Automatic Gold And Silver Electrowinning Recovery Machine
The machine focus on recovering gold,silver,platinum, palladium and rhodium in the plating solution.
The machine also can recovery precious metal ( Au, Ag) from e-waste stripping solution,waste photography developing solution(fixer solution), electronic plating waste solution and gold/silver mine operations (gold leaching solution).
The recovery rate reaches over 99%, and silver with a purity of over 95~99.8% can be directly extracted.
The content of precious metals in the waste liquid after recovery: silver can be lower than 5-20ppm, gold can be lower than 2-10ppm
Working principle
The machine uses a rotating cathode and high-frequency pulse method to electrolytically recover gold and silver ions in the liquid.
The principle of electrolysis is used to reduce precious metal ions in the liquid into metal blocks and adsorb them to the cathode barrel, thereby recovering high-purity gold and silver from the liquid.

Technical data
Machine features and advantages
1. This machine uses rotating cathodes and high-frequency pulses for intelligent electrolytic recycling. It does not add any chemical reagents and only uses a small amount of electricity (150-250w) without the worry of secondary pollution.
2. This machine is small and compact, easy to operate and does not require special supervision.
3. It adopts fully anti-corrosion design and has long service life.
4. The machine has a large processing capacity. After combination, it can process more than 6,000-18,000 liters of silver-containing solution per month, and the treatment volume of gold-containing wastewater is halved.
5. The recovery rate reaches over 99%, and silver with a purity of over 95~99.8% can be directly extracted.
6. The content of precious metals in the waste liquid after recovery: silver can be lower than 5-20ppm, gold can be lower than 2-10ppm.
7. This machine does not require any consumables and electrolysis accelerators, and the operation and maintenance costs are very low.
8. No special tools are needed to remove the silver that been recovered on the surface of cathode, and silver slag with a content of 96~98% can be removed (the content does not include moisture). Silver nuggets with more than 99% can be obtained by burning them directly with a gun.
9. Gold needs to be refined once, because gold is small and easy to spill, which will cause unnecessary waste.
10. The products have been produced on a standardized basis and can also be customized according to customer needs.
