Silver And Tin Electrolysis Stripping And Deplating Machine
Hanging basket deplating cell that strips silver and tin from hardware and electronic scrap and recovers it
- FunctionElectrolytic stripping of silver and tin from plated hardware and electronic waste, with recovery by electrolytic deposition
- Electrolytic cell external dimensions1500 x 1100 x 1000 mm, A-grade 12mm PP plate welding with square steel reinforcement, customisable
- Loading baskets4 pieces, 200 x 650 x 800 mm, effective loading height 700mm
- Washing tank1 set, 900 x 1100 x 1000 mm (length x width x height)
- Rectifier1 unit, three-phase 380V 50Hz
What This Machine Does
This machine electrolytically strips silver and tin from the surface of plated hardware and electronic waste.
The same cell can then electrolytically deposit the stripped metal, so stripping and recovery happen together.
Waste silver acts as the anode and stainless steel as the cathode, with the work loaded into hanging baskets.
What You Get
- Plated silver and tin are taken off the substrate and recovered in the same operation.
- Basket loading means whole batches of parts go in at once.
- The substrate hardware is left available for its own recycling route.
- The stripped electrolyte is filtered, precipitated or electrolysed to give silver slag.
Who Buys It
- Electronic waste processors handling silver plated contacts and connectors
- Hardware recyclers with silver and tin plated components
- Refiners taking in plated scrap from multiple sources
- Operations that currently smelt plated scrap and lose the coating
What It Fixes
- Silver and tin plating on scrap hardware is thin, valuable and easy to lose in a furnace.
- Chemical stripping baths need constant replenishment and produce a loaded solution that still has to be treated.
- Handling plated parts one at a time is too slow for a real scrap flow.
- The stripped metal often ends up in solution with no route back to bar.
How It Is Built
- Electrolytic cell of A-grade 12mm PP plate welding with square steel reinforcement
- Four loading baskets with 700mm effective loading height
- Separate washing tank
- Three-phase 380V 50Hz rectifier
- 316 stainless steel cathode
- One set of cargo hooks supplied
- Cell size customisable to requirement

| Function | Electrolytic stripping of silver and tin from plated hardware and electronic waste, with recovery by electrolytic deposition |
|---|---|
| Electrolytic cell external dimensions | 1500 x 1100 x 1000 mm, A-grade 12mm PP plate welding with square steel reinforcement, customisable |
| Loading baskets | 4 pieces, 200 x 650 x 800 mm, effective loading height 700mm |
| Washing tank | 1 set, 900 x 1100 x 1000 mm (length x width x height) |

| Cathode | 316 stainless steel |
| Anode | Waste silver plated material |
| Electrolyte | Prepared with silver stripping powder |
| Cargo hooks | 1 set |
| Crane | 0.5 ton linear crane, provided by the buyer |
Where It Is Used
- Stripping silver plating from hardware components
- Stripping silver and tin from electronic waste
- Recovering the stripped silver by electrolytic deposition
- Producing silver slag for onward refining
How It Compares With The Alternatives
| Smelting plated scrap directly | Coating metal is diluted into the melt and is hard to recover cleanly |
|---|---|
| Chemical stripping only | Produces a loaded solution that still needs a separate recovery step |
| This machine | Strips and recovers in one cell, with baskets for batch loading and a 316 stainless cathode |
Running The Machine
Step
Load the silver or tin plated parts into the four hanging baskets, which take an effective loading height of 700mm.
Step
Prepare the electrolyte with silver stripping powder.
Step
Lower the baskets into the cell using the 0.5 ton linear crane and cargo hooks; the crane is supplied by the buyer.
Step
Run electrolysis from the three-phase 380V 50Hz rectifier so the plating dissolves into the electrolyte.
Step
Move the stripped parts to the washing tank.
Step
Filter, precipitate or electrolyse the loaded electrolyte to obtain the silver slag.
Questions About The Silver And Tin Electrolysis Stripping And Deplating Machine
What can this machine strip?
Silver and tin plated on the surface of hardware and electronic waste.
Does it also recover the metal?
Yes. The same machine can electrolytically deposit the stripped silver and tin at the same time, and the electrolyte is filtered, precipitated or electrolysed to give silver slag.
How much can be loaded at once?
Four baskets of 200 x 650 x 800 mm with an effective loading height of 700mm.
What power supply is needed?
A three-phase 380V 50Hz rectifier.
Is a crane included?
No. A 0.5 ton linear crane is required and is provided by the buyer. Cargo hooks are supplied with the machine.
Can the cell be built to a different size?
Yes, the cell size can be customised to your requirement.
