Inquarting is to bring the Gold to 25% so the Nitric can access all the Silver.Hey,
I’m wondering if it’s possible to skip the step of inquartation even if you know there is over 25% silver in your gold and instead just use more nitric to remove the silver ?

My apologies, I meant to say if the content is say;Inquarting is to bring the Gold to 25% so the Nitric can access all the Silver.
Thanks mate! Already reading through Hokes book for the second time.Welcome to us by the way.
Her is for your studies:
We ask our new members to do 3 things.
1. Read C.M. Hokes book on refining jewelers scrap, it gives an easy introduction to the most important chemistry regarding refining.
It is free here on the forum: Screen Readable Copy of Hoke's Book
2. Then read the safety section of the forum: Safety
3. And then read about "Dealing with waste" in the forum: Dealing with Waste
Suggested reading: The Library

You must inquart. Now the gold "protects" the silver and noting would happend. As Yggdrasil say, the gold must down to 25 % for the nitric to work.My apologies, I meant to say if the content is say;
Au 80%
Ag 17%
Other base metals 3%.
Would it be worth inquarting or would you just use nitric then AR?
Too much Gold to be able to reach other than the outer layers of Silver and base metals.My apologies, I meant to say if the content is say;
Au 80%

I have no recommendations regarding furnaces.I have two further questions if you wouldn’t mind answering.
I’m going to go with the inquarting route.
In Hokes book she says to use silver to inquart instead of copper due to not being able to pull that copper back out of solution when finished.
Are there any other benefits to using silver>copper ?
I ask because I have a large amount of gold I’m wanting to refine (roughly 500g) and I feel like destroying 1.5kg of my silver bullion bars/coins would cost me more ( due to loss of premium/resale ) than it would just buying 1.5kg of copper and losing that.
My second question is in regard to furnaces. I’m leaning toward a propane furnace ( VEVOR VEVOR 12KG Propane Smelting Furnace Kit Melting Furnace Double Burners 2700℉ | VEVOR AU ) to melt the gold/copper alloy together.
Would there be any reason to go with an electric furnace ? They seem to be way more expensive with a smaller crucible size.
Many thanks!
The thinness of the metal goes only to ability to dissolve, not to the fineness of the end product.Say you had a mechanical set of rolls, which could squish the Au to a very thin layer. How thin would the say 90% Au, 10% Ag have to be rolled to, to achieve a 3-9's refine?
Meant to add , after rolling to micron thin, then placing thin , rolled sheet in Nitric. What would be the required thickness of the rolled sheet of 90/10 alloy, to achieve 3-9's Gold, without in quarting?The thinness of the metal goes only to ability to dissolve, not to the fineness of the end product.
That is entirely dependable of your process after dissolving.
I think you still need to refine it after, there will always be pockets and grains not accessible.Meant to add , after rolling to micron thin, then placing thin , rolled sheet in Nitric.

It will depend on your Silver source first, then the alloy of the Au material. Silver nitrate is a liquid, so don't know if you mean some solids filtered out, or if the liquid component is 100% Ag nitrate.I have inquarted my gold with silver, melted, poured into shot, boiled in water/nitric (3:1) and filtered off the solution.
The nitric solution turn a lovely shade of green or blue ( you can see the shade in the filter paper ) which I then filtered and noticed these reflective crystals on the paper and in the solution. I chilled the solution and more crystals appeared.
Is this solid silver nitrate ?
Silver source was 9999 Perth mint coins. Au alloy was about 80% Au, rest of the alloy was Ag, Cu, Fe.It will depend on your Silver source first, then the alloy of the Au material. Silver nitrate is a liquid, so don't know if you mean some solids filtered out, or if the liquid component is 100% Ag nitrate.
It is a solid but it is very soluble in waterIt will depend on your Silver source first, then the alloy of the Au material. Silver nitrate is a liquid, so don't know if you mean some solids filtered out, or if the liquid component is 100% Ag nitrate.
Is there a way to test if it’s silver chloride or silver nitrate ?It is a solid but it is very soluble in water
