I have monovalent gold in my soil
which dissolves in hydrochloric acid
I don't know how to extract it
Please advise

1. How do you know you have Gold in your "Soil"?
2. No Gold metal dissolves in HCl

I did not say the three-sided gold
I know gold disolve in aquaregia.
I mentioned monovalent gold ( one-sided gold) that dissolves in hydrochloric acid
You should drop the Youtube videos.
There are no Gold that dissolves in HCl.
Gold salts yes, Gold metal no.
Gold metal has a valence of 0.
Gold Chloride (AuCl) has a valence of 1 but that is a Chloride of Gold and as such a salt,
AuCl it is produced by decomposing Au(III)Cl (AuCl3).
It is highly unstable and do not exist naturally.
There have been several dubious attempts during the time claiming the existence of exotic species of Gold that can not be detected.
They have all been debunked.
So I ask again:
How do you know you have Gold in your soil.
Since you claim it, you should have some tests that it is there.
Or at least that you have Gold in solution by testing with Stannous Chloride.

I meant monovalent gold Au(|)
After I dissolved the soil in hydrochloric acid and heated it, the color of the soil changed, that is, all the elements of the soil entered the solution.
And another question is, why did the soil turn green? Is it copper? The color of the soil before I heated it in hydrochloric acid was violet-purple

Yes . I tested it with stanous choloride

Please stop mixing unknown soils in acid.
Chemistry works in an entirely different manner to that which you seem to think.
See if you have a reasonable analytical laboratory close to you and pay them for a basic metallic screening.
Cost you a cupule of hundred quid but will stop you suffering from cancer or other poisoning by handling unknown metallic salts improperly.
Once you know what you have, we can advise you on the most effective method of recovery.
Until then, you are just playing with some potently very noxious compounds you do not understand and can not explain to others.

I am sure that I have gold in my soil. I did different tests and got different sediments. Let me send the picture.
I am not afraid of the risks of this work because I have financial debt

Can you show us the result?
And your soil before and after?
I suspect what you refer to as soil is something else.
In English soil is the part of the ground where you grow your crops.
https://en.wikipedia.org/wiki/Soil
Nothing here looks like Gold.
If there is any Precious Metals in there you can put in a piece of Copper and they will cement out.
Just make sure it is acidic

Correction. You what and need there to be gold in your soil.
This never helps with clear and unpolluted thinking.
Unfortunately, the likelihood of you having found a financially beneficial deposit every one else has missed over the last two thousand years is startlingly slim.
If you have gold, it will be in such small amount that nothing short of the proper testing methods will detect it.
You have three main choices.
(A) invest in someone else's help. This will have the benefit of an impartial observer finding the answer quickly.
(B) set aside several years of study to learn how to test your self. This will be time-consuming and cost much more than the test for one sample. But result in a tradable skill even if you find your sample to contain no substantial value.
(C) Mess around with dangerous chemicals in no particular order, trying to reinvent seven thousand years of human ingenuity and development through trial and error.
If you are already in a fiscally uncertain situation, I can see the allure of such an enterprise, but must warn you of the folly you seem to be following, Path "C".

The color of the soil is purple in nature
After it was dissolved in hydrochloric acid, the color of iron turned green

Hum.
Since they have yet to invent an XRF scanner that can focus back in time to a different part of the planet based on a photograph.
I do not understand what you think anyone outside quite a brilliant geologist could tell from your photos?
Maybe you should be consulting a Geology group before a gold refining forum.
Have you tried grinding and panning it before playing with acids?

First and foremost get some gloves on your fingers.
Dissolved known salts are not good for you, and even more so unknown ones.
Next get someone to identify that rock it clearly have some minerals in it.
The bottle caps are that your Stannous tests?
If so they are not likely to be positive.
Use a cotton bud or a piece of white paper and drip one drop solution then one drop of Stannous.
This will be much clearer.
Instead of any back and forth discussion as to whether or not this is gold maybe we should discuss your soil. Gold typically isn't in everyday backyard soils, so if you have gold in your soil the area where you live must have some unique geological features to put it there. Is your property on an ancient river bed? Is gold ever found near where you live? Is there a history of gold being found in your region? And last is your property possibly near a runoff from an old industrial discharge which may have discarded it's waste nearby?
Maybe figuring out if there is a reason for gold to be there should be preceded by all of the conjecture about recovery. If it is truly gold and it is in recoverable quantities, we have enough brain trust here at the forum to advise you properly to recover it safely.

From time to time we get members here claiming to find gold in the most unlikely of places. It would be interesting to hear from members about naturally occurring gold that has been discovered in the most unlikely of places. @Deano comes to mind when thinking of recoverable gold in the ground and he may be able to give examples of gold discovered where conventional wisdom would think it wouldn't be found.
I have seen many places where gold can be identified by multiple methods after physical separation from soil but cannot be identified by fire assay or acid digest without first undergoing the physical separation.
This physical separation is incredibly difficult to carry out as you are looking to separate gold particles sized at single digit microns from a soil sample with particle sizes from single digit microns to millimetres.
Note that one micron is one thousandth of a millimetre, it takes a really good microscope to even see particles of this size.
Neither I nor any of the many people I know with an interest in such gold have ever come up with a commercial method of recovery to this sized gold, just doing the separation for identification purposes is incredibly difficult and laborious.
The areas where I have seen this ultra fine gold particles are always either known gold areas or are regarded as likely hosts for such deposits.
The grade of this gold is low and non-commercial for the most part even if separation could be done at commercial scale.

Well this an opinion I respect from Deano from down under. No stranger to gold in it's natural form.
Many times in my career I have been sent samples of ore that were not assayable by standard methods, either qualitatively or quantitatively. Yet the owner was convinced there was payable gold in the ore. None of them ever would own up to how they determined that this mystery material contained gold.
Best we can tell you from what you have told us is to screen the soil through a 5 micron screen with the hope the fine monovalent gold passes through the screen with some of the fines in the soil. This sample, having passed the screen may be separable by density in a gold pan enough to give you a sample to test further.
Still open to answers from other regions of the world about gold found in unlikely places.
One of the issues here is that he have no assay what so ever and have not tried to get one as far as I remember.
He "knows" and needs ther to be Gold but have no relevant research besides Youtube to refer to.
Since you guys are more versed into the finer understanding in chemistry than me.
Any element in a valence state other than 0 is some kind of Salt is it not?
So a Gold atom in a valence state of 1 is a Gold atom that has been deprived of one electron?

Iran is noted to have Carlin-type deposits of gold in the North-East. The disseminated nature of the deposits make extraction difficult and only profitable for very large deposits and by large commercial mining companies. Hopefully, this will help.
