I don't know if this would be intetesting for anyone else, but I would love it if you demonstrated the weight of the combined liquid (without gold in solution) and solution with disolved gold. I know it is a moot situation but I feel it would be a neat comparison. Chemistry is cool! Science rules. And you are the youtube King of alchemy ❣
Had the same thought but different concept. Gold bubble vs conventional bubble. Can I do it and will in it fall faster? Can I recover the gold with a method I made? Basically a bubble reactor. Essentially an air drying process. We will see.
I’ve done this experiment. I weighed the gold solution and the same volume of plain water in the same container. I did it in the video with “Wohlwill” in the title.
@@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.
Wow! Great vid. Different dissolving, different precipitations……like a greatest hits compilation. Been going back through your previous stuff and this particular one really stands out. Thanks for putting in all the work!
Wow seeing the different densities of the liquids after the first filter was really cool. The gold solution is always really interesting as it gets so concentrated too. That red color is incredible.
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 ;)
Absolutely awesome sreetips!!! That powder is so clean looking. And that bar is screaming look at my stunning beauty! You have the refining and pours mastered there sir. Thank you for taking us along on your adventure!
I find dropping the gold slowly in big batches helps stop that from happening. The indicator it was dropped too fast is the gold crystals forming on the beaker.

Wow, I never realized there was so much chemistry involved in purifying gold. I thought it had a lot more to do with different temperature cycles. Cool!
I’m still a really big fan of the oxalic reduction process and sponge the most. This was a really interesting way to show the differences in methods and especially wastes products. Awesome video sreetips
Could you do a video on all that gold waste to see how much went over? Or do a refining of all the waste(the waste buckets) that would be pretty cool to see.
Thank you very much for the video. I learned a lot. one of the best video I have seen lately. I hope in the next few video you could maybe show us how to grow gold crystals like you do with silver. again thank you very much.
Thanks again for sharing your life an knowledge with us. Grateful to learn so much! I really did enjoy seeing 2 different was of precipitating the gold out... I still find the SMB fun to watch an less rinsing. But not equally interesting to observe... Thanks Mr. Tips
I wonder if putting a bit of graphite between the melt dish and the thermal wool would keep them from sticking to each other. Worth a shot. Awesome video, as per usual.
At 13:28 on 1 side of the thin dissolving bat you can see the mint press marks. On side 2 you can still see the con centric rings from when it was poured and cooled.
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. But what you did (HCl then more SMB) works just as good. The general rule for high-purity precipitation is to go slow -- like overnight.
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?
I think it's really important to mix the solution with a stir bar during the smb dropp. It might also help to reduce the concentration of the solution by adding distilled water, it raises the PH of the solution and gold should stay out of it.
@@niagarajoe4402 Considering the amount of gold, that was not enough water at all. I'm talking about 5-10x more water. There might be hidden buffer effects that stop the PH from rising. The stir bar is necessary because there might be hidden pockets of acid in the mountain of gold.
@@dingo23451 You are right. Diluting it further lowers the acidity. When working with such a big batch, it is probably a good idea to measure the PH and bring it up to a neutral state with distilled H2O.
i was amazed when you melted the powder, i thought you will dry it up to show the powder gold, then wet up the powder and melted up the wet powder into a refined gold. good job.. ,
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).
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)
A very good video again.......You try to keep us all interested with different things, a placer gold one would be nice again, maybe speak with Dan Hurd.
Got the jealousy bone worked up after watching this one Senior Chief, LOL. I just processed 2 and a half grams today and had to fight to get it, but was worth it. Great video as always! Have learned a lot from your videos, so I hope you keep them coming. Also, have you ever tried dissolving the SMB in water prior to using it for precipitation? Always wondered if it would be a benefit for large batches like this.
Super cool to see you refine 16,000 dollars worth of gold! Maybe it would be more efficient to do a bunch of small batches to ultra high purity, and then melt together.
Hi Stree. I found your channel a couple of months ago and I’m hooked. This is the science class I wish I had. Question that I haven’t been able to figure out. Why take silver to create the silver cell? Does it produce more silver than were you started or is it just a purification? Or something else. The silver cell is beautiful with the blue liquid. I’m still working my way thru your catalog but I’m learning so much along the way. Thanks ✌️💛
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.
You should also dissolve the SMB in distilled water and add that as a liquid to drop the gold out of solution. If your chloroauric acid is plenty watered down, then the gold will drop out of solution more efficiently, and you’ll lose less gold to gold waste.
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...
wow, dealing with thousands of dollars like that takes skill and courage!! make yourself a tea with the left over powder:)) now that would be an experiment:)
I'm not a chemist, or have done any refining, but would adding a stir bar during the smb precipitation make the gold stay out of solution better. It seems that maybe the acids are hiding in the powder/sponge.
I might be wrong here but it's just a thought on your gold going back in solution. I'm wondering if you did still have a lil nitric left and when you were doing your rinses with hydrochloric it rehydrated the solution and it started dissolving some gold again. Just a thought.
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.
Man it gives me indigestion to watch all that gold go in and out of this mortal realm like that! lol. I think ill try a silver cell first. This is a great channel, I gotta find that book now.
I have a question. May have been answered at some point. I see the scratches in the glass as that gold precipitates. How long do you get from each beaker/flask/container before they need to be retired? Can you tell when they are ready to be removed from service?
Your 24 carat gold powder making technology is very nice I am very impressed with you I like your nature remember please happy good afternoon namaste ji
I've just been assuming that the ice cubes were distilled water ice.. I've thought "I'll make that with distilled, maybe DI water" probably a dozen times.. nice to hear you confirm it.. I would like to know more about the chemistry .. things like, what compounds are created in the stannous test?.. but I can find that on Google..
Have you ever done a video showing how you recover gold from those temporary waste containers? That would be super interesting I think. Always curious just how much gold you’re actually pouring off in those things.
This is great,! some chemish ha!, i used to see my father and brother dissolving gold, and also white gold to use it for plating jewelry, and it defend what is the grade,18k , 14 k plating. combination of silver, copper and gold. but for white glod i dont know what combination they used. they used hydrocluric and muriatic acid and netric to dissolved the metal. Then they used 12vdc and the jewelry and soak it in the solution when they are plating. He also get back some of the silver that stick on the copper rod the he leave inside the tube with the solution, he then collect those sludge that stick on the rod and put then in the bolw wiith water and heating it up. these combination of sulfuric acid and water that he used to submerged the jewelry that he heat to cool down by soaking it. then heat up the slimey sludges sulotion until it turned into silver but in chunk not powder. the gold he dont do it because is a long process and he give to his friend that know how to acquired back the gold, ... one time by brother in law his putting the milk powder into the container and heating it up until all liquid is evaporated by evapuration, he think i dont know what he is doing, I told him that your collecting the gold and he just smile and be quite... great job for turning the gold into powder..
Great video! In case anyone was wondering why not just use h2o2 to start to avoid nitric acid all together is that hcl and peroxide works best with gold foils or powder but is not very effective for bars - ask me how I know :)))))
Okay, I'll bite.... How do you know? I've been a little curious about that myself because it seems like it would be cheaper and much less potentially harmful waste produced. I have a personal thing for efficiency and optimization and my father says I'm lazy so I have to constantly point out to him that there's a fine line between laziness and efficiency. Suffice it to say I prefer efficiency expert over lazy but I suppose that's kind of splitting hairs unnecessarily
Always quite fascinating to see the different ways these precious metals get dissolved and turned back into solid

Working on the video right now.
Put a clock in your fume hood so we can see the time fly
Good suggestion
You should also dissolve the SMB in distilled water and add that as a liquid to drop the gold out of solution. If your chloroauric acid is plenty watered down, then the gold will drop out of solution more efficiently, and you’ll lose less gold to gold waste.

I would like to know more about the chemistry .. things like, what compounds are created in the stannous test?.. but I can find that on Google..
I’ve used distilled water in the past. Today I use tap water. Not sure of the stannous compounds.
Have you ever done a video showing how you recover gold from those temporary waste containers? That would be super interesting I think. Always curious just how much gold you’re actually pouring off in those things.
Search “waste container” in the search block on my channel. I think I did one last May.
Is that strange-looking dirt (gold powder) trying to form faceted Crystaline matrix? it's hard to tell on this old Galaxy S7 I'm watching on
This is great,! some chemish ha!, i used to see my father and brother dissolving gold, and also white gold to use it for plating jewelry, and it defend what is the grade,18k , 14 k plating. combination of silver, copper and gold. but for white glod i dont know what combination they used. they used hydrocluric and muriatic acid and netric to dissolved the metal. Then they used 12vdc and the jewelry and soak it in the solution when they are plating. He also get back some of the silver that stick on the copper rod the he leave inside the tube with the solution, he then collect those sludge that stick on the rod and put then in the bolw wiith water and heating it up. these combination of sulfuric acid and water that he used to submerged the jewelry that he heat to cool down by soaking it. then heat up the slimey sludges sulotion until it turned into silver but in chunk not powder. the gold he dont do it because is a long process and he give to his friend that know how to acquired back the gold, ... one time by brother in law his putting the milk powder into the container and heating it up until all liquid is evaporated by evapuration, he think i dont know what he is doing, I told him that your collecting the gold and he just smile and be quite... great job for turning the gold into powder..
Great video! In case anyone was wondering why not just use h2o2 to start to avoid nitric acid all together is that hcl and peroxide works best with gold foils or powder but is not very effective for bars - ask me how I know :)))))
Okay, I'll bite....
How do you know?
I've been a little curious about that myself because it seems like it would be cheaper and much less potentially harmful waste produced.
I have a personal thing for efficiency and optimization and my father says I'm lazy so I have to constantly point out to him that there's a fine line between laziness and efficiency.
Suffice it to say I prefer efficiency expert over lazy but I suppose that's kind of splitting hairs unnecessarily
