Why not using a high purity gold cathode. Less Titanium contamination. Or even using a gold bowl, needs maybe 1kg of Gold, depending the size. Doesn't have to look pretty, just thight and stable. Casting or asking your goldsmith friends👍🏻

Absolutely BRILLIANT work, S! Great nodularisation, makes for easier peeling from the titanium I'd bet. I think you should move to this method. Even with inquarted gold, I'd bet you could get higher purity yields with Ag/Cu byproducts to be collected at the bottom of the beaker. Suggestions/Ideas: 1. A titanium sleeve to hug the inside circumference of the beaker [slight spring tension] with the anode bar suspended in the centre. 2. A silicone lid to fit the beaker to reflux the HCl [prevent loss through evaporation. 3. Perhaps an Arduino to control heating to maintain the 140F temperature. Thanks for the great electroforming content! Greetings to you n family from Hopkinsville, Ky! [Yes, I thought "shark tooth" as well, lol.]
All good suggestions. Especially titanium sleeve with anode in the center. I believe that the excessive distance between anode and cathode in my experiment slowed the process considerably.
As the gold atoms leave the anode bar they "etch" out the crystalline structure that actually makes up the bar. This allows the light to difuse all over the place and show you the structure you cannot see otherwise. Yes, that structure is always there but your eyes fool you because the surface is usually smooth and the light has no bevels to reflect off of. I do love physics. I bet that tooth looks amazing under good magnification. Another winner, Sr. I'm thinking Mrs. Sreetips probably took possession ASAP.
I don't think u want the stirring on while running this cell. You can entrain the contaminate particles in the gold sponge. Since the contaminated particles are staying suspended.
Yes, and the physical motion might slightly inhibit the rate of plating as well. I'd love to see an empirical comparison of the yield rate with stirring vs no stirring.
The book is a little dated. It says you can use a fan by the window to handle the fumes but thus just won’t due. Also says to flush the drain with plenty of water to protect the pipes.
Thanks Sreetips, love this channel !! Oh boy, those days of stripping zinc off cathodes by hand when the edge strips had fallen off and the zinc grown all around the edges. stripping 7 and a half tonnes a day. I'm talking 30 plus years ago lol. Was even worse when we stripped copper off cathodes where the edge strips had fallen off, did not tear so easily, copper was plated onto titanium cathodes as well, we would only make about 100 tonnes of copper a week.
Question about free hydrochloric acid and the evaporation issue. (I'm guessing distilled water was used in that solution.) How critical is that 10% free hydrochloric acid? Does it get "used up" in the reaction? Would that have been water evaporating and not the acid? Also, something else random: the stock pot has been having certain issues. Maybe consider starting a new one next time instead of adding your leftovers from the last one. Dry out your left overs and keep it stashed somewhere to mess with on a later date. Thanks for sharing your play time with us ;)
I would love to watch a video recorded micro-shot of that anode bar during the charged/transfer process. Very curious if one could visibly observe and discern the molecular lattice structure breakdown and dissolution.
Thank you. Love your videos. I really like how you would take jewelers carpet, or the clay polish wheel and extract gold from them. As you prepare your video agenda, perhaps you could find more ways to extract gold from unusual places or objects. No matter what, i'm hooked.
It would be intersting to wheit the final product. See if the wheit outside the electrolyte is s'il the same. Thank you. I love the electro deposit of gold. And i stil would love to see 14 and 18k gold refining with this setup
The anode must be fairly high purity to begin with. But I may inquart some karat gold, part with nitric, then melt the recovered inquarted gold into an anode (should be about 990 parts per thousand). Then use that as the anode in the gold cell.
Some observstions and comments if allowed: 1) The cell has a charge parity. For every Au-ion that leaves the Anode into the electrolyte an Au-ion attaches to the cathode by aquiring electrons out of the electrolyt in absolute the same moment. The question of the distance between the electrodes is inferior as long the conductivity (aka concentration of electrolyte = 1/ resistance) and the Amps and Volts are high. 2) I would not use the stir-bar. Any impurities get agitated in the electrolyte and like an old rug, the gold sponge at the cathode catches those and the growing gold crystals enclose them in the sponge. By not agitating zhe fluid the impurities just sedimenting down under the anode an stay there. One more reason to evaluate the gold cell similar to the silver cell. I even think its not necessary to heat the cell as long as you got time on your side as with the silver.
If you want to grow nice fairly big crystals, I recommend to reduce the surface area of the cathode to a pretty small size, maybe half a square inch. As optimum I suggest a high purity gold cathode in irregular shape to give the cathode some prefered accumulating points. I think nice and fairly big gold crystals would sell pretty well on your ebay
Most of the gold comes from the 10 ounce anode bar as it dissolves from the current flow. But some of the gold from the 90.2g in the electrolyte will get deposited on the cathode. The gold in the electrolyte becomes slowly depleted as the cell operates.
@@sreetips I'm curious about that. Theoretically (in my mind) it should be a one-for-one molecular exchange and no depletion of the solution should occur. Your yield recovery mass of the chloroauric should be exactly what you dissolved into it initially - hopefully we will see in Part 3.
The gold in the electrolyte, and the gold coming off the anode are identical. The cathode can’t discriminate which is which. So invariably, some of the gold from the solution will get deposited as the cell operates. Sort of like collateral damage. I’d guess that about 20 grams of gold on that cathode came from the electrolyte.
@@sreetips But in theory at least every electron coming off the anode knocks loose one atom of gold into solution, while one atom of gold is plated onto the cathode from solution. I don't doubt that there are losses but I would expect them to be negligible, in the sub-gram range. Very interested to see what you recover when you precipitate out the solution, and how the final mass balances between the anode, cathode, and solution.
This is fascinating! It’s amazing to watch metal react with various frequencies of electricity. It’s almost symbiotic to watch. One element reacting with another, it’s awesome!

When you purify the bar by electrolysis you have to collect the impurities that were in that bar somewhere; do they end up in the gold chloride electrolyte or did they fall off the cathode and get picked up by the stirred solution and end up on the rough surface of the gold? When you purify the silver nitrate you have a filter between the electrolyte and the anode.
This is awesome stuff, I have a question? What happens to the gold that’s in solution? I see the anode dissolves and gold is deposited on the titanium cathode, but is the dissolved gold just making the connection between the anode and cathode or is there more to it?
The sole purpose of the electrolyte is to enable the gold ions to travel from the anode to the cathode. But some of the gold from the electrolyte does get deposited as sort of collateral damage.
do you have to run the stir bar? i se a potential problem. impurities is suppose to fall off and end up on the bottom of the beaker. now it is sendt around and can get caught in the growing gold crystals.
In order for electrolytic refining to be successful the anode material must be relatively high purity to begin with. Otherwise the electrolyte becomes fouled very quickly.
Thank you Sreetips. Gold is so captivating. I almost cannot wait to see some of that in bar form. Ok now your going to think I’m weirdo. lol I don’t think gold happened by accident. Well possibly a long, long ,long time ago it did. But I think gold has value all across the universe. Not necessarily monetary value either.
Gold became money by default. Nobody voted or got together and said let’s make gold and silver money. It just happened thousands of years ago. And it’s still money today, that hasn’t changed. Just think of it this way: long after Amazon, Apple, bitcoin, and the dollar are gone and forgotten, gold and silver will still be here. And they will still be valuable
Three nines is industry standard for pure gold. The extra nine is totally unnecessary unless needed for some specific purpose such as a standard test comparison.
When you test for the presence of gold using stannus chloride. Doesn’t it take some of the gold from the solution your testing. If so do you save the strips to recover the gold later? Could you tell us what you do with the strips?
when are going to do the jump into getting your official Sreetips Hallmark , is there a American school or would you have to go to England to get one ?
That would be awesome. Only problem is; somebody would find a way to counterfeit it. My best shot at authenticity is to publish a video of the gold. The pour lines and features on each piece is like a finger print that can’t be duplicated.
Try like a silver cell, you can use gold (shark tooth) left over from the experiment, add rings, gold bracelets to your basket. I think gold goes to the titanium plate, silver and other metals will remain in the basket, Try it, you have nothing to lose, it's an experiment, I'm curious how much metals are lost through smoke, it's worth a smoke recovery experiment and turn it into liquid, from liquid to extract precious metals
Two problems: the anode material must be fairly high purity to begin with or else the cell would quickly become fouled with base metals. And a stainless bowl cathode would react with the gold chloride electrolyte. This method, anode and cathode facing each other, is the most efficient way to do this.
Metals have a crystalline structure, and I assume gold is no different. Cooling it quickly produces smaller crystals, and doing it slowly would produce larger. Would love a close-up of the surface.
Imagine a zillion invisible gnomes, each of which has a spoon that can pick exactly one atom of gold off the bar and send it into the solution. And that's what all 1 zillion of them doing, over and over again at random, repeating the "scoop an atom from a random spot" operation at a rate that boggles the mind. Since it's random, there's no telling (other than the generalization "it'll be one that's directly in contact with the electrolyte") where the next atom might be grabbed from. As more and more atoms get grabbed from random places, it will eventually average out to "everyplace has been hit" if run long enough, but while it's running, there's no telling what the surface texture is at any given moment, but it's *HIGHLY* unlikely that "smooth" (which is required for "shiny") would be an accurate description. Presto - There's your textured surface. To have it be smooth would require atoms to be plucked out in an orderly fashion to preserve the smoothness.
Hi Sreetips, just a quick question regarding cementation of silver from waste solutions. If there is any gold still in solution will it cement out with the silver and what is the best way to make sure other than the stannus test.
Yes, boiling nitric will put a little gold in solution. But it’s usually just a trace and not worth trying to recover. If there’s gold in solution with silver then I just cement it out on copper with the silver. Melt the cement silver (with the small amount of gold in it) and run it through my silver cell. In the cell, the gold will get trapped in the anode filter because it’s insoluble. Then I recover the gold when I process the anode filters for the precious metals that they contain.
Are you doing this to practice the procedure? Whats the benefit of refining 999 to 99999 that you can’t do with a few more chemical refinings? How pure does the anode have to be, is there a lower limit? Thanks!
There is no real value benefit difference between 12k gold scrap and 4-5 nines fine. He has stated this many time. The book did say however, the anode had to be "fine gold" and that is defined as .999 pure. The book also said that you should use impure gold for the cathode. sree used platinum. The anode should be near pure gold because it just gets eaten up. Using impure gold would also just get eaten up, although impure gold would also add resistance to the power flow at some point, and possibly contaminate the electrolyte, negating the purpose of an electrolytic cell.
@@sreetips I love all your videos and content, please don't think I'm knocking anything...It's just in my nature to know why things work and reasoning so I can understand better
Three nines is industry standard for pure gold. So the fourth nine is totally unnecessary unless needed for some specific purpose such as a test standard. The only reason I did it is for the show. To demonstrate that I can, and produce a new and interesting video for my channel.
Sreetips -- I have a question. When there is a loss of gold after processing, what accounts for the loss of gold? Evaporation (mollucules in vapor)? Splashes of gold in solution? Gold left behind in paper filters? Fine gold disolved in waste solution poured off? I think in a recent video you had like 7 grams of gold missing after processing (I might be wrong, I can't remember exactly). Do you know where / how the gold is being lost?
All the above. There are losses along the way. Minimizing them will depend on the skill and technique use by the refiner. Also, l probably made an error when sorting the karat scrap. Threw in a piece that was plated or gold filled by mistake. That can throw the yield off
@@sreetips Ahh I see. If it was an actual processing loss, rather than just a sorting mistake, then you are likely to recover it later on from the gold refining waste liquids and/or your saved paper filters. Thank you for taking the time to reply to my question. I love all your videos!

Thank you Sreetips. Gold is so captivating. I almost cannot wait to see some of that in bar form. Ok now your going to think I’m weirdo. lol I don’t think gold happened by accident. Well possibly a long, long ,long time ago it did. But I think gold has value all across the universe. Not necessarily monetary value either.
Gold became money by default. Nobody voted or got together and said let’s make gold and silver money. It just happened thousands of years ago. And it’s still money today, that hasn’t changed. Just think of it this way: long after Amazon, Apple, bitcoin, and the dollar are gone and forgotten, gold and silver will still be here. And they will still be valuable
@@sreetips I’ve never heard something so true. lol
Maybe I'm just stupid but is the difference between 3 nines fine and 4 nines really worth all this?
Not when selling it to a refiner, but it is when making a video about it and selling to fans.
He said that he's just doing it for the show I believe
Three nines is industry standard for pure gold. The extra nine is totally unnecessary unless needed for some specific purpose such as a standard test comparison.
I look forward to part 3. Is it really four 9s fine?
Yes!
Love the explanation!
When you test for the presence of gold using stannus chloride. Doesn’t it take some of the gold from the solution your testing. If so do you save the strips to recover the gold later? Could you tell us what you do with the strips?
I toss em
when are going to do the jump into getting your official Sreetips Hallmark , is there a American school or would you have to go to England to get one ?
That would be awesome. Only problem is; somebody would find a way to counterfeit it. My best shot at authenticity is to publish a video of the gold. The pour lines and features on each piece is like a finger print that can’t be duplicated.
Maybe you could make a video converting US coin junk silver to pure. Or how about a gold krugerand that is mixed with copper, to pure.
Try like a silver cell, you can use gold (shark tooth) left over from the experiment, add rings, gold bracelets to your basket. I think gold goes to the titanium plate, silver and other metals will remain in the basket, Try it, you have nothing to lose, it's an experiment, I'm curious how much metals are lost through smoke, it's worth a smoke recovery experiment and turn it into liquid, from liquid to extract precious metals
I'm thinking, by this method you refine gold without using a lot of acid.
Two problems: the anode material must be fairly high purity to begin with or else the cell would quickly become fouled with base metals. And a stainless bowl cathode would react with the gold chloride electrolyte. This method, anode and cathode facing each other, is the most efficient way to do this.
This was so neat thanks for letting us come along 🫡
Hi. Where do you sell your stones? On eBay??? Love the videos. Amazing stuff.
I have in the past.
Thought if you had another Gold Cathode you quite possible could have recovered more huh cause that last one desolved quite Quickly huh!!..
I think a closer distance between anode and cathode would speed it up.
Great video! Why does the shark's tooth have a texture. Why not a perfect smooth surface?
Metals have a crystalline structure, and I assume gold is no different. Cooling it quickly produces smaller crystals, and doing it slowly would produce larger.
Would love a close-up of the surface.
Imagine a zillion invisible gnomes, each of which has a spoon that can pick exactly one atom of gold off the bar and send it into the solution. And that's what all 1 zillion of them doing, over and over again at random, repeating the "scoop an atom from a random spot" operation at a rate that boggles the mind. Since it's random, there's no telling (other than the generalization "it'll be one that's directly in contact with the electrolyte") where the next atom might be grabbed from. As more and more atoms get grabbed from random places, it will eventually average out to "everyplace has been hit" if run long enough, but while it's running, there's no telling what the surface texture is at any given moment, but it's *HIGHLY* unlikely that "smooth" (which is required for "shiny") would be an accurate description. Presto - There's your textured surface. To have it be smooth would require atoms to be plucked out in an orderly fashion to preserve the smoothness.
@@Ferd414 Oh,.... you mean turbulence. Interesting theory.
I’ll try using a small microscope on it in part three.
Hi Sreetips, just a quick question regarding cementation of silver from waste solutions. If there is any gold still in solution will it cement out with the silver and what is the best way to make sure other than the stannus test.
Yes, boiling nitric will put a little gold in solution. But it’s usually just a trace and not worth trying to recover. If there’s gold in solution with silver then I just cement it out on copper with the silver. Melt the cement silver (with the small amount of gold in it) and run it through my silver cell. In the cell, the gold will get trapped in the anode filter because it’s insoluble. Then I recover the gold when I process the anode filters for the precious metals that they contain.
What is your TH-cam channel?
sreetips
Are you doing this to practice the procedure? Whats the benefit of refining 999 to 99999 that you can’t do with a few more chemical refinings? How pure does the anode have to be, is there a lower limit? Thanks!
There is no real value benefit difference between 12k gold scrap and 4-5 nines fine. He has stated this many time. The book did say however, the anode had to be "fine gold" and that is defined as .999 pure. The book also said that you should use impure gold for the cathode. sree used platinum.
The anode should be near pure gold because it just gets eaten up. Using impure gold would also just get eaten up, although impure gold would also add resistance to the power flow at some point, and possibly contaminate the electrolyte, negating the purpose of an electrolytic cell.
@@En-Pea-Sea Small correction, sreetips used titanium for the cathode.
@@apveening oh yes, you are correct, he did say titanium. Thanks.
@@En-Pea-Sea You're welcome.
@@En-Pea-Seano benefit then why do it?
Is it really worth all this work to get 9999 fine gold ? I love it and never miss a video but seems high risk low reward...
Cheers
Absolutely!
@@sreetips I love all your videos and content, please don't think I'm knocking anything...It's just in my nature to know why things work and reasoning so I can understand better
Three nines is industry standard for pure gold. So the fourth nine is totally unnecessary unless needed for some specific purpose such as a test standard. The only reason I did it is for the show. To demonstrate that I can, and produce a new and interesting video for my channel.
@@sreetips Amazing...I don't think there's anything you can't do brother..
Still waiting for you to auction off that smock lol
Sreetips -- I have a question. When there is a loss of gold after processing, what accounts for the loss of gold? Evaporation (mollucules in vapor)? Splashes of gold in solution? Gold left behind in paper filters? Fine gold disolved in waste solution poured off? I think in a recent video you had like 7 grams of gold missing after processing (I might be wrong, I can't remember exactly). Do you know where / how the gold is being lost?
All the above. There are losses along the way. Minimizing them will depend on the skill and technique use by the refiner. Also, l probably made an error when sorting the karat scrap. Threw in a piece that was plated or gold filled by mistake. That can throw the yield off
@@sreetips Ahh I see. If it was an actual processing loss, rather than just a sorting mistake, then you are likely to recover it later on from the gold refining waste liquids and/or your saved paper filters. Thank you for taking the time to reply to my question. I love all your videos!
Compared to how you already purify gold, will this method make it pure, and by how much?
Should be four nines
Gooooood evening from central Florida! Hope everyone has a great night!
Goooood evening!
Hello my good friend. First on clip,so bedtime 🙂
God bless you🌺
thank you for the video
Awesome video
Looking forward to part 3.
We still need to get Sreetips and SlowMo Guys together to slowmo the gold coming out of solution. Let’s make it happen.
I don’t think it would be very satisfying. SloMo is best for real high speed stuff like bullets.
Nice work. Very impressive. But, I prefer it when the gas generator is used to take the gold out of solution.
I like it too
I would rather watch your videos I learn more that way
Can you write book ISBN?
There is no ISBN, it's too old. Original print was 1940.
Why do this at all if the anode is pure gold and the gold on the cathode will be pure what’s the point. Or is it degrees of purity?
Three nines is industry standard for pure gold. So the fourth nine is totally unnecessary unless needed for some specific purpose such as a test standard. The only reason I did it is for the show. To demonstrate that I can, and produce a new and interesting video for my channel.
Got it and it’s all great content I love watching. I was only trying to clarify. Keep up the great work.
The first thing I thought was Sharks tooth, then second what did you do with it lol
I love electrolysis I part powered one of my deisel Landrovers using a wind turbine and water electrolised hydrogen oxygen gas but it eats the stainless cathode really fast so I have to find something it won't munch away, before I can start using it again.
This is definitely alchemy at its best, thanks for the download too thats worth a lot more than its weight in electrons
Thanks for sharing
I made a necklace from the sharks tooth.
@@sreetips ah good call
There’s a video posted about how I made it posted on my channel.
@@sreetips oh cool I'll look that one up
what is the solution
Chloroauric acid for the electrolyte.
Sir do you have like any drip tray or collection tray in the fume hood in case any precious liquid accidentally spills,?
No
