Automatic Gold And Silver Electrowinning Recovery Machine For Cyanide And Plating Solution
Unattended electrowinning of gold, silver, platinum, palladium and rhodium from plating and leaching solution
- Target metalsGold, silver, platinum, palladium, rhodium
- Feed solutionPlating solution, cyanide bath, stripping solution, fixer solution, leach liquor
- Recovery rateOver 99%
- Deposit purity95-99.8%
- Residual in treated solutionSilver 5-20ppm, gold 2-10ppm
What This Machine Does
This machine is built for gold and silver electrowinning out of plating solution, including cyanide gold baths.
It also recovers gold and silver from e-waste stripping solution, spent photographic developing and fixer solution, and gold or silver mine leaching solution.
Recovery reaches over 99%, with silver of 95-99.8% purity taken directly from the cathode.
What You Get
- Runs fully automatically, so no dedicated operator stands over it.
- Gold and silver come back as solid metal you keep on site.
- Zero reagent and zero accelerator means no consumable cost and no secondary pollution.
- Treated solution leaves the machine at 5-20ppm silver and 2-10ppm gold.
Who Buys It
- Gold and silver plating shops running cyanide baths
- Mining operations with gold and silver leaching solution
- Electronics refiners with stripping pregnant solution
- Photographic laboratories with spent fixer solution
- Jewelry plating lines wanting to close the loop on drag-out
What It Fixes
- Cyanide gold bath drag-out carries measurable gold into rinse tanks every day and never comes back.
- Leach liquor held in tanks ties up working capital until the metal is actually won.
- Batch chemical recovery needs supervision, reagents and a place to put the residue.
- Wastewater discharge limits are tightened faster than treatment budgets grow.
How It Is Built
- Rotating titanium cylinder cathode with graphite carbon plate anodes
- High-frequency pulse electrolysis for intelligent deposition
- Full anti-corrosion design for long service life in cyanide and acid environments
- Anti-corrosion PLC control system, simple to operate
- Inlet and exhaust valves for controlled filling and air purging
- Exhaust fan supporting continuous round-the-clock running
- Standardised production with customisation available

Where It Is Used
- Gold and silver recovery from cyanide gold plating solution
- Recovery of gold from ore cyanide leaching solution
- Recovery of silver from film water, CP film fixer solution and photo developing water
- Recovery of gold and silver from electronic stripping solution
- Recovery of gold, silver, copper, rhodium and platinum from jewelry plating solution
- Recovery of gold, silver and copper ions from other wastewater
How It Compares With The Alternatives
| Zinc cementation | Consumes zinc dust, produces a cement that needs further refining |
|---|---|
| Carbon adsorption only | Loads the metal onto carbon, which still has to be stripped and electrowon |
| This machine | Deposits metal directly as solid at the cathode with no reagent and 99%+ recovery |
Running The Machine
Step
Open the water inlet valve to feed the solution and open the exhaust valve to release air from the line.
Step
Start the rotating cathode and the pulse rectifier from the PLC panel.
Step
Leave the machine running; the exhaust fan maintains normal operating temperature.
Step
Strip the deposit from the cathode cylinder without special tools.
Step
Melt silver slag directly with a torch to obtain metal above 99%.
Step
Give recovered gold one more refining pass to avoid handling losses on fine particles.

Questions About The Automatic Gold And Silver Electrowinning Recovery Machine
Does it work on cyanide gold baths?
Yes. Cyanide gold plating solution and cyanide leaching solution are both within its working range.
Is supervision required while it runs?
No. The machine is compact, simple to operate and does not require special supervision.
What is the difference between this and the multi-metal recovery machine?
The hardware is the same electrowinning platform. This configuration is set up for gold and silver from cyanide and plating solution, while the multi-metal version is presented for gold, silver, copper, nickel and tin plating baths.
What purity comes off the cathode?
95-99.8%, with silver slag of 96-98% content that reaches over 99% after torch melting.
How large a machine do I need?
Match the model to your daily solution volume: AC200 for 100-200 L/day up to AC800 for 600-1000 L/day.
What does it cost to run?
Only electricity at 150-250W. There are no consumables and no electrolysis accelerator.
