Since silver is a rare earth mineral which exists in limited quantities, it is vital to recover the silver from the old x-rays (radiographs) and other radiology related materials such as fixer solution and silver traps which does contain decent amounts of silver which also makes the silver recovery cost effective as well as saving natural resources. the silver recovered from x-rays is usually reused in x-ray film and many other applications as silver

MoreSilver recovery is the process by which pure metallic silver can be recycled from old x-ray films. The modern process is extremely efficient with a recovery of greater than 99.9% silver. Historically all radiographic film media employed silver salts as part of the image-producing process.

MoreElectrolytic recovery is the most widely used silver recovery method for fixer solution and photographic processing solution. The silver is recovered from solution by electroplating it onto a cathode. A controlled, direct electrical current is passed between two electrodes suspended in the silver-bearing solution.
More02-07-2017 The steel wool will turn black with silver from the fixer. Pick the sw out of the slurry allow to dry. I use a non acid fixer so the liquid can be poured into the septic system. Ages ago an artist friend would smelt use the silver in his work, but these days the small amount I recover is slipped into a zip lock bag stashed in the garage.
MoreSilver Recovery Equipment, Which One is Best for You?

MoreIn processing color films, all of the silver is removed by the fixer to yield a dye image, and so nearly all of the silver is available for recovery. 2) Exposure Level: In processing black-and-white materials, the ratio of exposed and developed silver to soluble silver halide has a considerable influence on the amount of recoverable silver in the fixing bath.
More13-11-2013 For optimum silver recovery, the solution is agitated by a power-driven, rotating cathode. The drum- or disc-shaped cathode is designed of stainless steel to avoid corrosive reactions with the fixer solution and for ease of silver removal. The recovered silver flakes normally run 85

MoreFixing solution is used in the darkroom to fix (i.e. remove unexposed silver) the developed and rinsed x-ray film in conventional radiography.. Components. fixing agent: sodium/ammonium thiosulfate, dissolves unexposed silver; hardener: potassium alum, to harden the gelatin emulsion in film
Moreand X-ray waste. Environmental Concerns Many photographic and x-ray wastes contain silver thiosulfate. Wastes having a silver concentration of 5.0 parts per million (ppm) or more are hazardous because they display the characteristic of toxicity. Wastes that typically contain silver in concentrations greater than 5 ppm include: • Fixer solutions.
