Thank you so much, Sr. for taking us with you as you build the gold cell. This is going to be very interesting. You know we can't wait to see what the crystals will look like. I said "interesting" and I meant awesome. LOL That was just under $10k worth of gold in those little nuggets of shiny. Imagine panning out a sluice run and getting a gold pan full of something like that.
Did you use lab grade hydrochloric and nitric? The cheap stuff could contain some impurities. Very interesting series. As a chemist I love to see you working with respect to safety. You are a real ambassador for the hobby.
I think I am finally starting to understand these processes for refining. Fascinating my friend. I finally get to go home tomorrow. Prince George was never a place that I liked to go to in the first place. So on Thursday I hope to get at our project. WOOHOO !
Thanks for making this video. I've been wanting to do this for years and your video was the perfect tutorial. SUCCESS! I had 3 oz of good clean placer gold that I ran the Miller Process (x2). Used 1 oz for my anode and the remaining gold in solution. I used a thin titanium plate as the cathode and the gold clings but comes right off afterwards. No scraping, just a spray bottle to remove it. Happy New Year Sreetips!
i like how you channel thy inner nerd...it definitely seems like you read alot and do more than enough homework and like learning......its sad there's people out there that run from learning anything as if being dumb as hell is cool....
9 months!! I remember very well when you mentioned doing this video, it was in June 2019!! I'm excited to get to watch this series!! A friend of mine asked if I knew what chemicals went into gold recovery!! To say the least I was thrilled to tell him what I knew! I also told him about you!! He should be watching your vids already or very soon! I don't know his UA-cam name, but I look forward to him watching your vids so we can talk about it!! Oh yeah, he's a friend from Church! What great conversation that'll be every Sunday! 😞 Have a GREAT Day!!!
Nice... I hope to see the rest of the process done soon... I know you must have a lot of stuff to do so i can wait patiently. 😁 also... I liked the paperweights you used to hold down the pages of the book. 👍 world's most expensive paperweight.
glad you're already aware of the problems with stirring up the annode sludge. i electro refine copper, can't stir it. your process would still plate, just more slowly.
Travis, I've never done this before, my first time. I intend to use three nines gold for the anode and electrolyte. Shouldn't be any sludge. But we'll see.
I've really been waiting for this series of videos. The first downside for using this method at home is already apparent. It takes fair amount of gold to start with. The second would seem to be that, even if you get the process just right and manage .9999 or even .99999 pure gold, I doubt you'd be able to get enough of a premium over .999 gold to cover the time and needed lab verification. It's still an interesting bit of metal refining chemistry. You definitely don't want any mishaps with that amount of gold in the solution. That's the price of a car in that half liter.

I don't have a 450 amp power supply. My cell will be tiny compared to what I read n the book. But it should produce some nice gold crystals. We will see.
That electrolytic fluid has a spot price of over $8,000 dollars! I assume this is a purely scientific exploit. I don't see the purpose of this if you have to start with a gold anode of 98% purity, A pure gold cathode, and over 8 grand sunk into electrolytic fluid. You already have to refine the gold scrap to get anywhere close to 98%. Might as well just chemically refine it to 999. Plus you will be adding impurities into the chloroauric acid, which will have to be refined out at some point to recapture the gold in solution. I don't foresee the markup on gold crystals over pure gold bars being enough to warrant the setup cost. I'm glad you are doing this on camera because I would probably never attempt it.
Well said. The Wohlwil process is not very suitable for a small-time hobby refiner. It's been requested many times so I'm gonna make the video (if I can pull it off). The anode bar will be three nines. The electrolyte, three nines, and the cathode is four nines. We just want to see some nice pure gold crystal forming on that cathode. I've never seen pure gold crystal except in a picture.

I've heard of it but I've never read it. Hoke is favored because it's written in non-technical terms. No chemistry at all. A pure lamen can pick it up, read it, do what it says, and become a proficient refiner.
I'll bet that I could get the volume down from about 475ml to under 300ml with evaporation. Maybe even lower. 5 troy ounces of gold n Nader 300ml of liquid. I wish that I would have weighed the bottle before I added the chloroauric acid solution.
@@sreetips Apparently some of the gold crystallizes out of solution if the solution becomes to concentrated. That could happen if you dissolved as much gold as possible in the AR making sure all the nitric acid was used up - then cooled the solution. That is probably why Hoke specifies an excess of 10% HCl.

If I may ask... What's the point of using an electrolytic gold refining cell if you're already starting with .999 fine gold in the first place? I'm not trying to be contrary, I'm honestly curious.
@@sreetips okay, thanks Sreetips. I wondered if it was just for fun or if there was some financial benefit to trying for four 9's fine instead of .999 fine gold bullion.
Let's say you were to drop that solution on the floor, shattering the container and the solution spilling everywhere. Could you show us the process in how you would recover it and get it back to pure gold?
@@sreetips ive seen the one where u used a rolled out piece of gold . but im referring to a cell like your silver cell where u have a basked on top and a steel bowl . insead of growing silver crystal would it work for gold
@@prospectorpete It wouldn't work. The excess HCl in the electrolyte would attack the stainless steel and the heated solution would make it even worse. HCl attacks ALL stainless steel formulations. There would also be galvanic corrosion of the deposited gold, although how that would be affected by the electrolysis current is unknown to me.
Gold concentration recommended is 80 to 100 grams of gold per liter concentration. So I'd need 40 to 50 grams for a 1/2 liter cell. I don't think there is a substitute. If you don't have the gold then you can't build the cell.
1. To show that you can. 2. It was requested. 3. The silver will be very close to five nines fine. 4. I suspected that batch had some palladium in it so I set it aside for re-refining.
Your calculation of the amount of gold in the electrolyte is close, but not precise. I suspect that there may be a few grams of gold in your rinse solution. But since the absolute gold concentration in the electrolyte is not very critical, it really does not matter. What is most important is to ensure all the nitric acid was used up - thus the excess of HCl and undissolved gold left over after the digestion.

Did you use pure gold for the anode, electrolyte and cathode? Electrolytic refining only works when everything is very close to high purity in the first place.
In the beaker, while its being dissolved, tiny droplets of gold can leave the beaker and go up the stack. Keeping the beaker covered during the reaction will minimize this loss.
Fun fact: Did you know that putting gold into solution is the real reason why you aren’t allowed to bring outside drinking containers with you on aircrafts? It started out only on international flights as people were smuggling gold into the country in this fashion illegally evading customs... so when you hear anything about possible explosives on aircrafts in the form of liquid being the reason you aren’t allowed to bring your own drinks with you, you can know the real reason now... food for thought...
Source please? Because the official explanation has some solid chemistry behind it. There's a quite dangerous explosive you can make from two readily available clear liquids that could easily pass for water if you didn't open the container. Whereas smuggling gold in solution sounds like an absurdly small problem. Gold doesn't get any lighter when you dissolve it. So how much can you carry?
I bet that I can get that solution down to 300ml with evaporation. Then I'd have eight grand in just 300 milliliters of liquid! And guy is right, that solution is heavy. I'm going to weigh the bottle with the chloroauric acid solution in it. Then replace it with the same amount of water and weigh it again. Neat experiment.

They are electro-refining many pounds of gold at once. That is also for 3 square feet of cathode area. So 150 amps at 1.5 volts would mean you need only 12.5 amps for a 2" x 6" cathode.

Thank you! That really helps me out.
Where does the name Sreetips come from?
My last name (peters) spelled backwards
I would really be intrested in buying one of those books. Are you able to link a website where they sell them?
I know at one time someone had a link to a digital copy on gold refiners forum. Might check there.
You can get a free PDF copy off the goldrefiningforum.com, print it out and use it in the shop. You can buy a nice new hard bound copy at gesswein.com type "Hoke" in the search block. Keep that copy on your night stand in the bedroom.
sreetips awesome thank you so much
what is the name of this book?
Refining Precious Metal Wastes by C.M. Hoke. You can download it for free on the goldrefiningforum.com or you can buy a brand new hard copy at gesswein.com type “hoke” in the search block.
Is the electrolyte battery acid?
No, it’s gold chloride (chloroauric acid)
@@sreetips thank you
sir why did you use 1/5 as multiply ?
Because the formula called for liters. I used 200ml so 200/1000 = 1/5
Sir after you multiply you got 170g/l but last you got a pure gold bar 27g so where is 170g ?? Sorry about that
I was interpolating.
What's the name of solutions
It depends on what’s in them
hey if for sale what's your price
Sorry, that bead has already sold and been shipped to the buyer.
I did that sane process in hooks book but I got a white precipitate that ended up being gold not crystal tho
Did you use pure gold for the anode, electrolyte and cathode? Electrolytic refining only works when everything is very close to high purity in the first place.
That solution is worth $8,411.15 or £6,566.58. Dont spill any.
hello can gold rise with steam?
Possibly, but very little
sreetips why gold rises because it is heavy?
In the beaker, while its being dissolved, tiny droplets of gold can leave the beaker and go up the stack. Keeping the beaker covered during the reaction will minimize this loss.
sreetips although I don’t speak English, your video helped me a lot. Thank you very much!
sreetips how can silver chloride be dissolved?
Fun fact: Did you know that putting gold into solution is the real reason why you aren’t allowed to bring outside drinking containers with you on aircrafts? It started out only on international flights as people were smuggling gold into the country in this fashion illegally evading customs... so when you hear anything about possible explosives on aircrafts in the form of liquid being the reason you aren’t allowed to bring your own drinks with you, you can know the real reason now... food for thought...
Source please? Because the official explanation has some solid chemistry behind it. There's a quite dangerous explosive you can make from two readily available clear liquids that could easily pass for water if you didn't open the container. Whereas smuggling gold in solution sounds like an absurdly small problem. Gold doesn't get any lighter when you dissolve it. So how much can you carry?
I bet that I can get that solution down to 300ml with evaporation. Then I'd have eight grand in just 300 milliliters of liquid! And guy is right, that solution is heavy. I'm going to weigh the bottle with the chloroauric acid solution in it. Then replace it with the same amount of water and weigh it again. Neat experiment.

Also my folks both are retired from American Airlines ( dad retired as head of baggage from Boston Logan Int’l Airport and my mother narrowly escaped death on 9/11 being that she traded shifts with another flight attendant friend to attend my lil sis’ school play) with 55 years combined total service. They told me about this right around the same time frame as 9/11
@@whatchoobeezbout From the article: "Customs officials say such a modus operandi has not been recorded at Chennai or any other airport in India in the recent past." So yes, it's happened, but it isn't be a big problem.
You teaching classes yet?
Only via video on my UA-cam channel.
You did it again, violating the coinage. Your better half would be on your case if she hears of it.
With all of his scrap gold I don't understand why he does this
Final Draft Canadian gold coins are a guaranteed purity and for this process having a high purity cathode is essential.
you cant trust american gold coins.
Christopher Cox US Mint are just as good. Pretty good chance that was what he had laying around
Actually it is possible to obtain canadian 4 nines fine gold with out destroying or defacing canadian gold coins.
Look and learn.

EN ESPAÑOOOOL!!
:(
450 amps?? Wtf?
They are electro-refining many pounds of gold at once. That is also for 3 square feet of cathode area. So 150 amps at 1.5 volts would mean you need only 12.5 amps for a 2" x 6" cathode.
Hey sreetips peace
Lol why does he write his name everywhere?
He would have to tell you for sure, but I know some time ago, his early videos were getting copied and put on youtube without his knowlege or getting credit. Think it's his way of everyone knowing where the video came from.
Branding. One guy had all 56 of my early videos reuploaded as his own creations.
So other people don't steal his videos and use them as their own.
@@sreetips I hope you dmca striked his channel or at least copyrighted all the videos on his channel.
he likes the sound of his own name. lol jk.
