My goal is to precipitate gold out of leached ore. Small, just to prove the concept to myself.
Cell: 1pt. canning jar, carbon cathode, s.s. anode.
Leach: NCl / Chlorox
My first run was just to get everything working. I used a battery charger, set on 12v.@ 2amps. Too much current for a such a small container. Ended up dissolving the anode.
Second run. Used a bigger anode. Ran a light bulb in series (+) to cut down current. 100% better.
The "ore" I was using was just some unknown sample I found laying around the shop, probably little gold.
I leached the ore overnight or so, filtered and put in the cell.
Ran it around an hour. Observed black precip. on the bottom of the cell and on the anode.
Dried the precip. Unfortunately for me I ran out of reagent to test it, so I'm at a dead end there.
But what I did notice is that the anode was etching away, I'm pretty sure that was the black powder.
I think the next run I will bring th Ph. up to 4 or 5 before I turn it on. My thinking is it would be a little more gentle on the anode.
Am I headed down the right road here? I realize that "raw ore" is a bunch different than plated fingers and such, but mabey not so much.
