Silver Electrolytic Recovery Machine For Silver Plating Solution
Dedicated silver electrowinning for semiconductor, PCB and jewelry plating lines
- Target metalSilver
- Feed solutionSilver plating solution, e-waste stripping solution, silver ore leaching solution, silver-bearing wastewater
- Recovery rateOver 99%
- Deposit purity95-99.8%
- Residual silver in treated solution5-20ppm
What This Machine Does
This machine is configured specifically for silver ions in plating solution, including semiconductor silver plating, PCB silver plating and jewelry silver plating.
It also recovers silver from e-waste stripping solution, silver ore leaching solution and other silver-bearing wastewater.
Recovery is over 99% and silver of 95-99.8% purity is taken straight off the cathode.
What You Get
- Silver returns as solid cathode metal, ready to melt into a bar.
- Residual silver in treated solution goes down to 5-20ppm.
- No reagent, no accelerator, no sludge to dispose of.
- Compact enough to sit next to the plating line rather than in a separate treatment room.
Who Buys It
- Semiconductor packaging lines running silver plating
- PCB manufacturers with immersion and electrolytic silver processes
- Jewelry factories with silver plating and rinse tanks
- Refiners processing silver-plated electronic scrap
- Wastewater teams that must hit a silver discharge limit
What It Fixes
- Silver drag-out into rinse tanks is invisible on the shop floor and expensive over a year.
- Spent silver baths sold as waste liquid settle far below the metal value inside them.
- Precipitation chemistry turns dissolved silver into a sludge that still has to be refined.
- Discharge testing fails when residual silver in the effluent is not controlled.
How It Is Built
- Rotating titanium cylinder cathode, graphite carbon plate anodes
- High-frequency pulse rectification
- Full anti-corrosion construction
- Anti-corrosion PLC control panel
- Inlet valve and exhaust valve for filling and air purging
- Exhaust fan for continuous operation
- Four standard sizes, customisation available

Where It Is Used
- Silver recovery from semiconductor industry silver plating solution
- Silver recovery from PCB manufacturing silver plating solution
- Silver recovery from jewelry industry silver plating solution
- Silver recovery from e-waste stripping solution
- Silver recovery from silver ore leaching solution and other wastewater
How It Compares With The Alternatives
| Chemical precipitation with chloride | Produces silver chloride that must be reduced and refined before sale |
|---|---|
| Ion exchange resin | Needs regeneration chemicals and the resin eluate still has to be electrowon |
| This machine | Silver deposits directly as metal, 99%+ recovery, residual down to 5-20ppm |
Running The Machine
Step
Fill the tank through the water inlet valve and purge the line through the exhaust valve.
Step
Start the rotating cathode and pulse rectifier at the PLC panel.
Step
Run continuously; the exhaust fan handles heat dissipation.
Step
Strip the silver deposit from the cathode cylinder by hand.
Step
Torch melt the 96-98% silver slag to obtain metal above 99%.
Step
Send the treated solution to the wastewater line or back into the process as your permit allows.

Questions About The Silver Electrolytic Recovery Machine For Silver Plating Solution
Will it work on a cyanide silver bath as well as a nitrate bath?
The machine is presented for silver plating solution generally, including semiconductor, PCB and jewelry plating baths. Send the bath composition with your enquiry so the right model and settings are quoted.
How low can residual silver go?
Silver in the treated solution can be brought below 5-20ppm.
What form does the recovered silver take?
A deposit on the titanium cathode cylinder. Scraped off it is 96-98% silver slag, and torch melting gives over 99%.
Can this machine also take fixer solution?
Yes. Film water, CP film fixer solution and photo developing water are listed application areas for the same electrowinning platform.
Are consumables needed?
No. The machine runs without reagents or accelerators.
What voltage does it need?
All four standard models run on 220V at 300-500W.
