Demonstrating silver recovery from weakly-magnetic MLCCs

Some people toss the MLCCs that are somewhat magnetic. DON'T DO THAT! Some of them have SERIOUS value in them! In this and the follow-up video, I show that both silver and palladium are present in a small sample of weakly-magnetic MLCCs. First I dissolved the base metals with HCl, washed the solids twice with hot distilled water to remove all traces of chlorine, then added a little dilute nitric until all visible metal had dissolved. I let the 'dust' settle out (mostly titanium oxide from the MLCC ceramic), and drew out some aliquots of the clear solution for testing. Behold the results!
