I love watching u refine gold and silver because you r the biggest and best channel to do refining, we all learn so much from watching u because it's amazing to watch.
Thank you for having taught me enough so far that I know what inquartation is for. It seems at first counter-productive until you understand the next chemical steps.
My favorite part is when you first start melting in the dish. That first layer of crust as it melts looks awesome and beautiful all at the same time! Thanks again for continuing your videos, Mr Sreetip!
Tell me why everytime i see you post a new video i zone out and watch it like a little kid watching cartoons. Ive got a collection of scrap gold and boxes full of silver coins/cups/flatware of all types.i hope to learn enough from your videos to figure out how yo rifine my heavy metals to its purest form...and then...well i guess start collecting and do it all over again lol
Coins are almost always better as the coin than as scrap. They will follow there metal content without refinnning, often beating it for the collector value.
Been out of the Navy since '97. Never got the oil lab experience I needed to help with exams. Been a long time since I've heard/said/logged "clear and bright"
I used to milk cows when I was a kid at my father's dairy back in Mexico, everyday when I get to the farm I would put my dad's old shirts over my school uniform to start milking cows kind of like a coveralls for kids and the one that last me the longest was green with white squares on it!! My mom being American brought here when I 16. I didn't even know what gold was back then..anyway, I grew up. And learned about gold. you are the G.O.A.T. as we call them in sports, that precipitation was absolutely the greatest thank you!!
I've been really getting itno your videos lately, and nothing quite as informative on youtube for this stuff. Well done to you. I would love to see a breakdown of what it costs you to break down this scrap to pure gold and silver. Mabe, including how you got the scrap jewelery, cost of it, cost of chemicals, and what it's worth after refining. I think that is something a lot of us would find great interest in. It would definitely be a great part 2 to this video
Sounds like a lot of work. I don’t really track expenses for each batch. And when it’s done, i think it would be foolish to convert the highly valuable gold back into paper dollars that are going down. I’d guess a refining of this size would cost less than a hundred bucks. Not counting the metals.
Oh man. Looooong day at work, needed some relaxation. Nothing better than some fresh sreetips to soothe the soul. I studied a bit of chemistry back in the day and I loved nothing more than practical time in the lab. It was always so rewarding to watch what you know in theory actually happen. I know it’s cumbersome to record and to maintain some degree of safety, but your vids really scratch that old chemistry lab itch for me! We really appreciate you sharing this. Thank you sir!
I think..That first reaction was so great, because you cleaned everything so well. You said you went overboard with the nitric boils/cleaning. That first SMB reaction says maybe, you didn't.😁
I've been working my a$$ off and missed your production...Im sitting here with some Pistachios (Chili) and a cold beer after work, and need to say I really appreciate the new lighting arrangement you used to show how cool it looks when you precipitate your gold into solution. And really cool when you added the SMB and it looked like angel hair 😇 as you precipitated your gold out of solution. That was awesome 👌 Thank you for a great video, as always 😬
Adding the SMB was so pretty! Allowing the Brownian motion and convection currents in the vessel mix the chemicals. Looks like something from a sci fi movie! Like golden clouds floating around. Stunning! You can use 2 filter papers at once if you think the paper might break. Can use the same size twice or use a finer one and a more coarse one, with the coarse one on top of the finer one. EG use a 40 on top and a 44 underneath. Have you ever swept the floor, the inside of your hood etc and seen what may have deposited on the surfaces etc from splashes/fumes? Maybe worth checking the filter of your hood to see what precious metals may have evaporated in gaseous form? Have you ever tried to extract gold from sand/soil/tailings from maybe a gold prospector? Could be fun!
Great video , I’m going to keep stockpiling all gold containing components of everything I strip down until I have around 50kg then get it refined for the gold
So amazing, when you do that first aqua regia and you don’t get the “forbidden orange juice” after adding the ice, but instead just get more dilute chloroauric acid.
I agree with all the comments it never gets old. You are the master. Everything is so seamless and precise. Ive done four refines now and two of them i boiled over lol questions for you ..Is it still fun for you? What is you favorite part? How long have you been into noble metals? Without getting too personal and if you care to share what did you do before this is it full time for you? Sorry for all the questions out of the channels i follow you are the only one i am curious to know..
This was begun as my hobby. Then I posted a short video for kicks. A year later I seen my video on a search engine. Logged in to my RUclips and the video had 92k views and 1600 subscribers. But lately, it’s become more of a chore to create new content. Someone once said that if you turn your hobby into your work, then it becomes just that, work. My favorite part is precipitation - that never gets old.
@sreetips the chore part being recording itself or just trying to come up with different ways and techniques? Because imo it's never gets old you could do the same thing over and over again. Thankyou for your replies.
One time when you are melting the gold powder down you should stop half way. It always looks like a cool sculpture. If it remained as 1 piece I am sure it would look epic!
Sreetips thanks for all the knowledge and entertainment that you have given us over the years. I have one question! What is the average per ounce that it costs to refine gold? Thank you so much if you can answer this and feel free to do so privately.
You're work kicks ass man! Thank you :) Re: Land of Chem, Palace of the Goldsmith site visit Ep.? This off Nile structure has seven chambers with massive door jambs, chemical staining, and vent holes at the top. Sounds more like a Palace of the Gold Refiner to me.
Septic means sevenfold, septic sludge looks like refined gold sludge, seven rings to bind them in a cycle of heavy metal extraction and refinement. Mordor was real.
that is worth £9254.35p in the uk today mr sreetips nice one as always good cook twice over here a question sorry if sounds stupid ok you wash the gold twice to be more pure so if you where to do it a 100 times over what would be the result oh ye gold master sorry for my ignorance ????
So if the gold is .999 fine after the silver and base metals are pulled out why keep refining it if you can alrea get top dollar from the buyer ? Unless it's just for the video
@@movietime111 sometimes people try to use soft solder to do repairs. Soft solder contains tin and lead. The only way I know to remove the lead is to add a few drops of sulfuric acid before filtering. I add sulfuric even if I don’t suspect the presence of lead. It’s cheap and doesn’t hurt the process at all. I understand that adding sulfamic acid also works because it turns into sulfuric acid upon adding to the gold solution. Lead, even in trace amounts, ruins the malleability and ductility of the gold.
Love your setup. Been watching for years and just decided a month ago to put it to practice myself. Just still confused over filter papers. Seems everyone has a preferred paper but can't get an answer to what is best for each situation. Was wondering what you recommend. And also any suggestions on Nitric, Hydrochloric, and sulfuric sources best bang for the buck??
I think we are about to find out how much nitric it takes to dissolve the striped shirt! I thought it was a goner for a while there. That Walmart time lapse watch is still going strong too. Not as shiny though. 😊
If you were either get a melt dish with holes under the lip or drill say four holes ( you could determine the size of the pellets of metal by altering the hole size ) you might get a finer product to add to the acid .
I've been watching since around 2013-2014, so you could say I'm a long time fan! What part of the navy were you in? I'm currently enlisted as a nuclear machinist mate
Awesome vid!!!! The sulfuric acid used, do you have an over the counter brand you go with or is this unused (new) battery acid? Tertiarily (or) do you purify and concentrate the sulfuric acid via distillation or boil off with hydrogen peroxide (Caro’s Acid) process? Currently I purchase a 98% product that is clear and i believe is the azeotrope and only H2SO4 and diH2O. Staying away from purple drain cleaners and buffered Acids. Amazing work! Thanks!!
Wow mr Sreetips this is an awesome ✨️goldbar ....you proces of doing this is great....miss Sreetips is going to be very happy😂🎉greetings from the Netherlands 🇳🇱✨️👍
Would putting the sterling through a ultrasonic jewelry cleaner work as well as heating it to get rid of the oils/gunk /etc., or do you really need to heat it up to thoroughly clean it?
Ultrasonic would be helpful, but not necessary. One of my mentors had a saying, “the three most important tasks when dealing with scrap gold are; incineration, incineration, and incineration.
I love your channel sir... I wanted to ask you how did you get started in chemistry I noticed you were Navy. Thank you for your Service I'm new to the channel but you have a regular subscriber now!!
Excellent, thank you. I used to just resell all the scrap gold. Then I began to wonder what they did with it after buying the gold from me. The rest is history.
Have you noticed any of the gold on your omega watch being removed from your years of refining? Doesn’t seem likely given your example with your wedding ring but I’m just curious. You rock Sreetips!
Is it possible that the gold which came out of the solution at 23:50 was especially pure? Whether it is or it isn't, just a hair under $12k for the bar and the baby.
Awesome video as usual. I've seen you do this process many times, but still fascinated by it. I'm curious of you had a background in chemistry before your refining career?
@sreetips At 35:53 I see you still have pieces of gold powder on left dish and some on the right dish. Also a bit of gold powder on the edge of melt dish. That bit will be dropped on the floor at 36:06. You are very careful with all that rinses and boils to not loose a drop of gold solution but here quite a lot of material is potentially wasted. On your melting table and gold bar jig I can see many small round droplets of pure gold and possibly silver. Maybe it is time to collect and process those tiny bits 🙂
Bom dia, preciso de mais uma informação. Qual a solução que voce utiliza para saber se ainda tem ouro na solução decantada? É uma solução estanhosa? Como encontro esse produto?
I use stannous chloride testing solution to test the decanted solution for the presence of gold. There shouldn’t be any tin in the waste solution. I bought the stannous chloride crystals to make the stannous testing solution on eBay.
The inquarted Au stuck together because it was still 1000 deg + when it hit the water. It couldn’t dump the heat of fusion fast enough because there was too much hot mass in that volume. You poured too fast. There isn’t enough cooling you could do, in that small volume, to prevent it. No harm. No foul. Fun watch. Good work
I don’t buy scrap gold on eBay. We buy at local sales. On Friday Mrs sreetips bought an 18k ruby bracelet 53 grams for thirty bucks. It wasn’t marked. But she could tell it was gold. It was in with the costume jewelry at the sale. On Saturday she bought a 14k solid gold watch for ten bucks. That’s about fifteen hundred worth of gold for forty bucks. 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 the metals will be long gone. They had a sterling flatware set for eight hundred but she passed on it. We’ve got too much silver!
That first SMB round was like watching storms on Jupiter, or the most expensive coffee ever poured. But I've got to say, Sir, that time-lapse of the reduction after the second aqua regia round gave me some instant anxiety 😂 Not that you could actually damage the gold, but seeing it reduce down to tar like that made me think the video was going south from there!
@sreetips ok then, I noticed the color change of the gold chloride from yellow to orange tint more you refine from 99 to 999 to 9999 fines, But theirs a time limit on heat making the syrup color means the nitric evaporated out. Ok Thanks Sreetips ❤️
There probably wasn’t much nitric to begin with. I was doing something else and wasn’t paying attention. All the nitric was gone well before it turned dark.
@sreetips It happens to me , my mind gets me to thinking about other projects or things that need attention, then I forget. I guess we all need to set alarms ⏰️ Thanks for explaining what occurred. Have Great Weekend Sreetips ❤️

I can't think of a more beautiful colour than gold dissolved in Aqua Regia! The more orange the better.
It’s a darker shade when it’s hot. Then it turns lighter orange as it cools.
Thank you for the 1064°C warm welcome. Perfect timing for chowtertainment! Thank you Sir!👍👍🤟
I love watching your videos they are so therapeutic for some reason and informative thank you for sharing your skill and hard work with us all

That looked like a lot of body oil burning off the gold jewelry when you hit it with the torch. Kind of funky to think there is that much stuff on it.
Love watching the gold and silver getting mixed together
That was a beautiful thing, watching that crucible with the gold mountain turning into gold lava made me cry.
There was a small fleck on the side of his dish that flew away. That almost made me cry
@troutmaster3 I’ll get it when I sweep the area.

I like the sodium light filter if that is what you used while doing the melt and pour.
I see you have made some upgrades, and I like them new jars with locking lids very nice, and the gold looks amazing too.

Such a beautiful bar of gold and that little bead sure is pretty
Nice single filtration results. Stop heating when the liquid turns purple, or dark red to purple.❤
Something about watching the SMB turn into gold powder. It's psychedelically mesmerizing.
That was sure pretty when you were melting it down in a clean melt dish. That would be why we like to see it. Thanks for the video sir.

I’d guess a typical refining cost for one ounce of gold is about fifty bucks, not counting the metal.
great looking bar nice bonus bead

Nice work and beautiful result..❤
Thank you! 😊
Damn I think I’ll set up an eBay account. Your stuff seems to sell for at least twice as much as it’s worth. Well done sir.
That’s because it’s made of GOLD. And the spot price is less than half what it should be.
I wonder if using a tall temperature resistant measuring cup would work better for drying and transfering the gold to the melt dish?
You're work kicks ass man! Thank you :)
Re: Land of Chem, Palace of the Goldsmith site visit Ep.? This off Nile structure has seven chambers with massive door jambs, chemical staining, and vent holes at the top.

Septic means sevenfold, septic sludge looks like refined gold sludge, seven rings to bind them in a cycle of heavy metal extraction and refinement. Mordor was real.
I wonder who was operating the reactors @ 14 ka? The same controlling gold et al production today?
that is worth £9254.35p in the uk today mr sreetips nice one as always good cook twice over here a question sorry if sounds stupid ok you wash the gold twice to be more pure so if you where to do it a 100 times over what would be the result oh ye gold master sorry for my ignorance ????
Do you think it would have a different effect if you dissolved the SMB (in some liquid) before adding it??
Possibly
So if the gold is .999 fine after the silver and base metals are pulled out why keep refining it if you can alrea get top dollar from the buyer ? Unless it's just for the video
I think is more something like .98-.995.
It's close to .999, but he can't call it that
The first time you did the smb it reminded me of the clouds over Jupiter.
That’s exactly what I was thinking.
Is there another way to remove any lead present without sulphuric. Is it necessary to use sulphuric when refining karat gold? Thank you
None that I know of.
@sreetips is the sulphuric necessary with karate gold?

I use Rooto Professional Drain Opener from Ace Hardware. It’s about twenty five bucks per gallon. The data sheet says it’s 93%
Best precipitation footage ever!

How much more pure is this final refined that if you had just ended after initial nitric and hydrochloric rinses
990 to 995 after the nitric boils.
Is it possible that the gold which came out of the solution at 23:50 was especially pure? Whether it is or it isn't, just a hair under $12k for the bar and the baby.
how often do you replace your crucibles, this one seems to be fairly new...... ie how many gold melts do you usually get per crucible ?
About ten or so
Awesome video as usual. I've seen you do this process many times, but still fascinated by it. I'm curious of you had a background in chemistry before your refining career?
No, my chemistry knowledge is all self taught. I have no formal chemistry training. Just an intense desire to succeed.

What are the orange fumes that come off of the inquarted gold in the process of taking out the silver ??? is that silver oxide?
No, it’s nitrogen dioxide.
The inquarted Au stuck together because it was still 1000 deg + when it hit the water. It couldn’t dump the heat of fusion fast enough because there was too much hot mass in that volume.
You poured too fast.
There isn’t enough cooling you could do, in that small volume, to prevent it.
No harm. No foul.
Fun watch. Good work
Sorry if this is a stupid question, but why add silver to the gold in the first step if you are just going to use acid to remove it in the next step?
So the acid can penetrate
Can you do a video on buying scrap gold from eBay from a vendor such scrapgold, to see how much gold is actually in there or is it a scam....
I don’t buy scrap gold on eBay. We buy at local sales. On Friday Mrs sreetips bought an 18k ruby bracelet 53 grams for thirty bucks. It wasn’t marked. But she could tell it was gold. It was in with the costume jewelry at the sale. On Saturday she bought a 14k solid gold watch for ten bucks. That’s about fifteen hundred worth of gold for forty bucks. 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 the metals will be long gone. They had a sterling flatware set for eight hundred but she passed on it. We’ve got too much silver!
Love yr stuff. Thank you
Kinda wonder if that bug became a Ever Lasting thought full Haze!!!; )😂
Great vid as always. Have you ever experimented with inquarting with copper instead of silver?
He’s done that at least once. Go through his video library
Yes, videos posted.
That first SMB round was like watching storms on Jupiter, or the most expensive coffee ever poured. But I've got to say, Sir, that time-lapse of the reduction after the second aqua regia round gave me some instant anxiety 😂 Not that you could actually damage the gold, but seeing it reduce down to tar like that made me think the video was going south from there!
Great video once again sir.
Awesome stuff my friend, your videos are great sreetips 👍
Thank you
16:50 Best precipitation EVER !
Turning the gold chloride to a syrup , what does that do ? Does it condense the gold ions together ? Thxs Sreetips ❤
I evaporate it down to drive off excess nitric. But let it evaporate too long so that some of the gold came out of solution.
@sreetips ok then, I noticed the color change of the gold chloride from yellow to orange tint more you refine from 99 to 999 to 9999 fines,
But theirs a time limit on heat making the syrup color means the nitric evaporated out. Ok Thanks Sreetips ❤️
There probably wasn’t much nitric to begin with. I was doing something else and wasn’t paying attention. All the nitric was gone well before it turned dark.
@sreetips It happens to me , my mind gets me to thinking about other projects or things that need attention, then I forget. I guess we all need to set alarms ⏰️ Thanks for explaining what occurred. Have Great Weekend Sreetips ❤️
Seriously, beautiful
Sir , Are you using concentrated or dilute sulphuric acid
The safety data sheet say 93% sulfuric acid.
That was a good pour.
Was all that jewelry in the beginning all pure gold? Or was any of it gold plated?
It was all karat gold. No plated pieces were in there. Gold plated won’t work with this process.
@@sreetips Oh ok, thanks!
Why does the gold solution look darker, almost reddish orange when hot, and lighter, more yellow after cooling, even before diluting with ice?
I don’t know, but that happens just about every time.
