Precious metal refining calculator?

[Neogroup]

Has anyone ever created a precious metal calculator that can give you chemical proportions based on the amount of gold that you're refining and it's carrot at the time of processing. In other words something that you can use to calculate a very closely the amount of nitric acid, hydrochloric acid sodium metabisulfate Etc?

Welcome to us.
Your question can not be answered as no batch of scrap/ore/waste is the same.
That is why we rely on assays or assessing on the fly what is needed.

Her is some links that may allow you to do these assessments yourself:
Hokes book, safety and waste treatment are more or less mandatory.

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: https://goldrefiningforum.com/phpBB3/viewtopic.php?f=54&t=19798
2. Then read the safety section of the forum: https://goldrefiningforum.com/forums/safety.47/
3. And then read about "Dealing with waste" in the forum: https://goldrefiningforum.com/threads/dealing-with-waste.10539/

Here is something I've learned..for the most part, it has yielded the same results. Five pound of unshielded ram cards will give you 1 pound of trimmed gold fingers. After processing the foils, I usually get no less than 3 grams, no more than 5 grams of gold. Depending on the process and the ram cards.

1 pound of fingers from 5 pounds of ram?

I found that a bit much, can't be very close cut, I think.

www.chembuddy.com for calculators....EBAS is very good but you need a good understanding of chemistry. Used it for years to approximate reactions.

I cut them just below the gold foils. I know I have a few ram cards left...I will weigh them just to be certain. Seems like 25-30 desk top ram cards weigh a pound. I will repost my findings.

I stand corrected..I looked in a post that I replied to back in 2022...it's 10 lbs of ram cards instead of 5 pounds. My apologies

The poundage can not just be said like that. There are lots of variations of cards. Like it take 13 LBs of server ram for 1 pound of gold fingers.

Im incorrect...approximately 10lbs of ram cards....my apologies for the incorrect statement. Also depending on the cards. I've had some ram cards and the " gold teeth" were nearly worn off. Anyhow.....be safe

This thread has gone towards e-scrap and for e-scrap I think it is impossible to create a chart. He does mention the word carrot [sic]. This leads me to believe he is talking about jewelry scrap. I have produced the attached spreadsheet for refiners who do stone removal in beakers to tell them the quantity of acid for the digestion. While stone removal lots are not melted first, the chart also applies to shot from melted karat gold as well. It does not break down by karat because as a general rule it takes 1 liter of aqua regia to dissolve 7.5 ounces of metal. This uses a 4:1 Hydrochloric Acid to nitric ratio for use in a beaker with a watch glass cover.

I just noticed this guy posted on June 1 and hasn't been back. I should look for that stuff. Anyway this may help others

Rereading his post I still assume now as I did then.
It might be a typo for carat.
