Hi all
I collected more than 1 lb of MLCC's of different size coming from various boards.
Now I wanted to apply the method described by gold-n-scrap on a small sample of 10 g. I terminated the first step for remove the base metals, let the solution cool and settle over night. I poured off the purple solution. And now, that's the point why I'm asking: The method of scrap-n-gold says to syphon again leaving only the solids in the flask.
Now I'm insecure because I yes see solids (shiny metal) in the beaker but also a gray sludge. Does it come from the tin so that I can throw it away or what else could it be?
Thanks for any hint.
