Try Carolina biological In Burlington iircAfter tonight's run its obvious I'm getting a little of the plating under the gold, nickle, maybe silver... I'll test it later for silver.
Anybody have a local source for nitric acid 66ish% ? Not thrilled about paying a $20 hazmat fee on top of the cost plus shopping.
0.2% would be 35.11 grams of gold (1.23oz)
0.3% would be 52.67 grams of gold (1.85oz)
0.4% would be 70.22 grams of gold (2.47oz)

@Alfred What metal am I contaminated with to produce the green color?
Do you not expect to strip some copper from your basket?
You keeping a running tab on costs for this, I’m curious.
I've never actually done the process myself but my knee jerk reaction would be copper.
The next batch I process will get a better wash with hot HCI then HNO3 to help remove impurities prior to dissolving.
Try a hardware store ? Last box I bought was to make liquid ant killer.If I can ever find borax again

Nitric acid came in today. Cleaned up the precipitate from the rinse water with a nitric wash and aqua Regia. Ended up with 1.4 grams. The gold that makes its way into the rinse water is a fraction of what's in the cell. I've deplated 10lbs of the 38.5. I'm excited.

He pulled the 1.4g from the water he used to rinse things during the process, he needs to get working on the real stuff to figure out what the yield will be, but he’s having too much fun with the transformer and warm acid bath.I'm confused, 10# of material got you 1.4 grams? What did I miss?

my sense is that you’re gonna make minimum wage on this project, but that’s better than most hobbies.
Where do those pins come from?

Sit down.
I bought them from an acquaintance...
.... As brass scrap....
... For $40 ($1/lb).
I was looking to buy scrap brass for an unrelated project, he pulls out this bucket. Knew they were plated but "by his reckoning" there was only a few grams and not cost effective to reclain.
I might be tempted to extract a bit of the gray separately from the black and process it. If it’s lead wouldn’t it be cheaper and faster to get rid of it now than to let it settle and have to remove it chemically?
honestly I never thought I’d get into this process, but it’s interesting.
