Cementation with copper

[Yggdrasil]

Tested all samples with stannous which I also purchased. All my results are posted in REDNECK. None presented strong dark purple, but many presented faint purple that then apparently dissolved back into solution and went clear again. Had 1 sample that turned into dark orange egg yoke, but then also went clear after adding more stannous. I was able to capture maybe a thimble of brown good from SMB methods across all samples. However, when treating waste with copper and processing as i describe above I collected probably 3 more thimbles of brown goo... so now am going to melt this brown goo over the weekend and see what comes of it. The copper cementing produced far more precipitate than the SMB. My best guess is that the gold around here is ultra-micro-scopic (mind you i have it under micro scope, but even then they present as pin heads hard to see clearly... but many of them... probably need to go from 50x to 500x or 1000x to get a visual). Anyway.. to your question... Yes I did.

The Stannous you have presented so far has been dubious at best.
And the last you did is dissolved Copper and some Copper I Chloride, that is what I think anyway.
If there had been PGMs in solution the Copper pipe would have been flash plated in less than a second or so.
So I'm expecting the results of your tests.
What tests are they going to do?

So I just found these photos and apparently forgot that it did start reacting pretty quickly and I initially was stirring but then just let it sit to see how it went and seemed to come out it stages. First the black then the light gray then orange and now since the bottom half of the copper broke off a bit of copper. It’s been awesome to see!!

Mine did not bubble that much at all, if any that i can recall. It just started turning black, and in seconds. Probably completely coated black/gray inside 5 min... with small flakes and black "dust" coming off around an hour later. All in all it was probably 50% black/gray goo dust, 25% small black flakes, and then 25% large black flakes that came off when I took the copper bar out and sprayed stream of water from hand held water bottle on it with a bit of forces. The copper under it was an off color pink/orange that appeared to me to be another coating of something... but when put back into waste it darkened up again. Very odd to me... probably radon, or something exotic. I'll post whatever it is this weekend after smelting.

I think you meant to direct that to Eshane. My results were as close to flash as you can get I think.... but don't now if that was missed gold or PMG. My stanus tests within the REDNECK posts were dubious, yes... and I don't know how to interpret a test that presents very light purple and then goes clear again. I am thinking the gold is so small the acid redissolves it and it goes back to clear ?.....

Sorry about that, your avatar color is about the same, and your methods and "Ore" as well so I did not realize you have come into this discussion.
Nothing exotic at all, fresh copper is pinkish in color, and Ra is a noble gas reacting to nothing at all.
The only thing it does is emit radiation when it decays into Polonium, Lead and/or Bismuth

Hello again hope all is well! I put a small suspected ore sample in cold aqua regia and after giving it some time to soak filtered out a small sample of the liquid. I then placed a small piece of copper pipe into the filtered liquid. I became a bit discouraged when I didn't see anything happening but knowing copper is lower on the reactivity scale I allowed it time and after about a week I noticed the copper pipe started to turn black, then after about another week I noticed a light gray forming over the black, about a month into the experiment I saw this

The submerged half of the copper broke off and has been laying at the bottom the other half is in the above picture

My ore plates out fully within a day or two... It's black and sticks hard onto the copper. It's the only way I'm able to get the precious metals out of my ores. No other way has worked so far, that's because I suspect 1. the solutions are too dirty 2. There are compounds in the ore that prevent precipitation via smb/ferrous sulphate. or 3. Im an idiot. I assume the traditional methods smb/ferrous will work after PM's are cemented out. I dont have a furnace hot enough to smelt the ores first, so this is my only option for now.

After the PMs are out, there is nothing to precipitate.
