Ok, that makes sense. Recovering the lost silver would be easy. Incinerate the filters, screen, remove any magnetic particles, digest with nitric acid. Recover the silver with copper. It might be more involved than that, depending on what else might be in with the silver. If you plan on processing large amounts of plated silver, then be aware that to process 300 kgs of standard silver plated items(0,2 weight % of silver), it takes about 8 hours @ 50amps. Temperature does not matter much, only take care to not go above 60 or 70 deg. celsius - when hot, sulphuric acid will attack copper. Removal of silver plating from scrap copper busbar. May 20, 2009. Hi, folks. letter 7022 describes an electrochemical stripping method. letter 43265 describes a melting method and a chemical method. letter 25979 offers some operational parameters.. Please remember that the internet is a one-room schoolhouse with post doctorate chemical engineers and 3rd-grade schoolchildren reading the same pages.
