Automatic Silver Electrolysis Refining Machine 10kg Per 24 Hours
Workshop scale silver cell for 80-90% silver bars and old jewelry
- FunctionRefining silver of 80% to 90% purity to 99.9% or 99.99%
- Capacity10kg/24 hours
- Anode80-90% purity silver in four titanium baskets
- CathodeTitanium cylinder
- Electrolyte10% nitric acid solution
What This Machine Does
This machine refines 80% silver bars or old 90% silver jewelry to 99.9% or 99.99% silver at 10kg per 24 hours.
Silver dissolves from the titanium baskets into dilute nitric acid and redeposits on the titanium cylinder cathode as 99.99% metal.
Gold and copper in the feed separate into the anode mud during the same run.
What You Get
- 99.99% metallic silver obtained quickly without a full industrial electrolysis house.
- Nitric acid consumption and emission are both reduced against the traditional method.
- Anode mud carries gold and copper for separate recovery.
- Zero liquid leakage housing keeps precious metal losses and environmental exposure down.
Who Buys It
- Jewelry manufacturers with a steady flow of silver scrap
- Regional refiners serving local jewellers and pawn shops
- Silverware and tableware factories recycling process scrap
- E-waste operations upgrading recovered silver slag
What It Fixes
- A 3kg cell becomes the bottleneck once scrap volume grows past a few kilos a day.
- Traditional acid refining releases nitric fume and eats reagent.
- Outsourced refining costs a fee on every kilo and returns metal days later.
- Impure silver cannot be sold into bullion or electronics markets.
How It Is Built
- Four round titanium baskets as the anode holder
- Rotating titanium cylinder where refined silver deposits
- 10% dilute nitric acid electrolyte
- Anti-corrosion PLC control panel
- Zero liquid leakage machine housing produced by a special welding method
- Full anti-corrosion construction for long service life

Technical Data
Every figure below is taken from the machine documentation. Where a value is not published it is left out rather than estimated.
| Function | Refining silver of 80% to 90% purity to 99.9% or 99.99% |
|---|---|
| Capacity | 10kg/24 hours |
| Anode | 80-90% purity silver in four titanium baskets |
| Cathode | Titanium cylinder |
| Electrolyte | 10% nitric acid solution |
| Working voltage range | Adjustable CV 1.6V-4V |
| By-product | Anode mud containing gold and copper |
| Control | Anti-corrosion PLC panel |
| Housing | Zero liquid leakage welded construction |
Where It Is Used
- Refining silver bars of 80-90% purity to 99.9-99.99%
- Refining old 925 and 90% silver jewelry
- Upgrading silver slag recovered from plating solution
- Recovering gold and copper from the anode mud as a second stream
How It Compares With The Alternatives
| 3kg/24h machine | Same chemistry and construction at a smaller daily throughput and CV 5V-8V |
|---|---|
| 50kg/24h machine | Titanium plate cathodes, sloped bottom cell and electrolyte filtration, 380V three phase supply |
| This 10kg/24h machine | Titanium basket and cylinder configuration at workshop scale, CV 1.6V-4V |
Running The Machine
Step
Check that every screw is tight, that the titanium basket bag is undamaged, and that the inlet and outlet valves are closed.
Step
Prepare a 10% dilute nitric acid electrolyte.
Step
Distribute the silver nuggets evenly across the four titanium baskets and pour in the acid until the charge is covered.
Step
Switch on the power and set the adjustable voltage CV between 1.6V and 4V; the current follows and needs no separate adjustment.
Step
Start the electrolytic stirring switch.
Step
Replace the electrolyte based on feed purity: once per refining for impure silver, several reuses for clean high grade silver.

Questions About The Silver Electrolysis Refining Machine 10kg Per 24h
How does this differ from the 3kg machine?
Same working principle and construction at a higher daily throughput. The adjustable voltage range on this model is 1.6V-4V rather than 5V-8V.
Can it refine 925 sterling silver?
It is specified for 80-90% purity silver bars and old silver jewelry. Send your feed assay with the enquiry so the right model is quoted.
What do I do with the anode mud?
It contains gold and copper separated during refining and is processed separately to recover them.
How pure is the silver on the cathode?
99.9% or 99.99% metallic silver.
Does the machine leak?
The housing is welded by a special method for zero liquid leakage, which minimises precious metal loss and environmental contamination.
What maintenance does it need?
The machine is simple to operate and maintain, with a full anti-corrosion design for long service life.
