If reverse electrolysis were possible you'd be much better off buying silver plate at flea markets, auctions, scrap yards and reclaiming that as opposed to x rays and such. There are many videos on youtube about reclaiming silver from everything from keyboards to xrays.
Actually, recovery shouldn't be that big a pain once the cathode is plated. If my memory is correct silver melts at about 1100 farenheit. A simple adjustable bullet casting pot should be hot enough. Throw in a handful of your silver coated anodes and let the silver melt off.

Using the electrolysis coupled elution process by a Ni cylinder working electrode and during nearly the same time (10–12 h), it was possible to remove about 95% of silver from Lewatit M 504 and about 70% of silver from Lewatit M 500. A more negative potential was used for the electrolysis process of the loaded silver from Lewatit M 500.

Ion exchange was more than 99% efficient in silver recovery from the radiographic fixer and resulted in an 80% reduction in biochemical oxygen demand and a 95% reduction in chemical oxygen demand.
bilized, silver recovery from high-silver ore would be difficult. Similar methods were used by Scheiner (8-10) to extract silver and other metals-from a complex sulfide concentrate. These methods re quired a C1 2-02 or FeC12-02 leach at ele vated pressure and temperature to form insoluble lead and silver …
India plans to hold green hydrogen auctions as part of a broader plan to curb greenhouse gas (GHG) emissions. The government is planning to use 2,000 mega-watt (MW) solar and wind power capacity for hydrogen production. Apart from industrial use, hydrogen technology can also be used to store electricity and potentially to run vehicles. Plans […]
Silver-recovery performance (measured by the efficiency of silver-ion removal from the solution during electrolysis) was evaluated for each level of constant operating current. The data was used to determine the effects of operating current on process performance, and to calculate the charge dose as a scale-up and operating factor.
There is a right way and a wrong way, but it depends on the coin. Silver coins, when found in the ocean, will have an encrustation that is typically blackish in color. This is because salt water corrodes silver. And any artifact found in salt water, has to intially stay in salt water until it is conserved.
The electrochemical equivalent of silver (atomic mass = 108), Z Ag = 108/96500 = 0.001118 gm/coulomb. This law was used to construct the instrument Coulometer to determine the amount of electricity passing through the circuit by determining the quantity of substance decomposes at an electrode in electrolysis solution.. Avogadro number calculation. In learning chemistry, Faraday's …
I was considering using electrolysis to recover silver from industrial fixer solution. The 100 gallons of fixer solution has about 8-10g ag per liter. i will be processing 100 gallons at a time. I am wanting to use electrolysis because we are required by the city to get the silver content down...
Most circuit boards contain all sort of precious metals: Gold, Silver, Palladium and sometimes Platinum. All circuit boards contain base metals: Copper, Nickel, Aluminum, Zinc, Tin, Lead and Iron. As well, small amount of hazardous elements like Beryllium, Barium and others that has to be considered while processing scrap circuit boards. To get ...

Silver-plated items are usually worth less than those made of sterling silver. Sterling silver is 92.5 percent pure silver, whereas silver-plated items have a thin layer of silver on top of another material, such as copper or nickel. Silver plating is a technique that dates back hundreds of year. That means that early ...
There're various kinds of silver electrolysis units available in the market. I would recommend you opt for the latest ones, since they offer higher silver extraction rates. A good unit can cost anything from $6,000 to $100,000 depending on the size, capacity and make.
The result shows silver recovery increases with increase in protein concentration, 5.4 mg of pure silver can be recovered from 600 mg of waste X-rays film at most favourable condition of protein concentration 0.2857 mg/ml; temperature 45 °C, pH6.5 and stripping time 20 min.
Cyanide silver solution containing 200 to 1000 mg L2 1 silver ions were used for recovery studies. The nature of the silver deposit was studied using a Hull cell, and the current density range was selected for electrolysis to recover silver.
