In the future, with the integration of AI intelligent sorting technology, the water-based separation equipment will identify rare metals more accurately, further enhancing the efficiency of "urban mining". When the waste circuit boards "spit out" gold in the water-based separation magic, what we see is not only the rebirth of resources, but also the hope of harmonious coexistence between humans and nature.
