Silver Electrolysis Refining Machines
These machines use the principle of electrolysis to refine crude silver of 80-90% purity to 99.9-99.99% purity silver. Gold and copper in the feed separate into the anode mud during the same run.

View machineWhat This Category Is For
Crude silver from scrap, jewelry or recovered slag cannot be sold at bullion price. Traditional nitric acid refining consumes acid, emits fume and gives no automatic control, while outsourced refining costs a fee and a loss allowance on every kilo.
Who It Suits
- Jewelry manufacturers with silver scrap
- Regional and industrial refiners
- Bullion producers
- E-waste operations upgrading recovered silver
Why These Machines
- Output at 99.9% or 99.99% metallic silver
- Four capacities from 3kg to 250kg per 24 hours, with other sizes customised
- Only 10% dilute nitric acid as the electrolyte, reducing both cost and emission
- Gold and copper recovered separately from the anode mud
- Zero liquid leakage welded housings on the workshop machines and automatic scrapers on the production machines
Where These Machines Are Used
- Refining 80% silver bars to 99.9-99.99% silver
- Refining old 90% silver jewelry to investment purity
- Refining silver bars of 80-90% purity to 99.9-99.99%
- Refining old 925 and 90% silver jewelry
- Refining 925 sterling silver jewelry to 99.99% silver
- Refining 80% silver bars and granules
- Continuous industrial refining of 90% silver to 99.99%
- Refining of dore silver from smelting operations

How These Machines Are Configured
Questions About Silver Refining
What input purity does the machine need?
80% to 90% purity silver, whether as bars, nuggets or old jewelry.
What purity comes out?
99.9% or 99.99% metallic silver deposited on the cathode cylinder.
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.
Can it refine 925 sterling silver directly?
Yes. 925 sterling silver is used as the anode and refined to 99.9-99.99% silver.
How much silver can be charged at once?
50 to 200 kg of scrap silver, in a bath of approximately 500 litres.
