Waste PCB is high-value electronic solid waste containing copper, gold, silver and palladium. Traditional recycling methods suffer from low yield and heavy pollution. Henan Yusai Precision Machinery Co., Ltd. offers a professional three-stage PCB recycling solution that combines physical sorting and hydrometallurgy, achieving high-purity separation, maximum resource value and eco-friendly production.
Step 1: Constant-temperature Baking Pre-separation for Initial Material Separation
Professional constant-temperature baking equipment melts solder evenly and separates electronic components from PCB substrates efficiently. This non-damage pre-sorting process accurately divides materials into bare PCB boards and electronic components.
Classified feeding avoids material mixing and ensures high precision for subsequent crushing and precious metal refining.
Step 2: Substrate Physical Crushing and Sorting for High-purity Copper Granules and Resin Powder Purification
Pre-sorted bare PCBs enter the automatic crushing and sorting line. Through crushing, gravity separation and screening, the whole physical processing is pollution-free and stable.
The system fully separates high-purity copper granules and resin powder. Recovered copper granules can be directly sold and reprocessed, while resin powder is reusable as industrial material, realizing 100% PCB material utilization.
Step 3: Component Hydrometallurgical Refining for Efficient Precious Metal Extraction
Electronic components carry concentrated gold, silver and palladium resources, which are the main profit part of PCB recycling. We apply advanced hydrometallurgical refining to replace traditional rough extraction.
Through dissolution, extraction, filtration and high-temperature smelting, precious metals are efficiently refined with high recovery rates, greatly improving overall recycling economic benefits.
Advantages of the Full-process Technology: Eco-friendly, Efficient and Value-maximized
Our integrated PCB recycling technology combines physical separation and hydrometallurgy, building a closed-loop, clean and compliant production system. It effectively solves common industry problems such as incomplete separation and metal loss.
With full recovery of copper, resin powder and precious metals, our equipment maximizes waste PCB value. Henan Yusai Precision Machinery Co., Ltd. provides complete, high-efficiency PCB recycling production lines to help customers achieve higher purity, lower loss and better profits in electronic waste recycling.
