With the accelerating pace of electronic product replacement, the global annual volume of discarded printed circuit boards (PCBs) is growing exponentially. These discarded PCBs contain precious metals such as copper, gold, and silver, as well as hazardous substances such as lead and mercury. Currently, my country's PCB recycling rate is less than 20%, and a large number of discarded PCBs are improperly handled, resulting in not only a waste of resources but also a serious environmental threat. Traditional treatment methods, such as incineration and acid leaching, pollute the environment and hinder efficient resource recovery.

To address the challenges of PCB recycling, a new generation of intelligent separation equipment utilizes multi-stage physical sorting technology to achieve efficient and environmentally friendly recycling. Core equipment includes a coarse crusher, a fine crusher, a high-voltage electrostatic separator, and an eddy current separator, forming a complete processing line. These equipment utilizes a modular design, allowing process parameters to be adjusted for different PCB types, achieving a metal recovery rate exceeding 98%. Compared to traditional methods, the new equipment produces no secondary pollution and reduces energy consumption by 40%.

The modern PCB separation process consists of three key steps: first, mechanical crushing breaks the PCB into uniform particles; second, high-voltage electrostatic separation utilizes differences in material conductivity to separate metals from non-metals; and finally, gravity separation and eddy current separation further purify the metals. Some high-end equipment is equipped with intelligent recognition systems that automatically distinguish between PCB materials, enabling precise sorting. The entire process takes place in a closed environment, equipped with comprehensive environmental protection facilities to ensure safe production.

PCB separation equipment offers significant economic benefits. For example, processing one ton of waste PCBs can recover 300 kg of copper, 0.5 kg of gold, and other precious metals, with a direct economic value exceeding 20,000 yuan. Furthermore, compared to traditional mining and smelting, metal recycling can save 85% of energy and reduce carbon emissions by 65%. With rising global precious metal prices and increasing environmental protection requirements, the payback period for investing in PCB recycling equipment has been shortened to one to two years. Furthermore, the industry enjoys preferential policies such as immediate VAT refunds, promising promising development prospects.

Driven by the "dual carbon" goals, the PCB recycling industry is experiencing rapid growth. my country's recycling equipment market is projected to exceed 5 billion yuan by 2025. In the future, equipment will be upgraded to more automated and sophisticated features, with technological innovations improving sorting efficiency. This industry will become a key component of electronic waste resource utilization, contributing to green and sustainable development.
