It’s out there. Because folks are clueless about silver and gold. The currency printers have made silver and gold incompatible. A barbarous relic. And they are still desperately trying to reduce real money (gold and silver) to mere “investments”. But as people slowly begin to catch on that paper is worthless, then the metals will become more difficult to find. We’ve already noticed that it’s getting harder to find.
Great video! Love your relaxed but enthusiastic way of talking us through the process. Wonderful how i can still keep watching gold refining video and not get bored of it!
Your work is soooo fascinating. I have learned an enormous amount of practical knowledge on a subject that I simply can’t get enough of. Thank you so much for sharing Mr. Sreetips. You do such great work and your respect for the subject matter and your audience comes through in every video.
a bottle or a beaker with 100g of gold in solution must be something rather interesting to handle. the feel of that heavy liquid flowing around. and the ice... just imagine having a long drink that heavy
That’s an amazing process sir thank you for all your hard work time and money you spend on these experiments you show us week after week year after year!
I got into making jewelry in part because of you. Of course now I can recycle the failures using you as a reference to remember all the stuff I learned.
This has got to be the most fluff ups you have done in one video, from gold splashing on the table to electrode hanger being to thin. It's good to see even you make fluff ups, even better you showed them in your video. Good stuff to know..
thats great sir i knew you would find the best way what you do and how much you know about this is unparalleled and the only channel of its kind you sir are a legend and love to watch you work brother
Thanks for taking us on these experiment journeys with you. It is obvious this is horribly inefficient, but the results look fascinating. Always something to learn.
I think I’ve been watching your channel for about 200 years, but this is the first time I remember ever seeing lead precipitate out after sulphuric acid treatment, even though you do it at every gold refining!
Good seeing the various approaches. Always interesting. Going forward I suggest you keep the DC power source out of the fume hood. Some of the acid vapours which turn up in that area will destroy electronics. Al alternate approach would be flexible heavy duty leads (similar to what you find in jumper leads of the middle quality) to carry the current and not fight your positioning too much.
First lead precipitation from H2SO4 I've seen on your channel Sreetips. I know you always put it in just in case but this is really cool because of the material you put in, the odds of precipitating lead was virtually 100%. That's really cool to see in action.
I understand you need to be quick to pour the gold when molten but maybe being more gentle on pouring can improve the overall aspect of the finished bar? I mean to avoid those blobs and holes. Or is it an unavoidable graphite mold problem?
Because the yellow liquid was gold in solution. I poured the SMB saturated waste of the gold in the beaker, and the gold from the yellow liquid precipitated.
I love these videos! I love the science and chemistry behind it. Streetips, if I may make a request, it would be fantastic if you could put the reactants and products for each chemical that you use. For example, when you use the Stump-out, show the reactants and products (equation) on the screen! That would be really cool for us nerds that like that kind of stuff. Thanks for your content! :)
Thank you - this channel processes allot of time Also. After watching the full jewelers carpet (1 sq yd) I again heard irritation in your breathing, you know I'm a docker, a piece of incense left burning UNDER THE HOOD while you take the parrot to the spa when you all return - the nose knows love ya but we all know its the glow of gold once it's heated up illuminations all over the room
I have reduced lung function because I ignored warnings about refining in my back yard without a fume hood. Also, blurry spots on my eye lenses due to nitric fumes
No contamination from the graphite as long as it’s clean. 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, and demonstrate that I can, and produce a new and interesting video for my channel.
I have a question when you precipitate the gold some was still in suspension could u add a surfactant to break that water tension allowing more gold particulate to drop from suspension I know u recover in waste jars (more wondering chemical wise if it will mess up the processes)
Question: in the fail attempt of the 14k Anode hanger does the amount of other metals comprising the 14k included in the anode adversely affect the purity of gold plated onto the cathode.
Yes I think you're right - the sodium metabisulfite dissolves in the solution, then gets washed away during the various boils/rinses/pour-offs. Some of it off-gasses as sulfur dioxide gas during the bubbling as the gold is precipitating.
Got this from “Butcher” on the goldrefiningforum.com Sodium metabisulfite in gold solution: Na2S2O5 + H2O --> 2 NaHSO3 Notice we actually make sodium bisulfite Then 2 AuCl3 + 3 NaHSO3 + 3 H2O --> 2 AU + 6HCL + 3 NaHSO4
Why is the inquarting part done? Does it help remove impurities or something? It seems to my uneducated self that it would just be easier to add the nitric acid without the inquarting, but there must be a reason it's done.
Should have weighed the hook before and after. Also, there may be more or less gold left in the electrolyte once the job was done. The electrolyte should start out saturated with gold.
Excellent video, thank you! Is the 9999 purity of the final gold bar a theoretical value due to the electrolytic refining method? Do you know if there’s an analytical method to determine the actual purity?
Only to you, the viewer, if you like seeing the gold refined electrolytically. 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.
how much do all the chemicals cost you to do this? That must be factored in... but there's nothing like pure gold. That brightness in the shade is unmistakable.
great video , you could get a custom mould made so when you pour a anode bar it also makes the long thin bit for hanging at the same time. after you use it down to its nub , toss the nub into the next melt.
Sir, could I please ask why you haven't used a titanium bowl and made a system similar to your silver cell. You can get decent sized bowls in titanium for camping. Just curious is all. Thank you for you videos. I enjoy each one. Have a great day.
Given your amazing expertise in precious metal chemistry, have you given any thought to attempting to create some of the other gold mixes like rose or purple? Excellent video as always.
Just wondering if it would work the same way as your silver cell as a gold cell. Make all your scrap into shot and process the same to get gold crystals. Would save a ton on chemicals and reagents.
I didn't watch this one, but good work team. I know it was good work for sure. I'm not watching your content now, not because I don't like it, I do, but I have very little spare time now. But while I did, it was an amazing journey.

7:26 Impressive transfer of the ice without a splash! I didn't know that 7-Eleven sold lab equipment?! My wife and I are truly fascinated with your work! Expecting to try our first silver cell next year!
Sreetips just a suggestion or request per se I'd like to see a video where you break down and explain all the precautions you take for safety measures working with these materials. I tried searching your old videos but never found one that outlined that. I know a lot is common sense but It may be very helpful to some and I bet it would get a lot of views.
I think a highly polished plate of pure chromium would make a better cathode. A mild steel spatula is not going to scratch chromium, and the highly polished surface should aid in releasing the gold deposit.
I think reversing the polarity of the cell for like 1 second would cause all the gold to pop off. But he'd probably want to do that in a different batch (or type) of electrolyte, so that would add another step/hassle. He might also try putting the cathode in the freezer overnight, the contraction caused by lower temps might cause the gold crystals to fall off.
@@sreetips then it was rely pure to start with. how do you think it will work on a bar made directly from jewelry? is there a minimum gold content needed?
Another great video! Hey, after you added the Stomp and let the gold precipitate out, I noticed some specs floating at the top. What is that floating stuff? Is it lead?
Well If I had watched longer you answered it my dad was a chemist and he ran a gold sample for me years ago and I kind of remember what he did and he did something with I think mercuric chloride and some sort of thing that started with kind of like strontium but it wasn't I can't remember what it was called and he did something with tin also
Mercury will dissolve the gold and create an amalgam of gold and mercury. The amalgam is then heated and the mercury burns away leaving the gold behind.
@@sreetips I have 4 Oz's of 21k gold and I want to purify it, planning to inquart it with copper but I don't have graphite rod, can I use iron rod or just shaking the molten without stirring is enough to have homogeneous inquarting gold?
It is better to create the cathode with 1000 purity graphite bar. They can be cut with diamond discs so there is no possibility of contamination of the lower alloy. I use a flat bar and modified the ingot part so that the gravitation bar is half the height of the ingot plus a square on the bar to avoid spilling the casting. I also suggest that you apply electroplating to the crocodile clips to prevent corrosion of the metal with rhodium or platinum plus a heat shrinkable sleeve to protect the visible area of the copper. Also the soldering part of the clamp to copper can be insulated with silicone without sections so that corrosion does not get inside the main cables. Another method I use is a perforated crucible and add there is the shot the graphite is never damaged in the electrolytic acid for massive electroplating
Do you have a Commercial fume hood or is it a self built one? Do you have any type of scrubber on the fume extraction to deal with the nitrous oxide fumes?
@@sreetips I get it I just didn't know if you had to have some kind of certificate to do it or if like I can just order the chemicals to do the same thing
I have a question - have You tried a centrifuge to make the metal settle quicker? or is it completely impossible to make one reliable enough to try it?
It takes longer and it’s more pure. But I like the gold that it produces. This is the process that big refiners use to get four nines gold. The anode should first be refined with AR to get the lead out.
On the finished bar, what is that pink nodule? I'm guessing that it's flux from the melt dish? Interesting video, thanks for posting. I don't understand exactly why, but there is something relaxing about watching these.
Consider just welding the gold hook to the anode bar with another piece of gold? Ive seen you make gold repairs, so im confident you have the skill to do that. 👌🏼
The timelapse at the end with the electrolysis eating away at the gold bar was marvelous.
Indeed, not only does it look awesome but I've never seen that before.
It was like watching a popsicle slowly dissolve exposing amazing crystal formations under the exterior.
why did he do this second time can u explain electolysis for gold bar like why he got bar then why did he do it second time

Now that I’ve looked at it, it does look exceptional.
Thanks for taking us on these experiment journeys with you. It is obvious this is horribly inefficient, but the results look fascinating. Always something to learn.
Actually, just about all pure gold bars or coins are refined like this, only on a much larger scale.
One of my favorites. Even though you had mistakes you didn’t edit them out. Thumbs up 👍🏾
I think I’ve been watching your channel for about 200 years, but this is the first time I remember ever seeing lead precipitate out after sulphuric acid treatment, even though you do it at every gold refining!
That’s because I actually seen some lead solder on some of the karat scrap in this lot.
Really cool experiment SReetips. Best gold purification on the 'tube!
Good seeing the various approaches. Always interesting.

Always amazed at how professional you are at recovering precious metals. I am not so inclined to do this myself as i am no chemist by any means.
Thank you for the video, I liked seeing from start to finish in one video.
dude the way the anode bar reveals the crystalline structure underneath the surface as the cell eats it is so cool
Mr. Sreetips in what situation do you use the “specially prepared” filters? Thanks for the fascinating content!
Gold filled
I understand you need to be quick to pour the gold when molten but maybe being more gentle on pouring can improve the overall aspect of the finished bar? I mean to avoid those blobs and holes. Or is it an unavoidable graphite mold problem?
The key to a perfect bar is to get the mold real hot.
I love watching people in comments freak out over Your spilled gold bits.
Gold Fever is real. Funny, but real. 😁
That never would happen if not for the camera in my way.
196th! Haven’t seen this procedure done before now. Very interesting. Roger in Pierre South Dakota
@14:50 why has the gold-refining-waste beaker suddenly changed its color and transparency ?
Because the yellow liquid was gold in solution. I poured the SMB saturated waste of the gold in the beaker, and the gold from the yellow liquid precipitated.

Does the wet gold get contaminated at all with graphite from the mold ? Does three nines sell for different than four nines?
No contamination from the graphite as long as it’s clean. 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, and demonstrate that I can, and produce a new and interesting video for my channel.
I have to agree the time lapse is crazy the gold looks like it turns into a crystal
The next run you do with the karat scrap electrolytic Gold cell is love to see the gold from the titanium under a microscope😏👀👀👀
I have a question when you precipitate the gold some was still in suspension could u add a surfactant to break that water tension allowing more gold particulate to drop from suspension I know u recover in waste jars (more wondering chemical wise if it will mess up the processes)
I could have stirred it up and got all of it to settle. But instead, I like adding it to my waste container and let it accumulate.
I get that makes for a nice waste processing video
What’s the reason for not pouring the new gold over the shark tooth sitting in the mold where it was originally formed?
Didn’t think of it.
@@sreetips fair enough. Was wondering if there was a reason that didn’t occur to me.
I have nothing negative to give, we have opposition in all things. When you do good you will draw some negative. Keep up the good work please 😃
Question: in the fail attempt of the 14k Anode hanger does the amount of other metals comprising the 14k included in the anode adversely affect the purity of gold plated onto the cathode.
No
Where does the stump out go when you do the precipitation, does it get washed away with the follow up boils and rinses before the melt?
Yes I think you're right - the sodium metabisulfite dissolves in the solution, then gets washed away during the various boils/rinses/pour-offs. Some of it off-gasses as sulfur dioxide gas during the bubbling as the gold is precipitating.
Got this from “Butcher” on the goldrefiningforum.com
Sodium metabisulfite in gold solution:

Notice we actually make sodium bisulfite
Then
2 AuCl3 + 3 NaHSO3 + 3 H2O --> 2 AU + 6HCL + 3 NaHSO4
Why is the inquarting part done? Does it help remove impurities or something? It seems to my uneducated self that it would just be easier to add the nitric acid without the inquarting, but there must be a reason it's done.
It reduces gold concentration down to 25% so the nitric can penetrate
@@sreetips Ah, I see. Thanks for the clarification!
Was the loss was expected from impurities from lead? or just a bunch went into the vial of "to be continued"?
Should have weighed the hook before and after. Also, there may be more or less gold left in the electrolyte once the job was done. The electrolyte should start out saturated with gold.
There’s probably 8 or 10 grams of pure gold still left on the back of the cathode.
@@sreetips ahh roger
Excellent video, thank you! Is the 9999 purity of the final gold bar a theoretical value due to the electrolytic refining method? Do you know if there’s an analytical method to determine the actual purity?
ICP analysis.
Looks like the same refining of the other bars. I mean it's not much shinier! Do you think it makes any difference going through that process?
Only to you, the viewer, if you like seeing the gold refined electrolytically. 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.

The anode produced some sludge into the electrolyte while dissolving. Did you filter the electrolyte to see what that was?
Not yet, I’ll do it before its next use.
how much do all the chemicals cost you to do this? That must be factored in... but there's nothing like pure gold. That brightness in the shade is unmistakable.
I’d say less than a hundred bucks, not counting the gold.
Would painting some insulation on the back and sides of the cathode help to grow the gold only in one spot?
Or would a pure gold cathode work ?
I’ve used pure gold cathode, works beautifully. I’d hesitate to paint anything on the cathode.
Mr sreetips, what kind of fuel do you use in your torch? Oxygen/acetylene? Oxygen/propane?
Oxy/acetylene.
great video , you could get a custom mould made so when you pour a anode bar it also makes the long thin bit for hanging at the same time. after you use it down to its nub , toss the nub into the next melt.
Getting it all off of the plate is the issue with time savings?
It seems there's a bead of solidified flux on the end of the bar?

14:57 bonus precipitation from waste solution.
I think a highly polished plate of pure chromium would make a better cathode.
A mild steel spatula is not going to scratch chromium, and the highly polished surface should aid in releasing the gold deposit.
I think reversing the polarity of the cell for like 1 second would cause all the gold to pop off. But he'd probably want to do that in a different batch (or type) of electrolyte, so that would add another step/hassle. He might also try putting the cathode in the freezer overnight, the contraction caused by lower temps might cause the gold crystals to fall off.
Curious - how do you know it's 4x9s and doesn't have, eg, titanium impurities either absorbed or from scraping off the cathode?
There’s going to be some titanium from scraping. But parts per million only. Not enough to report in an assay.
no stir bar this time ;) what was left in the beaker this time?
A few pieces of gold crystal.
@@sreetips then it was rely pure to start with. how do you think it will work on a bar made directly from jewelry? is there a minimum gold content needed?
That would foul the cell quickly because of the base metals in the karat scrap.
At the 1445 mark what was floating in your liquid you were dumping 1st dump
A little bit of gold.
May have been some dust particles or other trash that fell into the electrolyte.
Or some gold
Another great video! Hey, after you added the Stomp and let the gold precipitate out, I noticed some specs floating at the top. What is that floating stuff? Is it lead?
No, those were pieces of pure gold attached to tiny bubbles. I added that to my off-line savings account (temp waste container).
When you are dissolving the gold, is there gold in the fumes?
Probably
May ask what that orange circle is in the finished product?
Borax
Aquaregia aka Royal water? @ 5:25 and the sufuric precipitates the lead?

Heat cause it to darken like that. It turns from orange/red to more yellow as it cools.

Graphite rod

Is the electolyte process quicker than the aqua regia method?
No
It is better to create the cathode with 1000 purity graphite bar. They can be cut with diamond discs so there is no possibility of contamination of the lower alloy.
I use a flat bar and modified the ingot part so that the gravitation bar is half the height of the ingot plus a square on the bar to avoid spilling the casting.
I also suggest that you apply electroplating to the crocodile clips to prevent corrosion of the metal with rhodium or platinum plus a heat shrinkable sleeve to protect the visible area of the copper.
Also the soldering part of the clamp to copper can be insulated with silicone without sections so that corrosion does not get inside the main cables.
Another method I use is a perforated crucible and add there is the shot the graphite is never damaged in the electrolytic acid for massive electroplating
Sounds like you’ve done it a time or two. Good suggestions, thank you
Would the electrolytic process leave the lead behind as it would other impurities? Then you would not have to do the initial refining?
Not sure, so due to lack of experience, and for insurance, best to refine it with Aqua Regia first to get the lead out.
One of the most outstanding videos to date. 👊🇺🇸🧂
Do you have a Commercial fume hood or is it a self built one?
Do you have any type of scrubber on the fume extraction to deal with the nitrous oxide fumes?
I bought it on eBay. No scrubber. The fumes are nitrogen dioxide.
On the final little bar, what is that pink bubble under your right thumb?
Borax
Does your city have any regulations against doing this like do you need a license to do this or get any of the chemicals for doing it
No
I’m not a business. This is my hobby.

I get most of my chemicals off the shelf at Ace Hardware.
I have a question - have You tried a centrifuge to make the metal settle quicker? or is it completely impossible to make one reliable enough to try it?
I have a centrifuge, but I rarely use it.
So is the gold cell process cheaper as it’s less chemicals and steps than the aqua regia and stump out? Or is it just more pure?
It takes longer and it’s more pure. But I like the gold that it produces. This is the process that big refiners use to get four nines gold. The anode should first be refined with AR to get the lead out.
I can't believe you melted it. I thought you were doing all this to keep it in crystal form. It's worth more than bar form.
Same
