I just joined the forum about a week ago, and I am wondering what would be the best way to process the ruthenium and silver form the SMD resistors.
I have come up with a process and if I should modify anything to improve my yield.
1. Ruthenium contains Ag solder, so I will dissolve the solder in concentrated nitric acid to make silver nitrate (AgNO3). Then, I will use heavy gauge Cu wire to precipitate the silver onto the wire, then I will purify the powder with borax while melting.
2. Then I will crush the resistors and dissolve the powder into HCl, then precipitate the Ru with ammonium chloride.
Is there anything I missed? If so, comments would be appreciated. Note, I am still collecting the resistors, so I would like to ensure that the process will go smoothly. Thanks!
