Hei everybody ....I sure love my new hobby( Scrap refining.) :shock:
I need some advice on what is best, I have been looking around this forum and elsewhere on how to refine my ceramic cpus.
From what I can see it would be a waste of time to use AR for different reasons.
1 Concentrated nitric acid is hard to obtain
2 Concentrated nitric acid is very dangerous(compared say to chlorine or HCL)
3 Concentrated nitric acid can be expencive in some parts of the world.
=====================================================================
What I want to aim for is getting rid of the base metals first. I want to work on this, base metals have got to go first before refining anything.
I want to be clear on nitric acid, low concentration nitric acid is what I want.
Something that I can handle without worry or better put with less worry.
Something that I can make from nitrate salts, very easy to make (save money)
I'm talking about low concentrated nitric acid, 10% to 20% . You need to dilute your nitric acid anyway to make a nitric bath for the ceramic cpus to get that base metal out of the way before refining it with HCL + BLEACH
Step 1 Nitric Bath
Step 2 HCL+BLEACH
Then the other steps, getting the powder, melting it and so on.
So is this the way to go, seems to me like aqua regia is a waste o time and that on this very forum people are in contradiction. Because using AR means that all the base metals will disolve into the solution with gold and you will have base metals with gold into solution, when precipitating the gold will other elements not precipitate with it ? So extra steps would have to be taken like refine again and again, repeat steps, sounds like a waste of time if you can get rid of the base metals at first then know you can refine with ease because all you have in solution is gold.
I understand that AP is not good for ceramic cpus, then some people come and say that a nitric bath is not good either, then some people come and say that AR is not the way first and you must first get rid of the base metals.
What is the way to go. 1 or 2 ?
1 Get rid of the base metals first.
2 Refine everything with AR or poor man's AR
IS 10% Nitric Acid enough to disolve the base metals in time. I understand that over 60% nitric acid needs to be disolved with water (50% water, 50% Nitric Acid)
I would go even low to 5% nitric acid if it's possible, less danger better for me. Those redish brown fumes are sure ugly :shock: I don't care if it takes longer, I got the time.
Also very important, how not to make your gold dissapear into the diluted nitric bath for leaching and become invisible, once that happens there is no way to filter the gold with the mesh. After the Nitric leach bath I would have to filter the gold to catch it into the filter while everything else gets discharged. So what everyone wants is gold foils that float into the low Nitric Acid Bath.
This thread is only on Ceramic CPU.
My key questions.
1 -What is better. Get rid of the base metals first or refine everything with AR.
2 - If nitric acid bath is best for ceramic cpu and is the way to go then how much Nitric Acid should be use per total, the nitric acid is going to mix with the water and form a lower concentration anyway, per total is 20% nitric acid enough(after mixed with water to form the diluted substance). How not to go too high in prencentage with nitric acid and risk disolving the gold foils into the leach solution, or how not to go too low and not dissolve anything at all.
Thanks, I await your response.
