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

If there are any PGMs there the will plate out in no time. And such pacify the surface if the copper.
That is why cementing PGMs needs aggressive stirring.
And you will know in seconds if it is there.
Have you had your ore assayed now?
 
Looks more like dirty copper carbonate than a cemented precious metal.
Please define ore. Rock or metal?
He has beeing on and on with this ore he is convinced to have PGMs in it, but so far he has not managed to show us an assay.
 
I would opt for Cu(I)Chloride as well. Makes sense since you left that Copper for (too) long in that beaker. Cu(I)Chloride is hard to get rid of. Sometimes a bit of HCl helps. It is not supposed to, but I noticed that it will dissolve the Cu(I)Cl. You could dissolve the solid remains one more time and filter the liquid hoping that the PMs will separate from the Cu(I)Cl. If I am not mistaken the Cu(I) Chloride forms once all the Oxygen has been used up in that solution. That can happen if you leave the Copper in it for too long. Anyone?

My REDNECK plating was nearly immediate, you could watch the copper turn black in seconds. Some flaked off, some created a plating. I did have to stir every day or so just to removed some of the black cement. I then washed the precipitate in water 4-5 times.. then in half nitric (35%) and half water 3 times. I now have a brown goo. However some of the larger cement flakes which did not dissolve in the nitric have a silver gray look to them. Going into furnace this weekend. They represent all copper cemented precipitates I collected during the waste disposal process of the REDNECK ore sampling rampage I went on some time ago. I am still at it, but moved from a couple mason jars per week, down to test tube size sampling and processing. I'll probably have enough chemicals to last for 20 years tinkering around in test tubes... fun.

The nitric washes did turn blue the first two times.. the third remained clear, with only the slightest tinge of blue hue. Assuming that was some copper that precipitated while cementing on the copper bar I purchased to process my waste and capture anything of value the SMB didn't catch. I have also moved to precipitating with cupperous / FeSo4 or something like that. It was sold as a gold precipitating agent.. pretty cheap. Appears to have worked in the test tube, worked better than SMB on same ore type anyway.

Did you test with Stannous?
 
I'm curious how small your ore sample was if that half liter of solution is a small sample from that small ore test with AR.

So a bit more clarity would help.

And for your own sake, please wear gloves when handling chemistry.

A miracle has occurred and someone has finally agreed to help me get some testing done on a few different samples!! They were received a little over a month ago and being that this person had I’m sure an already pretty busy life before my request for help not sure on exact timeline but I’m just so beyond thankful for there time and kindness!! It would be incredible to finally be able to sell this unbelievable material and finally get my motorhome and really start helping some people!! Since apparently money is needed to do that

So you can finally present some tests here?
A Stannous test would have been enough to show that you have something of interest.

I didn’t get a weight for some reason but probably weighed close to a Troy oz

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!!

That looks like partially crushed rock with larger pieces in it.
What do you think is in it?
These are some examples of the starting material I often try different lighting to capture it’s true beauty.

I’m suspecting a mix of platinum group metals, copper, galena, gold, iron, +\-. I’ve been trying to get that question answered for about 2 1/2 years hence my backyard lab using extreme cautions as these procedures can be deadly

So far you have not presented anything to support your claims.
Not a good Stannous test not anything else.
But soon we will know if you present your results when they arrive.
 
Thank you great read!! Could I just add some more of my starting liquid?
Did you read it?
That is a document showing how the Copper Chloride etch aka AP works.
Why in the world would you want to add more of that to a solution of alleged PGM salts?
It is not Copper metal anymore and can not cement anything in that state.
 
Did you test with Stannous?
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 goo 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.
