XHF-DJTYJ
Small Silver Stripping Machine
Electrolytic silver de-plating for a workshop bench, 0.5 to 0.8 tonnes of parts a day.
Precious Metal Recovery & Refining Equipment
Stripping, electrolytic recovery, resin adsorption, electrolytic refining and aqua regia dissolution. Between them they cover the whole route from a rejected ring or a tank of rinse water to 9999 silver or cathode copper.
6 machines
The Range
Six machines that take precious metal out of scrap, spent solution and low-grade liquor and hand it back as weighable metal.
10 kg/day
Silver Electrolysis Refining Machine
80 to 92.5 percent scrap silver taken to 9999 on 10 percent dilute nitric acid alone.
99.8% purity
Precious Metal Electrolytic Recovery Machine
High-frequency pulse recovery that pulls gold and silver straight out of spent solution as metal.
3-4 kg/24h
Copper Electrolysis Refine Machine
Scrap copper anodes in at 80 percent, cathode copper out at up to 99.99 percent.
99.9% Ti
Gold Melting Reactor
A sealed 99.9 percent titanium reactor for aqua regia gold dissolution, 10 to 20 kg a charge.
>98% recovery
Gold Resin Recovery Machine
Ion-exchange resin that strips gold out of solutions too dilute for electrolysis.
Who buys this
Who This Equipment Is For
Jewelry factories with their own scrap
Filings, defective pieces, polishing sludge and old stock. The economics change entirely once the metal is refined in-house rather than sold by assay.
Electronics and e-waste processors
One tonne of discarded mobile phone motherboards contains roughly 200 to 350 grams of gold, far above the grade of natural ore.
Plating shops losing metal to rinse water
Drag-out tanks, strip solutions and rinse waters carry gold and silver at concentrations too low to interest anyone and too high to throw away.
Refiners and laboratories
Where the requirement is a documented purity number rather than a recovery percentage.
Why this equipment
What Decides The Choice
The right method for the concentration
Electrolysis on rich plating and strip solutions, resin adsorption below that, aqua regia dissolution for solid gold feed. Choosing wrongly is the most common reason recovery projects underperform.
Published recovery numbers
>=99% on gold and silver electrolytically, >=90% on copper, nickel, platinum and palladium, >98% on resin. Residual silver below 20 mg/L on treated fixer.
Nitric acid only, where possible
The silver refining route runs on 10 percent dilute nitric acid alone, with no waste gas and no high-risk step, and still reaches 9999.
PP and titanium throughout
The two materials that survive this chemistry. Everything wetted is specified for acid and alkali service.
Where it is used
Industries Running These Machines
Electronics And E-Waste Recycling
The urban mine: gold, silver, palladium and platinum recovered from boards, connectors and leach liquor.
Electroplating And Surface Finishing
Bath cleanliness, drag-out recovery and de-plating for plants running precious metal baths.
Jewelry Manufacturing
Electroforming, plating, acid finishing and scrap recovery for factories making gold and silver pieces.
Photographic And Imaging
Silver pulled out of spent fixer at 98 percent recovery, with residual below 20 mg/L.
Precious Metal Refineries
From mixed feed to a documented purity figure: 9999 silver, cathode copper, aqua regia gold dissolution.
