- Capacity50KG/24H, 100KG/24H, 250KG/24H (size customised to requirement)
- Size5700 x 1600 x 1100 mm (250KG/24H)
- Electrolysis tank materialPP plate welding reinforcement
- Power supplyHigh frequency pulse rectifier
What This Machine Does
This is the industrial scale machine in the silver refining range, refining 90% purity silver to 99.9% or 99.99%.
Impure 90% silver acts as the anode and a titanium plate as the cathode; dissolved silver redeposits as metal and the silver slag is collected through an oblique bottom electrolytic cell.
It is supplied at 50KG, 100KG and 250KG per 24 hours, and the size can also be built to requirement.
What You Get
- Intelligent electrolysis technology consumes only a small amount of electricity for efficient silver refining, which lowers environmental impact as well as cost.
- Full anti-corrosion design gives long part life and stable operation.
- 9999 high purity silver is extracted more quickly and efficiently.
- Only 10% dilute nitric acid is needed as the electrolyte, which greatly reduces solution cost and is safer to operate.
- Fully automatic operation saves labour and makes the process safer and more convenient.
Who Buys It
- Industrial refiners running continuous silver production
- Mining and smelting groups refining dore silver
- Large recyclers consolidating silver from many sources
- Producers supplying 99.99% silver into industrial supply chains
What It Fixes
- Batch cells cannot support continuous industrial output.
- Traditional chemical refining at this scale means large volumes of acid and large emissions.
- Manual operation at 250kg a day is labour intensive and less safe.
- Slag left in a flat bottomed cell is silver that never reaches the bar.
How It Is Built
- PP plate welded and reinforced electrolysis tank
- High frequency pulse rectifier power supply
- 90% purity silver anode, titanium sheet cathode
- Oblique bottom cell for silver slag collection
- One corrosion resistant circulating water pump
- One stirring and driving device
- Water inlet and outlet piping supplied as a set

Running The Machine
Step
Charge the cell with 90% purity silver anodes and install the titanium sheet cathodes.
Step
Prepare the electrolyte as 10% dilute nitric acid.
Step
Start the circulating water pump and the stirring and driving device.
Step
Run electrolysis from the high frequency pulse rectifier.
Step
Collect the silver slag through the oblique bottom of the cell.
Step
Harvest the deposited 99.9-99.99% silver from the titanium cathodes.
