Whew I was starting to worry that you were never going to be doing gold and silver again I like the PGM but love the gold and silver recovery well done sir thank you for sharing five stars
Mr.I cannot tell yet how wonderful this video is I’ve been looking for this kind of breakdown of scrap and definitions for a long time thank you so much
As a watch collector, that timepiece massacre was difficult to watch. But otherwise, thanks for presenting us another fantastic gold recovery journey!! Cheers!!
Indeed. Depending on the year of manufacture for the Waltham/Dueber, it's worth between US$250->US$1400 ... not sure the scrap value is -higher- than the antique value when repaired, frankly. I couldn't identify it from just the serifed face font though.
I personally enjoy watching the silver cement out when I do it as well. The different vivid colors during to refining of precious metals is amazing to see with one's own eyes. Cool stuff Sreetips.
You’re welcome! Another excellent look into your small scale operation with big time purpose. The steam cleaning shot with the tea strainer reminded me of a Star Wars scene and the copper pipe in the electrolyte looked like the final boss scene from TRON (just needed to toss the watch gears and components into frame as the finale). I suppose that makes you the Jedi or User of the story….it must be the weekend. On that note, you have a good one. Thank you Sir! 👍👍🤟
That watch was A antique. Glad you at least saved the movement. That's a very nice Waltham watch that was produced in 1906. That is out of the way I enjoy your content. :)
When I attended a gun manufacturing course when I was young, we prepared the parts for blacking(parkerizing?) by lowering them into a half barrel of boiling water. The barrel had a wall that separated the dirty and clean side, idea was to lower the parts in on the dirty side, hot water washes the oils off them and oil floats to the surface. After a while, part basket is pulled to the clean side with clean hooks underwater and lifted up, given a brief moment for residual heat to steam the parts dry and then moved into blackening bath, and from there to motor oil bath. Blackening came out perfect every time.
Great video my Brother Chief, glad you guys are doing well, These Reactions are amazing to see metals turned to liquid, then back to pure Gold with Fire and other chemicals, you are very skilled
Sreetips, you need your own Discovery Science series... or Discovery should start a Gold Rush channel and have you, Mbmmllc, Dan Hurd and all other smelters, prospectors refiners and hobbyists.
Reading some of the comments about destroying watch cases. Folks would not want to come to my shop. I'm probably going to hell for the amount of history i have destroyed! 😂😂😂
It's not the history, honestly. It's just that some watches _are_ worth a lot more at auction than the intrinsic gold/silver value... and not by a little bit. That 1881 was probably worth 100-200x the value of the gold recovered.
@@MartinBogomolni I don't get to make the judgement call. When a client send me materials i can't view it from any angle except I'm there for the gold. I do a quick once over for any problematic materials and into the acid it goes. I once destroyed a gold mask from the 1500's just for the gold it contains. The client wanted it destroyed because they claimed it was cursed and wished to take the gold to make a object to give to their enemies. I shit you not !
Hey Sreetips, do you see any value in cutting the scrap into smaller pieces to speed up or increase the efficiency of the nitric acid boils? Perhaps expose more base metal surface area to the boils. Just a thought. Keep up the great work Chief!
You are amazingly patient and meticulous. You are highly confident with very strong acids. Have you ever considered working with potassium or sodium cyanide? In this case, you started with 700+g of starting material, worked it up to get roughly 30g of very good gold. The material that makes up the major volume of that 700g is going to be Fe, Zn and Cu. You’re also going to have Ag, Pb, Sn, and Ni and act. perhaps Pt and Rh, also. If you simply hung the whole cleaned mass in an alkaline cyanide solution, it’d selectively take off the plated materials, leaving the valueless material behind. You rinse the pregnant solution into its own beaker, pour in enough bleach to oxidize the CN. At that point, you work up the solution as you normally would. You’d eliminate things like Pb, Sn, Cr from making it into your work/waste stream. You wouldn’t need to deal with magnets and you wouldn’t need to consume all 700g into solution with HNO3, HCl and H2SO4. I mean, even after acid digestion, you had stainless pieces make it nearly all the way to the end…
My friend’s dad used cyanide. He did it out back of their jewelry repair shop. He told me once that the wind shifted and some of the cyanide got into the shop. Immediately his lips and tongue swole up and he watched a fly drop dead out of the air in front of him mid-flight. None of the refiners I learned from used cyanide. It’s too dangerous.
@@sreetips Wow... I was a chemist in an electroplating shop that used NaCN by the two hundred pound barrel. I never saw anything like that. And, yeah, we used HNO3, H2SO4 and HCl in concentrated forms, just not anywhere near the alkaline cyanide baths. I guess its your comfort level and care with working with any acid, base or metal. I guess familiarity breeds comfort. Been out of it a couple decades now, and I can honestly say, I miss the smell of a plating shop... Anyway, its an alternate route that minimizes dealing with the bulk of your material and only, really, collects the metals of interest, and reduces your handling of the bulk base metal. Its, also, not anywhere as dramatic as an HNO3 boil. It's slow. Soak the articles in an alkaline cyanide bath for a couple days, kill the CN with bleach, then work it up with your acid processes. Big volume gold and silver mining is done with ball mills that produce a mountain of talcum sized rock dust that has CN percolated through it to collect all the metal in the ore body. Heap leaching is simple and cheap. You'd just be doing it on a very small scale. Thank you for what you're doing. You have the courage and gumption to actually go out and do this stuff.
Another fine video Mr. Sreetips. I have not been too well recently and I find your videos help me to relax when I am in hospital because as you can imagine there is not much to do there so any content you create is appreciated. I'm sure the nurses think I am weird when they see me watching a refining video as most of the other patients are watching films and football 🤣
Yay I'm one of the first 100. XD keep up the hard work and awesome content m8. Love watching your videos because I love the way you experiment with different ways to refine your precious metals
It seems like you could benefit from a small hammer mill. That way it would turn all that into small particles making it easier to get to the base metal.
This is much better than PMG. What do you do with the cemented silver? Why don't you use it to enquart (instead of silverware)? Can you enquart with copper? I was thinking you could use a big coffee filter and put the flat filter paper inside it so prevent the mud from leaking out.
Cement silver gets melted into shot and run through my silver cell. Inquarting with cement silver is not recommended. Palladium follows the silver. Palladium will tend to build up in the cement silver if it’s used to inquart. I must dissolve the silverware anyway so why not use it to inquart? Yes, clean copper can be used for inquartation.
@26:35 When I was a kid riding with my family through Detroit I used to see that color of vapor coming out of smokestacks all along I-75. Not so much of that any more, thank goodness.
Hey sreetips! Big fan form Norway here 😊 i ones saw a video of this ultrasonic Washing machin. They dipped a goldring that seems clean in to the water and a cloud of dirt came out. Would you to make a shorts video of that? 😊
I'd ask Marshall over at Wristwatch Revival if he wants that movement. Also, the 'glass' on the movement is called "the crystal" in watchmakers' terms :-)
Dear sreetips, I look forward to yours videos as someone starting of my journey in refining, a couple of questions watching your past videos. 1. Why do you add water during the nitric boils given the nitric is already close to 30% diluted (after inquatation). 2. After precipitating the gold using sodium metabisulphite you rinse the gold with distilled water and hydro chloric acid. I fail to understand the reason for the same especially rinsing with hydrochloric acid.
1 - adding water provides a medium for the metals to dissolve into. 2 - hydrochloric acid will rinse dissolved metals off the gold powder better than plain water.
Please Please Sreetips , try to find or make something stronger than the tiny piece of plastic that can easily break , watching the way it bends when filling , and , the way you tip the weight while setting it in the fume hood , literally scares me . I love this channel and I would hate for anything like a failure in hardware , as we all know , acids are nasty , and they don't play well with others . As always I look forward to your refining videos . Great looking material for it . Cheers
The plastic support holding the Sep Funnel is a spammer wrench for a water softener. It’s tough as nails and the perfect inside dia for the funnel. I can’t use metal parts in the presence of those fumes.
@@sreetips I fully understand what you're saying. But it's just the thin plastic tubing that I'm referring to . Thank you for your reply sir , I appreciate it and I will see you soon. Cheers
@sreetips just in case the message got lost with my grousing about the watch... I _love_ watching you go through the refining process, and I never miss a video if I can help it. I've learned a lot about recovering precious metals, and as I continue to collect metal from my various repairs, I have been experimenting and learning as well. Eventually, it's my goal to take the ~200lbs of gold, silver, and other scrap I have and run it all through to see how much precious metal can be recovered.
Martin, when you do, the best advice I have: start with small batches and work your way to bigger batches until you get the hang of it. Also, get a fume hood. No way to safely do reactions without one.
Would it be bad to melt the foils into shot before refining? I was thinking a lot of junk might be removed in the borax. Probably just a waste of time though, it works fine just incinerating them.
I recently watched an older video of yours on GF scrap and someone suggested to inquart it. I was wondering (as a non-refiner, but audience member) if that were possible, that based on estimates of yield from GF scrap refinings and past yield data to do inquartation. Would be easier if possible. Anyway, I enjoy your videos!
Inquarting the GF material wouldn’t work well. The gold content, being only about three percent, is too low. However, the GF material could be used to inquart karat gold.
@@sreetips that's what I was thinking. Instead of going through the long process of refining GF scrap and dealing with gold mud, foils that can get all over the place and lots of time for the acid to attack it. Granted, I know you refine silver so I guess that makes more sense to do that with karat gold.
Question. When a precious metal is in a liquid form.. can a person take that and stick it in blast furnace.. and would it leave all the metals if you did that? Not going to try it. I was just wondering of the versatility of the metals and if the methods were interchangeable with one another.
To some extent yes! The foils are karat gold and if you removed all the silver and base metsls it would be a fine mud and hard to filter and deal with.
Love your channel. Question for you. You are referring to these pieces as "Gold Filled"... Would it be proper to assume you are referring to Gold Plated for these parts? Gold Filled makes it sound as if these "Gold" parts have been plated with other metals and the Gold is actually the structural metal making the form. I can see copper or aluminum being used then plated with the gold, but not the other was around. That is why I am asking. And... by all means keep it up love watching the process.
When I first started twelve years ago, I couldn’t get it fast enough. I actually went to retail stores and bought gold jewelry off the shelf at Walmart so I could have the karat gold to refine it. I was that smitten with it. But as time passed, I began to accumulate the scrap jewelry. Now it seems like I’m drowning in it.
@@sreetips You kept her works, so I'll be Ok. I also noticed in the boil it was a monogramed case so little else to do with it really. Pocket watches are my life though, something I got from my late father. and that Waltham if I got a good look at it's serial would have been made 1881 so I'd keep that crystal with it, those glass ones are hard to find.
@@sreetips I second the pain I saw seeing that Waltham melted down. Despite the monogrammed case, I honestly think it had more auction value than gold base metal value. $150 on the low end right now, and the gold was worth somewhere between $4-6 if it was 0.1g? Ow.
Sound vibrations in a hot soap solution loosens and wiggles the junk off the metal. About a hundred bucks. Mine is a two liter capacity. I use about 1 part Mr clean liquid soap in 10 parts distilled water for the fluid.
Sure, with a big enough centrifuge. Better, he could simply have let it settle, poured the clear top of the solution through the filter first, then rinsed the sludge into the filter with far less liquid to pull through. Streetips knows that, so he probably did it this way so that he could get on with the acid boils right away. Then it surprised him by taking so long that the filtration still wasn't done when he needed the funnel again. That's why we got the interlude with the cementing silver.
Whew I was starting to worry that you were never going to be doing gold and silver again I like the PGM but love the gold and silver recovery well done sir thank you for sharing five stars

@@MartinBogomolni If I caught the serial number correctly the production year on the works was 1881

I personally enjoy watching the silver cement out when I do it as well. The different vivid colors during to refining of precious metals is amazing to see with one's own eyes. Cool stuff Sreetips.
I like the orange brown of NO2 contrasted against the vivid blue copper nitrate solution, very pretty... and deadly.
Me too. Watching nitric acid eat tin is also weirdly satisfying
Perfect timing

Before silver cementing, a second round of filtering might have gotten some more gold to get drawn out of the suspension.
Why not chop all the pieces of GF scrap before adding acid? Seems like more surface area of exposed base metal would allow for quicker refining.

Welcome back
I recently watched an older video of yours on GF scrap and someone suggested to inquart it. I was wondering (as a non-refiner, but audience member) if that were possible, that based on estimates of yield from GF scrap refinings and past yield data to do inquartation. Would be easier if possible.

Incredible reaction! ❓ Does the cementing make the copper thinner how many uses do you get out of a copper cut off
Yes, the copper goes into solution as the silver comes out of solution. The two metals trade places.
Question. When a precious metal is in a liquid form.. can a person take that and stick it in blast furnace.. and would it leave all the metals if you did that?
Not going to try it. I was just wondering of the versatility of the metals and if the methods were interchangeable with one another.
I don’t think it would reduce to a metal from a liquid (some of it might). But there would be loss of the gold if I tried it. My opinion.
Wondering: do these nitric boils remove the silver and base metals from the foils themselves?
To some extent yes! The foils are karat gold and if you removed all the silver and base metsls it would be a fine mud and hard to filter and deal with.
Muito bom. Gosto dos seus vídeos. Qual o nome do livro que utiliza ?
Gets notification sreetips has a new vid out. Sees it's 49 min long. X-mas has come early!!!
After this first recovery is aqua regia (nitric and hydrochloric), then precipitate with SMB, then more nitric boiling, repeat 2-3 more times?
You’ll see in part two - working on it right now.
Excellent.
So zen.
Wondering if the burning step just adds soot?
An interesting idea. Of course, when he incinerates dirtier scrap with the torch you can actually see the fumes from oils being burned off.
Nice
Wouldn't a more accurate description of "gold filled" be "billet filled with thick gold plating?"
Sounds reasonable.
Is it possible to just melt the whole piece of jewelry and have gold inquarted with brass? Would the refining process be the same?
Melting the scrap would make recovery difficult.
I kept wondering why you had a referee whistle on your desk, then I realized it was a loop.
I noticed the new cardboard in the fume hood. Do you process that with your paper storage ?
Only if I spill something
Evening Sreetips! Do you use distilled water in the steamer?
Yes! Tap water would form scale on the heating elements.
Sreetips for president!
Love your channel. Question for you. You are referring to these pieces as "Gold Filled"... Would it be proper to assume you are referring to Gold Plated for these parts? Gold Filled makes it sound as if these "Gold" parts have been plated with other metals and the Gold is actually the structural metal making the form. I can see copper or aluminum being used then plated with the gold, but not the other was around. That is why I am asking. And... by all means keep it up love watching the process.
Gold filled is a thick coating of karat gold over brass. Gold plated is just a few microns of gold over junk metal - almost nothing.
Sreetips does it take long to acquire the gold and silver scrap and jewelry that you use in your refining sessions?
When I first started twelve years ago, I couldn’t get it fast enough. I actually went to retail stores and bought gold jewelry off the shelf at Walmart so I could have the karat gold to refine it. I was that smitten with it. But as time passed, I began to accumulate the scrap jewelry. Now it seems like I’m drowning in it.
What would happen if you cut the bands laterally? Seems like the caps should just drop off a lot faster than picking at them one by one?
The caps are gold filled. The rest is stainless steel
@@sreetips my read is that if you cut lengthwise you'll get a ton of pieces as it falls apart, then you can magnet out the steel?

Pocket watches are my life though, something I got from my late father. and that Waltham if I got a good look at it's serial would have been made 1881 so I'd keep that crystal with it, those glass ones are hard to find.
I have boxes of watch movements. But I sold most of the large movements to a local watch repair guy.
@@sreetips I second the pain I saw seeing that Waltham melted down. Despite the monogrammed case, I honestly think it had more auction value than gold base metal value. $150 on the low end right now, and the gold was worth somewhere between $4-6 if it was 0.1g? Ow.
Hi sreetips! How dos the ultrasonic cleaner works? Are those expensive?
Sound vibrations in a hot soap solution loosens and wiggles the junk off the metal. About a hundred bucks. Mine is a two liter capacity. I use about 1 part Mr clean liquid soap in 10 parts distilled water for the fluid.
Hi, did you neutralise the nitric acid with eureka before you put the copper rod to recover the gold
No
Considering the price of nitric acid versus yield, would it not be better to use Sulfuric acid for this?
Possibly. Just take a little longer.
What happens if you don’t burn it before resolving in chemical?
The yield and purity tend to be reduced.
Could you put the slugey solution in a centrifuge separate the purple gold sludge out which might prevent the clogged filters?
Sure, with a big enough centrifuge. Better, he could simply have let it settle, poured the clear top of the solution through the filter first, then rinsed the sludge into the filter with far less liquid to pull through. Streetips knows that, so he probably did it this way so that he could get on with the acid boils right away. Then it surprised him by taking so long that the filtration still wasn't done when he needed the funnel again. That's why we got the interlude with the cementing silver.
Yes
Could you add a neodymium magnet to a long thin test tube and use it as a stir rod to remove any steel?
Possibly
I may have missed , but is there a formula for how much acid for the amount of gold / base metal , ratio ?
Thanks again
Roughly 3ml nitric per gram of GF scrap is a good rule of thumb
