HCL & Bubbler V Aqua Regia Question

[Yggdrasil]

Thanks, so electroplating is Metallic Gold not Gold Hydroxide.
All the plated materials in solution have had the gold plating removed by AP.
So, now i research whether the sands dislodged could be metallic gold plating, not gold hydroxide.
And without acid, not using stannous until I read enough to make a chemistry based call on what the sands could be.

Thanks
MM

I have once again moved your new mess together with your old mess.
KEEP ALL POSTS REGARDING THIS BATCH TOGETHER please.

Will do.

quick one...
I wanted to check these sands without acid.
I am staying away from chemicals until I trace my steps on the solution (and its contents).

my study of the four chlorides of Gold, tells me I have no gold chloride OR chloroauric acid. This is just based on the chemistry, on how you can arrive at these two chlorides.
I now understand that electro plating is undertaken by metallic gold and not gold hydroxide.. So I may have eliminated other possibility.

Would smelting a gram of (powders pictured) give me any indication?

First This one is a bit off.

Actually you use a Gold salt and then plate that to the electrode by electricity and thus making it metallic again.

Next, maybe but it all depends on how much Gold id in your powders and what else is in there.
If this is from the same batch, there could be around 0.1gram in there, at least not more.

Now would be a good time for pictures as you work.

Put a half gram or so of the powders in a very small glass container, a beaker would be nice. Add just enough hydrochloric to cover the powders. Did the powders dissolve? Did the acid change colors? Stannous test a drop. What did it show? Pictures please.

If any powder remains, slowly add bleach to your hydrochloric acid. A little is all you need. Remember that bleach neutralizes acid. Any powders left now? Did the solution change color? Stannous test a drop now. What did it show? Pictures please.

If you cannot get hydrochloric I do not know what to expect from acetic acid, but the results should be close to the same. Wait until some the more chemistry knowledgeable members can explain before trying it.

Gold Salt= Aucl3 right?, so when treated with an electrical charge creates metallic gold from the Aucl3.


0.1grams beats 0.0 grams and can also become 0.2 grams.

How are your studies going?

Salt is an ionic compound between a metal and non metal.
NaCl NaOH Na₂O₂ and so on.
Gold salts are AuCl, AuCl₃, AuCN and H₃AuO₃ and more Gold salts.

These when in an electrolyte will act as a transfer media between a Gold Anode
and the Cathode and plate that Gold onto it in metallic form.

Hi

This is the material(photo),
I have no HCL (weekend)
Could this have similar results?
Acetic acid (cleaning vinegar) and hydrogen peroxide solution? maybe on the bubbler for 15 minutes?

Stop with the vinegar.
Wait until you find some HCl/Muriatic acid, should be accessible in most hardware shops.

Did you read my post to the end???

There is also no need for more chemical mixup/messes until we know where your gold is. With out stannous chloride we are just guessing and that could take forever. In my opinion, vinegar is for pickling foods and is not for refining. Let’s find out first if any thing of value exists, then we can figure out how to get it recovered.

This level of ignorance and not responding to questions is getting quite annoying to be honest.
You can write a long reply, giving detailled info, advice and ask questions and he just jumps to something totally new.
And I'll probably get a like from him for this post without any question answered.
I'm out. You can't save them all.

Hey Mart, I'm reading your posts thoroughly.

HCL on its own has dissolved 1.5 grams into solution, no bleach used.

Nice Golden solution (photos0, I have around 12-15 grams of powders left & stored.
And possibly around 5 grams in old solutions.

Once again thanks for your advice...it is being taken, maybe my responses are not coordinated.

What do think?

I use AR occasionally to dissolve stubborn gold plated parts that don't want to easily dissolve in AP, but only if it's just copper/gold. Other things are cable flexes to which they GLUED gold foil, and has no copper behind it.
