5 Steps PCB Recycling Process for E-Waste Management and Metal Recovery
PCB recycling is an industrial process that turns waste circuit boards into reusable metals like copper, gold, and silver. Through dismantling, screening, crushing, and refining, it enables efficient resource recovery in e-waste recycling plants and supports the circular economy.
1. Electronic Components Depopulation System
The process starts with PCB depopulation machines that remove components such as CPUs, IC chips, capacitors, and resistors from waste circuit boards. Thermal or automatic desoldering systems reduce material loss and improve recovery efficiency. Processing capacity typically ranges from 200 to 1000 kg/h, depending on system configuration.
2. Components Screening and Classification
Removed components are fed into a vibration screening system to separate materials by size. This step stabilizes material flow and prepares different fractions for downstream sorting in the e-waste recycling line.
3. PCB Crushing and Metal Separation
Bare circuit boards are processed through a double-shaft shredder and grinder, reducing them into fine particles for further separation. Air separation and electrostatic systems then separate metals (copper) from non-metal materials such as resin. Metal recovery rate can reach 99%.
4. Precious Metal Leaching System
High-value components like CPUs and memory modules undergo chemical or electrochemical leaching to extract surface gold layers. Controlled reaction conditions ensure efficient recovery of trace precious metals from e-waste.
5. Precious Metal Refining System
Recovered materials are refined through hydrometallurgical processes such as leaching, precipitation, and electrolysis. Metals, including gold, silver, platinum, and palladium, are purified to ≥99% industrial grade and cast into reusable raw materials.
This complete 5-step PCB recycling process provides an efficient solution for recovering valuable metals from electronic waste while reducing environmental impact.
