Machines for Recovering Gold from PCBs and CPUs

Electronic waste contains a significant amount of high-value metals, particularly gold, found in printed circuit boards (PCBs) and central processing units (CPUs). To address this high-value recycling demand, we have developed specialized gold recovery equipment that automates the entire process from disassembly to refining, bringing significant economic and environmental benefits to businesses.

Electronic Waste Pre-Processing

First, the scrap PCBs and CPUs are reduced in size and initially disassembled in an automated shredder, effectively releasing the metal and non-metallic materials within. The equipment utilizes low-noise, high-efficiency pulverization technology to minimize dust release and provide material of the ideal particle size for subsequent separation.

Physical Sorting and Metal Concentration

The shredded mixture then enters a multi-stage physical separation system, including magnetic separation, eddy current separation, and gravity separation. This system efficiently separates base metals such as copper and aluminum, while concentrating the gold-containing components. The entire process requires no chemical additives, minimizing the risk of environmental pollution.

Chemical Refining and Gold Recovery

The enriched gold-bearing material enters the chemical refining stage, where gold is dissolved through a safe and controllable hydrometallurgical process. High-purity gold is then extracted through precipitation, electrolysis, and other processes. The equipment is equipped with a recycling system to reduce chemical solution consumption and ensure that wastewater treatment meets discharge standards.

This gold recovery line not only helps companies recover high-value metals and generate substantial profits but also effectively reduces the environmental impact of electronic waste. The equipment's compact design and small footprint make it suitable for recycling companies of all sizes. Processing capacity and process solutions can be customized to meet customer needs.
