When I worked in the gold room in a mine in Australia we would electrowin the gold from the eluate solution onto a stainless steel mesh anode. Once a week we would pull out the cathodes out and we would Gerni off the gold. It pretty well looked the same as your precipitated gold. We would vacuum the excess water of and then mix in fluxes and then smelt it. I like watching your stuff your cell is like a mini version of what we did eccept the gold we electrowinned was from out of the eluate solution.

[@kiwigurn]

So a stainless steel bowl might work? Gold cell

[@golder70]

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👍🏻

[@ego73]

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.]

[@sreetips]

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.

[@patrickmcgovern676]

I've loved watching you since 2018. Thanks for all the information and i hope to one day replicate the experiments that you have. Congratulations on all your success Patrick McGovern i remember when you were doing copper. Happy memorial day weekend and thank you for your service.

[@sreetips]

Same to you, thank you!

[@ut000bs]

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.

[@DavidRutledge1]

That was awesome. Much faster than expected. Thank you!! 🙏🏽

[@sreetips]

I think having the anode closer to the cathode would speed it up

[@MrTk6969]

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.

[@sreetips]

Good point

[@JP-kb5ng]

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.

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.

[@sreetips]

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.

[@Jinsyl-xi4by]

Great job Chief, another excellent video. Thanks Sreetips!

[@notsure2706]

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 ;)

[@sreetips]

I added numerous doses of hydrochloric acid to the cell to keep it hydrated. HCl improves conductivity

[@golder70]

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.

[@sreetips]

I’ll try another refining soon with a different anode bar and revised configuration

[@Pete87O]

ugh...my life has never been the same after i started watching these, and thus now doing it as an effect. had i been introduced to this in HS my life would have been dramatically different. (not to say im not doing ok, just i would have taken a completely different path).

[@sreetips]

Working with gold and silver has changed our lives for sure. And for that, I’m grateful!

[@golder70]

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

Excellent, thank you

[@sreetips]

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

[@renegonzalez8070]

I would rather watch your videos I learn more that way

[@CasutaCuRetete]

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

[@CasutaCuRetete]

I'm thinking, by this method you refine gold without using a lot of acid.

[@sreetips]

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.

[@scotthultin7769]

3 👍's up sreetips thank you for sharing 🤗

[@he-artLovesart]

I’m sorry I just wondered if the gold that is growing is just the gold coming out of solution?

[@MickTee2k]

Well, yes. The gold from the anode goes into solution. Gold from the solution is deposited onto the cathode.

[@sreetips]

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.

[@JP-kb5ng]

@@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.

[@sreetips]

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.

[@JP-kb5ng]

@@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.

She’s the best thing that ever happened to me!

[@sreetips]

Right now, the masses are still clueless about gold. Their faith in paper remains high despite the fact that paper is collapsing in value. Very few understand that hoarding stacks of paper is foolish (insanity). Holding savings in gold (and silver) is for the wise. But this is slowly changing. We used to find hand fulls of scrap gold every weekend just ten years ago. But it’s getting harder to find as folks begin to wake up to the scam of the money printers. You can’t measure anything’s true value in paper dollars because they can, and do, print “without limit”. Therefore, measuring value in dollars is insanity. It all boils down to this: money printing is insanity. The only way to protect your savings is to hold savings in real money, gold and silver.

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?

[@sreetips]

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

[@ClamChowder]

@@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!

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.

[@sreetips]

Insoluble impurities fall to the bottom of the cell. Soluble purities won’t deposit and get left in the electrolyte.

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.
