A gold recovery refining system is a technical solution designed to separate and recover gold from plating sludge, spent electroplating solutions, electronic components. PMAC helps businesses optimize raw material costs, reduce hazardous waste, and comply with environmental regulations in Vietnam.
I. Definition
1. What is metal refining recovery?
Metal recovery refining is the process of separating, recovering, and refining valuable metals from metal-bearing sources generated in industrial production, such as plating sludge, spent electroplating solutions, electronic components, and metal scrap.
The objective is to reclaim metals especially precious metals for reuse in manufacturing or commercial applications, while reducing hazardous waste generation and lowering environmental treatment costs.
2. Gold recovery refining system
A gold recovery refining system is an integrated combination of equipment, chemicals, and technical processes designed to separate, recover, and refine gold from gold-containing sources generated in industrial production, such as plating sludge, electroplating solutions, electronic components, and gold-plated scrap.

This system plays a critical role in optimizing raw material costs, improving recovery efficiency, and meeting environmental, sustainability, and ESG compliance requirements.
II. Operating principles
A gold recovery refining system operates on the principle of selectively separating gold from metal-bearing materials or solutions through controlled chemical, electrochemical, and physical processes. This approach enables gold to be recovered in a form suitable for further refining and reuse in manufacturing.
The system does not create new gold; instead, it recovers gold that already exists in industrial waste streams or metal scrap.

The steps involved in precious metal recovery using a refining recovery system include:
– Step 1: Collection and Pre-treatment of Materials
– Step 2: Gold Separation (Refining) Stage
– Step 3: Gold Recovery from the Refining Solution
– Step 4: Refining and Purity Enhancement
– Step 5: Waste Treatment and System Recirculation

III. Gold stripping chemical gold tripper 647
1. High gold recovery efficiency
It is capable of stripping and dissolving up to approximately 20 g of gold per liter of solution within just 20 seconds to 1 minute.
The process delivers high recovery efficiency without electrolysis, remains stable during operation, and is suitable even for thin gold-plated layers, minimizing precious metal loss during processing.
This enables businesses to maximize the value of recovered gold while optimizing raw material costs.
2. Safer than many conventional chemicals
Tripper 647 is considered safer because it does not contain cyanide as an active ingredient. However, during operation, a KCN additive may be required as part of the process.
This significantly reduces the generation of toxic gases during gold stripping and allows occupational safety risks to be more easily controlled when the system is operated in accordance with proper procedures.
3. Easy to use and flexible for multiple production scales
Gold Stripper 647 is suitable for a wide range of application scales, from small precious metal recovery workshops to industrial production lines in electroplating, electronics, and semiconductor industries.
The chemical does not require complex equipment, integrates easily into existing systems, and allows capacity expansion based on actual production needs.
This flexibility makes Gold Stripper 647 an optimal solution for businesses seeking to improve gold recovery efficiency while maintaining effective control over investment costs.
IV. Applications of gold recovery refining in manufacturing
1. Electronic components and semiconductor manufacturing
In the electronics and semiconductor industries, gold is an irreplaceable metal due to its excellent electrical conductivity, strong oxidation resistance, and superior long-term stability.
The refining process separates and purifies gold from gold-plated components, chip leads, connectors, PCB boards, and bonding wires, allowing it to be directly reused in manufacturing.
Recovered gold meets the technical purity requirements of modern electronic production processes, helping businesses reduce dependence on virgin gold, stabilize raw material supply, and optimize production costs.

2. Industrial and decorative electroplating
In the electroplating industry, gold is used for electrical contacts, corrosion-resistant coatings, and high-end decorative finishes. Gold recovery refining enables businesses to recycle gold from depleted plating solutions, plating sludge, and defective plated parts, returning gold to the production cycle.
Applying refining recovery in electroplating not only reduces the cost of chemicals and precious metals but also improves control over plating quality while better meeting environmental regulations and industrial waste treatment requirements.

3. Medical devices and high tech manufacturing
High-purity gold is widely used in medical devices, biosensors, and advanced technology products where strict requirements for purity, stability, and material safety apply. Through gold recovery refining systems, businesses can reuse gold that meets technical standards for high-precision components.
This approach helps reduce raw material costs while ensuring compliance with stringent regulations in the medical and high-tech industries.
4. Jewelry manufacturing and precious metal craftsmanship
After recovery refining, gold is further purified to the required level and then alloyed to achieve the desired gold grade for jewelry manufacturing.
Applying refining recovery allows jewelry producers to secure a stable raw material supply, reduce the cost of sourcing virgin gold, and enhance production sustainability, while still ensuring the value and quality of the final products.
