Circuit board waste contains valuable recyclable materials, including copper, aluminum, precious-metal-bearing components, resin, and fiber. A complete scrap refining plant turns these discarded materials into reusable resources through a controlled process of dismantling, crushing, separation, gold stripping, and precious metal refining.

Designed for electronic-waste recycling businesses, this solution can process mixed printed circuit boards from computers, mobile phones, televisions, household appliances, and other electronic products. It supports higher material recovery value while helping reduce environmental pollution caused by improper e-waste disposal.

Complete Solution for PCB Scrap Recycling and Refining

A circuit board waste refining project usually requires more than one machine. The complete plant can be configured as four connected sections according to the feedstock, target materials, capacity, and local environmental requirements:

1. PCB components dismantling
2. PCB crushing and physical separation
3. Gold deplating for gold-plated materials
4. Precious metal refining

This modular design enables operators to select either a full turnkey line or only the processing sections needed for their business.

1. PCB Components Dismantling Machine

Before mechanical recycling, electronic components can be removed from waste circuit boards. The PCB dismantling machine is suitable for separating components from various boards, helping prepare the material for subsequent processing.

This stage is especially useful where boards contain higher-value chip components, connectors, capacitors, or gold-plated parts. By separating these materials first, recyclers can improve the value and efficiency of downstream recovery.

Available capacity options can be matched to project requirements, from smaller operations to larger industrial recycling plants.

2. PCB Crushing and Separating Production Line

After dismantling or direct feeding, waste circuit boards enter the crushing and separation stage. The line is designed to process computer boards, mobile phone boards, TV boards, copper-clad laminates, and similar electronic scrap.

Through size reduction and separation technology, the system separates mixed metallic and non-metallic materials. Recovered metal fractions may include copper and other valuable metals, while non-metal fractions such as resin and fiber can be separated for further treatment or reuse.

For projects requiring high separation performance, the equipment can be configured to achieve separation purity of up to 99%, depending on the raw material condition and plant configuration.

3. Gold Deplating System

Many electronic components contain gold-plated surfaces, including certain CPU parts, connectors, and other high-value components. A gold deplating system is designed to remove and recover gold from these plated materials before deeper refining.

This process helps recyclers handle high-value feedstock separately rather than sending all materials through a single mixed recycling process. The system capacity can be customized according to the reaction tank size and processing requirement, with operation typically managed by a small team.

4. Precious Metal Refining Plant

For material containing precious-metal chip components and anode mud, a precious metal refining plant provides a dedicated recovery solution. It is suitable for recovering and refining gold, silver, palladium, and platinum from electronic waste.

Common feedstock can include MLCC components, memory chips, chip capacitors, northbridge and southbridge chips, and other precious-metal-bearing electronic materials. For gold-plated components, surface gold can first be removed through the deplating stage before the remaining material enters refining.

Depending on the selected model, the plant can be configured for approximately 100 kg/day or 300 kg/day processing capacity. Recovery rates can reach 98–99%, while refined metal purity can reach 99% or above under appropriate operating conditions.

Why Choose a Complete Scrap Refining Plant?

A fully integrated circuit board waste recycling system offers several operational advantages:

• Recover valuable metals from complex e-waste streams
• Improve the handling of copper, precious metals, resin, and fiber
• Configure capacity according to feedstock volume and investment budget
• Combine mechanical processing with precious metal recovery
• Support cleaner, more efficient, and higher-value e-waste recycling operations

Build Your Customized Circuit Board Waste Refining Project

Every e-waste feedstock is different. The ideal scrap refining plant depends on the composition of the circuit boards, expected daily capacity, target recovered materials, available facility space, and local environmental standards.

A customized solution can combine PCB dismantling, crushing and separation, gold deplating, and precious metal refining equipment into one efficient recycling workflow. Contact us with your material type and capacity requirement to receive a tailored equipment configuration and quotation.
