Gold and Silver Recovery Machines from E-waste
How to efficiently recover precious metals like gold, silver, platinum, and palladium? For small and medium-sized e-waste recyclers, we offer a complete set of commercial-grade precious metal recovery equipment with a processing capacity of 1–1.5 tons per day, making precious metal extraction more efficient, safe, and controllable.
The recycling process begins with the initial disassembly of electronic products. Materials such as discarded motherboards, CPUs, memory modules, capacitors, and IC chips are first fed into an automatic disassembly machine. This separates metal components that can be sold directly from electronic parts requiring further processing. For components with high metal content, like capacitors and plastic-encapsulated elements, specialized recycling machines can further separate reusable materials such as aluminum pellets and plastic pellets.
Process Flow for Extracting Precious Metals from Electronic Waste
Motherboard materials proceed to a crushing and sorting system, where precise mechanical grading effectively separates resin powder from mixed metals. The mixed metals then enter an electrolysis system to extract high-purity copper, laying the foundation for subsequent precious metal refining. Components with higher gold content, such as CPUs and certain PCBs, are processed in dedicated gold stripping equipment. This chemical process removes the gold layer, providing raw material for the precious metal refining stage.
During the refining stage, carbonization furnaces perform pretreatment to reliably separate carbon-based impurities. Materials then enter the precious metal separation and refining system, where specialized processes achieve high-purity recovery of gold, silver, palladium, platinum, and other precious metals. The entire process incorporates a water treatment control system, maintaining a stable pH range of 7-8 to balance environmental safety and recovery efficiency.
The final precious metals produced through this integrated process exhibit high purity and strong market value, serving as a significant profit source for many recycling enterprises. Featuring mature equipment design and a streamlined process flow, this system is ideal for e-waste processing companies seeking to expand capacity and enhance recovery efficiency.
