Hey everyone,
I have a bunch of silver salts from laboratory waste which consists of insoluble silver halides, oxides and metallic silver. I would like to purify
it and obtain silver ingots, preferably with as little wasted silver as possible.
What do you suggest I do? The problem is that I do not know the exact composition of the waste.

You can boil the salts with NaOH to convert everything to silver oxide, then filter, wash and re-suspend. Now you can reduce the silver with dextrose
or sucrose to the metal.
