@@spokehedz yes atoms are atoms and gold atoms are far more dense than any of the other atoms that you're going to encounter in this process, mainly, oxygen, hydrogen, chlorine, nitrogen, sulphur, copper, silver and small amounts of various other elements. Not that these atoms aren't generally found in elemental form in solution but rather as ions and complex molecules. So yes, the gold bearing solution will be significantly heavier than the same solution minus the gold.

Precipitations are a tricky thing, because if it happens too fast, inclutions can be formed. There are a few ways to mitigate this... - reduce the concentration - increase the temperature (the resulting crystals tend to "rearrange" in the forming process to give more uniform / less irregular shapes) - slow down the feedrate (gives the mixture time to reach equilibriium) - use seed-crystals as a starting point to form the bulk (aka pieces of condensed matter) My suggestions for the SMB reduction step: dissolve and filter your SMB (maybe hot saturate), do the precipitation at around 50-60° C (sorry, I'm metric ;) ), use a magnetic stirrer and add the SMB solution first slow - then faster with your separatory contraption... this should give you a more uniform product and controlled reaction. For the reduction with the iron salt... a magnetic stirrer and elevated temperature should do. Maybe adding a 1/10 of the reduction solution first (to produce seed-crystals) and after a couple of minutes the rest... For washing the precipitated gold.... 2 mL of your hydrochloric acid in 1 L of distilled water should be enough to keep all the iron and other salts in solution, as the pH of this solution is less than 1 pH. This should save you some hydrochloric acid in the future ;)

Strange Things: Yes, you had some nitrates "hiding" in he gold precipitate, (co-precipitated). You could avoid it by adding the SMB slowly to a more dilute gold solution.

The two different densities of liquid is so cool! I wonder if the 'hidden extra gold' when you work in large amounts is "big chunks" of gold (compared with what they are when they are dissolved, they would be huge), that due to the high overall concentration of gold in solution. Because, how else would it be able to make it through the filter?

Have you considered trying the Wohlwill process again to electrolytically refine a larger amount of gold? That ought to allow you to skip the repeated acid-based refining steps, since the gold anode only needs to be 95% pure. Then again, it would require keeping a large amount of chloroauric acid on hand to serve as the electrolyte. The last time you tried it, you used a 24k gold cathode, but stainless steel can apparently also be used toward that end. I wonder what the difference is, since if they work equally well, why would anyone use an expensive gold cathode? I recall that the Royal Canadian Mint refines all their gold electrolytically using stainless steel cathodes. They also seem to avoid acid entirely by refining the doré bars they buy from mines to 95% purity by pumping chlorine gas through the molten metal during assay (a.k.a. the Miller process).
@enamelbucket2081

i always wondered what it would look like to make a somewhat large electrolytic gold cell, albeit its cost i think it would be a viable way to refine large ammounts of gold if you already have the materials on hand. plus the gold would be extremly pure and crystaline too probably (which would probably make them more expensive)

The electrolyte is made of silver nitrate about 150g of high purity silver dissolved in a liter of liquid. It’s a purification as the impure silver shot dissolves in the anode filter, passes through the electrolyte and plates out as high purity silver on the inside of the cathode stainless bowl. No silver is created out of thin air. It’s only what you put in is what you get out.

When you heat liquids and dissolve into them, it creates a "super saturated" solution which when cools down might have an impact on your refining.. or precipitating.. I am sure there are ratios for gold/vs nitric acid, but it would be great video creating your own ratio table. See how much nitric is required for 1g, 10g, 100g for records. Could also experiment with how much hydrochloric acid is necessary to "carry" the dissolved gold and whether more or less distilled water is better... Using gold to consume the excess nitric is brilliant circumvention...

@djcbanks
2 жыл бұрын
That was most likely the case. It can get trapped in between the gold precipitate very easily and even though he swirled it around when rinsing, most of the gold stays together keeping it trapped because it’s so heavy. If he would have used a glass rod to stir the gold precipitate while rinsing it, he could have gotten it rinsed more thoroughly and prevented some of if not all of the partial redissolution of the gold. It takes more than you would think to rinse all the gold to perfection. That’s one of the keys to having a pure product when your done, making sure you rinse, rinse and rinse again. And after your done rinsing, rinse some more.
