I'm refining some e-waste, and I decided to do a boil in 50/50 nitric & distilled water to start things off.
This left me with a viscous red/brown sludge... The solution definitely has copper, silver, and lead - and not all of the pins are dissolving despite adding a good bit of nitric.
The sludge is too viscous to filter off with my setup (we're talking one drip per 30 seconds, and I have a liter of sludge)
So I decided to do a warm AR bath with everything. My thought is that I will hopefully be able to filter it more easily, then take whatever crashes out with SMB and do another nitric bath for my precipitate + any remaining solids from my original slurry, and then proceed from there with another AR step.
Does that sound like it will work?
I'm honestly regretting this one as I don't expect to get more than a gram or 1.5 max... but I feel like I'm in too deep to stop lol.
Thanks!
