Traditional manual and semi-automatic metal purification processes suffer from low efficiency, unstable purity, high labor costs and low recovery rates. To solve these industry pain points, our fully automatic precious metal electrolytic refining production line integrates mature gold & silver and copper & nickel electrolysis technologies. Designed for secondary metal recycling, the automated system delivers stable, high-purity metal output and high recovery rates for various waste metal materials, ideal for modern large-scale recycling factories.
1. Application Scope
Featuring a modular structure, the production line supports independent or combined operation of gold-silver and copper-nickel refining units. It is widely applicable:
-
Processed Metals: Gold, silver, copper, nickel and other precious and non-ferrous metals
-
Raw Materials: Waste PCB metal layers, electroplating wastewater, waste alloys, metal scraps, smelting tailings and other metal-bearing wastes
-
Applicable Industries: Precious metal recycling plants, e-waste treatment factories, electroplating enterprises and metallurgical processing plants
2. Standard Purification Process
The whole production workflow is fully automatic and closed-loop, covering raw material processing to finished metal collection with minimal manual intervention.
2.1 Raw Material Pretreatment
Solid waste materials are sorted, crushed and cleaned to remove impurities, oil and non-metallic residues. Liquid materials such as electroplating wastewater are filtered and precipitated in advance. Stable pretreatment ensures high-efficiency and high-precision electrolysis.
2.2 Intelligent Electrolyte Conditioning
The system automatically configures and adjusts electrolyte concentration, pH value and temperature according to different metal characteristics. Real-time monitoring and automatic liquid replenishment maintain a stable electrolytic environment and consistent purification quality.
2.3 Automatic Core Electrolysis
Equipped with an intelligent gantry transmission system, the equipment automatically completes tank loading, electrolysis and plate shifting.
Gold & Silver Refining: Precisely separates and enriches gold and silver ions to produce high-purity precious metals.
Copper & Nickel Refining: Adopts potential difference electrolysis technology to realize accurate separation of copper and nickel, solving the difficulty of mixed metal purification.
Automatic control of temperature, current and pressure ensures stable and efficient electrolytic reaction.
2.4 Secondary Refining & Finishing
Electrolytic precipitated metals are stripped and secondarily refined to remove trace impurities for higher purity. Finished metals are cleaned, dried and collected through standardized procedures with complete appearance and stable quality.
2.5 Waste Liquid Recycling & Environmental Protection
The closed-loop waste liquid recycling system reduces electrolyte consumption and production costs. All waste water and residues are treated up to standard, meeting global environmental protection requirements for green production.
3. Core Equipment Advantages
