Hi everyone I recently. Purchased some scrap that I got for a really good price. Everything was in a pretty large fire so a lot of the boards are burned down to foils. Problem is that when i use acid peroxide to de etch I get a whole bunch of bits of burned silicone flakes and other junk making any recovered pms incredibly dirty nearly impossible to filter properly. My question is what is the best way to pre process this stuff so j can get the pms separated to properly put into solution. Also what is the quality of scrap I bought it all appears to be telecom grade from 70s 80s and some newer network boards. It seems very good I can shred most boards down to foil by hand. Though most of the foil if not all appears to be just copper though some look like the gold in the ic chips melted out onto the foil behind . Thanks
