E-Waste Recycling And Refining
From stripping liquor and plated scrap to refined bar
What Goes Wrong Today
- Pregnant stripping solution from RAM, CPU, PCB and pins is the most valuable liquid on site and the easiest to mishandle.
- Selling loaded liquor on means accepting another party's assay.
- Silver and tin plating on hardware is lost when plated scrap goes straight into a furnace.
- Copper residues carrying gold, silver, palladium and platinum are often sold at copper price.
What Buyers Ask For
- Electrowinning that takes gold out of stripping liquor on site
- A deplating cell that also recovers the stripped metal
- Copper refining that keeps the anode mud
- Silver refining to take recovered slag to 99.99%

Which machine should we start with?
Start with the stream that carries the most metal. For e-waste recycling and refining that is usually covered by the Gold Electrowinning Machine For E-Waste Stripping Pregnant Solution.
Can you size the machine from our figures?
Yes. Send the metal, the concentration and the daily volume and we will confirm the model.
Do you build machines for a specific solution?
Yes. Machines are produced to standard models and can also be designed around your liquid composition, volume and processing target.
What residual metal levels can we expect?
The recovery machines bring treated solution below 5-20ppm silver and 2-10ppm gold.
Do the machines need consumables?
The recovery machines need no reagents or accelerators at all. The refining machines use 10% dilute nitric acid or a sulfuric acid electrolyte.
