[@azdrifter51]

what was cool was watching the stir bar increase in speed when you added water, showing just how dense the solution was with devolved gold

[@Miketz]

Thanks so much for this video, I have assumed it was possible but had not come across anybody actually doing it. Just a couple of pointers for the electrical side of things that you seem to be a little unsure of: The only absolute value is the current. This will dictate the speed of the reaction, which will determine the properties of the deposition. If all you are after is pure gold to be melted, go fast and go hard. If you are wanting a specific result, (such as a smooth coating) then slow and steady at a lower current will give you what you need. However, there are variables: The surface area of the electrodes, their separation distance, the conductivity and temperature of the electrolyte and the supply voltage is adjusted to accommodate for these variables to deliver the desired current. I believe your current was about right for your setup, any higher and the temperature of your electrolyte would have increased too much. To get the hundreds of amps of the original process, you'd need a much larger volume of solution to keep it from boiling.

[@Enjoymentboy]

This reminds me of a school trip to the royal canadian mint when I was young. They used this same process essentially with the only real difference being they used titanium cathodes. That part always stuck with me because when I was a kid titanium was this magical super metal that only nasa and the military used. But good for you sir. You are purifying gold to the same high level of the RCM!!!

[@bobedwards8896]

titanium still my fav material

[@matthewmichaels1046]

I love your channel. I have watched many of your videos. I always wondered if the gold solution weighed more and I've always wondered if you could make a gold cell. Great video.. one day I will do what you do and you've brought me that much closer. Thank you

[@sreetips]

Thank you!

[@gregkretchmer3588]

As I understand the process, you can do this with most metals, you just need the electrolyte to contain a salt of the metal your after. You could use mixed copper metal, for a lower cost experiment, say a nickel coin, which is mostly copper with copper sulfate as the electrolyte with a bit of sulfuric acid added, any contaminates will turn into a slime on the bottom of the beaker, in this case, the nickel metal. Your gold experiment did not have enough contaminates to show up as slim and the electrolyte is still loaded with gold, but it is fully reusable and I'd say this was an excellent video. Try it with 14 k gold and notice the silver on the bottom. Or, you could use a silver salt electrolyte and end up with gold on the bottom. As a note, some metals are ok to deal with as metal, but as salts, they are very toxic, like nickel.

[@Rob337_aka_CancelProof]

Now you got me sitting here staring it my gold ring on one hand in my titanium ring on the other thinking I don't need these all that badly I guess I could sacrifice them to the god of learning with little regret

[@johnh8615]

Been waiting so long for you to do this. Wow . Do a slow experiment in gold crystal. Anode and cathode in solution, in gold electrolyte. And power it with two dissimilar metals in electrolyte( the lowest volts and amps) for a year. Bam. Then out pops the most beautiful slow gold crystal ever. Just like the Tucson gem show. A masterpiece to sell for a master dollar.

[@sreetips]

I made a note of your comment for future reference. Sounds interesting.

[@georgemclean825]

Another great video sir! I was engrossed from start to finish and thoroughly enjoyed it.

[@CrimFerret]

I suspect the gold was coming out of solution as crystals since you saturated it while boiling. Recrystallization is a common method for purifying a compound dissolved in a solvent. That's probably some pretty pure gold. It might even be more pure than what you'd get by using sodium metabisulfate. You could put some of the electrolyte in the fridge or even freezer (don't actually freeze it) to get more. It might be interesting to see how pure it tests out doing it that way.

[@wadehampton1534]

Wonderful experiment, sreetips! And I subscribed to Dr. Young's channel too! I'm an amateur watch servicer/repairer, and I sometimes re-plate watch cases and bracelets with gold or nickel. We set up a similar electrolytic cell for the plating process.

[@Kenneth_H_Olsen]

Canadian royal mint used Titanium cathode and gold anode in the same acid bath . In the video he just scraped the gold off the titanium plate . And could be used again . A surprising low voltage and a surprising large ampere . Great work man . I'm a subscriber . The Egyptians and incas did the EXACT same thing . In caves using plant juices . Did i say caves ? I mean megaithic stone constructions . Secret chambers . High science

[@gregschaust4298]

Absolutely awesome. I am happy that it worked. My thought as to why they used a higher current power supply in the book was to increase the speed of the process. If you are planning on doing this in the future, you could always melt the high purity gold and reform it for another use in the cell.

[@speedonz]

They were probably using a larger anode.

[@buggsy5]

The operative value is current density. In the book, the cathode area was vastly larger, so a higher total current is necessary to obtain the desired current density. To keep the current density relatively constant, they use multiple anodes and cathodes. Another factor that affects the current density is the spacing between the anodes and cathodes.

[@jennyferfarias971]

Can you tell me what is the name of the book?

[@buggsy5]

If you taper the anode, so it is thinner and narrower as you progress towards the bottom, you should minimize or even eliminate any of the anode falling off.

[@arnedalbakk6315]

Hello Mrs and Mr sreetips. This is only not refining, but truly a masterpice. Like you say sir.. A pice of art. In my eyes.... So close to 1000. So clean gold... Thank you🌹

That’s incredible how well that worked. Those crystals are really cool looking. Awesome video as usual Sreetips 👍

[@samw5767]

Enjoyable production values and professional working environment in all of your youtubes. Also, remarkably steady hands in pouring out solutions of pregnant liquor (envy here)... The 'Wohlwill' video above: very instructive. Obviously, you could scale it up by running several of your beaker electrolytic at a time cells in parallel. Some authorities say it's possible to get .99999 purity this way; although this might be two x through the Wohlwill process. Three suggestions for Wohlwill (and not to go against Hoke, but to tweak her just a bit): 1. I would make sure that the stirring bar rotates at slowest possible speed (say, 30 rpm) so as not to raise up any slimes settling at the bottom of your beaker, and have them get trapped by the gold crystals forming at the Cathode; 2. Separating your Anode from your Cathode another few centimeters wouldn't hurt, again to prevent any possible impurities at the Anode. The process will take longer. 3. Hoke recommends 1.5v; a lower voltage will of say even 1v will help slow down the inevitable contamination of your electrolyte after repeated batches, as well as ensuring the purity of your final prodcut. Of course, this will take considerably more time, too.

[@SURFEAMORETERNO]

Well observed friend! 400mA / Dcm² of the cathode would also delay the operation much more, but would cause the gold to settle in metallic form.

[@AJ-ox6yi]

It's hilarious that you said morel mushroom. That's exactly what I was thinking. Maybe because that is one of my 2 favorite hobbies - gold and mushroom picking.

[@burlbark]

I had an experience exposing gold concentrates under a 2'x3' magnifying glass. Temperature exceeded melting point. The gold crystallized out of the concentrates very similar. My only conclusion is that the high concentration of UV light caused the crystalline growth. Very neat....!

[@justanotherfreakinchannel9069]

So, if it was 220.5g lighter with water than with the chloroauric acid, and there was only 160.5g of gold in the solution, does that mean that the same volume of aqua regia weighs 60g more than the water?? I would not have expected that, I always kind of had an assumption that the acid was less heavy per unit volume than water! 😅

[@richardwolanin4213]

It does look like a Morel mushroom! Our season for morels starts in about 2 weeks up here in Boyne City, Michigan.

[@MichaelClark-uw7ex]

Makes sense. When you add straight Hydrochloric to Gold, it won't dissolve because the atoms of Gold leave solution as fast as they are dissolved, the electric current causes the dissolved Gold atoms to follow the current flow and leave solution at the cathode end of the current flow. You're taking advantage of the natural reaction, very tricky, well done.

Thank you now I understand

[@SpartanONegative]

You made it look easy. Thank you for showing us how to do this. God Bless 🙏

[@olawlor]

4 amps seems a bit high for that small of a cathode; it's likely to be a bit less fuzzy if you grow it more slowly at lower amps. I've never done gold, but when the anode and cathode are the same metal with copper or silver, you only need a tiny voltage, 0.1v or less, to push the ions across successfully, and the slower they move, the more ordered the crystal. Of course, Faraday's Law tells you how much longer it will take to move a certain amount of metal over, and it can take a week to get a few grams at low currents.

[@sreetips]

I was going by the instructions in the book. I had zero experience with this.

[@buggsy5]

@@sreetips Yep. The book is concerned with recovery and refining of precious metals. Getting pretty crystals is of zero interest. But Orion is correct, a lower current density will produce larger crystals.

i would love to see this experiment re-ran with the same level of detail you showed to the setup being applied to all variables involved. You spent so much time setting up the physical layout but paid absolutely no mind to ensuring you had a top notch, low noise, near to perfect constant-voltage power source or any top tier temperature regulation. Imagine this done with the perfect physical layout, perfect power regulated source of current, and the temperature was controlled down to the thousandth of a degree.

Thanks Sreetips, awesome video! are you sure that the first bottle precipitate was metalic gold? it looks like gold chloride crystals to me, perhaps the solution became over saturated at room temp and that causes gold chloride cristals to precipitate.

[@TheReapersGrim117]

Hey sreetips, not sure if using water in the beaker to measure the difference in weight is the proper way to make an apt comparison due to the difference in density of electrolyte and water. I believe the correct scientifically accurate measurement would be to add the leftover electrolyte back into the beaker and measure from there - someone correct me if im wrong only commenting bc this channel is awesome and i love how accurate it tries to be; great vid!!!

[@shayne3190]

Outstanding. Was waiting a long time to see this. It's 5 p.m. Eastern and still no bids with 5 hours left to the auction. If it doesn't sell, makeup one gram packages for $100 starting bid on each. I'd gladly pay that, these crystals are special, but not easily liquidatable bullion. To get 1700 Worth, as a curiosity, is beyond my means. Second comment / question is: I noticed that you're keeping your silver cell free of any base metals buy re-refining crystal, but wasn't an excess of copper creating more interesting crystals? I thought you had mentioned something like that. I wouldn't end this experiment, to see larger crystals would be awesome, as well as more valuable. Again, outstanding job. Thanks

[@Rob337_aka_CancelProof]

I found calculations on a website that using displacement highway is graduated cylinder and a scale you could not only determine whether a gold was real but also its purity 10 karat versus 14 karat versus 18 carat Etc which is accurate enough to eliminate the need to buy expensive reagents for testing so yes it most certainly will be differences in density especially at that concentration

[@thomasoberg227]

While refining gold would it not be really convenient to just do the nitric boils and then just make an anode of the powder or even make a basket for the powder to use as an anode to eliminate the aqua regia boils?

[@sreetips]

The only problem is lead. Just traces of it ruins the ductility and malleability of gold. Doing a single refining with aqua regia and adding a little sulfuric acid to precipitate out the lead, then filtering it out will remove 100% of the lead. The anode for the electrolytic gold cell needs to be high purity to begin with.

[@mnn136]

Maybe an Odd Question and perhaps I've mis understand: If you have 100ml solution with 34.1 gram of desolved gold (state your calculation note) + you've desolve 25,5 gram of Pure gold (Anode) and after the experiment on the Kathode you've got 27,7 gram of Pure gold.

I understand that one of themanide or cathode basically pushes the metal over to the other side to stick to the opposite rod, my question is can you use a carbon rod to do the pushing ?? Does it HAVE to be metal?

[@sreetips]

Yes, I think the big refiners use titanium cathodes for the gold to plate out on instead of pure gold cathodes. I’ve never heard of carbon cathode, but that don’t mean it wouldn’t work. For electrolytic refining to be successful the anode must be fairly pure to begin with. Otherwise the chloroauric acid electrolyte would become fouled rather quickly and other metals could then contaminate the pure gold at the cathode.

And thanks for answering my question

[@MikkellTheImmortal]

Hi Sreetips. Why do the instructions say to use a silver clip on the cathode?

[@sreetips]

Don't know for sure. But probably because silver is the best conductor of all metals.

[@MikkellTheImmortal]

@@sreetips really?! I thought gold was the best conductor. Well if this is the only thing I learn today I know I'll be better for it. Thank you

[@sreetips]

Gold resists corrosion better than silver. That's why gold is used on electrical contacts.

[@buggsy5]

@@MikkellTheImmortal Both silver and copper are more conductive than gold.

[@BrokenTWelder]

Are you going to make any more of this?

[@sreetips]

Since it worked so well, and the gold produced was absolutely incredible, I may give this another go in a future video. It might make some cool framed art. Back when I did this about a year ago, I tried to sell it. But nobody knew what it was so it just didn’t sell. I had to melt it into bars to be able to sell it.

@@sreetips if you decide to make it again I'll definitely buy it from you. Had I been watching your vids a year ago I would've bought it the first time too.

What was the electrolyte? It sounded like clonal-auric acid? Thx

[@sreetips]

Chloroauric acid (pure gold dissolved in aqua regia)
