Makes we wish I paid more attention in Highschool chemistry lab lol Funny how a subject that bore us as children fascinates us as adults. Geology is something else I wish I had paid closer attention too
I just never get tired of watching the gold drop out of that clean, clear chloroauric acid. It's just magic seeing that caramel colored broccoli form in the bottom of the beaker!
Love your inquaration videos, maybe even more than the silver cell ones. This one was a real pleasure: got a real sense of the workaday plate-spinning that must go on with multi-metals multi-refining. Keep up the good work, and have a great weekend.
As soon as teh video is posted, I started watching and half way through fell asleep. Now again I watch from the biginning. A beautiful gold bar. After watching your informative videos for quite some time, I subscribed to you.
Here again, I find myself before bed watching sreetips playing with chemicals and making nice bars of precious metals . Why is this so satisfying to watch?
Gorgeous. I was enamored with the process , couldn’t take my eyes off it. You my friend are a very talented man! Kudos! I wish I could afford this, more importantly learn how you do it correctly! Thank you for sharing!
I remember when I asked that same question sometime about a year and a half ago. It really seems counter-intuitive until you explain the reasoning. For me, some further research was required after reading the youtube comment replies to my question, but once I researched it, it makes perfect sense. Thanks for the videos as always!
My favorite kind of video from SREETIPS!! A one hour gold recovery and refining video!! Had to look up the word you used during the first drop!! You keep me on my toes with some of these words you use!! ;) Have a GREAT Day My Friend!!!!
Note: Take all the precautionary safety steps while doing the experiment. 1) Reduce the % of the scrap gold to about 25% by melting it with sterling silver. 2) reduce the thickness of the molten metal by pouring it in the water, in a steel container. 3) put the metal in a beaker, boil it with nitric acid and pour the blue colored solution formed after boiling the metal solution, into another jar. ( From this blue solution, the silver is extracted by settling it with copper plates in another jar after extended period of time. ) 4) The metal in the beaker is rinsed with distilled water and poured into the silver-nitric acid solution jar. And it is added with diluted nitric acid, boil to extract the silver and other platinum group metals. This step is repeated until a clear solution is formed. 5) To the precipitate add hydrochloric acid and boil by adding sulphuric acid with a dropper, to eliminate any lead or other metals. The formed solution is then filtered out, cooled down by adding ice and precipitated by adding sodium-metabisulphate. The brown-waste solution formed in the beaker is collected into another jar, leaving the brown-gold metal in the beaker. This process is repeated until a clear solution is formed. 6) The brown-gold powder is then melted to get pure gold.
Are you a teacher ? If not, you do it perfectly ! It"s a great pleasure to follow you and learn from your experiences. Among all "gold refiners", you stay from far, the best. In fact, you describe, with calculations, all what you do and the perfect moment where you do it. Thanks a lot for this. Sylvain
1,000 troy ounces in the last 10 years is probably a fair to somewhat low estimate! 1,000 troy ounces in today's market is about 2 million dollars, not to bad for what started as a hobby and still might be a very dedicated hobby! Most hobbies cost 2 mil, not gross 2 mil... good on you my friend!!! I've seen every video some multiple times and it's cool to see your video quality getting better and better over the years!! Have a GREAT Day My Friend!!!
$2,000,000.00 is today's gold rate, but not included is all the platinum, palladium and probably a ton of silver... maybe not a ton, but who knows! I guess Sreetips might have a guesstimate on that. My guess for a 5oz. Silver bar challenge is 11,700 ounces!! Lol Kidding on the 5oz, but the guess of 11,700 oz is an educated guess of 25oz. a week times 9 years! I took off a year because I'm guessing you weren't doing 25 a week at the beginning and I bought it down to 25 to average it out. I'm guessing you're doing well over 30oz a week for several years now!! If you read this Sreetips let me know what you think about my math and my knowledgeable guess on the silver. If I'm way off or whatever tell me. Like you I have thick skin, can't hardly offend me my friend!!
59:56 If I had to guess, it would be that you're adding a liquid solution, in part, with the gold. As to why you're getting the "spitting/bubbling" action. The solution is probably having to boil away before the metal can actually melt. You've taught all of us so much, however, with my guess, I'd suggest you dry your gold powder on a hot plate before melting. If you have any other idea as to why it's bubbling/spitting, I'd like to know. Thank you for your beautiful educational videos!!!!
The metal will absorb oxygen during the melt. Then it spits it back out causing the metal to appear to boil. Tiny balls of gold get ejected when this happens. I solved it by turning down the flame. No more spitting but it takes longer to melt. Silver is worse than gold for this tendency.
Yep, you're right. Never pick up a large full beaker by the side. I did that once on a 2L beaker containing isopropyl alcohol. As I picked up the beaker, it fell to the floor leaving me with a handful of broken glass. I'll never forget that day because I was fired.
rap the back of the torch real good ,If orange flame comes out your tip is choked with carbon . .Clean the tip or get a new one .If you don't you will eventually contaminate your gold . Turn your torch up a bit .I am a welder I use a torch allot every day for many years
sreetips i believe your issue with your gold clumping on your cooling pot, is that your pot isnt deep enough. i would suggest, getting a much much taller pot, which is also as wide as you have and fill it most of the way up, to give the gold more time to cool on its way down... also, maybe pour higher up from the water, to allow the gold to break apart? just my thoughts on it, your the professional! keep making these great videos!
Such a beautiful bar! Absolutely nothing wrong with your price. Its very common for a $30 - $40+ per oz premium on poured gold bars. Anyone with any precious metals experience will know, and expect that.
@@thomasloanwolf check your math. Its a 3.275 Troy ounce bar. He only added the 1st digit in his calculation. Do the actual weight and he's actually asking a little over $61/oz premium. That's actually a cheaper premium than a lot of sellers ask for poured.999 fine gold. Poured gold bars always go for more. You're paying for the metal, plus the man hours to refine and work it. Even at $90/oz premium. Here's an example: prospectorsgoldandgems.com/gold/

How does one go out to find gold plated jewellery. Garage sales. Car boots sales or just keep an eye out. I have a bit of computer scrap but don't know how to process it. The UK is hard to get chemicals but I know it can be done. Brilliant video always nice to see someone save precious metals much respect.
My wife gets the gold plated at local sales. We pick through and remove the karat gold scrap and the gold filled scrap. I save the plated scrap so I can make videos with it.
Hi Sreetips! I enjoyed your video as usual. However let me please contribute with something: When you state you need to dissolve extra Silver to avoid needlessly consuming Copper, you are making a fundamental mistake. You will need to consume the Copper anyway to cement the extra Silver you dissolved, so you may be better off just adding the Copper from the beginning. Demonstrating it is easy. When using Silver: Ag + 2HNO3 → AgNO3 + NO2 + H2O When using Copper: 4 HNO3 + Cu → Cu(NO3)2 + 2 NO2 + 2 H2O Multiplying the first equation by 2, reverting it to cement the Silver and subtracting from the second one: 2AgNO3 + Cu → Cu(NO3)2 + 2 Ag Which demonstrates that you will need the same amount of Cu either to consume the HNO3 or to cement the silver you used to consume it. You will always spend the same amount of Copper regardless... Cheers!
If there’s a whole bunch of excess nitric in the silver nitrate solution then when copper is added it will get consumed, needlessly, until it’s almost completely used up. It’s best to boil the silver nitrate and make sure there’s some undissolved silver left in the reaction. This will ensure that the excess nitric gets consumed before adding the copper to cement it out. Excess nitric will dissolve the copper and the cement silver will go back in solution, cement out, go back in solution, cement out .... over and over until the excess free nitric gets consumed.
@@sreetips Hi Sreetips. I agree that it is better to have a stoichiometrycally precise mixture to avoid excess HNO3 in the first place. Boiling out the excess HNO3 is also an option but that is not what you usually do, you usually add extra silver stating that "Copper will be consumed needlessly". My point is that once you have the excess HNO3, the same amount of Copper will be consumed no matter what, whether it is cementing the extra silver added or dissolved by the acid. Therefore, even if the goal is to purify extra Silver taking the opportunity of the unused HNO3 it is irrelevant whether you add the Silver or not, you are not saving Copper in the process...
At 3:48 you walk into the garage where the left torch is jut balanced on the stock pot....dude I’d it rolled off, fire. Stay safe! Your videos are too good for some stupid tremor to burn your house down
I see shapes in there at 8:07 that I could describe as Fairy Tale or Mother Goose. If I had the money, I would have bought it just like that as a one of a kind wall hanging, it's really cool.
7:50 once again, it is almost art in itself as is, I am wondering if it not more valuable in an art form such as it is over the price you ll get when the metals are separated and sold as bullion. Edit: it is really interesting to learn how you separate out each metal out, you talk a lot but you don't say Bullsh** which makes it even more interesting.
I have never seen gold before in real life(unless I seen it in an electronic component or something).. it sure looks beautiful on screen., Wish I could afford a piece like that or smaller.
@Sreetips, It would be awesome if you do an inquartation of .999 fine gold and .999 fine silver, for your chess set’s opposing side. That way you could say your chess set only consist of gold and silver and no other bass metals. Plus it would cool to see what 6k gold made with only .999 fine gold and .999 fine silver would look like or, would it turn out only looking like silver IE white gold? If so it would be neat to use .999 fine copper too. At least at that point you could still call it you your .999 fine set of only three metals. P.S. love your videos, your awesome! Keep up the great work. Have yourself a great weekend.
Believe it or not, I tried an alloy of pure silver and pure gold and it just looked like white silver metal. It’s the copper in the sterling silver that gives the inquarted gold an iridescent look.
Have you tried gluing glass like that handle using epoxy or PL Premium which is what I use. PL seams to glue anything to anything and is inexpensive. I am not sure how it will fare with all the acid vapor in your case, but it may be worth a try. Make sure your surfaces are clean and roughed up with sandpaper. Thank you for all your effort getting these videos on line.
Will you talk about your melt dishes. Some you have comented about just for gold, unclean, ect. What is the junk from your melt dish? Why the large stack of melt dishes. Thank you for your time. Great entertainment.
Hey Sreetips watch one of NileRed's refining videos and pay attention to his rinsing method I think you'll like it and will save you on the amount of hcl you use
Question regarding the process - rather than 92.5% silver, could you use an alloy of 50% silver, 40% copper, 5% zinc and 5% nickel? Reason I ask is that I’d prefer to use old coins as the catalyst as they are readily available here in Australia and can often be bought for less than silver spot price.
Man... I have to say, this being my first video to have watched here, I have to consider the first people that ever developed these methods and how they could possibly have ever known what cocktail of dangerous chemicals to combine, in what order and under what conditions and durations, so precisely, in order to achieve these desired results. And, how did they even know what the results were supposed to be before they began their experiments? Clearly, I didn't spend much of my attention studying in my singular chemistry class in high school... not that they would ever have covered anything like this, I would have remembered that much at least, positively. So, if it is obvious, based on what they are and the inherent properties of each compound or element, I apologize, in advance, for having posed any uneducated questions.
Alchemy, people searching for a way to turn lead into gold, is the predecessor to modern chemistry. So I’ve been told. Today we know that the only place with pressures and temperatures high enough to fuse protons into heavier elements is in a super nova when a massive star collapses.
Around 35.51, you add sulfuric acid to precipitate lead that might be present. Then you add nitric till everything in the beaker is dissolved. Would the lead remain precipitated, or dissolve again with the added nitric? Could the final crumbs have been lead? Building my understanding of the different processes. Not doubting yours, only trying to understand fully.
Lead sulfate will not redissolve in nitric. Im merely adding the sulfuric just in case any lead might have made it that far into the process even though this is highly unlikely. I learned this from on old refiner. He taught me to add just a little sulfuric every time I dissolve the gold whether I suspect lead to be present or not. It hurts nothing and provides a huge benefit. Lead, in just trace amounts, will ruin the ductility and malleability of the gold. Adding a few drops of sulfuric acid guarantees that all of the lead will be 100% removed during the refining.
I’m going to mention that when Sreetips says that all silver must have been removed because of nitric treatments , he means all but 19% to 0%,,, Aqua Regia will dissolve and keep less than 20% by content , silver in solution,, two ways to extract that 19%or less out of solution is to evaporate solution to concentrate solution off setting the % by content or use stock pot,, but more usually rinsing well avoids this from taking place
Can you bubble the reddish NO2 gas through some water to recover the nitric acid? It would cut down on air pollution and help reduce the cost of nitric acid, right?
It would be cool to see how much silver you pull out after a refining like this, making an estimated guess based on what you started with... Love your vids as always.
I think I would probably just use distilled water for pouring the inquarted gold, and keep it in a lidded pot, and reuse it every time... I mean, even at 10x the price, it's only like $2-3 worth of water, and considering the number of runs you could do before you would need to replace it, and the amount of time it would save in the long run, it seems like it would be more time and cost effective...
I had a window AC unit. I kept a 5 gallon bucket under to catch condensate. It’d fill up in a couple days. Thought about filtering and using that for my experiments.
That 6k gold and silver alloy you are making your chess pieces with is called electrum. It was very popular in ancient times. It has a amazing look and conductive properties.
@sreetips how efficient is your process? If someone drops off 100g of 14k are you getting 58g of pure gold? Do you get anything else of value out of the refining process? Awesome videos I can’t stop watching!
@sreetips at 35:01 you say that is close to three nine fine the brown gold, why not just put that into a crucible and melt? Why was it necessary to put the gold back into solution and precipitate it yet again using the stump-out?
Close to three nines is good enough for a jeweler making alloys for some new jewelry. But the only way to be sure of three nines is to refine it with a wet chemical process to get trace impurity’s out, twice.
I had a laugh when I heard the jingle of the RING you have installed in your house. My family recently installed a RING system, and we're a few weeks in and still getting used to the kinda annoying - but useful - noises it makes!
Arne, it’s used to disinfect containers in wine making. But the actual “Stump Out” by BONIDE that you see frequently in my videos, is specifically for dissolving tree stumps. The directions say to pour it directly on the tree stump that you want removed, and in time it will eat the stump away. Instead of having to grind it out of the ground, theoretically, you can dissolve it out of the ground. I don’t know how effective it is. I’ve never tried using “Stump Out” on a tree stump.
If aqua regia was made 4:1 and the nitrogen was not evaporated out of the solution before the precipitation phase, how can you get the nitric acid out? Do you just boil with no additives until you get that yellowish color or do i need to add something to get the nitric acid removed?
You can rid the gold solution of excess nitric by evaporation to a syrup, then rehydrating with HCl. Repeat until no more brown fumes evolve upon adding HCl. I’ve done it, it’s time consuming but it works. Or you can add sulfamic acid. But make sure lots of extra space because it will foam over
Yes, 14k white gold has the same exact amount of gold in it that 14k yellow gold has. For white gold they increase the amount of white metals, palladium, nickel, silver and/or zinc and reduce the amount of copper. For yellow gold the amount of copper is increased and the proportion of white metals is decreased. But both have the same amount of yellow gold in them.
I have a question at 36:00 you added sulfuric acid and then a minute later you called it nitric acid, was that a mistake or is there a difference if someone uses either or in that process? Thank you
I added sulfuric to remove any lead that may be present. It combines with any dissolved lead to form lead sulfate then it can be filtered out to remove 100% of the lead from the gold.
I think the reason why sreetips doesn't use the handle is because the handle is being held on by a corroded metal strap that may break loose at any minute.He doesn't want silver all over his floor. My coffee pot I use no longer has a handle on it because it had a metal band on it and broke off after the second or 3rd time I used it. Nitric acid is a very corrosive chemical.
You have renewed my love of chemistry and science these videos are so cool

I so wish I paid way more attention inschool almost makes me want to change career focus

Note: Take all the precautionary safety steps while doing the experiment.
1) Reduce the % of the scrap gold to about 25% by melting it with sterling silver.
2) reduce the thickness of the molten metal by pouring it in the water, in a steel container.
3) put the metal in a beaker, boil it with nitric acid and pour the blue colored solution formed after boiling the metal solution, into another jar.
( From this blue solution, the silver is extracted by settling it with copper plates in another jar after extended period of time. )
4) The metal in the beaker is rinsed with distilled water and poured into the silver-nitric acid solution jar. And it is added with diluted nitric acid, boil to extract the silver and other platinum group metals.
This step is repeated until a clear solution is formed.
5) To the precipitate add hydrochloric acid and boil by adding sulphuric acid with a dropper, to eliminate any lead or other metals. The formed solution is then filtered out, cooled down by adding ice and precipitated by adding sodium-metabisulphate. The brown-waste solution formed in the beaker is collected into another jar, leaving the brown-gold metal in the beaker.
This process is repeated until a clear solution is formed.
6) The brown-gold powder is then melted to get pure gold.

At 3:48 you walk into the garage where the left torch is jut balanced on the stock pot....dude I’d it rolled off, fire. Stay safe! Your videos are too good for some stupid tremor to burn your house down
I see shapes in there at 8:07 that I could describe as Fairy Tale or Mother Goose. If I had the money, I would have bought it just like that as a one of a kind wall hanging, it's really cool.
7:50 once again, it is almost art in itself as is, I am wondering if it not more valuable in an art form such as it is over the price you ll get when the metals are separated and sold as bullion. Edit: it is really interesting to learn how you separate out each metal out, you talk a lot but you don't say Bullsh** which makes it even more interesting.
I have never seen gold before in real life(unless I seen it in an electronic component or something).. it sure looks beautiful on screen., Wish I could afford a piece like that or smaller.
@Sreetips, It would be awesome if you do an inquartation of .999 fine gold and .999 fine silver, for your chess set’s opposing side. That way you could say your chess set only consist of gold and silver and no other bass metals.
Plus it would cool to see what 6k gold made with only .999 fine gold and .999 fine silver would look like or, would it turn out only looking like silver IE white gold? If so it would be neat to use .999 fine copper too. At least at that point you could still call it you your .999 fine set of only three metals.
P.S. love your videos, your awesome! Keep up the great work. Have yourself a great weekend.
Believe it or not, I tried an alloy of pure silver and pure gold and it just looked like white silver metal. It’s the copper in the sterling silver that gives the inquarted gold an iridescent look.
I.E. “one of your other videos”

Have you tried gluing glass like that handle using epoxy or PL Premium which is what I use. PL seams to glue anything to anything and is inexpensive. I am not sure how it will fare with all the acid vapor in your case, but it may be worth a try. Make sure your surfaces are clean and roughed up with sandpaper. Thank you for all your effort getting these videos on line.
There are nice glass beakers with the handle built in. I don’t know if I could trust a epoxied handle
Will you talk about your melt dishes. Some you have comented about just for gold, unclean, ect. What is the junk from your melt dish? Why the large stack of melt dishes. Thank you for your time. Great entertainment.
An absolute thing of beauty bro. The work you Put into that is well worth the premium you are asking.
Hey Sreetips watch one of NileRed's refining videos and pay attention to his rinsing method I think you'll like it and will save you on the amount of hcl you use
good idea with the kaowool under your crucible, iv never done that, its gotta help.
Question regarding the process - rather than 92.5% silver, could you use an alloy of 50% silver, 40% copper, 5% zinc and 5% nickel?
Reason I ask is that I’d prefer to use old coins as the catalyst as they are readily available here in Australia and can often be bought for less than silver spot price.
Great to see the process.. I'm more of the looking for the raw materials... Great video.
Hello Mrs and Mr Sreetips🌷🌷
Nice clip as always 🌷
Have a nice weekend Sir.
God bless you 🌷🌷
Arne
Thanks Arne!
Man...
I have to say, this being my first video to have watched here, I have to consider the first people that ever developed these methods and how they could possibly have ever known what cocktail of dangerous chemicals to combine, in what order and under what conditions and durations, so precisely, in order to achieve these desired results. And, how did they even know what the results were supposed to be before they began their experiments?
Clearly, I didn't spend much of my attention studying in my singular chemistry class in high school... not that they would ever have covered anything like this, I would have remembered that much at least, positively.
So, if it is obvious, based on what they are and the inherent properties of each compound or element, I apologize, in advance, for having posed any uneducated questions.
Alchemy, people searching for a way to turn lead into gold, is the predecessor to modern chemistry. So I’ve been told. Today we know that the only place with pressures and temperatures high enough to fuse protons into heavier elements is in a super nova when a massive star collapses.
I wish I had the lifetime of your knowledge I probably to old to learn all these skills. I run into a lot of free pc parts and components.
I've always wondered just how many items in this guy's house say SREETIPS on them.
His wife has it tattooed multiple places on her body as well
slow and easy wins the race! Came out beautiful Sir!
Stunning results!
Sorry about my silly drunk post on the last vid , love your stuff ,keep it up please :)
No worries, take a lot more than that to get me riled up.
Interesting how the gold powder (59:45) reminds me of Moroccan blond hash (hashish).
So mesmerizing to see poured
Beautiful gold sreetips. You always do a wonderful job.
Around 35.51, you add sulfuric acid to precipitate lead that might be present. Then you add nitric till everything in the beaker is dissolved. Would the lead remain precipitated, or dissolve again with the added nitric?
Could the final crumbs have been lead?
Building my understanding of the different processes. Not doubting yours, only trying to understand fully.
Lead sulfate will not redissolve in nitric. Im merely adding the sulfuric just in case any lead might have made it that far into the process even though this is highly unlikely. I learned this from on old refiner. He taught me to add just a little sulfuric every time I dissolve the gold whether I suspect lead to be present or not. It hurts nothing and provides a huge benefit. Lead, in just trace amounts, will ruin the ductility and malleability of the gold. Adding a few drops of sulfuric acid guarantees that all of the lead will be 100% removed during the refining.
@@sreetips Thank you. You are a excellent teacher.
Love your videos brother!
I’m going to mention that when Sreetips says that all silver must have been removed because of nitric treatments , he means all but 19% to 0%,,, Aqua Regia will dissolve and keep less than 20% by content , silver in solution,, two ways to extract that 19%or less out of solution is to evaporate solution to concentrate solution off setting the % by content or use stock pot,, but more usually rinsing well avoids this from taking place
I dont understand what you mean.
Can you bubble the reddish NO2 gas through some water to recover the nitric acid? It would cut down on air pollution and help reduce the cost of nitric acid, right?
Possibly
It would be cool to see how much silver you pull out after a refining like this, making an estimated guess based on what you started with... Love your vids as always.
Sterling/925 is theoretically 92.5% pure silver and 7.5% pure copper. But I’ve only managed to yield between 88% to 90%
I think I would probably just use distilled water for pouring the inquarted gold, and keep it in a lidded pot, and reuse it every time... I mean, even at 10x the price, it's only like $2-3 worth of water, and considering the number of runs you could do before you would need to replace it, and the amount of time it would save in the long run, it seems like it would be more time and cost effective...
I had a window AC unit. I kept a 5 gallon bucket under to catch condensate. It’d fill up in a couple days. Thought about filtering and using that for my experiments.
That 6k gold and silver alloy you are making your chess pieces with is called electrum. It was very popular in ancient times. It has a amazing look and conductive properties.
beautiful gold bar my friend excellent job 👏👏
Can you use copper wire instead of silver? Seems cheaper to do. Just asking.
Yes, but I refine silver also so it makes sense for me to use silver
@@sreetips ok. Makes sense. 👍
Where do you buy your beakers and funnels and stuff? Pretty much all the lab equipment. Fume hood is nice too!!
Ebay
Love the videos especially liked the commentary on this one
It's worth the premium just to watch these videos. Thanks!
I see gold bar i click to view and like!
@sreetips how efficient is your process? If someone drops off 100g of 14k are you getting 58g of pure gold? Do you get anything else of value out of the refining process?
Awesome videos I can’t stop watching!
you ever think of making a bar of the 6k and then running it through a metal flatterer to have thin ribbons
Great idea, then pull the silver out with boiling sulfuric acid
@sreetips at 35:01 you say that is close to three nine fine the brown gold, why not just put that into a crucible and melt? Why was it necessary to put the gold back into solution and precipitate it yet again using the stump-out?
Close to three nines is good enough for a jeweler making alloys for some new jewelry. But the only way to be sure of three nines is to refine it with a wet chemical process to get trace impurity’s out, twice.
Wow yours is way more shinier than mine!
I love all your videos but there's something about when you stamp it I like the best maybe because it's the finishing touch
I had a laugh when I heard the jingle of the RING you have installed in your house. My family recently installed a RING system, and we're a few weeks in and still getting used to the kinda annoying - but useful - noises it makes!
What happened to your gas refractory burner project? Could solve the bubbling problem.
What is the composition of the waste solution after precipitation with Sodium Metabisulfite?
Sorry ..i forget to ask you.
The stump out. What is that powder use for.? I know well you use it in gold refining.
Arne
Arne, it’s used to disinfect containers in wine making. But the actual “Stump Out” by BONIDE that you see frequently in my videos, is specifically for dissolving tree stumps. The directions say to pour it directly on the tree stump that you want removed, and in time it will eat the stump away. Instead of having to grind it out of the ground, theoretically, you can dissolve it out of the ground. I don’t know how effective it is. I’ve never tried using “Stump Out” on a tree stump.
@@sreetipsThank you Sir.
I have try to Google that but now i know for shore 🔥
If aqua regia was made 4:1 and the nitrogen was not evaporated out of the solution before the precipitation phase, how can you get the nitric acid out? Do you just boil with no additives until you get that yellowish color or do i need to add something to get the nitric acid removed?
You can rid the gold solution of excess nitric by evaporation to a syrup, then rehydrating with HCl. Repeat until no more brown fumes evolve upon adding HCl. I’ve done it, it’s time consuming but it works. Or you can add sulfamic acid. But make sure lots of extra space because it will foam over
Wow Love Gold & Diamonds :-)
can minerals be precipitated from hot geothermal spring water?
It’s probably parts per million, or parts per hundred thousand. Either way, that’s a tiny amount to try to recover.
how much does it cost to even acquire all that refining tools and chemicals.
I never kept track. I just accumulated as I went over the last ten years. Bought all my glassware on eBay.
cody's lab explains in detail using minecraft what adding silver to the gold does and how does it work...
I’ve seen it. It’s a great video. Anyone who still doesn’t understand inquartation should watch that video
I wanna see this guy precipitate gold in that 10 gallon jug. Like 1000 ounces in the jug. That would be awesome.
34:48 That's some very expensive milk chocolate right there.
you need to put your website in the description
Great video, if you added white gold in with the original melt would this still consist of the same process?
Yes, 14k white gold has the same exact amount of gold in it that 14k yellow gold has. For white gold they increase the amount of white metals, palladium, nickel, silver and/or zinc and reduce the amount of copper. For yellow gold the amount of copper is increased and the proportion of white metals is decreased. But both have the same amount of yellow gold in them.
sreetips fantastic thanks for prompt response. Keep up the great videos
Is there a constant for Gold Filled scrap? Or is it already below 25% and can be nitric boiled as is. Thanks 👍🏼
Gold filled refining and karat scrap refining are two totally different processes. There’s no constant for GF
have you ever tried to collect those nitric fumes by bubbling it through distilled water and create dilute nitric acid for your used solution phase?
I have not
You earned my sub today sir.
I have a question at 36:00 you added sulfuric acid and then a minute later you called it nitric acid, was that a mistake or is there a difference if someone uses either or in that process? Thank you
I added sulfuric to remove any lead that may be present. It combines with any dissolved lead to form lead sulfate then it can be filtered out to remove 100% of the lead from the gold.
@@sreetips thank you so much
Gold water with ice looks refreshing XD
Another quality video :)
Man that would be cool as hell for a chess set!!!!
I think the reason why sreetips doesn't use the handle is because the handle is being held on by a corroded metal strap that may break loose at any minute.He doesn't want silver all over his floor. My coffee pot I use no longer has a handle on it because it had a metal band on it and broke off after the second or 3rd time I used it. Nitric acid is a very corrosive chemical.
Quite correct. The handles should be removed
