Gray dust with foils

[dark_yami1]

I put alot of phones in some Acid Peroxide and a some foils. Yet i have a problem there is some "gray dust" in it. I'm trying to get the dust out. Some small transitors and other crap got caught in it. Any suggestions? This was my first attempt.

Search the forum for my posts on copper I chloride.

It's soluble in HCl. The other garbage should have been removed before processing, but will stay behind once the foils are dissolved and filtered none the less.
