You are welcome. A great demonstration. A “cleaner” precipitation here, there was very little accumulation on the delivery tube and it was visually stunning too. Thank you Sir!👍👍🤟

[@wayneneher6362]

I KNEW you were going to do SO2 for some reason, Chief. I'm with you, it does a very nice job of dropping the gold. Not having to rinse chemicals is a good thing.

[@Dr_b_]

Can't wait to see the bar/pours now, bet that Au is exceptionally pure, also the large glassware is impressive.

[@cspiff]

That 10-liter beaker is just comically large. It cracked me up.

[@apveening]

No problem, as long as that beaker doesn't crack ;)

[@andrewrossi7164]

Awesome sreetips, you sounded so happy when you saw the gold coming out of solution, can't wait to see the finished bar 👍

[@johnizitchiforalongtime]

That experiment looked like it wasn't working, but the time lapse proved you were spot on, where you got the information to do this for a pure form of gold is astounding. Great Job.

[@curtisdkruger]

It was almost shimmering when it first started to drop out of solution - pretty cool

[@darrellsmith5395]

[@xxxULTRANOVAxxx]

I really enjoy watching these videos, its very meditative for me.

[@matthewtracy8744]

I don't know which I like better, the straight SMB into the liquid gold, or the SO2 delivery system and the "flash" before it drops. It was extremely cool at this level! That's a LOT of gold!

[@D_A86]

Despite watching you do this process a few times now, i always think, "How do you know when it's done?" Then you pull out the stanus test, and im like, oh yeah 🤣🤣🤣

[@Sanzus2]

Got a soup pot now! Seems like not that long ago a 4oz bar nearly vexxed you! Flash over was hell of a show, one of the best demos ever!

[@zube6996]

That was awesome. For awhile there I thought that it wasn’t going to work and then boom, it just dropped out of solution. Absolutely amazing!!! Thanks for sharing.

[@johnson2207]

Did the iron come from a clasp or spring amongst the jewelry that got inquarted?

[@sreetips]

Possibly

[@cam_von147]

I think it came from the ice cubes, that's if they weren't frozen distilled water

[@mrimmortal1579]

Sometimes I wonder, Sreetips, if you just do this gig in order to show off your awesome laboratory glass collection! 😂 Seriously though… when you pulled up that 10 liter beaker I literally said “Holy crap!” right out loud! It looks like you used *WAY* less SMB for this precipitation than you would have by adding it straight to the gold solution. Plus now you don’t have to wash off the excess chemicals! I’d be tempted to do the SO2 gas precipitations more often. Also, were you able to use less nitric acid than expected just by starting out with a larger than normal amount of hydrochloric? That sounds like something that would be worth exploring further. Hope you have a good night, Chief. See you for part 3!

[@sreetips]

I ordered the ten liter beaker on Monday, and it arrived Thursday just in time for me to make this video. SO2 gas is a very clean precipitation. I like it too.

[@ChrisLennex-cm8vr]

The work you do is excellent. It almost reminds me of the phosphorus test I had to do when I became a bulk sorter. When I have the room and tools, I should do this. Keep inspiring others.👌👌👌

[@wadebert4458]

You are a true Master! That was incredible, Gunny! I started pouring off my solution, when using Silver to enquart, into several 3,000 ml beakers and adding HCL. The Silver cloriode forms and I go from there, recovering the Silver cloriode, converting it with NaOh and sugar, before running it through the Silver Cell. I noticed something interesting in my current boil I just started. The first few times, the pour off was mostly Copper Nitrate. Only after the third boil did I start to get Silver cloriode to start forming. Interesting. It's a larger amount than I normally do, so I suppose that there would be Copper in the mix. Or, quite possibly, I got into some Silver plate. Either way. I save the Copper as well and it doesn't seem to effect the process adversely. I know that Copper isn't a PM. It does have value though and the price for clean Copper is climbing. Like I said, I'm Scotch.

[@sreetips]

I buy clean copper for refining at local sales. It’s cheap and plentiful.

Can you readily buy Sulfur dioxide gas in cylinders? Would it be handy to have a tank of this to do all your gold precipitations instead using and buying smb?

Oh yes, it would.

[@alasdairblackmore2592]

So doing the 6 hydracloric asid boils get the junk metals out faster? Befor you get in the aquregia boil. Then the cool off with distiled water. Then the MSB drop and check all has dropped. Then a final rinse with HCA boil. There is still the oops of iron, or the platinum famiy on occasion. ROUGH! I love watching this channel for just learing somthing new eash time.

[@lutomson3496]

his process is interesting ive gone through the gold mines here in Nevada they use cyanide to leach out the last amount of gold in the tailings and remains of the refining process those fields go on for years...

[@menlikegods363]

The old-timey miners used to say gold rides an iron horse. Apparently, that's even true in the refining process. Fascinating stuff.

[@debcamp2359]

❤ the experiments! Especially the story. SO2 gas looks very efficient?

[@sreetips]

SO2 gas is a very clean precipitation.

[@Chris-ch5nb]

10L beaker! Wooo! Next time you rebuild that fume hood would it be prudent to install some sort of shower pan/catch basin under it for whenever the inevitable happens?

[@sreetips]

I used to have a plastic pan in there but it got deformed over the years.

[@pogue6327]

Very cool to watch

[@OneOfDisease]

This gas method seems so much more pure then just dumping SMB into the mixture.

[@sreetips]

It is. Gas is by far the better method

[@Victor-dk1ct]

WOW!! Just wow!!! That is amazing! Did you drive off the excess Nitric (evap) before the SO2 precip or let it (precip re-dissolve loop) until all the nitric was used up? I did not or could not see any red fumes being generated in the beginning of the SO2 precip to confirm. Thanks again, amazing videos can't wait till next one!

[@sreetips]

I used incremental nitric dosing; adding just the right amount of nitric to just dissolve the gold. If done correctly there’s no need to drive off excess nitric because there won’t be any to drive off.

[@JoSeeFuss]

Very cool. Really believe that you should use SO2 Everytime for the final precipitation. Just get a much cleaner result, cant wait to see the bar or coin.

[@sreetips]

It is very clean. The downside is it produces a lot more waste that must be treated.

[@ninailsgimp]

BREAKING NEWS: A youtuber turned 6oz of gold into brass in an experiment gone awry. I'm kidding, haha I always enjoy your videos. I wish my mind would understand the chemistry better, but I've also never really researched it much. Keep the videos coming, though!

[@kevinakers9971]

Beautiful reaction! Until you turned up the flow, i thought you might need another supply of gas because of the volume. Can't wait for the next chapter. As always, I appreciate the knowledge.

[@jimwednt1229]

It's interesting how once the gold is clean it separates from the water immediately. I wonder why the gold clumps together so well when it's clean.

[@scorpionfpv6412]

I do wonder if the depth of the delivery tube and the volume above have more of an impact than how dilute it is, It would be good to have some different sized beaker/tube with samples of the same solution (same volume of liquid) and then a T off from the gas generator so we have 2 delivery tubes you could then see which solution turns quicker (a race where precipitation counts) the theory being the gas has more time to dissolve

[@deboshadow]

It's beautiful to watch a safe chemical change like that

[@nikolajwinther5955]

Would love it if you spent a bit more time with the scrap karat gold, like dwelled upon the 5 or 10 most interesting or largest items.

[@theallseeingmaster]

It looked like a storm of gold in that beaker.

[@richardwarnock2789]

It's Deffinatly got the Pot Belly Bonaza Feel to that Beaker!!; )

[@deanfranklin6870]

Using the SMB gas rather than just adding the SMB directly into the gold syrup has to be the cleanest method of recovering the gold from the "syrup". Any way you look at it it's an amazing reaction to watch. Thanks

[@deanfranklin6870]

Have you considered making a cooling system for modifying the temperature during reactions? A small container with very cold salt water that is pumped into a coil inside of the beakers? If you're interested I'd be happy to explain that more in depth. Thanks for showing the series. Outstanding as always

[@Sausketo]

I wonder if they make glass fish tank bubblers, i imagine this would work faster with a bunch of smaller bubbles. Same amount of gas but with much more surface area

[@sreetips]

The delivery tube must be at least 1.4 inch (6.35mm) or else the gold will form and clog it up.

[@CothranMike]

@@sreetips yes, too small and the orifice will get clotted gold at these pressures (just above ambient pressure 1.01). If using gas flow at higher pressures like 1.5 bar be prepared for more splash and movement of the delivery tube but if used with a manifold feeding three or more tubes or orifices this will be less of a problem. Great beakers, it's alive!

[@Ferd414]

Neat precip. What gets left behind in the solution when you precip with SO2? Is "Sulfur Chlori(d/t)e" a thing?

[@sreetips]

Nothing that I know of. That’s why the gas precipitation is so clean. When we dump the SMB straight in then there’s a bunch of salt. But there’s nothing but clean gold left after the gas precip.

[@judgetk8327]

That was neat trick of chemistry but I was curious of how much acid was evaporated to reach no gold content?

[@sreetips]

I don’t know how much acid

[@evanhernandez1450]

The process is amazing and the proof is in the pudding, but what is your profit vs overhead for all the chemicals, supplies, etc...?

[@sreetips]

The gold is my profit. I’ve converted paper dollars, that are declining in value and purchasing power (the proof is in the grocery store cost of food) into highly valuable GOLD. This is my hobby, so I don’t track expenses for each batch.

[@jasonodonnell5177]

[@darthex0]

Tipping point😮👍

[@davidporter9131]

Bearing in mind the cost of the scrap gold, acids, gasses and electricity. But excluding the equipment costs. What is your profit margin and where do do you sell your refined gold?

[@sreetips]

We gain profit when we buy. I’ve never calculated it from a specific batch because it’s highly variable. For example, my wife traded four hundred bucks for about three thousand in gold the other day. Last Friday, I went to a sale with her and we bought (traded paper dollars for) $2800 worth of scrap gold. We picked every piece of karat gold all bagged in small baggies with a price marked on them. When we tallied it up came to $1900. Then my wife asked the seller if they could do any better (in my mind I’m saying no, don’t, this is an excellent bargain). To my astonishment they knocked $300 off so our total trade was for $1600 worth of paper dollars given to them for $2800 worth of highly valuable gold. We traded paper, that’s declining, for gold, that’s rising. People are clueless about the value and importance of owning GOLD. They think, incorrectly, that paper dollars are more valuable than gold!

[@carlherrnstein9544]

It's like watching a storm front blow in.

[@jamyesmith8205]

Need to find a defuser for that bubbler

[@sreetips]

Can’t use a diffuser, the delivery will quickly get clogged up with gold. 1/4 inch (6.35mm) opening at the end of the delivery tube is what the book calls for.

[@clintongriffin2077]

The SmB gas is it combined inside the liquid? Or does it create an Ozone above the liquid and eventually the PPM in the air cause the desired reaction?

[@sreetips]

The gas reacts with the liquid and precipitates the pure gold.

[@gmc9753]

The gas produced is sulfur dioxide, which is a reducing agent. It reduces the gold ions down to elemental gold.

[@navrangstudio8273]

Dear Sir after adding SMB in aqua reja is it better to keep the beaker open or close the beaker from the top.

[@sreetips]

It’s always better to cover the beaker to prevent gold from ejecting out, and to keep junk from falling in.

[@theccieguy]

Do you have a blog about your work here?

[@sreetips]

Just my KZbin videos. Refining is my hobby. I only work on stuff that my wife and I find at local sales.

[@greenmonstah8753]

How do you decide between boiling sponge in HCl or Nitric? Does one dissolve specific metals out of solution better then the other?

[@sreetips]

I use nitric during the recovery to remove silver and base metals. I use hydrochloric to boil the pure gold after it’s been precipitated during the refining phase to remove dissolved metals from the gold powder. Recovery and refining are two totally different processes. HCl does a much better job of removing dissolved metals than plain water does.

[@gfhrtshergheghegewgewgew1730]

that's a big beaker

[@denverd2007]

difference between precipitating directly with SO2 gas and precipitating with Sodium MetaBiSufite? does the process with sodium metaBiSulfite actually create SO2 gas almost instantaneously that then drops the gold?

[@sreetips]

Yes, SMB reacts with the acid and releases SO2. But there are by-products, salts that are in the gold from adding the SMB directly. The gas is much cleaner and introduces no salts.

[@jbyng7714]

I wonder which method is better for precipitating Au? bubbling SO2 gas or adding SMB crystals?

[@sreetips]

Bubbling SO2 gas is much cleaner.

[@justinbags1]
