Just wanted to thank you for teaching me this process over the years. I don’t operate with the volume you do but have done 6 refinings ending up with about a 10gr button of pure gold each time (xrf tested). It has been a great and rewarding hobby. Thanks again!
Finally! I was really looking forward to a new video refining. And there is going to be a part 2. Got my coffee, snuggling in bed and enjoying this moment in time with like-minded people. ❤
The watch you use as a timer is a testament to how corrosive it is inside the fume hood. It doesn't seem like that long ago it was shiny and new...Great video as always.
Seems the forceps have suffered as well, maybe next time you need a silicon coated one with roughened finger holes for a better grip? Silicon against standard issue rubber coated tines might be the answer. Seems like there would be a need for that and Korea would satisfy it.
While adding the Fe+2 solution, the Auric chloride solution becomes darker red just before a precipitate of Au forms. This is beautiful since you are making Au nanoparticles that are brownish-red due to plasmon resonance. You are doing some fancy nanomaterial synthesis 😃
First time watching any of your videos and NOT being a chemist or knowing much about metallurgy I found that very interesting. It was much more involved than I thought it would be. Yes I kind of thought it would be melt it, skim the impurity,s off and pour. Can't wait for part two.
I use an ultasonic cleaner at my job to clean the nozzles for my assembly machine. I make electronic circuit boards for the military. I love that cleaner works fantastic
Good evening Sreetips 🏴☠️🤠 I am now sitting on a pound of pure silver. Thats nice 👍 Im getting there. Thank you for sharing your refining video with us. Nice Work 🙏 God Bless
I’ve never tried it. It’s been recommended for some other applications - jewelers waste is notorious for have nano-particulate that loves to pass right through the filters. But for my gold refining just passing it through the same filter a second time usually clears it up for me. But I’ll see about getting some celite. Thank you.
If you were to start over again from scratch would you get the cheapest fume hood you can find, or would you spring for a fancy one? Do I need to do any additional processing of the exhaust?
Fancy isn't necessary, but I would recommend getting a good quality. As long as the worst your exhaust is spewing out is nitrogen dioxide in relatively small amounts, no additional processing is necessary.
Get one that is suitable for acid digestions - no metal parts. If I was starting over, I’d get a large 500 gallon poly-plastic tank with a six inch connection on top and make my own design. Install an “F” rated motor (high heat applications) and external mounted fan in the attic.
when you are sorting and labeling the gold you acquire.. can you include how much you pay for the gold as a whole or as you are sorting... would be appreciated
When you watch Sreetips videos time and time again and think maybe I could do that. Only to realise years and years of experience has bought this man to where he is now find it fascinating watching the process.
@@sreetips Yes, and make a water chiller as per the OP several episodes before recommended, as well as the fresh ice. You'll be able to start it up about 1hour before the shot drop and it will come in very handy when you do your cement silver as well. Still looking good Kevin!
I wouldn't inquart with silver crystal or cement. I'm sure you could, but from my understanding after many many videos, is that you want to inquart the sterling silver so you can then later on recover in the electrolytic silver cell for high purity silver. but I'm no expert. I just enjoy watching
That’s correct. Using cement silver is not recommended because palladium can build up in it and cause problems in the silver cell. Pure silver crystal is not recommended because it’s already been through the cell, be like taking a step backwards.
Where can I buy gold scrap without paying spot gold price for the scrap? I pour over eBay looking for precious metal lots and every one of them are asking spot or higher prices for the estimated gold content? I have followed you for years and I have built my lab according to your videos. Thank you for helping me and the other people here!!!
Try getting up early and going to yard sales. We used to find handfuls of scrap gold jewelry every week end about twelve or fifteen years ago when gold was at six or seven hundred.
Also, check estatesales.org for local sales. The pro sellers liquidate estates. And they sell gold jewelry for cheap sometimes simply because they don’t know what they have. You can find some good deals there.
The sand acts like boiling chips, which is what we use in the lab to prevent spattering. It provides a place for bubbles to form so that the liquid is less likely to superheat and cause a sudden steam explosion.
My wife found a nice hoard, about three grand in gold jewelry. But she didn’t have enough on her to buy it, they were asking five hundred for it. She only had about three. She called me, I went to the bank and got the money. But when I showed up, they had already sold it to someone else. You’ve got to have the currency on you when you’re looking. If you make a deal, then have to run and get the paper to pay for it, it almost always falls apart to someone else who has the paper dollars on the spot. I’ve gone to sales and got there a little late only to watch another buyer walking past me with a hand full of gold. It can be frustrating like that. But it goes both ways. I’ve walked out of a sale with a jewelry box full of gold jewelry just as one of my competitors is getting out of their car.
In the USA, you can still go that. Because people are clueless about gold and silver. Most Americans believe, incorrectly, that paper dollars are more valuable than silver and gold. This lack of understanding creates some fantastic buying opportunity to convert your failing paper currency into real wealth; good and silver. But the times are changing. And once folks begin to realize that their paper currency is becoming worthless, it’s only going to get worse. But for now, I’m buying everything I can get my hands on.
What if you poured the melted gold and silver into a small, elongated bar and flattened it? Like jewelers do between rollers or with a hammer on an anvil ;) You can use rollers to make a thin sheet that will be digested faster than pellets.

I believe that you’re supposed to add the sand to the bottom of the beaker to give the steam a point to titrate… It’s like adding glass chips commonly known as boiling chips
In order for a sand bath to work you need a thicker layer, at least half an inch. Als long as there is solid gold in the beaker boiling chips ar not needed.
In these later nitric acid boils on the inquarted gol you might want to skip the water and just put the nitric, it seems that the higher the strength of the acid the better and if you don't dilute it you might not need as many boils.
The water is needed to provide a medium for the dissolved metals to go into. Think of using just liquid dish soap to wash your hands. It would get them clean, but adding a little water would make the soap work much more efficiently. Same with adding water to dilute the nitric acid.
Azeotropic nitric acid is 33-35% water and the final few grams of base metals and silver should be able to dissolve into it. Yu could also put the nitric in first and then after it has had time to do the work you could put in a splash of water. Mind you I am only talking about the last couple of boils.
@@fenrisulfur666 this will work and does not need heat to strengthen or enhance the dissolution reaction. Pouring water into standard strength acids is not recommended for several reasons, check out why, there might be a video for demonstration!
Do it as you oughta put your acid into water. The thing is azeotropic nitric and hydrochloric acids will have a fair amount of water in them, that is 35% and 73% respectively and them being azeotropic you cannot get them stronger by boiling them. I assure you that it is not a problem to add water into these acids, even boiling. If you have anhydrous 18M sulfuric being heated much higher than the boiling point of water and put water in it then maybe it can get a little sporty but just about every other "normal" acid is alright. Sreetips himself puts ice cubes into aqua regia after all.
Because the crystals are beautiful and pure already, so inquarting with them is a waste of the effort it took to make them. As for the cement silver, something similar applies. You already pulled the silver through your acids, so why inquart with it when you're going to cement it later? In short it's just not very efficient. That being said, if for some odd reason you can't find enough sterling, you can recycle the silver you have on hand, yes, because an atom of silver is an atom of silver, no matter the form. Another good reason to always inquart with sterling is the likelihood that you come through on occasion with a few atoms of gold that was on the sterling in the form of plate or accents make of karat gold. This is added to your gold you are deliberately refining.
Because the cement silver has a much lower concentration of copper so you loose the blue color indicator that lets you know when the base metals have been removed. Also, the cement silver tends to have higher concentrations of metals that are undesirable for your refining inputs such as PGMs, Lead, and Tin. You can use it but it’s likely to cause issues throughout the refining processes.
I wouldn't waste my hard earned crystals to do it I was just curious if it was possible if you adjusted for the purity. I'm going to assume that old 90% silver would work just as well, again with a slight adjustment for purity. I plan to refine my first gold here soon. I just need a few more pieces of karat to make a decent run. I will be using sterling to inquart.
Yes, but it’s not necessary because for some strange reason the gold seems to settle very quickly after FeSO4 precipitation. Or maybe it just looks that way because the solution turns so dark that I can’t see if the gold has actually settled or not.
Enjoy your video for the last 6 yrs Have a question I started a new batch of 10 k -- 14 k gold I did the formula to all the grams added the silver according to the formula the first boil of the nitric acid the color was very purple
And no more fumes on the first boy of the nitric acid the color is still purple can you please give me some advice on this I know the color purple is gold
Purple is colloidal gold. I’d say you added too much silver. Or a piece of non karat gold got counted as real gold. Ive had this happen when I first started. A common beginner mistake.
Piranha solution works best on organic compounds, not metals. However, I wonder how it would work for something like filter paper recoveries or the bobbing compound from his jeweler friend. Those both seem to jam up filter papers, but with piranha solution all the hydrocarbons would be reduced to water and co2 basically. Something to think about.
Why dilute the nitric acid wouldn't it be better if it were just the acid can it only consume only so much at a time and needs the water to put it in solution I've heard you talk about it being dehydrated before but then you put more acid in just wondering
Adding the hydrochloric acid actually adds a good deal of water since it is still a dilute solution. Standard concentration is around 37-38 percent since it will evaporate very swiftly above that concentration. Dilute means usually a 50/50 mixture but that can vary depending on the acid and actually on the mood of the chemist. Always best to err on the more dilute rather than more concentrated since the metals need something in which to dissolve or accumulate. Dehydration in a reaction is always a bad thing just like it is in a human!
So i have a question, well two actually. Why do you shake the beaker to stir rather than using a stir stick? And secondly why do you wear leather gloves and not those big runner gloves when handling these chemicals?
1) a glass rod puts marks in the glass inside the beaker and it’s easier to give it a swirl. 2) sometimes I’m in a hurry and just throw those leather gloves on because they’re easier to put on my hands.
@@sreetips leather works well enough for all the cow chemists I know. Other than the occassional drop of surfuric, nitric, hydrochloric, they have held up very well. Just don't wash them unless you neutralize the acids first. They would fall apart fast I imagine. And the glove dryer needed is a bit on the extreme side of tres chic.
@@sreetips a silicon coated rod might not scratch the glass, or try a bamboo chopstick double dipped in tool coat. Good luck finding a deep but narrow coating tray if you go the diy way.
Hey Mr. Sreetips! I want you to try out a procedure using thionyl chloride (SOCl2) + pyridine or N,N-dimethylformamide (DMF) instead of using aqua regia. The pyridine or DMF, (should be able to use either one) are aprotic polar organic solvents. I would suggest the DMF because it’ll be difficult to get the pyridine. Anyhow, it may be cheaper than nitric acid and you’ll just have to research some ratios for mixing
None of the pro refiners that I learned from used anything like that. My jeweler friend’s dad used to refine in the alley behind their jewelry repair shop. He used cyanide to dissolve the gold. One time, the wind shifted (they weren’t using a fume hood) and some of the cyanide gas wafted through the open door into the repair shop. My jeweler friend told me that his tongue and lips swole up, and he watched a fly fall dead in mid flight. I’m not a chemist. I’m all self-taught with help from some refiners who have way more experience than me. I wouldn’t even know where to get those compounds. They sound dangerous.
I've always wondered, as that stannous chloride turns the paper black, what would happen if you poured the whole bottle of it in to the gold solution? Would that destroy the gold or just turn it black, and i wonder if the gold can still be recovered after that? Also, do you keep all them test strips? Because it may be a tiny worthless bit of gold on 1 test strip, but you have done probably thousands of stannous chloride tests over the years, thats got to add up to a worthy amount to recover right?
Yes, but it sends the indicator up into the diamond range much slower. A real diamonds slings it up fast and hard. After you’ve seen it you can start to tell if it’s diamond or moissanite by how it reacts with the tester.
I was surprised that you didn't use a stir bar to help dissolve the ferrous sulfate. Does the iron content in the powder interfere with the magnets in the stir plate?
@@sreetips I meant writing the word on the funnel not putting it in. It seems you always forget to put it in the solution before filtering... That's why it might help.
I’m looking for a dog tag style pendant, nothing on it. If you have one for sale i would really appreciate. Love your videos, I’m in Canada. I know i could just go buy one ,but it would be Awesome if i could get one from you. I wana do a Medic Alert Charm.
Out of curiosity do you keep the filter paper you use for the stannous tests? I know it's going to be an absolutely miniscule amount but it's still there.
tips, bless you, your knowledgable lovely wife and family ,as a talented artist and all around high i q gentalman, i hope you have a retainable castle that is difficult to storm, in the comming days, we,d hate to seee you with you lol ,pants down be set for some bedlum...... keep safe till we regain big tec, and the presidency.... vote for your freedom to do the best a man can do.
The world is a dangerous place to live. All is not well, but I believe that all is as it should be. Thank God there’s an end to this madness. Can you imagine being stuck here forever? I’ll cast my vote. But it’s in God’s hands. I put my faith and trust in Him. Because it is to Him that I’ll return. We live on a beautiful planet, created by God, owned and operated by the Devil.
Why do you list your weights 14k, 10k, 18k instead of in order 10, 14, 18? I know it's trivial, but you consistently do it in all your videos. So I was curious for the reason.
It’s some weird tradition (within my own mind) sequenced in most common form of karate: 14k, then the next most common: 10k, and finally the least common: 18k. But then, it’s backwards going right to left instead of left to right. That’s how I started doing it. And it just stuck.

Another great video. Would you think it would be worth the investment to buy an electric cauldron to melt the metals and using solar panels to cut down the overhead? I mean, at first the cost would be expensive. But on yhe long run it would pay for itself. What are your thoughts? 😎👍🇨🇦
I am always here for a Sreetips refinement session. A joy to see. So zen.
Just wanted to thank you for teaching me this process over the years. I don’t operate with the volume you do but have done 6 refinings ending up with about a 10gr button of pure gold each time (xrf tested). It has been a great and rewarding hobby. Thanks again!

Resist the urge to convert it into more paper currency. Silver (and gold) are real money, real wealth. Put it away and forget about it.
Dear Sreetips, I suggest using a Celite pad for the suction filtration.
Diatomaceous earth!

This is added to your gold you are deliberately refining.
Because the cement silver has a much lower concentration of copper so you loose the blue color indicator that lets you know when the base metals have been removed. Also, the cement silver tends to have higher concentrations of metals that are undesirable for your refining inputs such as PGMs, Lead, and Tin. You can use it but it’s likely to cause issues throughout the refining processes.
I wouldn't waste my hard earned crystals to do it I was just curious if it was possible if you adjusted for the purity. I'm going to assume that old 90% silver would work just as well, again with a slight adjustment for purity. I plan to refine my first gold here soon. I just need a few more pieces of karat to make a decent run. I will be using sterling to inquart.
Curiosity question. Can you boil the Feris sulphide solution like you can with an SMB solution after precipitation, or is that not advised??
Yes, but it’s not necessary because for some strange reason the gold seems to settle very quickly after FeSO4 precipitation. Or maybe it just looks that way because the solution turns so dark that I can’t see if the gold has actually settled or not.
@@sreetips yup, the ionic attachment with SMB is overcome with heat, not needed with ferrous sulfate altered with hydrochloric acid.
Those Amethyst earrings would look good on you mate 😆
Unfortunately, my wife would divorce me, and I don’t have pierced ears.
@@sreetips The first would be an issue, the latter could be corrected.
Enjoy your video for the last 6 yrs
Have a question I started a new batch of 10 k -- 14 k gold I did the formula to all the grams added the silver according to the formula the first boil of the nitric acid the color was very purple
And no more fumes on the first boy of the nitric acid the color is still purple can you please give me some advice on this I know the color purple is gold
Purple is colloidal gold. I’d say you added too much silver. Or a piece of non karat gold got counted as real gold. Ive had this happen when I first started. A common beginner mistake.
Thank you so much for your information is the first time that's happened to me in the since I've been doing this for 6 years already
How much refining do you do off camera?
Almost none. If I have some material to refine I always end up with a camera right in the middle of it all.
Another good vid 😎👍
Hey Chief, could you use Pirahna Solution to either separate the silver or purify the gold??
Piranha solution works best on organic compounds, not metals. However, I wonder how it would work for something like filter paper recoveries or the bobbing compound from his jeweler friend. Those both seem to jam up filter papers, but with piranha solution all the hydrocarbons would be reduced to water and co2 basically. Something to think about.
No, it won’t dissolve gold, I’ve tried it.
That’s a good idea. I think I did use some piranha solution in one of the jeweler’s waste recover videos to remove some carbon and it worked good
@@sreetips If I remember correctly more than one. And yes, it worked very well.
Wow, you've got a lot this time.
King of Inquartation.
Why dilute the nitric acid wouldn't it be better if it were just the acid can it only consume only so much at a time and needs the water to put it in solution I've heard you talk about it being dehydrated before but then you put more acid in just wondering
The water provides a medium for the dissolved metals to go into.
Adding the hydrochloric acid actually adds a good deal of water since it is still a dilute solution. Standard concentration is around 37-38 percent since it will evaporate very swiftly above that concentration. Dilute means usually a 50/50 mixture but that can vary depending on the acid and actually on the mood of the chemist. Always best to err on the more dilute rather than more concentrated since the metals need something in which to dissolve or accumulate. Dehydration in a reaction is always a bad thing just like it is in a human!
So i have a question, well two actually. Why do you shake the beaker to stir rather than using a stir stick? And secondly why do you wear leather gloves and not those big runner gloves when handling these chemicals?
Who cares why he does either of those. It's up to him how he handles the chemicals etc etc.
1) a glass rod puts marks in the glass inside the beaker and it’s easier to give it a swirl. 2) sometimes I’m in a hurry and just throw those leather gloves on because they’re easier to put on my hands.
@@sreetips leather works well enough for all the cow chemists I know. Other than the occassional drop of surfuric, nitric, hydrochloric, they have held up very well. Just don't wash them unless you neutralize the acids first. They would fall apart fast I imagine. And the glove dryer needed is a bit on the extreme side of tres chic.
@@sreetips a silicon coated rod might not scratch the glass, or try a bamboo chopstick double dipped in tool coat. Good luck finding a deep but narrow coating tray if you go the diy way.
Hey Mr. Sreetips! I want you to try out a procedure using thionyl chloride (SOCl2) + pyridine or N,N-dimethylformamide (DMF) instead of using aqua regia. The pyridine or DMF, (should be able to use either one) are aprotic polar organic solvents. I would suggest the DMF because it’ll be difficult to get the pyridine. Anyhow, it may be cheaper than nitric acid and you’ll just have to research some ratios for mixing
None of the pro refiners that I learned from used anything like that. My jeweler friend’s dad used to refine in the alley behind their jewelry repair shop. He used cyanide to dissolve the gold. One time, the wind shifted (they weren’t using a fume hood) and some of the cyanide gas wafted through the open door into the repair shop. My jeweler friend told me that his tongue and lips swole up, and he watched a fly fall dead in mid flight. I’m not a chemist. I’m all self-taught with help from some refiners who have way more experience than me. I wouldn’t even know where to get those compounds. They sound dangerous.
I've always wondered, as that stannous chloride turns the paper black, what would happen if you poured the whole bottle of it in to the gold solution? Would that destroy the gold or just turn it black, and i wonder if the gold can still be recovered after that?
Also, do you keep all them test strips? Because it may be a tiny worthless bit of gold on 1 test strip, but you have done probably thousands of stannous chloride tests over the years, thats got to add up to a worthy amount to recover right?
Tin is the enemy of precious metals. Except when it comes to stannous chloride. I started saving the test strips.
if you used a spinning block of wood or something i think that would help with some of the clumping you get
To avoid I must chill the water first. It was room-temp and that’s why it stuck together.
Can moisenites fool a dimond tester
Yes, but it sends the indicator up into the diamond range much slower. A real diamonds slings it up fast and hard. After you’ve seen it you can start to tell if it’s diamond or moissanite by how it reacts with the tester.
Gold in solution after filtering is just so pretty.
Especially when it’s clear and bright.
I was surprised that you didn't use a stir bar to help dissolve the ferrous sulfate. Does the iron content in the powder interfere with the magnets in the stir plate?
No, it dissolves easily without a stir bar
Nice a steamer.
And seriously, write on the funnel H2SO4 maybe this will work... Me I sometimes put things in my shoes not to forget them before leaving. Works...
Sulfuric acid will dissolve the filter paper. This will NOT work.
@@sreetips I meant writing the word on the funnel not putting it in. It seems you always forget to put it in the solution before filtering... That's why it might help.
I get cha
Nice!
I’m looking for a dog tag style pendant, nothing on it. If you have one for sale i would really appreciate. Love your videos, I’m in Canada. I know i could just go buy one ,but it would be Awesome if i could get one from you. I wana do a Medic Alert Charm.
I’ll keep a close eye on.
@@sreetips thanks and it can be silver
The sand is a very good idea. However, you really want a 1/8" to 1/4" layer of it.
Out of curiosity do you keep the filter paper you use for the stannous tests? I know it's going to be an absolutely miniscule amount but it's still there.
I’ve started saving them

The world is a dangerous place to live. All is not well, but I believe that all is as it should be. Thank God there’s an end to this madness. Can you imagine being stuck here forever? I’ll cast my vote. But it’s in God’s hands. I put my faith and trust in Him. Because it is to Him that I’ll return. We live on a beautiful planet, created by God, owned and operated by the Devil.
What was your reasoning for processing the white gold separately from the yellow gold scrap?
For the shop
Just curious! I have a few pieces of sterling marked 925 5% 10k what does that actually mean
Some 925 jewelry items have karat gold embellishments. Like a 925 silver bracelet with a 10k gold sale boat attached to it, as an example.
Just can't watch you melt those serving pieces.
Your link to the ring is wrong
I’ll check it out. Thank you.
I was dog tired and put the link to the video instead. I fixed it. Thank you.
@@sreetipsGod bless your hart my friend 🔥🌺
Wouldn’t moissanite also test as diamond with that tester?
Yes, but not the same.
The tester moves slowly with moissanite. A real diamond slings it up right quick.
Why do you list your weights 14k, 10k, 18k instead of in order 10, 14, 18? I know it's trivial, but you consistently do it in all your videos. So I was curious for the reason.
It’s some weird tradition (within my own mind) sequenced in most common form of karate: 14k, then the next most common: 10k, and finally the least common: 18k. But then, it’s backwards going right to left instead of left to right. That’s how I started doing it. And it just stuck.
@@sreetips And like any meditation, tradition, mantra, soothing is the key. So, turn your hats to a jaunty angle and batter up!

I'm surprised you left the backs on the posts while cleaning them
The elephant bracelet needs to be melted and refined.
Inquarted and refined
The watch in the background is looking worse for wear.
It takes a licking and keeps on ticking.

Another great video. Would you think it would be worth the investment to buy an electric cauldron to melt the metals and using solar panels to cut down the overhead? I mean, at first the cost would be expensive. But on yhe long run it would pay for itself. What are your thoughts? 😎👍🇨🇦
I’ve used a torch and store-bought electricity for a decade and a half with excellent results. Solar panels, around here, are a gimmick.
First comment lol. Another great video!
Almost but I got ya by 10 seconds 😂😂
I can’t believe RUclips finally did something about those bots wearing thongs and making the same random comments on every sreetips video

Do you regret not remelting the alloy...might have made things easier, no.
No, it went just like I thought it would. Because I’ve had much experience with that.
