Hey Sreetips, you will not get the steam explosion when pouring the molten metal into water if you bring the water to a boil ahead of time. The Japanese sword smiths have been making copper ingots onto canvas in hot water for centuries. It works well as long as the water remains above 185 degrees.
Watch his past videos as well! He is very knowledgeable about many processes. Take notes. They will definitely help in processing gold, silver, and other P.M.'s. (Precious Metals) Thank again Sreetips! Another great video!

Glad to see you finally got around to doing the hydrochloric boil, this step is so cheap, easy, and effective that it's standard operating procedure for me. You might also want to try boiling the gold after dropping it with SMB.
Sir you did loss 1.700 grams. This way you will get 9999 Purity but you loss sum grams of gold . 1.700 grams gold loss not a joke. It's have a valu of money. I will do this refine just adding double puer silver . with in one hour I will make it 9999 without any loss. 💯% recovery
Silver uses less Nitric than Copper for inquartation. This was a cool lesson though. It seems like rather than spending so much time trying to prep Sterling for the inquartation, just using pure Copper that can be obtained ready to go and seems like a cleaner quicker method. Very interesting, thank you.
This is the video I've been waiting for, inquartation of gold with copper! I've been watching the videos with silver inquartation, and I was wondering how you do it with copper. It's PFM, or "Pure Freaking Magic" ;-) or so it's seems. Merlin would be green with envy if he had watched your techniques, the glitter of gold is hard to resist, and you seemingly pulled it out thin air (or aqua regia). Fascinating to watch the precipitation of gold out of solution, and even more fascinating to see the glittering gold bars poured at the end. The little silver chloride accident was recovered from very nicely, and couple of quick filtrations and you were back to traffic!
Silver is the preferred metal for inquarting, because unlike copper, it takes only 1 equivalent of nitric acid to dissolve silver, but it takes 2 equivalents to dissolve copper. For most refiners, the biggest cost is the price of nitric acid. You’ll end up using twice as much if you inquart with copper rather than silver. Unless you can get dirt cheap copper or cheap nitric acid, the cost associated with silver and processing the silver chloride usually still makes it worth it. Here’s the equations btw. Ag + 2HNO3 = AgNO3 + NO2 + H2O Cu + 4HNO3 = Cu(NO3)2+ 2NO2+ 2H2O
@@sreetips thanks! Yeah, silver only ever forms +1 ions when dissolved so you only need one nitrate ion to form silver nitrate since the nitrate ion has a -1 charge. but copper always forms a +2 ion, meaning that you need two nitrates to balance it.
Very nice. That first little bar was absolute perfection. There is a lot of gold powder in that rinse water container... Maybe run it through a filter a few times and collect up that stuff? Probably a gram to 1.5 g of your "losses"...
The nitric acid with traces of gold and silver should have been used to dissolve the copper. Gold and silver would have been commented on it. After it's consumption the silver would also have dissolved.
Doesn’t matter if it’s a new or older video seems like I’m learning something each time…also when pouring the alloy into water would pouring it in boiling hot water maybe lessen the shock of the copper/alloy some so it’s not so violent?
Ever checked your siphon for metal particles? In India there are people washing gold in the sewer system because over time, little flakes break off from the jewelry people wear and accumulate in quantities large enough to form gold sand.
I just had a possibly weird question pop into my head. Is it possible to make the gold solution neutral and keep the gold in solution for extended periods of time?
I just watched a video where a guy used a half of a potato as a crucible. It actually worked. It would save you some money for sure. Cut a potato long ways and take a spoon full of the middle out. You can still add flux to get it loose.
Have thought about using aluminium to inquart gold with hydrochloric and then wash and hit it with nitric acid to remove the minor impurities that are left.
Do you happen to have a video of you refining gold, with copper and over the counter stuff. Also do you like cupeling, for refining. Or do you feel that it dont work the same. Love your videos.... thank you...

Hey Sreetips, I’ve been really getting hooked on your channel and I’ve been curious, do you need to be licensed to handle a lot of these chemicals? I’ve been talking to people about it and that’s what everyone has been saying anyhow.
@@puppetmaster4235 honestly im yet to come across anyone who hasn't been able to do refining legally, some people just assume that you have to have a licence for acids because they feel it should be that way. Anyway this is by no means solid legal advice lol i don't know the regs in cali so if I were you I'd give a chemical supply company near you a call so you get up to date advice 👍
At 26:00 you washed the gold with hydrochloric and then poured it off. The acid you poured off looked like it had gold in it, like some fine powder was washed out with the hydrochloric. Is that an accurate observation, as I was under the impression there really wasn't anything to speak of in the gold by that time?
A small quantity of gold gets poured off with the rinses into my waste containers. It’s allowed to settle out. Then I recover the gold powder from the waste containers.
@Sreetips I came across an interesting document about a particular Gold alloy with some very interesting properties. I have been watching your channel for a while and I know you are the 999s fine guy and you are also very professional when it comes to refinement itself. And this particular Alloy that i stumbled across some years ago may serve as some very interesting content since the alloy itself requires all 999 fine material. I think you would be very interested in taking a look at this gold alloy document and maybe performing some science experiments. Let me know what you think here and tell me where to send you this document i came across. It also has a couple of RUclips videos made by the creator of the alloy.
A special gold alloy that hardly anyone knows about??? WOW!!! Wait a minute, on 2nd thoughts this just seems like an attempt to get his private contact info. Why would you not have just added the link here for all to see?
That was freaking awesome.... why inquart with copper and not silver? Was there a potential for copper in the scrap jeweller mix? Maybe I missed the explanation in the series.. well bloody done👍👍
okay question, War nickels are 35% silver but have 35 % copper 9 % manganese in it, will this cause any problems, Proper ventilation and proper lab protocols are in place. thanks!
@@sreetips No you have no opinion on the 9% manganese? Could it cause metal fever or anything like that? I cant seem to find out much about the it? I am just being over cautious however, I cant be the only one out there that has a bunch of them and sure I can sell them on a auction site but I see it as a nice challenge extracting and making something beautiful out of them.
That’s interesting timing I am trying to refine a very small quantity and will boiling for an hour cause it to go into solution? I am still getting a slight hint of blue so I assume that there is still some copper in the gold. So I figured I will try to nitric it with small quantities for a few more times to see if it clears up. I don’t have much gold so don’t want to loose it in the nitric
Why not save that silver/gold nitric for your next procedure? Will you only be using copper in the future, I find that hard to believe as most commercial gold you buy is jewelry which already contains silver.
Guess you also could have added a bit of Hydrochloric acid to the Gold containing Nitric acid and filter out the SilverChloride then use it in a first refining stage to make AR and percipitate the Gold out.
Hello teacher. I know that maybe this is not the place for this, but it is possible to recover gold that was precipitated with excess smb? In the end there was a lot of white powder accented with a little gray powder which I think is gold, is there something I can do or I definitely lost my material? Thanks in advance for sharing your knowledge. I have learned a lot from your videos. Thank you very much!
SMB is soluble in hot (or cold) water. Add water, stir, let it settle completely (may take overnight), decant and repeat until all that’s left is the gold powder.
What book do you recommend for the amateur home refiner? Holy smokes the fume production from reaction #3 was scary looking and made me put fume hood on the top of my list of needs
@Sreetips I wanna know how you got started. Was it a hobby that turned into a business? Or was it something that you learned on the job and then turned into a business?
I remember watching a video that Cody made (Cody's Lab) and he was able to hammer the gold powder using no heat, into solid gold and made gold foil. It was super interesting, perhaps you could try something similar?
Couldn’t you just have added the nitric with gold in it to your temp gold refining waist container and then recovered the gold when you do the container? Same idea I guess. Just less steps I would think.
Adding nitric to the temp waste container would be a waste of nitric acid. Best to put it in the silver jar and add more sterling to consume the nitric and dissolve more sterling for refining.
I'm binge watching your video's at the moment & am fascinated you're such an interesting guy. Could you tell me if the solution of gold is much heavier than water?
Yes Tony. I did an experiment in my electrolytic gold refining video. In that experiment I weighed a bottle full of gold in solution and the then the bottle with the same volume of plain water. ruclips.net/video/zDfujDqEPMo/видео.html

Hello Sir, I have another question: If I have nitrous gases coming from the solution after Adding SMB, that means that I have excess nitric in the solution right? Does that mean that I have to just add more SMB? Should I wait over night to have the AR eat up the percipitated gold and add more SMB the next day to re-percipitate it? Should I put it back on the heat? Thank you for you help, much appreciated! Greetings from Germany
Red fumes = excess nitric. A little don’t hurt, add more SMB to remedy. A lot of excess nitric will cause much heat and fumes. Adding more SMB could cause a boil over - especially while stirring.
@@sreetips Thanks for the quick reply. It all worked out I guess, everything settled at the bottom. Solution is pretty clear now. There might still be slight impurities in the gold powder as it didn't settle as quickly as in your video. What are those impurities and how would you get them out? Clean the gold powder and redissolve in AR or do the whole inquartation process?
Question Street tips what does it mean when I do stannis chloride and I get a orange and purple on my paper a lot of orange and little purple it's like a oranges gold
Yes, I’ve used pure silver crystal, not recommended, sterling silver (best choice because I refine silver also). I’ve also used clean copper, and gold filled material.
Iron has too high melting point. Zinc is too high up the reactivity series. It would cause the gold to crumble during nitric boils - making separation of the liquid difficult.
@@sreetips I see. Thanks for always taking the time to answer questions! Appreciate it! This has definitely become my favorite you tube channel over the past year or so. Learning while being entertained, can’t get that on many other channels. 💪👍
In the near future I will be scrapping two computers with Pentium Xeon chips. Is there a way to send the CPU chips and other gold containing parts to Sreetips?
Have you ever considered separating and refining the other precious metals in your stock soup? I know someone who refines all precious metals, but specializes in electrolytic silver refinement. I know he does rhodium and that he has done iridium before, maybe he could let you know what’s involved in a practical sense to see if it’s something you’d do
Gold & silver are my primary metals. I’ve gotten platinum and palladium. Rhodium and iridium are enigmas to me. I’d love to learn about Rh & Ir. Most refiners would rather take their refining secrets to the grave with them rather than sharing how it’s done with the masses.
@@sreetips well in that case let me find out first if he’s willing to give any advice, that is if you’re interested. Probably not for iridium I’d guess, he said he used aqua regia which I know you’re comfortable with, but he also had to use a molten salt and chlorine, not to mention you won’t be able to melt it without a welders torch or an arc furnace
Wouldn't it have been possible to recover the gold from the nitric if it had been added the copper inquarted gold on the first boil? I think it might have just cemented out on the copper as the copper was put into solution. Maybe next time? :)
The silver contamination would still be there, although having it on first boil would get rid of it more thoroughly since it is at the start of the process. Just pouring it all onto the sterling silver and recovering through the slimes later as he did with the rest of it would avoid the contamination entirely.
It’s called inquartation. The original gold button wasn’t 99.9% pure gold. It had a small amount of impurities in it. You then inquart it with another metal (silver or copper) to approx. 28%. And then remove all the inquarted metal by repeated nitric acid boils ALONG WITH the original impurities. It’s the only way to pull out the impurities from the gold button. If you try to just dissolve the impurities out of the gold without inquarting, it will not work. The acid boils with not act on the “nearly pure” gold. The high gold content with prevent the acid from penetrating completely into the material.
If I remember correctly it came from his jeweler friends floor, not the floor of SREETIPS. In fact, I think it was collected from a drawer which had been used to gather desk sweeping over time. He did a floor sweep one a little while back and got a pretty small yeild from it, about a gram or so I think 🤔

If I have nitrous gases coming from the solution after Adding SMB, that means that I have excess nitric in the solution right?
Does that mean that I have to just add more SMB? Should I wait over night to have the AR eat up the percipitated gold and add more SMB the next day to re-percipitate it? Should I put it back on the heat?
Thank you for you help, much appreciated!
Greetings from Germany
Red fumes = excess nitric. A little don’t hurt, add more SMB to remedy. A lot of excess nitric will cause much heat and fumes. Adding more SMB could cause a boil over - especially while stirring.
@@sreetips Thanks for the quick reply. It all worked out I guess, everything settled at the bottom. Solution is pretty clear now. There might still be slight impurities in the gold powder as it didn't settle as quickly as in your video. What are those impurities and how would you get them out? Clean the gold powder and redissolve in AR or do the whole inquartation process?
I rinse the powder real good then dissolve and refine it a second time. If it’s still dirty - repeat until it’s clean. No need to inquart again.
@@sreetips Thank you!
Can U please teach us how to get the platinum and silver after purifying the gold
Yes, I get it from the stock pot
Question Street tips what does it mean when I do stannis chloride and I get a orange and purple on my paper a lot of orange and little purple it's like a oranges gold
Orange stannous is platinum - don’t get any of it on you.
What do you think of hydrazine acid to precipitate gold
DDG37 USS Farragut.. were you serving in the Navy?
I was a Farragut sailor.
Nice video
what's that brown smoke/fume? looks dangerous! :D
What other metals can be used for inquartation? If there are any others I mean…
Yes, I’ve used pure silver crystal, not recommended, sterling silver (best choice because I refine silver also). I’ve also used clean copper, and gold filled material.
@@sreetips you wouldn’t want to use anything like iron or zinc right? Wouldn’t be an easy process?
Iron has too high melting point. Zinc is too high up the reactivity series. It would cause the gold to crumble during nitric boils - making separation of the liquid difficult.
@@sreetips I see. Thanks for always taking the time to answer questions! Appreciate it! This has definitely become my favorite you tube channel over the past year or so. Learning while being entertained, can’t get that on many other channels. 💪👍
In the near future I will be scrapping two computers with Pentium Xeon chips. Is there a way to send the CPU chips and other gold containing parts to Sreetips?
Sorry, I only refine stuff we find together at local sales
Have you ever considered separating and refining the other precious metals in your stock soup? I know someone who refines all precious metals, but specializes in electrolytic silver refinement. I know he does rhodium and that he has done iridium before, maybe he could let you know what’s involved in a practical sense to see if it’s something you’d do
Gold & silver are my primary metals. I’ve gotten platinum and palladium. Rhodium and iridium are enigmas to me. I’d love to learn about Rh & Ir. Most refiners would rather take their refining secrets to the grave with them rather than sharing how it’s done with the masses.
@@sreetips well in that case let me find out first if he’s willing to give any advice, that is if you’re interested. Probably not for iridium I’d guess, he said he used aqua regia which I know you’re comfortable with, but he also had to use a molten salt and chlorine, not to mention you won’t be able to melt it without a welders torch or an arc furnace
Cool, thank you. But I won’t get to excited. Thank you.
@@sreetips ok
your torch tip is getting dirty . might want to clean it before it puts impurities in your metal
Really cool
Have you ever tried to refine raw gold ore? I'm curious about how it may differ from the process of refining karat gold.
Andy, no experience. It’s a totally different process
Wouldn't it have been possible to recover the gold from the nitric if it had been added the copper inquarted gold on the first boil? I think it might have just cemented out on the copper as the copper was put into solution. Maybe next time? :)
The silver contamination would still be there, although having it on first boil would get rid of it more thoroughly since it is at the start of the process. Just pouring it all onto the sterling silver and recovering through the slimes later as he did with the rest of it would avoid the contamination entirely.
@@ic_trab True...but with successive boils (I think he did 5) any silver should be rinsed out and contamination would be very minimal I'd think.

That´s why the KRUGERRAND gets the red colour
mr. sreetips are you a navy veteran? did you serve on the uss farragut?
i salute you sir!
Yes, from 1976 to 1980. Thank you

Could the crystal growth be nitrate crystals?
Do you have a website to provide your service to make gold bars from scrap?
Dave, sorry but I only refine stuff my wife and I find together. Thank you.
I don't understand, you fuse pure gold to copper, then chemically separate then, what is the point.
It’s called inquartation. The original gold button wasn’t 99.9% pure gold. It had a small amount of impurities in it. You then inquart it with another metal (silver or copper) to approx. 28%. And then remove all the inquarted metal by repeated nitric acid boils ALONG WITH the original impurities.
It’s the only way to pull out the impurities from the gold button. If you try to just dissolve the impurities out of the gold without inquarting, it will not work. The acid boils with not act on the “nearly pure” gold. The high gold content with prevent the acid from penetrating completely into the material.
That was on your floor ? Damn haha
If I remember correctly it came from his jeweler friends floor, not the floor of SREETIPS. In fact, I think it was collected from a drawer which had been used to gather desk sweeping over time. He did a floor sweep one a little while back and got a pretty small yeild from it, about a gram or so I think 🤔
@@JeffJeffers0n ah well either way.. one hell of a sweep lol
