<0.1% metal loss in electrolyte sludge
2. Flexible Processing Capabilities
Feedstock Type | Optimal Machine Model | Daily Capacity |
Jewelry scrap/gold dust | PGM-50 Batch System | 1-50 kg Au |
E-waste (PCBs, CPUs) | PGM-500 Continuous Line | 300-500 kg feed |
Anode slimes (Cu/Ni refineries) | PGM-1000 Industrial Plant | 1-5 tons slurry |
3. Eco-Friendly & Cost-Efficient Technology
Closed-loop electrolyte regeneration (eliminates cyanide/nitric acid waste)
70% lower power consumption vs. traditional Wohlwill process
Automated cathode stripping reduces labor by 80%
How Guanma’s Gold Electrolytic Machine Works: Step-by-Step
Stage 1: Feedstock Preparation
Pre-leaching (for e-waste/ore)
Removes base metals via dedicated agitation tanks
Anode Casting
Impure gold cast into 99%+ Au anodes
Electrolyte Formulatio
HCl/chloride-based solution (Au³⁺: 80-120 g/L)
Stage 2: Electrolysis Process
1. Anode Loading
Impure gold plates mounted in titanium anode baskets
2. Cathode Setup
Pure gold starter sheets (or stainless steel blanks)
3. Electrochemical Refining:
Voltage: 0.8-1.2V DC
Current Density: 300-500 A/m²
Temperature: 60-70°C (controlled via inline heaters)
4. Ion Migration:
Au³⁺ moves to cathode → deposits as 99.99% pure gold crystals
Ag/PGM form anode slime for secondary recovery
Stage 3: Product Handling & Recycling
Cathode Harvesting: Automated every 24-48 hours
Sludge Treatment: PGM recovery from anode slimes via separate circuit
Electrolyte Purification: Continuous removal of Cu/Ni impurities
Modular Design
Expandable from 10 kg/day pilot unit to 500 kg/day turnkey plants

Optimizing Your Electrolysis System: Key Questions
Before ordering, consider:
1. Feedstock Analysis
Au/Ag/PGM content? Base metal impurities?
2. Target Capacity
Current vs. 5-year projected volume?
3. Space Constraints
Need compact (20m²) or modular-expandable design?
4. Byproduct Strategy
Will you recover silver/PGMs onsite?
