Photographic And X-Ray Film Processing
Silver recovery from fixer solution film water and developing water
What Goes Wrong Today
- Fixer solution carries dissolved silver that is invisible until it is measured.
- Small volumes accumulate across many sites and are easy to discard.
- Discharging silver-bearing solution creates a compliance exposure.
- Outsourced silver recovery from fixer returns little of the metal value.
What Buyers Ask For
- A compact recovery unit for fixer and developer solution
- Residual silver low enough for discharge
- No reagent handling
- Recovered silver in a form that can be refined

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 From Photographic And X-Ray Film Processing
Which machine should we start with?
Start with the stream that carries the most metal. For photographic and x-ray film processing that is usually covered by the Silver Electrolytic Recovery Machine For Silver Plating 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.
