Hey I just have to say is I’m so impressed with your thoroughly detailed steps . This is something I was lucky to be forced into doing because of a car accident that took my career as an electrician of 1 years. I immediately dumped my savings into gold for scrap recovery not knowing if I could do it. I haven’t found any steps like yours anywhere on TH-cam or on line as a good video to tutorial. I have been missing just a couple steps in my refining process that I picked up from watching this video thank you so much for your hard work and teaching in allowing us to benefit from you and your videos. I have been doing this now for about six months and gone through about 16 ounces of gold . Again thank you so much
Excelent video. The details you walk through are so important to anyone trying to learn. Thanks for sharing your knowledge in an easy to follow, complete format.
Well done sir I've been researching the refining process for sometime now.

I've sat through hundreds of videos but yours are by far the best out there the easiest and most thorough person sharing your process. Thanks for the knowledge.
Hey Sreetips, having done this myself years ago... I found that using tap water was the source of the cloudiness - because tap water and tap water ice has iron, lead, copper, tin, PVC chlorides and other impurities in it too, but I do appreciate your tenacity in creating as pure a gold concentrate as you can get.

Thank you for your positive comments. I agree with your statements. Most people believe that the dollar is still backed by gold, it's not. Also, most folks have no clue what inflation is (it's an expansion of the money supply) or where it comes from (it comes from endless money printing). It's not a question of "if" but rather "when" the shtf. It's coming. But as long as people remain confident that the dollar has value, and the Fed doesn't get out of hand with printing dollars, they can probably do it for quite some time to come. But this lul will enable those who know the truth to accumulate precious metals. But at some point, all hell will break lose.

Aqua regia dissolves gold, though neither constituent acid will do so alone, because, in combination, each acid performs a different task. Nitric acid is a powerful oxidizer, which will actually dissolve a virtually undetectable amount of gold, forming gold ions (Au3+). The hydrochloric acid provides a ready supply of chloride ions (Cl−), which react with the gold ions to produce tetrachloroaurate(III) anions, also in solution. The reaction with hydrochloric acid is an equilibrium reaction that favors formation of chloroaurate anions (AuCl4−). This results in a removal of gold ions from solution and allows further oxidation of gold to take place. The gold dissolves to become chloroauric acid. In addition, gold may be dissolved by the chlorine present in aqua regia. Appropriate equations are: Au + 3 HNO 3 + 4 HCl {\displaystyle {\ce {>}}} {\displaystyle {\ce {>}}} [AuCl 4]− + 3 [NO 2] + [H 3O]+ + 2 H 2O or Au + HNO 3 + 4 HCl {\displaystyle {\ce {>}}} {\displaystyle {\ce {>}}} [AuCl 4]− + [NO] + [H 3O]+ + H 2O If the aqua regia solution only contains gold, solid tetrachloroauric acid may be prepared by boiling off excess aqua regia, and removing residual nitric acid by repeatedly heating with hydrochloric acid. That step reduces nitric acid (see decomposition of aqua regia). If elemental gold is desired, it may be selectively reduced with sulfur dioxide, hydrazine, oxalic acid, etc.[6] The equation for the reduction of gold by sulfur dioxide is: 2 AuCl− 4 (aq) + 3 SO 2(g) + 6 H 2O (l) → 2 Au (s) + 12 H+ (aq) + 3 SO2− 4(aq) + 8 Cl− Aqua regia dissolves gold, though neither constituent acid will do so alone, because, in combination, each acid performs a different task.

👍you are awesome. The chemistry that it takes to refine gold is outstanding. I didn’t know you could take gold turn it into a liquid and bring it back. Beautiful thing!
Fantastic process as always. So satisfying to watch. Especially that melt at the end wow. I'd love to see a high speed slow motion of the meta bisulfite precipitating out the gold (plus many more reactions). Destin from Smarter every day might be willing to record that if you send him an email. That would be cool.
Ah perfect! I recently picked up a large collection of gold filled ladies watches and was planning on refining them! this will be a great refresher for me!
sreetips, love watching your videos. haven't been on the forum in ages... but still just enjoy how thoroughly and methodically you explain everything to the viewers! haven't added the lab to my new house yet so haven't refined anything in the last couple years... looking forward to starting it again!
a nice bite of work 😋 to clean up that gold that was impressive thank you for sharing the process and the time it took. i see where patients is a valuable component of this and you got a good payment for your efforts. thank you for sharing your time and information on this 😊
That's a LOT of work over MANY days... for $900. Not sure it is worth it, especially when you add in the cost of the chemicals and glassware. But if you are happy doing it, then have fun!
I sell my gold to Elemetal Direct. They pay 98% of spot. This bar sold under that but I don't care. I'm trying to promote my social media presence. I've got some more gold coming up in future videos. Eventually the bars will start to bring a premium. But for now I have to pay my dues and let the chips fall where they may.
I watched the whole video, looked at the 2018 selling and value price then calculated the today price $1,413.11 nice profit for the buyer, Thanks for the greatly detailed video!
Really enjoying video from start to finish. Amazing that the steps of gold filled refining process is so different then your / the 10k & 14k refining process-video. I can imagine Alchemists where considered magicians back in the days.
@@roguekwads_fpv7368 The original poster is spending quite a bit on the chemicals he uses, to get a return of slightly more value in gold. Blame USA is being sarcastic, but his/her point is valid - is the cost & time involved worth the effort?
Good evening Mr. Sreetips. Long time watching, first time commenting. I have to say that I love that you you refined your Black and Decker into a Gold and Decker.
Anyone who wishes to learn how it's done will watch the entire video, maybe several times. Anyone who just wants to see the final product and don't care about learning the process will do just as you did. Thanks for watching.
I know we’ve talked about this before, but I’m going to point out once again that you look exactly like a retired senior chief lol. Thanks for your videos shipmate!
Hello sreetips, I have about 10 lb of marked gold filled jewelry and scrap. A vast majority of this jewelry and scrap is gold colored or looks like gold except on the edges where some of it is wearing off. A small percentage of the marked gold filled jewelry and scrap is either very bright like Steel with no color or it is copper colored. Has the gold worn off this jewelry and scrap? Or should I process it along with the gold colored jewelry and scrap?
Philip, the thick coating of gold does wear off over the years. It's usually around the edges. Then it becomes very apparent because you can see the base metal and the thick gold coating at the point of wear. For gf stuff wore through clean down to the copper, your yield will suffer. If it were me and I had ten pounds, I would process it in one pound batches starting with the good stuff first. Especially if working as a beginner. The stuff that's worn through, you'll have to make a judgement call.
That's a good idea thank you for the advice. After doing some research online I think some of the very bright white colored scrap and Jewelry is white gold filled. I will definitely process that all separately just to be sure.
I like this video especially that sreetips said ML every time is even better that way there is no assumptions that he actually used another unit of measurement...
Gold plated is base metal (brass) that is electroplated with copper, then a thin layer of gold electroplated over the copper. The gold is maybe 5 microns thick. A micron is a millionth of a meter. GOLD FILLED: a piece of brass with a sheet of 12 karat gold on the top and bottom of the brass is heated red hot and passed through rollers into a uniform thickness forming a thick layer of gold on top and bottom. It's then used to make jewelry. Thousands of time thicker than electroplate.
@@sreetips I have seen gold filled silver jewelry. I have a sheet that is 1/20 12K on one side and sterling silver on the other. I have no idea what the jeweler from whom I bought it intended to use it for.
@ 34:43 I was thinking the Corningwear bowl with the reaction vessel in it might break when you lifted it from the side. Man, I'm glad it didn't. Great video. Lots of stressful work there. Kudos!
Four nines can be done at the hobby level. But there is really no reason to do it. Three nines is the industry standard. I could get four nines by dissolving and precip twice using AR and SMB. Then dissolve the gold powder a third time with chlorine gas and precip with oxalic acid. But the only way to tell if four nines is achieved is to have an ICP assay performed. That would make a good video!
I watched the whole thing, thought it was a very good idea to include the process as related to cleaning the materials. To me it would cut back processing time and yield a better gold content
Reminded me of Chem 102.(what I remember from 50 years ago...). Watched the whole thing......and thoroughly enjoyed the whole thing! Excellent video, my friend!
Love your work and how cautious you are.....the end result is beautiful and worth all the wait and hard work.......even the small nuggets are worth the watch.......
I'm starting to get items (equipment) that I'll need to refine. I always try to get things for as cheep as possible, because of my fixed income. I've accumulated alot of the smaller more basic items for free going around town and... well, scrapping!! I've inspected each item for quality and I've had to get rid of a few things that isn't good enough for the job. People will get rid of some very expensive things out there!! Have a GREAT Day!!! P.S. Learning possibly more the 2nd time around!!! Thanks!!
@@TheMFrelly The dude is saying ML Not Mill. Try following along with the comment. The joke is he keeps saying ML,ML,ML,ML........................ Get it now?
I went to a good Catholic high school and a pretty good university. Out of all those years of schooling, I don't believe I had a science teacher that taught me nearly as much as you have with your videos.
I've put hot metal into glass containers hundreds of times and have never had a problem with cracking or exploding. Please see my video on refining karat scrap. In that video I pour molten metal into water in a metal container. Every now and then I'll get the molten metal too hot and it does explode when it hits the water. Scares the ghost out of me every time it happens, thankfully that's not very often.
Good Job, I did computer recycling for about 5 years and collected a lot of chips, gold fingers, boards, etc and still have it in a cargo container and would love to do this. I'm sure I'd have a fair amount of gold bars
I did the mental math and only expected a few grams of gold. Gold fill has more gold than gold plate but is generally worthless. You would have to accumulate much of it to make money from the scrap. I used to go to yard sales and buy scrap gold from the people there. It was a lot of fun and I made some money. It was easy if a divorce had just happened, they were happy to get rid of wedding rings. And wives would make the husbands get rid of jewelry gifted from old girlfriends. I always paid cash and I never cheated anyone. I gave my wife and daughters nice gold necklaces and bracelets that were too good for the scrap pile. There was some jewelry I regret selling for scrap but I needed the money. I had a very nice wedding/engagement ring set that was made in 1932. It came in the original box from a jewelry store in Washingtion DC. It had 4 diamonds to equal 1 carat and was made of platinum. I didn't scrap it but I did sell it as jewelry. for a good profit.
Very good, awesome process and well explained. It would be great to see the continuation in this video of how to precipitate the silver off the nitric acid that is disposed. Thanks a lot. Liked and subscribed!
I tinker around with small scrap, but not on this scale of furnaces, fume and heat mitigation and hi-tech processing. I cut up steel lids from jars and bottles and stuff these peices along with twist top lids into steel drink cans/tins [ whatever you wanna call them ], and I pull apart aluminium caps with those ring pulls and pull out, or scrape out as necessary, the inner HDPE linings and then stuff those into aluminium cans not fit for deposit redemption, then crush when filled, and I manually crunch those aluminium liquor bottle caps which I like to stuff into those aluminium bottles. Got it down pat for nifty little collections of scrap. No afterthoughts to do with processing peoples' keepsakes or mementos.
@@sreetips No, of course, may not have worked that stuff, you appear to go for the precious metals. I'm not in your league, skill-wise or any other-wise. I was thinking of the early preamble with the early sorting. You would do way better than I ever would if you did do any work in aluminium or steel.
I did some rough figuring , removed costs of chemicals , fluxes , filters, ect. , the enitial costs of buying the scrap jewelry . Figuring in the time for this whole process , you are barely making minimum wages ! WOW that's a lot of work !
For material like this, it is more a process documentary than an attempt to make a profit from the refining. The same is true for the videos he has done on refining computer scrap.
Great video! You must have had a few pieces of 1/5th GF mixed in to get such a good recovery. I love finding good deals on Gold Filled items, it's one of the many things I'm stockpiling for future recovery and refining.
I was taken aback at the scale. I couldn't believe it. And I even took some of the pieces out during the process. I think that the key is in the nitric boils. Keeping the foils in the hot nitric to get rid of as much base metal as possible. And the incineration before the refining is very important.
I have never seen 1/5th GF, it is likely to be quite rare. But it wouldn't take a lot of 1/10k12GF to get the recovered gold up to what you obtained. If your lot had been all 1/10k12GF, the theoretical recovery would be 37 grams.
*To make this more profitable if you install a simple scrubber to the top of the nitric acid beaker that bubbles the red NO2 into water you will recover 1 liter of mild-moderate strength nitric acid for every litre of conc you start with. That's just money going out the fume hood* Also is your fume hood outside all corroded and discolored from the gallons of NO2 that flow around it?
what a process... I've hung on till the end and it surprised me how much work it is. Thank you for the whole vid, i saw, i learned but i dont gonna do it.. way to toxic process

The hydrochloric acid provides a ready supply of chloride ions (Cl−), which react with the gold ions to produce tetrachloroaurate(III) anions, also in solution. The reaction with hydrochloric acid is an equilibrium reaction that favors formation of chloroaurate anions (AuCl4−). This results in a removal of gold ions from solution and allows further oxidation of gold to take place. The gold dissolves to become chloroauric acid. In addition, gold may be dissolved by the chlorine present in aqua regia. Appropriate equations are:
Au + 3 HNO
3 + 4 HCl {\displaystyle {\ce {>}}} {\displaystyle {\ce {>}}} [AuCl
4]−
+ 3 [NO

If the aqua regia solution only contains gold, solid tetrachloroauric acid may be prepared by boiling off excess aqua regia, and removing residual nitric acid by repeatedly heating with hydrochloric acid. That step reduces nitric acid (see decomposition of aqua regia). If elemental gold is desired, it may be selectively reduced with sulfur dioxide, hydrazine, oxalic acid, etc.[6] The equation for the reduction of gold by sulfur dioxide is:
2 AuCl−
4 (aq) + 3 SO
2(g) + 6 H

Why did you repeat everything 3 times?
I was going to say the same thing
I thought the nitric acid was a neutrilizer
Great video. I was especially impressed with the self critique, it is the best method of learning.
I actually watched the whole video, amazing
👍you are awesome. The chemistry that it takes to refine gold is outstanding. I didn’t know you could take gold turn it into a liquid and bring it back. Beautiful thing!
Fantastic process as always. So satisfying to watch. Especially that melt at the end wow. I'd love to see a high speed slow motion of the meta bisulfite precipitating out the gold (plus many more reactions). Destin from Smarter every day might be willing to record that if you send him an email. That would be cool.
ScreeTips is like the Louis Rossmann of board level repairs. Instead of hiding his tips, shares it with the world. :)
Ah perfect! I recently picked up a large collection of gold filled ladies watches and was planning on refining them! this will be a great refresher for me!
bullshit
That was a total pleasure to watch, definitely picked up a few tricks!
sreetips, love watching your videos. haven't been on the forum in ages... but still just enjoy how thoroughly and methodically you explain everything to the viewers! haven't added the lab to my new house yet so haven't refined anything in the last couple years... looking forward to starting it again!
Hello Edgar!
Absolutely amazing mr man. . I’m in total shock that this is a possibility
If I had know extracting gold was this easy and simple, I would have done this years ago, instead of wood working ;-) . Great video I am in awe...Ken
Never too late, Im about to start doing this soon lol
Your are an Absolute Master of your craft.
Wow I never realized what a big process it is to get back pure gold from scrap gold thank you for the education re Gold
It is easier if you are not starting with gold filled metal. It also requires far less nitric acid.
Very cool video. Sure beats working in an insurance claims office like I do.
#Ifeelbadforyoumanthatsprobablynotyoudreamjob
a nice bite of work 😋 to clean up that gold that was impressive thank you for sharing the process and the time it took. i see where patients is a valuable component of this and you got a good payment for your efforts. thank you for sharing your time and information on this 😊
That's a LOT of work over MANY days... for $900. Not sure it is worth it, especially when you add in the cost of the chemicals and glassware. But if you are happy doing it, then have fun!
That it's 1170 at spot. If you try to buy that from anyone you will pay an extra 100$ for it.
Good to see your face on a video sir! You are much younger than I expected! My Dad is a career chemist, mostly sulphur research.👍
You did well, eBay fee 9.9% and PayPal 3%, wouldn't a bullion dealer pay 90% spot?
I sell my gold to Elemetal Direct. They pay 98% of spot. This bar sold under that but I don't care. I'm trying to promote my social media presence. I've got some more gold coming up in future videos. Eventually the bars will start to bring a premium. But for now I have to pay my dues and let the chips fall where they may.
@@sreetips I'll subscribe, I enjoyed the content. I buy jewellery and scrap. I will have to start collecting more rolled gold
Bullshit...Pay your dues?
You own no dues.
@@madspacepoet4840 I think you do owe dues
Nope its more like 65% spot
I watched the whole video, looked at the 2018 selling and value price then calculated the today price $1,413.11 nice profit for the buyer,
Thanks for the greatly detailed video!
Recalculate for when gold hits $5000 - it's a mathematical certainty.
Just imagine a police officer walking in thinking that your running a meth lab or something.
Really enjoying video from start to finish. Amazing that the steps of gold filled refining process is so different then your / the 10k & 14k refining process-video. I can imagine Alchemists where considered magicians back in the days.
Alchemists were trying to create gold, not extract it.
Scientist cant explain the lack of birds in the local vicinity !! go figure!
he has an air scrubber... that's the proper way to create a fume hood
I like your internetcommentetiquette!
Who cares about birds
Birds are not made of Gold.
i was concerned about the fumes actually. so i guess an air scrubber eliminates toxins from the air?
You really went do the items and gave a detailed description of what they are first when you start it and second when you broken them down.
$15.6 million in chemicals, total value $990
lmfao
Any idea of the real value of all the chemicals and other wasted materials used in this process? I kept thinking it wouldn't be worth it.
I don't understand this comment or the replies can someone explain please
@@roguekwads_fpv7368 The original poster is spending quite a bit on the chemicals he uses, to get a return of slightly more value in gold. Blame USA is being sarcastic, but his/her point is valid - is the cost & time involved worth the effort?

Good evening Mr. Sreetips. Long time watching, first time commenting. I have to say that I love that you you refined your Black and Decker into a Gold and Decker.
The frankenoven!
did anyone actully watch the whole video or the first 15 minutes then skip to the end?
Anyone who wishes to learn how it's done will watch the entire video, maybe several times. Anyone who just wants to see the final product and don't care about learning the process will do just as you did. Thanks for watching.
@@sreetips good answer 😀
i watched the entire process. start to finnish no skipping nothing didnt move the entire time.
@@coreyscheidt Me too. Every minute non-stop.
Absolutely! I watched the whole process. I even had flashbacks to college chemistry! :o)
I know we’ve talked about this before, but I’m going to point out once again that you look exactly like a retired senior chief lol. Thanks for your videos shipmate!
At 14:39, why only 2G per 100G? I thought GF of 12% gold was about 5% gold, am I wrong or is the recovery so bad?
12k is 50% gold. 1/20 is .05 or 5% so 5% of 50% is 2.5% or 2.5 grams of pure gold per 100 grams of 1/20 12k GF. It's just math.
@@sreetips THANK YOU!!!
@@sreetips s
Interesting; much more work than I would have thought, thank you for sharing.
Hello sreetips, I have about 10 lb of marked gold filled jewelry and scrap. A vast majority of this jewelry and scrap is gold colored or looks like gold except on the edges where some of it is wearing off. A small percentage of the marked gold filled jewelry and scrap is either very bright like Steel with no color or it is copper colored. Has the gold worn off this jewelry and scrap? Or should I process it along with the gold colored jewelry and scrap?
Philip, the thick coating of gold does wear off over the years. It's usually around the edges. Then it becomes very apparent because you can see the base metal and the thick gold coating at the point of wear. For gf stuff wore through clean down to the copper, your yield will suffer. If it were me and I had ten pounds, I would process it in one pound batches starting with the good stuff first. Especially if working as a beginner. The stuff that's worn through, you'll have to make a judgement call.
That's a good idea thank you for the advice. After doing some research online I think some of the very bright white colored scrap and Jewelry is white gold filled. I will definitely process that all separately just to be sure.
I could do that. But metal refining is a hobby of mine. I would prefer to practice my own skills.

So you can go through it?
This is one of the most fascinating videos I have seen. Absolutely amazing.
"should be avoided like the plaque"
Well, plaque should be avoided, but I think he meant the plague.
Hello from Norway 😊
Very interesting to see clip from "olds" Days.
Muth job to take apart the gold, but it locks so fin.
Take care sir😊
"about 200 ml water and 100 ml nitric acid"
*Quick small spray of water*
*Loooong giant pour of acid*
I like this video especially that sreetips said ML every time is even better that way there is no assumptions that he actually used another unit of measurement...
What is the difference between gold plated and gold filled?
Gold plated is base metal (brass) that is electroplated with copper, then a thin layer of gold electroplated over the copper. The gold is maybe 5 microns thick. A micron is a millionth of a meter. GOLD FILLED: a piece of brass with a sheet of 12 karat gold on the top and bottom of the brass is heated red hot and passed through rollers into a uniform thickness forming a thick layer of gold on top and bottom. It's then used to make jewelry. Thousands of time thicker than electroplate.
@@sreetips I don't think I've ever seen that. Interesting 🙂
The usual karat gold used for gold filling is 12K, but I have seen a little 14K. I seem to recall that you even mentioned one such piece in the video.
th-cam.com/video/A2ZmugOJ4qo/w-d-xo.html
@@sreetips I have seen gold filled silver jewelry. I have a sheet that is 1/20 12K on one side and sterling silver on the other. I have no idea what the jeweler from whom I bought it intended to use it for.
@ 34:43 I was thinking the Corningwear bowl with the reaction vessel in it might break when you lifted it from the side. Man, I'm glad it didn't. Great video. Lots of stressful work there. Kudos!
That’s a hell of a lit of patient fiddling but what a reward! Surely with that many stages of purification it must be four 9’s?
Unlikely. It takes a very good refiner to get three 9 gold through simple acid digestions/precipitations.
I would say yes, at least four 9's. It is not the acid process that most fail at in reaching four 9's it is usually poor filtering.
I've refined hundreds of ounces of pure gold. The assay comes back three nines fine - every time.
How can 4 9 purity be reached than?
Four nines can be done at the hobby level. But there is really no reason to do it. Three nines is the industry standard. I could get four nines by dissolving and precip twice using AR and SMB. Then dissolve the gold powder a third time with chlorine gas and precip with oxalic acid. But the only way to tell if four nines is achieved is to have an ICP assay performed. That would make a good video!
I watched the whole thing, thought it was a very good idea to include the process as related to cleaning the materials. To me it would cut back processing time and yield a better gold content
I think he could have said ml a few more times lol
You are breaking all the rules of chemistry!
It's a good thing you're not a mad scientist, you would be dangerous. lmao
That's the kind of video I really like, nice and long!!
Great Job Sreetips!!!
you drink everytime he said acid
nahhh everytime he said emmm ellll
Or every time he says gold filled lol
Reminded me of Chem 102.(what I remember from 50 years ago...). Watched the whole thing......and thoroughly enjoyed the whole thing!
Excellent video, my friend!
If you want to save boring yourself hearing this person say the same thing 1000 times over, skip to 15:20
You,,,,cock.
Love your work and how cautious you are.....the end result is beautiful and worth all the wait and hard work.......even the small nuggets are worth the watch.......
Too much work, time, material, chemicals, etc for such little gold. But interesting!
I'm starting to get items (equipment) that I'll need to refine. I always try to get things for as cheep as possible, because of my fixed income. I've accumulated alot of the smaller more basic items for free going around town and... well, scrapping!! I've inspected each item for quality and I've had to get rid of a few things that isn't good enough for the job. People will get rid of some very expensive things out there!!
Have a GREAT Day!!!
P.S. Learning possibly more the 2nd time around!!! Thanks!!

The way you put the hot metal straight into the beaker like that tells me that one day its going to crack or explode :)
I've put hot metal into glass containers hundreds of times and have never had a problem with cracking or exploding. Please see my video on refining karat scrap. In that video I pour molten metal into water in a metal container. Every now and then I'll get the molten metal too hot and it does explode when it hits the water. Scares the ghost out of me every time it happens, thankfully that's not very often.
Thanks for showing us how to roll your thumbs in the beginning
Nervous habit.
Good Job, I did computer recycling for about 5 years and collected a lot of chips, gold fingers, boards, etc and still have it in a cargo container and would love to do this. I'm sure I'd have a fair amount of gold bars
I did the mental math and only expected a few grams of gold. Gold fill has more gold than gold plate but is generally worthless. You would have to accumulate much of it to make money from the scrap.
I used to go to yard sales and buy scrap gold from the people there. It was a lot of fun and I made some money. It was easy if a divorce had just happened, they were happy to get rid of wedding rings. And wives would make the husbands get rid of jewelry gifted from old girlfriends. I always paid cash and I never cheated anyone. I gave my wife and daughters nice gold necklaces and bracelets that were too good for the scrap pile. There was some jewelry I regret selling for scrap but I needed the money. I had a very nice wedding/engagement ring set that was made in 1932. It came in the original box from a jewelry store in Washingtion DC. It had 4 diamonds to equal 1 carat and was made of platinum. I didn't scrap it but I did sell it as jewelry. for a good profit.
I’m doing nearly the same thing. Except instead of reselling for a profit, I use it to make videos.
Damn good 👍👌👏. The fact you use your profits for more educational vids is awesome! Thanks man!
magic! excellent and thank you for sharing your valuable expertise, skills and knowledge
Another incredible video! And another beautiful bar! Thank you!
I love watching your old vids . That ive already watched few times 😅
I view some multiple times. Makes 40 minutes go by like 15.
Love you BigBrother you are so bad to the bone it hurts to think about how much I need to learn
Very good, awesome process and well explained. It would be great to see the continuation in this video of how to precipitate the silver off the nitric acid that is disposed. Thanks a lot. Liked and subscribed!
I watched it all... And realized this is why I don't want to deal with Gold recovery, lol! I'll send it out if I ever get that much!
Getting pure gold from any source is never easy.
It is worth $1,179.04 today, I wish that I would have known about this channel back when you sold it. I just found your channel this morning.
Not to worry. I'll be making some more videos and selling the metal from those videos on my eBay store. I ship to USA locations only.
I tinker around with small scrap, but not on this scale of furnaces, fume and heat mitigation and hi-tech processing. I cut up steel lids from jars and bottles and stuff these peices along with twist top lids into steel drink cans/tins [ whatever you wanna call them ], and I pull apart aluminium caps with those ring pulls and pull out, or scrape out as necessary, the inner HDPE linings and then stuff those into aluminium cans not fit for deposit redemption, then crush when filled, and I manually crunch those aluminium liquor bottle caps which I like to stuff into those aluminium bottles. Got it down pat for nifty little collections of scrap. No afterthoughts to do with processing peoples' keepsakes or mementos.
I've never worked with steel to aluminum. Aluminum can be troublesome in some of the refining processes so I remove if I find any.
@@sreetips No, of course, may not have worked that stuff, you appear to go for the precious metals. I'm not in your league, skill-wise or any other-wise. I was thinking of the early preamble with the early sorting. You would do way better than I ever would if you did do any work in aluminium or steel.
I notice that the color of the different solutions is most vivid when there is only one metal dissolved.
I did some rough figuring , removed costs of chemicals , fluxes , filters, ect. , the enitial costs of buying the scrap jewelry . Figuring in the time for this whole process , you are barely making minimum wages ! WOW that's a lot of work !
For material like this, it is more a process documentary than an attempt to make a profit from the refining. The same is true for the videos he has done on refining computer scrap.
Great video! You must have had a few pieces of 1/5th GF mixed in to get such a good recovery. I love finding good deals on Gold Filled items, it's one of the many things I'm stockpiling for future recovery and refining.
I was taken aback at the scale. I couldn't believe it. And I even took some of the pieces out during the process. I think that the key is in the nitric boils. Keeping the foils in the hot nitric to get rid of as much base metal as possible. And the incineration before the refining is very important.
I have never seen 1/5th GF, it is likely to be quite rare. But it wouldn't take a lot of 1/10k12GF to get the recovered gold up to what you obtained. If your lot had been all 1/10k12GF, the theoretical recovery would be 37 grams.
@@buggsy5 I have some 1/5th 14k GF, it is hard to come by, but has a lot more gold that 1/10 or 1/20.
Yes, twice as much as the 1/10K14 and four times as much as the 1/20K14.
The best refining video I've ever seen! Thanks! :)
*To make this more profitable if you install a simple scrubber to the top of the nitric acid beaker that bubbles the red NO2 into water you will recover 1 liter of mild-moderate strength nitric acid for every litre of conc you start with. That's just money going out the fume hood* Also is your fume hood outside all corroded and discolored from the gallons of NO2 that flow around it?
I've had eruptions of beakers full of acid shoot all over the inside of the hood. Some of it got on the metal and corroded it.
Yes, that was brilliant!! 🙂🙂👍
(Now can you make a video showing you refining the silver solution?? 🙂👍)
Lovely job have never seen such detail in the videos I've watched.
I love it when you talk that dirty alchemical talk about incinerating to redness.
Thank you for the video.
Great video! Thanks for mentioning solution temperature in Celsius!
what a process... I've hung on till the end and it surprised me how much work it is. Thank you for the whole vid, i saw, i learned but i dont gonna do it.. way to toxic process
You bet. Refining gold at home is not for everyone.
