Recover The GOLD From The Burnt Gold Chloride

[@JohnnyFlynn76]

if someone told me as a child that when I grew up I would spend hours watching videos of a guy refine precious metals I never would have believed them. Sreetips and the Hoof GP guy who trims cow hoves are my favorite channels to watch on youtube these days

[@pennybridgefreeriders]

Hahah iknows right, getting the goldfever by watching this homecook mad scientist 🤣🤣❤️

[@wolflarson100]

Yep!

[@hannable3871]

I like watching them both as we'll.

[@eacord6499]

You could be watching something worse. At least those 2 channels are educational and entertaining.

[@PaulBrown-uj5le]

Hoof gp.... is he the Irish or the Scottish guy?...

[@tom23rd]

It was incredible to see some of our questions demonstrated as a sorta "let's do it and see" experiment. Added a bunch of anticipation after the previous cliff hanger, and made for a special experience. I can't thank you enough for the creative treatment of these topics boss 😊

[@johnmccormick650]

Really enjoyed these last couple of videos. looking forward to the silver cell time-lapse. Thanks again Sreetips 👍

[@elbybrook9466]

I knew it was still there. You can refine gold, you can melt gold, you can evaporate gold, but one thing you can't do is destroy gold. If you can destroy gold you can make gold.

[@sreetips]

However, you can cause it to go up in smoke, literally. Beautiful purple smoke. While you cry over seeing your gold vaporize into thin air.

[@tombrooks3812]

I really enjoy watching you work thru a problem, you dont let it get to you. Just figure out how to continue and get her done. thanks another great video✌️

[@1911darkstar]

Excellent series Sree. Have always wanted to see the H2SO4 reaction with lead. The crystal chloroauric was really interesting as well. You’ve been upping the game lately, switching up methods, adding some new production aspects. Well done.

[@sreetips]

Thank you

[@JFEnterprize]

@@sreetipsdo you have vids of how to reclaim metals from electronics? Is such possible for diy’rs? I see on eBay guys are selling brass lumps with metal in them. Would like to see a semi-pro reclamation of one of those if you havnt done one yet. My single and double displacement math isn’t sharp and not sure if Frey scientific still readily ships these chemicals to homes or else I’d possibly attempt so myself. 🎉❤

I was really looking forward to this video

[@jamescball55]

I really enjoyed watching these two videos. This is what I call testing a positive control. The test being "Does sulfuric aclid really precipitate out lead contamination?" I think you answered this question. It would be nice, however, to get some elemental analysis of this sample of gold to verify you have not lead in it. You have a nice little chunk of gold that could be sent our for analysis.

[@Jultsu]

This! Bumping so sreetips would see it better

[@mouserr]

the peroxide mix was much better a choice than my suggestion but yeah the gold wouldnt be lost in the overcooking so i figured it was just a matter of rerefining ... and it was

Arkansas's middle section is folded and fractured. As the Caribbean plate was forced into and under it water boiled up through the cracks. Every time i see you dissolving and percipitating minerals i think of home. Today i was looking at 2 billion year old sea bed that had mercury sulfide forced up a thousand feet above the sea level. I cant help but compare it to the vents at Yellowstone. Thanks for the videos.

[@sreetips]

Geology, mining, and refining are related.

[@chemistryofquestionablequa6252]

That's really cool to know. We moved to North central Arkansas last year, the Heber Springs area where my wife's mom is from. What area were you seeing the sea bed in?

[@sreetips]

I’ve never seen that sea bad.

[@Michael-rg7mx]

@chemistryofquestionablequa6252 Northern Missouri was the South tip of rock in North America. The sea bed sloping away to the South. When small animals began they grew a huge coral reef where the sea was shallow with mud sloping deeper to where the gulf of Mexico is now. First Africa bumped into the East side so hard that it crushed the sea bed and folded it upward forming the Appalachian islands. It slid under the North American plate raising it upand folding where the Mississippi River now runs. Then South America came North. It smashed into the Caribbean and rode over it pushing it into North America and under it. Places where there were coral like Northern Arkansas and Florida had their reefs killed as they raised up out of the water but new coral grew in the warm shallow waters. In Arkansas it pushed up from Little Rock to Oklahoma a string of islands so fast that no coral grew. The Quachita Islands. The land fractured down like the Mississippi River did but this time East to West where the Arkansas River now runs.

[@chemistryofquestionablequa6252]

Wasnt worried a bit! Had the faith in knowing youd pull it back from the brink. The Mrs can relax now.. 😂 BTW, excellent shot of the gold flowing from the dish on the pour!

[@MichaelPhillipsatGreyOwlStudio]

It's funny, you know, but every time I see the gold in the dish ready for melting, it always looks like you're about to feed the cat! 😂

I think it looks like my grand kids diaper….

[@PaulBrown-uj5le]

​@@jimalcott760haha me too😊

[@paulslund1]

If you look really carefully from about 17:00 onward it appears that there was a chunk of gold stuck to the outside of the crucible near the spout.. then when you poured it the heat melted it and it fell off when you set it back down.. at least that what it appears to be to me...

[@SuperDavidEF]

I just watched it again and you're right. The gold piece was already stuck to the outside of the dish.

[@Mobile_Dom]

this sketchy backyard chemistry is one of the reasons I love YT, this is the heart of YT for me. proper equipment? how about casserole dishes from the charity shop. official hoses? how about garden hose. proper sealed tubs? home depot anyone. i love this, and the fact it all works so bloody well, its amazing

[@PetraKann]

Standard lab equipment is being used here. The porcelain dishes are a precaution in case the liquid overflows during boiling or the beaker cracks and leaks which sometimes happens. He uses a fume cupboard. Very safe and professional set up at home

[@nunyabisnass1141]

That's what I liked about chemplayer. Boiling MnO2 in KClO to make permanganate over a kitchen stove. Would never try that myself but it was interesting.

[@PaulBrown-uj5le]

I knew you'd have to use hydrochloric acid, what I didn't know was you'd have to add a little more h2o2 to get the more stubborn bits to re-dissolve, another fascinating video Kevin ty very much😊.

[@sitnw8nw840]

thank you sir, i enjoy watching your videos.

[@SMOBY44]

Wow! That double eye pour surface is awesome. Looks like the bar is looking back at you. And I think that little straggler was the final drop from the pour as you lifted up. Thanks for another great video! You covered a lot of ground with this one.

[@davidburton3447]

Not a chemistry major, but it seems to me that when you heated the gold solution to dry, you just removed water out of the equation. everything else was still there. Personally I would have started with distilled water, added some heat, and see what happened. You essentially did that, though more expensively, with the hydrochloric acid {HCL + H2O) and Hydrogen peroxide (H2O2 + H2O) I observed that it was starting to dissolve in HCL, but looked like it ran out of water to suspend it (I know it is technically acid, but it's the water that is keeping it suspended) Then you added H2O2, and viola, it all started to go. My theory is that the H2O2 was giving off the extra hydrogen atom into the atmosphere leaving nothing but pure water behind. Which leads me back to my original thesis.The gold was already broken down and bound to the nitrogen, hydrogen, and chlorine. all of which are water soluble. No need to make another aqua regea (sp?) it's all there minus the water. Would be cool, now that you know you can recover if you could test my hypothesis with say a button's worth or just try it next accident. I'm pretty sure I'm right and it'll save you like $30 in chemicals next time.

[@redbaronrefining5322]

Glad to see more boiling of the precipitated gold! Crazy how fast it’ll settle! After you perform an an HCL rinse, if you want to try something different to show the audience and clean the gold up a tiny bit more, rinse the hcl with distilled well, and then add some distilled water and about 15% sulphuric acid and then boil again. It will clump all your gold powder together into a nice ball you can pick up with your fingers and just set into the melt dish :)

[@sreetips]

Good suggestion, I’ll give it a try.

[@redbaronrefining5322]

@@sreetips awesome! I look forward to it!

[@sreetips]

Actually I’ve had this happen when I tried dissolving the gold in piranha solution a year or so back.

[@Antonowskyfly]

You’re welcome. Well within range of the estimated yield will get you well past the porch door. A possible solution could be to use an electrical outlet plug-in timer to run the hot plate, of course adding another moving part goes against the grain of simplifying and streamlining. I have to believe the main concern was the live wire and not the state of the product, not to mention your wellbeing…that’s love! Thank you Ma’am and Sir! 👍👍🤟

[@empirefinds]

Awesome conclusion fantastic recovery thank you streets

[@JacobCanote]

LOVE THIS! You are such a killer chemist.

[@deplorable1-2]

Burnt your solution? Mr. White would not approve.

[@Mark_4_Now]

Since the Mrs was pissed about the burnt gold, i hope you played a trick on her and showed her the little piece of gold and said because of "your" daughter this was all of the gold you was able to recover...then show her the bar later after she chewed out the daughter(maybe even let the daughter in on the joke as well beforehand).

[@sreetips]

Oh, I wish I’d have thought of that. That would have been a good gag. But I have pulled back from raising her stress level since we’ve entered our “golden years.”

[@mcwolfbeast]

Most likely what happened is that part of the chloroauric acid crystallized out, and part decomposed to elemental gold and chlorine. Rehydrating and re-dissolving the elemental gold with H2O2 was exactly the right approach :)

[@scotthultin7769]

First 👍's up sreetips thank you for sharing 😊

[@glOckcOma]

Very happy to see you recover the gold with no losses. You never know, one of these accidents may lead to a discovery of quadrupling your yield of gold 😊

[@Vile_Entity_3545]

Well unless he had a nuclear reactor to transmute the element of gold into lead then he was never going to lose anything. Elements do not disappear into thin air.

[@scrapman502]

He never loses gold, it just gets left behind in his filters, poured out in his rinse jars and spilled onto tables. Ne never loses it! He Just temporarily misplaces it!

[@habracken8004]

I’m ready for a filter paper recovery/refining. I was telling someone earlier this week that I’m a sucker for anything you do involving fire. Lol. I’m a firebug.

[@DonnyHooterHoot]

You re-dissolved it! I would have never guessed! ; ; Great video!

[@sillybears4673]

Would be cool to see you use frozen msb in ice cubes cool off the solution aswell as precipitation out the gold

[@sreetips]

That would be a cool experiment.

[@Heymrk]

Good deal! I don't know a whole lot about gold refining, but know a bit about chemistry. I knew you'd be fine when I watched your video last night. It would be a pain in the butt to get it back and you'd probably lose a little to evaporation, but I knew you'd be able to recover it.

[@joek511]

I stopped at 4:28. I As I said in the other video, you only need to rehydrate it. , and you would have percentage of metalic gold. That's what the yellow is. Like any other metalic solution if the concentration gets to high the metal will come back out as metal. Gold is no exception. As the solution begind to evaporate it must drop out some of the metal. You have some of the finnest gold known to man sitting in the bottom

[@elipsorange]

Does it seem like using Hydrogen Peroxide is better than using Nitric Acid? To me, it seems like it's cost effective rather than from a purity standpoint. Just wanted to hear your opinion about it

[@gfhrtshergheghegewgewgew1730]

i think it's easier and cheaper for the amateur/home chemist to produce their own nitric acid than it is for them to produce their own 29% hydrogen peroxide, if you're talking strictly in terms of purchasing chemicals then hydrogen peroxide is cheaper yeah

[@sreetips]

It’s cheaper and actually cleaner because no nitric present that must first be remove before precipitation. But it’s not as fast as nitric.

[@Fourby]

Would you say this is your biggest mistake to date? I often wondered if you’d ever lost gold down to knocking over a beaker or some other accident? A great set of videos, thanks for all you do.

[@sreetips]

No, I broke beaker full of PGMs once during my stock pot one video series. I think it was part 8 of the 16 part series.

[@jalalhamdan1415]

Thanks away this is very simple way to get the gold precipitation well

[@stevelemley8446]

I think you can add aluminum and it turns red/ pink gold

[@azafreak]

Keeping a stash of dried chloroauric crystals is a nice stealthy method of storage. Great for when the G man comes knocking

The G man won’t know, unless you tell him.

[@pauljoneseyboy9615]

I have to admit, I have been checking every hour for this update! I have been worried sick!

[@NicholausFox-fo4xh]

Could try ice with little to no gas in the precipitation process. Bartenders use it for presentation. It might keep the cloudiness in solution down while stirring in the sodium bisulfate. It’s just air but it could keep things cleaner looking. Also might be a good video just for experimenting.

[@robertsemple1092]

I thought he’d use the hydrochloric acid to rehydrate as he does when he boils down the solution to eliminate excess nitric. Then drip in some nitric to create aqua regia but I assume the peroxide is less reactive.

[@sreetips]

Peroxide ensures no nitroso compounds.

[@shaneyork300]

Another question if the answer is yes, then hopefully it'll be a challenge for a future video! Can you take the dehydrated gold & melt it to a bar? Maybe make a video using a small amount to show us. Reason I asked is it looked like dropped gold.

[@sreetips]

Too risky. In that state it could vaporize and cause losses.

Probably be like trying to melt silver chloride. I know sodium chloride (table salt) will go molten and not burn.

yes sir i told you you have to make AR to recovery the burned Aucl2 AR best than hcl+h2o2 nice job

[@ahmeda8042]

Have you considered applying ammonia rinsing and boiling to the precipitated gold powder as an additional procedure? This might ensure the removal of platinum group metals and copper. I believe this could enhance the purity, potentially yielding a lighter brown color rather than a dark caramel hue.

[@sreetips]

Ammonia is not necessary and adds another step to an already lengthy process.

[@oculusangelicus8978]

You never burnt the solution. It was dark, yes, but burnt? No. but it went right back into solution and like I said before it could easily be a stealth way to store any gold you don't want people to steal, knowing that it will easily go back into solution and then can be precipitated out with some SMB. And you're absolutely right, it wouldn't be detected by metal detectors either, so you could lock it int with something else to make it even more hidden, say, with a bunch of iron oxide if it doesn't react, because they are almost the same color!

[@MadScientist267]

It had been changed by the heat. If it were simply dried out it would have all come back without the H2O2 or heat.

[@MikrySoft]

Chloroauric acid decomposes to gold (III) chloride (gold trichloride) at 120 degrees C, then to gold (I) chloride at 160*C and to metallic gold at 210*C. Both chloroauric acid and gold (III) chloride are water-soluble (350g/100ml and 68g/100ml respectively), gold (I) chloride is not water soluble to any meaningful degree.
