Six Machine Families Covering Recovery Refining Polishing And Plating
Recovery machines take dissolved metal out of solution. Refining machines take crude metal to 99.9-99.99%. Polishing and plating machines finish the jewelry that comes after.

Read moreSix Places A Refinery Or Plating Shop Loses Metal
Metal leaves in the rinse water
Drag-out from a plating rack carries gold and silver into rinse tanks on every cycle. A recovery machine on that path deposits it as solid metal instead.
Spent baths sold at waste value
Selling a loaded bath means accepting someone else's assay. Electrowinning it first keeps custody of the metal on your own site.
Crude metal cannot be sold at bullion price
Silver at 80-90% and copper at 60-80% has to be refined. Our cells take both to 99.9-99.99% on dilute acid.
Etchant bought twice
PCB alkaline etchant carrying 100-170 g/L copper is usually sold on. Direct electrolysis recovers the copper and returns the etchant to the line.
Polishing labour caps output
Hand polishing cannot reach dead corners or the metal under set stones. Electropolishing does 80 pieces an hour in K gold and 400 in silver.
Discharge limits keep tightening
Treated solution leaving our recovery machines runs at 5-20ppm silver and 2-10ppm gold.
What The Numbers Behind Our Machines Actually Are
Focused on one machine family
The company is focused on manufacturing precious metal electrolysis recovery machines rather than a catalogue of unrelated equipment.
No reagents in the recovery step
The recovery machines use rotating cathodes and high-frequency pulse electrolysis with no chemical reagent and no accelerator added.
Recovery over 99%
Recovery rate reaches over 99%, with 95-99.8% purity metal taken directly from the cathode.
Low residual metal
Treated solution can be brought below 5-20ppm silver and 2-10ppm gold.
Very low running cost
The recovery machines draw only 150-250W in operation and need no consumables.
Refining as well as recovery
Silver cells from 3kg to 250kg per 24 hours and copper cells from 2kg to 50kg per 24 hours take the recovered metal to 99.9-99.99%.
Standard plus customised
Machines are produced to standard models and can also be built to your solution composition, volume and processing target.

Why Does Silver Need To Be Refined
Raw silver from mines, scrap or recycled material carries impurities that damage conductivity, durability and compliance. This article sets out the five reasons refining is not optional and compares the three refining routes.

Read moreQuestions Buyers Ask Before They Order
If your question is not here, send it by WhatsApp and Amanda will answer it directly.
What does your equipment actually do?
Two things. The recovery machines take dissolved gold, silver, copper, nickel, tin, platinum, palladium and rhodium out of solution and deposit it as solid metal. The refining machines take crude silver at 80-90% or crude copper at 60-80% up to 99.9-99.99% purity.
What recovery rate and purity can I expect?
The recovery machines reach over 99% recovery with 95-99.8% purity metal straight from the cathode. Treated solution can be brought below 5-20ppm silver and 2-10ppm gold. The refining machines produce 99.9% or 99.99% metal.
Do the recovery machines need chemicals?
No. They use rotating cathodes and high-frequency pulse electrolysis without adding any chemical reagent or accelerator, and draw only 150-250W in operation.
What capacities are available?
Recovery machines run from 100-150 L/day on the AC200 to 500-800 L/day on the AC800 of gold-bearing solution. Silver refining runs from 3kg to 250kg per 24 hours and copper refining from 2kg to 50kg per 24 hours.
Can a machine be built for our specific solution?
Yes. The machines are produced to standard models and can also be designed around your liquid composition, processing volume and processing target. The copper recovery machine for etching solution is always built this way.
Where are the machines made and how do I reach you?
They are made by Shenzhen Aicheng Precious Metal Equipment Co.,Ltd in Pingshan District, Shenzhen, Guangdong, China. Contact Amanda, our sales manager, by WhatsApp or email.
