Between the gold weight and the PGM weight it's almost exactly the weight of the incinerated materials you started with. That's an impressive win in my book. It's such a good feeling knowing nothing goes down the drain as wasted precious metals in Sreetips shop.
I don’t know why, but I enjoy these stock pot, filter paper, and gold refining waste solution videos more than any others. Fascinating to see valuables oulled from “waste” .
I’m happy you used to take the refining further in previous stock pot videos. I’m also relieved that you no longer torture yourself with refining PGM’s any further. That crap is just too dangerous.
Great Video Sreetips. Totally answers my question from yesterday. I didn’t realize the P metal’s stayed in solution when adding stump out. I just had to be patient and wait for the next video. Lol.
Morning Gunny! Incredible success! You make it look so easy! Maybe in another 10 years, I'll gain a modicum of your experience! I love these AWESOME videos! I keep them running as I try to emulate them! This is real Gold! Have a productive weekend! Biggest Fan! Wade
It's so amazing to see how the acid in the solution just about evaporates the zinc . 😮 I'm in awe every time I watch a video of yours on this subject matter . So fascinating to watch , listen , and learn from you .
That action is mostly the Zn reacting with the acid. It’d be a lot less flashy if S reduced the pH to about 7, then added powdered Zn. You’d get the same black cement Au, just using a lot less Zn.
Hello sir, I just recovered another 3,7 g of quite pure gold from about 240 g of goldplated pins using only HCl, peroxide (incremental addition), bubler (for a week) and cupeling foils with bismuth. I am going to repurify it by HCl, peroxide and SMB (or ascobic, or oxalic, not sure yet). Anyway, I will use my jeweller rolling mill to make very thin foil. Quartering 98+% gold is a bit overkill. I will test quartering with carat gold scrap later. Thank you for inspiring me to actualy do the recovery, holding gold from scrap is good feeling...
If he had that much Rh in this waste stream, this’d be a whole different video. I’m thinking it’s some sort of Na salt crystal from a supersaturated salt solution
I presume the stock pot gold had previously been inquarted with silver during the initial refining processes. 👈👶👍 That was quite a significant quantity of AU⚖️PGM's - fantastic!
@@sreetips That is was! I was expecting higher yields since the stock pot is so big, but this is testament to your refining efficiency. About 40 pounds of solution only had 14 grams of gold.
Rinse with distilled water. Scrub with alconox (glassware cleaner) and tap water. Tap water rinse, followed with distilled water rinse. Then air dry in the dishwasher rack. Since most of the solutions that l work with are acidic, there’s hardly any stubborn residue to have to deal with.
Awesome video as always, Sreetips! Still would love to see all of that cemented copper in your angle iron buckets, turn back and purified into a copper bar! I know that's not in your best time and financial interest but it sure would be satisfying!
Honestly, I'm just waiting to see it all get melted down into fresh "sacrificial copper" for the stock pot & silver cementation buckets. Refining to pure copper would be surprisingly difficult (Co, Ni, Sn & Pb fall between Cu and Fe in the reactivity series, and so would also be cemented on the iron, with the Copper), but is entirely unnecessary when simply making fresh sacrificial pieces for the cementation buckets :-)
About $800 worth of precious metals Sreetips. Not bad for a weekend's worth of work. 😎I must admit I jumped back in my chair for a bit when I saw that zink reaction. That was a real attention getter lol
Your videos are always a fun exercise in chemical metallurgy. As much as I would've loved to see some shiny beads of Pt and Pd, kudos on knowing when it's time to set aside the black powder for later.
I remember your 1st stock pot series! I can't remember if it was in a stock pot series where you dropped or broke a beaker over cardboard & you had to recover the precious metals by burning up all the cardboard & paper towels? I think you should repost part of it so you can let these 220,000 extra followers know about this old video & possibly alot more. Also maybe it's late at night & none of this makes any sense! Lol😂😂
Great video. Thanks for sharing your refining with us. I have 2 note books of your methods at my little shop, I'm always looking for knowledge and additional methods for PM metal recovery and refining.
In this series I learned that the hydrochloride acid boils really helped clean things up. And to crush the incinerated material before hitting it with the dilute nitric boils.
Absolutely beautiful work and a super yield. Don't forget there was the initial insoluble PGM powders which didn't dissolve after boiling in aqua regia, which is probably more of that iridium (or more of the same stuff that was an issue last time!)
Would it have been "cleaner" to use SO2 gas to knock the gold out of solution, rather than the SMB, in order to not have as many other ions in solution? Or had you already decided against chasing the PGM refining before adding the SMB?
For some reason I was expecting 15 grams of pgm and only a few grams of gold. But it turned out the other way around. SO2 gas crossed my mind. And maybe I’ll do it with the next stock pot refine about a year from now. SO2 gas would have been cleaner.
@@sreetips I was just thinking as I watched it that if you had used the SO2, the PGMs would not have needed to be cemented out on Zn & then re-dissolved in aqua regia again, as the SO2 shouldn't foul the solution of PGM salts. However, once you said that you weren't going to refine the PGMs yet anywise, I guess that doesn't make a difference for now.
There’s a critical ratio: 15ml to 20ml per gram of pgm powder. In order to get the correct ratio I need to weigh the pgm black powder. In order to weigh it I must reduce the black pgm powder from the solution with zinc.
I think the relatively low quantity of gold in comparison to how much you refine is a testament to how good your processes are. I would guess your stock pots end up with far less than one percent of the gold.with you striving for continual improvement and always looking for ways to enhance your skillls your stock pots will go years before having enough material
wow stockpot #5 done in under 5 videos? looks like you have it under control! the first was like 15 videos lol. 2nd was the same. 3rd and 4th was better and now you got it down ;)
Was recovering only almost 14 g of gold worth the effort and money spent on acids? I mean it's about 900$ worth of gold. So does that cover all the costs and time spent? If you don't Include the money made from the video.
Kevin I am a opal cutter I work with primarily Australian opal your silver eBay parcel looked like it had a large white opal in it set in a old silver setting the old opal like that deserves a real look at and might fetch far more than the cost of the entire lot of silver is it possible to get a video of the stone front and back and it's weight the stone can be removed and repolished if it has a dull shine to it if that's the case rub water over the face and please send me a video. Thank you for your time
Hello, it looked like a man-made opal. I’ve seen real black opal. And this one didn’t look authentic. But if it was, then that’s ok. That means the buyer got an exceptional deal. Win-win. And those are the best kind!
Because zinc is much more reactive than copper and therefore it reacts much quicker. Plus, I went to lengths to get the copper out of there prior to processing it.
It would be neat to see a cost breakdown of the different materials used for each processing step to see the real worth that is being made from the button. I'm starting to get mad at myself for not getting a chemistry degree in college instead since this looks fun if you know what you are doing.
The funny thing is that I’m a chemist and have an MBA and I can’t wrap my mind around the costs and the output value. The fixed costs are easy enough to identify. Just count up the equipment he uses. The chemical cost can be approached, but it’s dependent on the quality of the Au and Ag inputs. 8k Au will be more expensive to work up than 18k Au. The biggest unknown value is the price of his starting material. None of that jewelry is cheap. Any accounting would require the accountant to ID the value of each input as it goes into the inquartation pile. It’d be fun to know, but a lot of work to figure out.
My wife found an 18k bracelet for a dollar last weekend. Weighed 22 grams. That’s a thousand bucks worth of gold, for a buck. It’s out there. But it won’t just fall in your lap. You got to get up early and be there first. Or else all the gold will be long gone.
@@sreetipssome people mislabel it as costume jewelry? My wife and I buy gold and silver bracelets off Amazon for a buck or two but they say it’s 18k gold and 925 silver. They feel heavy but it can’t be worth much since it’s so cheap… I’d be interested in you buying some of that stuff and refining it to see if they’re undercutting their prices… I feel like they should be worth a lot more.
@@sreetips I scored a 1 and 3/4 pound sterling teapot ca 1890 from a yard sale this weekend. It was marked $10, but I talked them down to $5, because they insisted it was just plated. My biggest score ever. I’ve never seen gold like that. And not for looking either. It’s like you say. I really need to dial up the effort.
curious thought: if the solution is highly acidic when you put the zinc in, wouldn't the acid reaction prevent the cementation of the PGM? would it be better to neutralize the acidity first so the PGM will immediately cement out on the zinc?
So I've been working on treating my wastes and I've got a couple solutions that used to be copper chloride. I used some aluminum to drop the copper, how should I go about getting that solution safe for the drain?
Curious question, as i had never thought about it. As the zinc dissolves and PGMs cement out, does the PH of the solution increase, or stay the same. Hoping a chemistry buff could satisfy my curiosity
free HCl gets consumed; then the acidic salts of the precious metals get replaced by acidic salts of zinc. I know the consumption of free HCl will definitely raise the solution pH some, but I don't know enough to make a good guess on the salts' exchanges' effects on pH (besides to guess that it won't likely be very large)

With all of these stock pot videos now, we should have ourselves another platinum series by football season!
I was not expecting that fast and vigorous of a reaction when he dropped that pure zinc in that platinum solution. Wow. That was impressive. 🤯
There were PGMs trying to cement while the acid was trying to dissolve the zinc, together that goes fast.
Gooood evening from central Florida! Hope everyone has a great night!

I think those crystals are rhodium salt (RhCl3). After the melt there was a redish stain on the button that would be indicative of that.

Rhodium and iridium. I put it back into my stock pot to let it accumulate there.

I think it's not wise to burn those yellow filterpapers. pretty sure they contain Platinum Salts. They won't burn but spread as dust.
I really wanted to see the PGM refinement, dang it man, lol
I was hoping for about 15g of pgm and a few grams of gold. But it came out the other way around.
What happens if you just melt the back powder???
It'll make it more difficult to refine, powder is much quicker to dissolve.
It should form a nice shiny button of platinum and palladium.

seams, you have really stream lined your stock pot technique from pots past
Curious question, as i had never thought about it. As the zinc dissolves and PGMs cement out, does the PH of the solution increase, or stay the same. Hoping a chemistry buff could satisfy my curiosity
The acid gets consumed the reaction.
free HCl gets consumed; then the acidic salts of the precious metals get replaced by acidic salts of zinc.
I know the consumption of free HCl will definitely raise the solution pH some, but I don't know enough to make a good guess on the salts' exchanges' effects on pH (besides to guess that it won't likely be very large)
And anotger question. In this case when gold mixed with pgms in solution instead of mb to use ferro sulfate?
I prefer SMB because it’s a little faster and the iron is more difficult to rinse out.
That was pretty wild seeing the zinc getting ate up.
Probably a stupid question but I need to put enough copper in my stock pot so itll eat the excess nitric and have enough to cement the silver??
I keep silver out of my stock pot. Only gold refining waste goes in there.
Hey sreetips can you do some more PGM experiments and recovery and refining vids
It’s dangerous
always a great video!!
Great ending!
Won't copper do the trick for PGMs?
Yes, that’s why I keep copper in my stock pot.
@@sreetips Sorry I wasn't clear. Why use zinc instead of copper for PGMs?
Thx sreetips another great stockpot video!.

Question why y do not use zinc powder instead of zinc metal to preciptate pgm s from solution?
Zinc powder tends to create a very fine black powder that doesn’t settle well.
What was the weight on the Rhodium and Iridium you filtered out as insoluble material from the last part.
Not sure, I added back into my stock pot.
Does a SO2 gas gold precipitation grab platinum as well?
