Jewelry Manufacturing
Refining polishing and plating equipment for a jewelry factory floor
What Goes Wrong Today
- Old 90% and 925 silver stock cannot be sold or reused at bullion purity without refining.
- Hand polishing cannot reach dead corners, concave gaps or under set stones, and risks stone drop and nail damage.
- Polishing labour is the largest variable cost on high volume silver work.
- Plating rinse water and spent baths carry gold and silver out of the workshop.
What Buyers Ask For
- In-house refining of scrap and old stock
- Batch finishing that covers the whole piece
- A plating bench with several solutions available
- Recovery on the plating rinse line

Read moreQuestions From Jewelry Manufacturing
Which machine should we start with?
Start with the stream that carries the most metal. For jewelry manufacturing that is usually covered by the Silver Electrolysis Refining Machine 3kg Per 24h.
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.
