Okay, so we're finishing up the first part of my first AP type process. Like many new people, I made some mistakes, learned some things, you live and learn though right?
Okay. So probably the first issue I encountered (which I didn't expect to be an issue until about an hour ago) was that apparently I shouldn't be mixing types of material, because thats exactly what I did and for reasons Ill list later it became an issue.
So. My process was using a mix of Peroxide 3%, distilled vinegar 5%, sea salt, and fresh air from a low speed pump to agitate.
Within 30 minutes I noticed the clear solution becoming blue. At 24 hours, I saw my first gold fleck, aaaah the excitement.
I waited about 75 hours. The similar processed video I'd watched on youtube was 90 hours. I got impatient, and should definitely have waited.
In my mix was some seemingly gold plated pins, a pinless CPU, memory fingers, sim cards, bits of circuit board which had gold foil looking areas.
What came out was a mess. Now, I am still filtering some of the solution as of the time of this post, but-
the sim cards are NOT stripped, not even slightly.
the memory fingers are mostly stripped, and probably would have given me many more foils had I waited the other 15 hours?
the Cpu was pads are unscathed.
the gold foil boards are fully stripped, but seemed much thinner than the gold in the memory. most of this memory passes through the kitchen sieve. running the same material through a coffee filter makes a blue buildup with flecks in it, but I can't seem to recover them in any easy way.
I think this particular process would work great if only using gold finger material but the other stuff makes it hard to sort and spray the other foils loose.
Pics related.
From here, I plan to consume the foils in another solution that the youtuber posted, and precipitate the gold using ascorbic acid.
One thing I am curious- what is the turquoise color caused by? Is this silver from the solder? Copper? If either of them, what can be used to drop these metals from the solution after filtering the gold foils?
