I’m sure this is a question you’ve seen before, but given the many years you’ve spent refining, how many ounces…ballpark…have you recovered/refined? I truly find this fascinating and you do a great job presenting it, particularly in a manner that provides detail and explanation in every video. That’s great for anyone who might randomly come across one of your videos. There’s no presumed understanding, just good consistent explanation of your methods. Very well done.
@rcgusto2427 it's really hard to say, because (imo) much more than a nonzero amount of gold ends up in the waste liquids, as has been clearly demonstrated many times in past videos, mainly the silver cell filter recover videos but also in others. frankly i don't think stannis testing is 100% accurate because some of the gold seems to "follow" the copper nitrates and silver nitrates for whatever reason (my assumption is there is some sort of novel copper/silver nitrate and gold amalgum in solution thing going on, which the stannis chloride can't detect because it's not just straight up gold in solution)
@@gfhrtshergheghegewgewgew1730 Stannous chloride is a sensitive test, but small amounts of gold inevitably get carried around, and some tiny amount could pass through the filters as well. That accumulates. Heck, just notice how many times he can harvest his silver cells before the filter baskets get slimed up, and how little gold he recovers from a dozen or so filters. He's losing like 0.001% or something so close to 0 that if he wasn't doing this in a continual process, he'd just write off the tenth of a penny worth of gold
I’ve been watching your videos for at least 5 years now, Mr Sreetips. I’ve also read C M Hoke’s book and signed up on GRF. I’ve internalized most of the basic processes for gold and silver refining and I feel confident that with the correct setup, I would hit the ground running. However, I’m not delusional and it seems like precious metal refining for hobbyists is fraught with obstacles not only on the chemical reactions level. The hunting and purchasing of plated, gold filled and karat scraps at a good price (one that will eliminate loss of profit) appears to be the most tricky part of the operation. Hats off to Mrs Sreetips! I feel as a beginner I would necessarily get burned quite often initially 😂 keep doing what you do Sir. We love tour videos ❤
Would love to see a video with a general breakdown of costs / amounts used in your refining for chemicals, filters, time etc. Anyway, most valuable "scrap" I've ever seen!!!
You are welcome. Nice recovery! Another 1/2ozt+ rescued! Looking forward to seeing the test results from the undissolved material in an upcoming broadcast. Thank you Sir!👍👍🤟
I have a beautiful Swiss Bulova manual wind wristwatch in a rolled gold case. Probably 1950s. No you can't scrap it, it keeps excellent time. Always enjoy your videos
I love watching u refining gold because u explain it so amazing well, because we learn alot from listening to u, what a fantastic and awesome job 👍 👌 👏
If you get lucky with what you find, OLD style GF stuff can be very lucrative. If you see stuff that's more modern... then you can end up screwed. A lot of modern stuff called GF is no different than heavy electroplate.
I was at one of my local buyers and a lady was in there with a ton of costume jewelry. He doesn't buy filled scrap so I took a look. I bought 2 large sandwich bags(crammed full) of stuff for $40. Turns out after looking better at home a ring and 3 sets of ear rings were carat gold. I sold the stuff and a dozen silver eagles to another local buyer for a tremendous profit.
I was picking a mega pawn store when I spotted Karat plus set diamond for 1300. It was filthy dirty but I was able to grade it with my loupe. Feeling the rush I mumbled to the broker that I've only got 900 cash. Three hours later 3500.00😊
My wife made me shut down my shop right in the middle of a project to take her to a yard sale on a Thursday morning. I wasn’t very happy. When I got there the lady said, “you’re my first customer.” My eyes locked on to two GOLD bracelets. Thick chunky ones. I asked what she wanted for them. She said, “ten for the small one, and fifteen for the big one. I know they’re supposed to be pure gold, but I don’t want them, I just need them gone along with all this other stuff.” It was over $1800 in gold, back when it was down around $1400 per ounce. It’s out there. But it won’t just fall in your lap. By the way, I’ve still got those pieces. And now they’re worth around three grand. There’s no way that I would ever dream of converting that gold, that’s rising, into paper for a “profit”. Converting gold into paper is just plain madness. Converting paper into gold, is just plain smart.
They had a big brick house and lots of currency stacked up. To them, the gold wasn’t worth anything. Nothing more than something to get rid of. People are CLUELESS about gold and silver. But for those who know the truth, this lack of understanding yields some fantastic opportunities to accumulate real wealth: gold and silver.
Awesome video, yet again. I learned what gold filled jewelry is, now I can look for it. I would love to see you do some electronics refining, such as IC & flat chips, memory sticks, capacitors, etc. Keep up the great work!
You’ll notice a good amount of rhodium when refining larger batches of Victorian era gold filled. Rhodium was a cheaper metal that was almost considered waste during that era, and was commonly used as plating over the copper prior to the gold being placed over it. If you’re lucky based off the material, During the AR process, you’ll notice chrome flakes that won’t go into solution as easily. Some may make it into solution, but is obviously recovered in the stock pot later. Save your filter papers for the gold filled separate if you can, other than some potential silver chloride and lead sulphate, it’ll be relatively easy to recover after saving the filters and doing a big incineration day with them to process. 😊
when pouring the gold into your graphite mold the moment you have it poured tap the side of the mold while the map gas touch is still on until the gold sets ...you may get much lovelier ripping effects
Oh man, I love gold so much! I just think it's so amazing and cool how you can take solid gold, turn it into a liquid then a powder and then back to a solid! I wish I can play with some gold sponge and turn it into a solid! One day Sreetips....one day..😂
I did my 1st refining about 10 months ago and bought a bottle of Loudwolf Stannous Chloride. I did my 2nd refining last week and decided to make my own Stannous Chloride to my surprise the 10 month old Stannous Chloride was still good.
The joys of going to flee markets or other sales, most of the time they have an idea of what they are selling, but way undervalued. Sometimes they sell things for pennies on the dollar with no idea of what they are selling.
Yeah but many times you get yahoos that think their karat gold is worth pure gold prices. Many have no idea though. I've had folks argue with me even when I show them how it works. I have no time for negativity anymore. Just take my worthless paper for your gold
Excellent video as usual. I would however have poured off the solution after the initial 500 ml of nitric to remove the base metals, lowering their concentration in the next cycle (driving the equilibrium to the right).
@@sreetips Never said my way was the only one. And it has taken me watching your videos for a while in combination with my past education to see/notice minor possible improvements, which in the end don't change the outcome. NB: As I wrote, I would have poured it off for the reason stated, but rinsing would add a lot of extra work without much benefit. Keep up the good work, looking forward to your next video. And while I am at it, how is the build-up of lead in the filter papers? You always remove it with sulfuric acid and it gets filtered out. However, every time you process those old paper filters, there will be more lead in it.
Just out of curiosity. Would you have been able to melt all the scrap down, pour it into shot and then proceed with the nitric? Not sure if that would yield the same or worse results.
Love your videos. They are fascinating (and relaxing) to watch. Is it possible to do a side by side of different gold refining techniques for a future video please 🙏? Questions I do have are: Why is HNO3 added to HCI but never the other way around? How do you determine the amount/ratio of Aqua Regia v's the amount of scrap you are trying to process? What happens to your waste solutions once you recover gold/silver. Is there someone out there that recovers the copper with your waste?
Excess hcl is never a problem. Excess nitric causes big problems. By adding hcl first I can carefully control the amount of nitric going into the reaction.
I can dissolve an ounce of gold with 150ml of HCl and 15 to 18ml nitric acid. I use the expected (estimated) yield to judge how much of each acid to add.
Waste treatment for my gold and silver waste solutions. Clean copper for refining is cheap and plentiful. After it’s used, it becomes waste because it would cost more to try to recover and reuse it than just buying clean copper.
Salutations Mr Sreetips, I hope all is well with you and the missus. I ran across a metal the other day that stands up to all the gold test acids, has a sort of copperish or sightly rose gold look, is magnetic but not vigorously so to a neodymium magnet, is a bit springy, and not overly heavy or light. I eas thinking stainless, but cant recall ever seeing it in that color. Any ideas?
How does the nitric get to the base metal under that thick of a gold coat? Would it have been easier to refine by melting the jewelry and inquarting then extracting? Seems like this uses alot of nitric?
Alloy 16 grams of gold with over a pound of brass? That would make recovering the gold more difficult. The nitric always finds a way to penetrate to the base metals. Believe me, this is the easier and softer way. Getting pure gold, from any source, is never quick, easy, or cheap.
Just a couple of noob questions…. Wouldn’t cutting the scrap up into smaller pieces increase surface area and therefore induce a faster reaction? Also I know that there are Pyrex magnetic stirring rods - would that also help decrease production time? Appreciate your videos!
Found this on the net. Also what would happen if you poured the diluted gold concentrate into diluted SMB? EPNS-If someone is trying to sell you a piece of “gold” marked “EPNS,” run away. It stands for “Electroplated Nickel Silver,” which is silverplate. This means the piece is not gold, and it’s worthless. EPBM-Again, if someone is trying to sell you “gold” marked “EPBM,” go elsewhere. This stands for “Electroplated Britannia Metal,” which is not gold at all. It is a silver/tin alloy consisting of copper, lead, or zinc. GE-Gold Electroplate is a piece consisting of a base metal, often brass, with a certain thickness of gold electrolytically deposited onto the base. The minimum standards require to be considered GE is 7 millionths of an inch and at least 10K gold as the plating. HGE-This also refers to Heavy Gold Electroplate, the same as GE above, but it can only make the "heavy" classification if the plating is at least 100 millionths of an inch. GF-This means "gold filled" and is like gold plate but the gold is heat- and pressure-bonded to the base metal. It must have a minimum purity of 10K gold and the gold content must be at least 1/20th of the weight of the metal piece. 375-This means the gold is 37.5% pure, or 9K. In the US, the minimum standard for gold is 10K. Many other countries allow marketing this as gold and it’s been used in both jewelry and dental applications. 417-This means that the gold is 41.7% pure, or 10K. In the US, jewelers uses this purity because it is very strong. It is great for jewelry for those who work industrious jobs or who need something that will hold up. 585-This means that the gold is 58.5% pure, or 14K. Good, strong gold but with more gold than 10K. 750-This means that the gold is 75.0% pure, or 18K. Much more pure than 14K, still has good strength with a wonderful balance in purity. 916-This means that the gold is 91.6% pure, or 22K. This is probably the softest and most pure gold you would want to have for a piece of jewelry. 999-This means the gold is 99.9% pure, or 24K. This is the purest that you can buy, and although purity can be up to six nines fine, or 999.999, it’s highly rare to find it so pure. Such fineness in gold was last refined in the 1950s by the Perth Mint in Australia.-
Hello! I love your channel and I’ve watched several videos more than once. I have a couple of questions. 1. How does the nitric acid remove the silver and base metals from 14k gold filled material without being inquarted? Doesn’t it have to be 6k? Does it have to be alloyed or is being a thin sheet good enough? Obviously what you’re doing works, I’m just confused. 2. I know you said that copper isn’t worth refining financially but have you ever considered refining a small amount for a video? I would be interested in seeing that. Thank you so much for this channel. I never would have guessed that people refine gold and silver as a hobby or that I would be so fascinated by it.
I didn’t think people would be that much into it either. After all, GOLD is nothing more than a barbarous relic, antiquated, outdated. But i just at got done reading the Bible cover to cover. Gold and silver (as real wealth) are mentioned over two hundred times. Not one reference to Apple, Amazon, US dollar, or bitcoin. What this means to me is that long after all those are gone and forgotten, gold (and silver) will still be here. And they’ll still be valuable.
I wonder if a nitric acid boil would be somewhat useful. like removing traces of other metals. The liquid was green which makes me think there might be some copper in it with the gold.
So you got about a half troy ounce of gold from that refining, from 491g of gold-filled material. That goes about $1,200, but what was the investment of getting that material? I know Mrs. Sreetips is skilled as well as beautiful, but I'm sure there was some investment cost. Given that, was it still worth it to refine it?
We get gold filled material for a fraction of the gold value. Some of it comes in junk jewelry lots. People think it’s worthless, like costume jewelry. I just save it up until I have enough for a batch.
If you don’t know what you’re doing, you’ll end up paying for karat gold instead of gold filled😂 “don’t ask me how I know.” 😂 I’ve done several ways of processing. One was putting it in a/p for a month. Then taking my foils set aside. Put a solid copper ingot in the ap until it cements. Combine the foils, and the cement, popcorn and process as karat scrap. Pain I. The butt, but less nitric. I tried melting the gold filled and pouring into shot, and process. That worked the best. I tried processing like you do, don’t have the separator funnel, but learned not to add too much nitric 😮. Yup it boiled over.
That homemade separatory funnel contraption looks scary when setting it in the vent hood.. That much nitric accidentally tipping over is some scary shi...
I agree, personally I would put the heater on the foot with the funnel over the foot (and heater and beaker). That way it is a lot more stable while also taking less space.
A quick question. On gold filled watch bands do you pull the individual front plates off? If so, what is the most efficient way of doing so? Thank you.
Several of my GF watch bands have SS backs will the nitric be able to dissolve them as well? Do you concern over small stones or enamel? and I viewed your Pleeted Filter setup and thats a qualitative type?
I remove all the stainless steel before going to the acid. Nitric acid is sometimes stored in stainless steel kegs. So I’m pretty sure it won’t dissolve the stainless.
Best to remove before processing, but I’ve left stones and enamel in and filter it out later on. The pleated filter was a number two medium flow. And that’s all I know about it.
@@sreetips I had noticed it didn't look all that hard to bend over the little tabs with a small screw driver to release the GF top from the Stainless steel bottoms. I had originally thought of this to save on resource materials thinking it would take less Nitric.
@@sreetips The step where you place the filter papers in the over to burn off all combustible material, Could I do that same step in my Forge in a tall Crucible??
It is rather confusing when they call it "Gold Filled". One would think it was Filled with Gold. Not true. They should call it Brass filled, because it's Gold filled with Brass.
After the gold foils were filtered and incinerated, you went directly to aqua regia. what would happen if a piranha solution were used to consume all of the carbon deposits before the nitric acid was used?
intense video as always, torch flames, incinerations, into solution, out of solution, boiling acids, precipitations,,,, you didn't mention if this bar was for sale,
No, I’m not selling at the grossly undervalued spot price. And folks get angry when I ask $3k (closer to its true value) so I’ll just keep it. One of my mentors used to say that when dealing with GF scrap, the three most important things to remember are: incineration, incineration, and incineration.
This makes me wonder how testing solutions are designed. I get that they're mixes of nitric acid and hydrochloric acid, but how do they alter the composition to make them able to test different purities of gold? Do they just dilute the mix with water so that it won't react on lower purities? Or is it just by adding or removing a percentage of the nitric acid? Making testing solutions could be a good little side business when you look at their margins, although selling acid might not be worth it because of the risk of litigations.
On the goldrefiningforum.com there’s a thread on there that gives the recipes for the various concentrations to make all the different testing solutions.
Other than the recycled CPU parts video, I think this is the first time I've seen you NOT melt & enquart. Is that because this is rolled & the other was solid gold?
i would really be interested in how much silver you would yield from 500 grams of gold filled scrap. i know you add it to your stock pot, but I'd love for you to precipitate out the silver just as an experiment. maybe you've done that before and found it wasn't enough of a yield. regardless, I'd be interested in knowing.
when refining GF I see here you drop it in slowly and in batches yet I'm sure I have seen in other videos where you add the nitric right in. What's the difference. And if you have a piece that is coated in GF Karat gold how does the Nitric penetrate to the base metals beneath? And would the steps for Vermeil be the same as regular GF?
@@sreetips Just a curiosity and wanted your input, If you melted your GF or Vermeil jewelry and then poured it slowly into your chilled water pail to make metal cornflakes then proceeded with the nitric bath would it react any different as opposed to your usual process. Could it potentially speed the process or actually impede it? As always Thank you so much
Archimedes used density and his own buoyancy law to prove that the King’s crown was NOT pure gold but rather had a cheaper fill metal inside it. Weigh the object accurately then determine its volume using a precise volume displacement method. This will give you a value for density. If its significantly less than 19.3 kg/m3 then it’s not pure gold. This is difficult to do for thin plated gold objects, but certainly an easy way to show that an object is pure gold (or greater than 5% Au at least)
@@apveening True. Although the element used in the case of densities higher than that of gold would need to be something like Osmium (22.59 kg/m3). There are only 6 elements more dense than gold and Osmium has the highest density. (Iridium 22.56, Platinum 21.46, Rhenium 21.02, Neptunium 20.45, Plutonium 19.84) All of which are unlikely to be added as a filler with exception of Platinum, which is also a very expensive metal. Most likely lighter less dense elements would be used. Great video - I hope you keep them coming.

NB: As I wrote, I would have poured it off for the reason stated, but rinsing would add a lot of extra work without much benefit.
Keep up the good work, looking forward to your next video.
And while I am at it, how is the build-up of lead in the filter papers? You always remove it with sulfuric acid and it gets filtered out. However, every time you process those old paper filters, there will be more lead in it.
Gooood evening from central Florida! Hope everyone has a great night!
Goooood evening!
My fat ass thought that was a bowl of Ramen at first 😂
Just out of curiosity. Would you have been able to melt all the scrap down, pour it into shot and then proceed with the nitric? Not sure if that would yield the same or worse results.
No, that’s not the way it’s done. Removing base metals from the scrap with nitric to recover the gold foils is the best way to do this
Love your videos. They are fascinating (and relaxing) to watch.
Is it possible to do a side by side of different gold refining techniques for a future video please 🙏?
Questions I do have are:
Why is HNO3 added to HCI but never the other way around?
How do you determine the amount/ratio of Aqua Regia v's the amount of scrap you are trying to process?
What happens to your waste solutions once you recover gold/silver. Is there someone out there that recovers the copper with your waste?
Excess hcl is never a problem. Excess nitric causes big problems. By adding hcl first I can carefully control the amount of nitric going into the reaction.
I can dissolve an ounce of gold with 150ml of HCl and 15 to 18ml nitric acid. I use the expected (estimated) yield to judge how much of each acid to add.
Waste treatment for my gold and silver waste solutions. Clean copper for refining is cheap and plentiful. After it’s used, it becomes waste because it would cost more to try to recover and reuse it than just buying clean copper.
Another great video. Why the smb dissolve and filter?
For the show, and a little variety.
As always love your videos.
Gold filled is casted or mixed where the other is wrapped maybe welded
Heyho Melt Magician MrSree how do dude hope all is well bro that shiny wee thing be worth £982.75p in the UK today nice haul dude as all ways .
Salutations Mr Sreetips, I hope all is well with you and the missus. I ran across a metal the other day that stands up to all the gold test acids, has a sort of copperish or sightly rose gold look, is magnetic but not vigorously so to a neodymium magnet, is a bit springy, and not overly heavy or light. I eas thinking stainless, but cant recall ever seeing it in that color. Any ideas?
Not without testing it myself.
Supper classy I must say
How does the nitric get to the base metal under that thick of a gold coat? Would it have been easier to refine by melting the jewelry and inquarting then extracting? Seems like this uses alot of nitric?
Alloy 16 grams of gold with over a pound of brass? That would make recovering the gold more difficult. The nitric always finds a way to penetrate to the base metals. Believe me, this is the easier and softer way. Getting pure gold, from any source, is never quick, easy, or cheap.
Just a couple of noob questions…. Wouldn’t cutting the scrap up into smaller pieces increase surface area and therefore induce a faster reaction? Also I know that there are Pyrex magnetic stirring rods - would that also help decrease production time? Appreciate your videos!
Cutting would increase surface area, but I’d rather let the chemicals do all that work. I’ve got teflon magnetic stir bars. And they would help.
Holy Smokes mr Sreetips man this is an awesome Goldbar man wow✨️✨️✨️👍💥greetings from the Netherlands sreetips 🎉
Thank you Netherlands
Found this on the net. Also what would happen if you poured the diluted gold concentrate into diluted SMB?
EPNS-If someone is trying to sell you a piece of “gold” marked “EPNS,” run away. It stands for “Electroplated Nickel Silver,” which is silverplate. This means the piece is not gold, and it’s worthless.
EPBM-Again, if someone is trying to sell you “gold” marked “EPBM,” go elsewhere. This stands for “Electroplated Britannia Metal,” which is not gold at all. It is a silver/tin alloy consisting of copper, lead, or zinc.
GE-Gold Electroplate is a piece consisting of a base metal, often brass, with a certain thickness of gold electrolytically deposited onto the base. The minimum standards require to be considered GE is 7 millionths of an inch and at least 10K gold as the plating.
HGE-This also refers to Heavy Gold Electroplate, the same as GE above, but it can only make the "heavy" classification if the plating is at least 100 millionths of an inch.
GF-This means "gold filled" and is like gold plate but the gold is heat- and pressure-bonded to the base metal. It must have a minimum purity of 10K gold and the gold content must be at least 1/20th of the weight of the metal piece.
375-This means the gold is 37.5% pure, or 9K. In the US, the minimum standard for gold is 10K. Many other countries allow marketing this as gold and it’s been used in both jewelry and dental applications.
417-This means that the gold is 41.7% pure, or 10K. In the US, jewelers uses this purity because it is very strong. It is great for jewelry for those who work industrious jobs or who need something that will hold up.
585-This means that the gold is 58.5% pure, or 14K. Good, strong gold but with more gold than 10K.
750-This means that the gold is 75.0% pure, or 18K. Much more pure than 14K, still has good strength with a wonderful balance in purity.
916-This means that the gold is 91.6% pure, or 22K. This is probably the softest and most pure gold you would want to have for a piece of jewelry.
999-This means the gold is 99.9% pure, or 24K. This is the purest that you can buy, and although purity can be up to six nines fine, or 999.999, it’s highly rare to find it so pure. Such fineness in gold was last refined in the 1950s by the Perth Mint in Australia.-
Is it worth the effort to nip all these to bits with a cutter? Or will the acid penetrate efficiently enough around the karat gold?
I’d rather let the chemicals do the work.
Hello! I love your channel and I’ve watched several videos more than once. I have a couple of questions.
1. How does the nitric acid remove the silver and base metals from 14k gold filled material without being inquarted? Doesn’t it have to be 6k? Does it have to be alloyed or is being a thin sheet good enough? Obviously what you’re doing works, I’m just confused.
2. I know you said that copper isn’t worth refining financially but have you ever considered refining a small amount for a video? I would be interested in seeing that.
Thank you so much for this channel. I never would have guessed that people refine gold and silver as a hobby or that I would be so fascinated by it.
1. Being a thin sheet is enough. The acid don’t attack to gold, only the base metal (brass).
2. I have pounds of silver sitting idle that needs to be refined. I simply don’t have time to devote to copper.
I didn’t think people would be that much into it either. After all, GOLD is nothing more than a barbarous relic, antiquated, outdated. But i just at got done reading the Bible cover to cover. Gold and silver (as real wealth) are mentioned over two hundred times. Not one reference to Apple, Amazon, US dollar, or bitcoin. What this means to me is that long after all those are gone and forgotten, gold (and silver) will still be here. And they’ll still be valuable.
😅sreeetips, your chill as shit bud 😊 keeep it up. Much love from Colorado
I wonder if a nitric acid boil would be somewhat useful. like removing traces of other metals. The liquid was green which makes me think there might be some copper in it with the gold.
I’d be concerned that a large bit of gold would go into solution if I did a nitric acid boil.
Possibly but unlikely after the nitric boils, more likely some PGMs.
I had received a destroyer from California USS BERKELEY ADAMS 1992-93 I AM A RECEIVER CREW .SIR
The Navy was good to me. And I was good to the Navy.
SAME FOR ME
How is/are the silver cell(s) doing? Haven't seen anything in awhile about them
Been busy with other stuff.
So you got about a half troy ounce of gold from that refining, from 491g of gold-filled material. That goes about $1,200, but what was the investment of getting that material? I know Mrs. Sreetips is skilled as well as beautiful, but I'm sure there was some investment cost. Given that, was it still worth it to refine it?
We get gold filled material for a fraction of the gold value. Some of it comes in junk jewelry lots. People think it’s worthless, like costume jewelry. I just save it up until I have enough for a batch.
If you don’t know what you’re doing, you’ll end up paying for karat gold instead of gold filled😂 “don’t ask me how I know.” 😂
I’ve done several ways of processing. One was putting it in a/p for a month. Then taking my foils set aside. Put a solid copper ingot in the ap until it cements. Combine the foils, and the cement, popcorn and process as karat scrap. Pain I. The butt, but less nitric.
I tried melting the gold filled and pouring into shot, and process. That worked the best.
I tried processing like you do, don’t have the separator funnel, but learned not to add too much nitric 😮. Yup it boiled over.
The ass was kicked again. Thank you Sir.
great looking bar
That homemade separatory funnel contraption looks scary when setting it in the vent hood..
That much nitric accidentally tipping over is some scary shi...
I agree, personally I would put the heater on the foot with the funnel over the foot (and heater and beaker). That way it is a lot more stable while also taking less space.
As always, really nice
Good job once again
I hope Sreetips saves some of that ice for his pina colada or whatever he likes to drink. x
Will the gold follow the vapors win ur boiling down to a syrup?
There’s probably a little gold in the form of tiny droplets that exit the braker during the boil.
A quick question. On gold filled watch bands do you pull the individual front plates off? If so, what is the most efficient way of doing so? Thank you.
Yes, I use a small wire cutter and peel each one off. Giant pain, but every little bit counts.
@@sreetips thank you for the prompt response. Been watching you for years. Decided to give it a try.
what type of filter papers are being used hear. Obviously if I was to use my flat bottom filter papers this process would get messy quick.
Please see “Preparing a Buchner Funnel Filter Paper” video posted a few weeks ago.
@@sreetips Thanks I sure will check it out.
What were you in the Navy. I'm a retired MMCS.
Same here, retired in 95
Several of my GF watch bands have SS backs will the nitric be able to dissolve them as well? Do you concern over small stones or enamel? and I viewed your Pleeted Filter setup and thats a qualitative type?
I remove all the stainless steel before going to the acid. Nitric acid is sometimes stored in stainless steel kegs. So I’m pretty sure it won’t dissolve the stainless.
Best to remove before processing, but I’ve left stones and enamel in and filter it out later on. The pleated filter was a number two medium flow. And that’s all I know about it.
@@sreetips I had noticed it didn't look all that hard to bend over the little tabs with a small screw driver to release the GF top from the Stainless steel bottoms. I had originally thought of this to save on resource materials thinking it would take less Nitric.
@@sreetips Thanks so very much
@@sreetips The step where you place the filter papers in the over to burn off all combustible material, Could I do that same step in my Forge in a tall Crucible??
Great feeling good❤
I noticed you didn't pre wet that filter like you usually always do.
That filter went up the sides.
It is rather confusing when they call it "Gold Filled". One would think it was Filled with Gold. Not true. They should call it Brass filled, because it's Gold filled with Brass.
After the gold foils were filtered and incinerated, you went directly to aqua regia. what would happen if a piranha solution were used to consume all of the carbon deposits before the nitric acid was used?
The carbon would disappear.
intense video as always, torch flames, incinerations, into solution, out of solution, boiling acids, precipitations,,,, you didn't mention if this bar was for sale,
No, I’m not selling at the grossly undervalued spot price. And folks get angry when I ask $3k (closer to its true value) so I’ll just keep it. One of my mentors used to say that when dealing with GF scrap, the three most important things to remember are: incineration, incineration, and incineration.
What is your fume hood made from? Is there filters?
Fiberglass, no filters
This makes me wonder how testing solutions are designed. I get that they're mixes of nitric acid and hydrochloric acid, but how do they alter the composition to make them able to test different purities of gold? Do they just dilute the mix with water so that it won't react on lower purities? Or is it just by adding or removing a percentage of the nitric acid? Making testing solutions could be a good little side business when you look at their margins, although selling acid might not be worth it because of the risk of litigations.
On the goldrefiningforum.com there’s a thread on there that gives the recipes for the various concentrations to make all the different testing solutions.
@@sreetips Wonderful, thank you sreetips! I'm off to find it!
Other than the recycled CPU parts video, I think this is the first time I've seen you NOT melt & enquart. Is that because this is rolled & the other was solid gold?
The gold foils are very thin and have no problem dissolving in hot Aqua Regia.
i would really be interested in how much silver you would yield from 500 grams of gold filled scrap. i know you add it to your stock pot, but I'd love for you to precipitate out the silver just as an experiment. maybe you've done that before and found it wasn't enough of a yield. regardless, I'd be interested in knowing.
I usually just add some HCl and precipitate out the silver chloride, then convert it to pure silver with lye and sugar.
Cool quick money!!! LOL
when refining GF I see here you drop it in slowly and in batches yet I'm sure I have seen in other videos where you add the nitric right in. What's the difference. And if you have a piece that is coated in GF Karat gold how does the Nitric penetrate to the base metals beneath? And would the steps for Vermeil be the same as regular GF?
Adding nitric all at once increase the risk of a boil over. Nitric always finds a way. Yes, it’s exactly the same for both GF and GP silver.
@@sreetips Just a curiosity and wanted your input, If you melted your GF or Vermeil jewelry and then poured it slowly into your chilled water pail to make metal cornflakes then proceeded with the nitric bath would it react any different as opposed to your usual process. Could it potentially speed the process or actually impede it? As always Thank you so much
Colloidal gold, making separation difficult.
@@sreetips ahh I see its easier to seperate them as just 2 parts rather than when intertwined. Thanks so much
Correct
Archimedes used density and his own buoyancy law to prove that the King’s crown was NOT pure gold but rather had a cheaper fill metal inside it.
Weigh the object accurately then determine its volume using a precise volume displacement method.
This will give you a value for density. If its significantly less than 19.3 kg/m3 then it’s not pure gold.
This is difficult to do for thin plated gold objects, but certainly an easy way to show that an object is pure gold (or greater than 5% Au at least)
"If its significantly less than 19.3 kg/m3 then it’s not pure gold."
If it is significantly more, it isn't either (but that isn't very likely).
@@apveening True. Although the element used in the case of densities higher than that of gold would need to be something like Osmium (22.59 kg/m3). There are only 6 elements more dense than gold and Osmium has the highest density.
(Iridium 22.56, Platinum 21.46, Rhenium 21.02, Neptunium 20.45, Plutonium 19.84)
All of which are unlikely to be added as a filler with exception of Platinum, which is also a very expensive metal.
Most likely lighter less dense elements would be used.
Great video - I hope you keep them coming.
Tang?
So, why do we not burn off the zinc in the furnace before dissolving with nitric acid?
Because zinc is highly soluble in nitric acid.
Stupid question here, but why in the first stage did you spoon SMB into the solution, and then in the second stage, add the SMB as a solution? 🤔😊
For the show, and to get rid of (use up) that filtered SMB solution that I had
@@sreetips Thanks! Love watching the Chemistry too. 😊
Yield was insane niiiiice
A surprise to the upside is always a pleasant surprise.
