Gold's reaction with alluminium

[shryansh22]

Hey so I am gonna start up a refinery I just wanna know if gold can be mixed with silver and alluminium to make 99.5% gold. And can gold be seperated with the help of gold reagent from a blob made of gold, silver, iridium, ruthenium cadmium

Gold alloys poorly with Aluminum.
It alloys well with Silver.
What do you consider as Gold reagent?
In my opinion, by asking these questions you reveal that you are not ready to start a refinery.
I hope you have somebody with expertise and knowledge along with you.

Thanks for the reply!.So what metals according to you will mix well with gold other then silver.

Also yes I have someone who'll be doing it for me. I just don't wanna be a dummy infront of em

Many, among them Copper, PGMs, Zinc, Tin, Lead and so on.
It all depends on what you are trying to accomplish at that instance.

So what do you mean with Gold reagent?

 

[Martijn]

Aluminum is alloyed with gold to make purple gold and the alloy is brittle.

From:
https://www.bullionbypost.co.uk/ind...opper, nickel, iron,the colour of gold alloys.

"Gold Coloured Alloy
Zinc, copper, nickel, iron, cadmium, aluminium, silver, platinum and palladium are all common metals alloyed with gold.

Gold and copper are the only two coloured pure metals. Gold is yellow and copper is a reddish brown. All other metals are white or grey in colour but have various effects on the colour of gold alloys. A gold coloured alloy for jewellery will typically be one of three colours; yellow, white, or rose."

It would help if you can explain in full what you are going to be processing and what you aim to do after refining as in why you want to alloy refined gold with silver and aluminium.

 

[Yggdrasil]

I am well aware of that, but in refining setting it do not make much sense.
And you do not mix it with refined Gold to make it 995 refining wise.
As this would mean to have 999+ and mix in tiny amounts of Silver or Aluminum or both, this will be alloying not refining.
Anyway it will be at 80 ish percent Gold and not what he is talking about.
I think.....

I think there are some language barriers here, and he has not even replied to what he means with Gold reagent.

Find the metal reactivity chart posted a couple of days ago in another thread about Copper spots on Gold coins less then .900 fine.

So what do you mean with Gold reagent?

Gold reagent settles the gold down when we dissolve it in the acid removing the unwanted particles other than gold
Also zinc , tin , lead ,copper,silver are the metals I already know but we need some other metals as well for eg- aluminium , but problem with aluminium is its not gonna dissolve with gold properly without changing its colour
We are experimenting some shit with gold alloys

So what you call reagent is actually a precipitant!
It will be much easier to give advice if you learn the correct "chemical language"
Many different substances can be used:
SMB, Ascorbic acid: Oxcalic acid Iron Sulfate and so on.

What is your starting material and how do you dissolve it?

So why do you want to add elements to the Gold?
Usually refining is the opposite, removing other metals from the Gold so it becomes pure.

In his defense:
"In an aqueous solution, precipitation is the "sedimentation of a solid material (a precipitate) from a liquid solution". The solid formed is called the precipitate. In case of an inorganic chemical reaction leading to precipitation, the chemical reagent causing the solid to form is called the precipitant."
source: https://en.wikipedia.org/wiki/Preci... precipitation,form is called the precipitant.

and:
"In chemistry, a reagent (/riˈeɪdʒənt/ ree-AY-jənt) or analytical reagent is a substance or compound added to a system to cause a chemical reaction, or test if one occurs."
source:
https://en.wikipedia.org/wiki/Preci... precipitation,form is called the precipitant.

So they are both correct, that said, he could have made the context clearer in his post. There are many reagents for many purposes.

To answer his question: separation from a "blob" (alloy) will not be very efficient with hydrometallurgy, in smelting there could be some like adding or purging a chloride through the melt bath to separate silver as silver chloride.

At least, as far as my hobbyist chemistry knowledge is correct.

Do you mean dissolve(dissolving in chemical acids) or alloy(melt with other metals)?
Separation in wet chemistry means dissolving one thing and filtering the dissolved elements from the solid ones by filtering, then selectively precipitating the gold from the other dissolved elements., leaving you again with a precipitated solid and a solute, to easily separate by filtering.

"Gold reagent" is "often" used for the test acids and also by noobs when talking abot the so called green concoctions for refining.
I just tried to get a response I could advice on, without going too deep into the matter.

I agree, and it's very unclear (to me) what his goals are. we'll keep on phishing.

 

[shryansh22]

With dissolve i meant without leaving any physical changes or traces in the gold like colour and melting properties
Reasons for my question- 1)Basically I am trying to test gold's maleabililty and its properties when mixed with other metals which do not leave any physical traces
2)I am trying to test my XRF machine's capabilities that what all metals does that detect with gold .
So if any suggestions, plz let me know

Ok.
As long as the alloy is homogenous the XRF should be correct.
Regarding alloying, I do not think many elements will be visible in the quantities you describe.
The mechanical properties may be a different story.

 

[FrugalRefiner]

Aluminum is one of the light elements some XRF machines can have problems with. I'll be interested in your results.
