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
Perhaps the most thorough video on method and procedure. You obviously are as methodical to your collection process as this is not your primary source of income but rather a side aspect of an old school jeweler. Good demonstration of 'MacGuyver' skills with basic understanding of chemistry and physics with a little smathering of the economic side of the equation. Kudos...and well done.
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'm in the process of precipitating some gold and some gold scrap, I'm watching your videos step by step as I take on the science of refining gold.

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.

Thank you sreetips for some very informative video's showing the method & techniques involved from the UK. I am up-scaling what ive been doing for a hobby for a few years now as ime getting so much computer & jewellery scrap here its now worth the learning.
I watched the video from beginning until the end and I must say that this is the first time that I really learned something about the whole proces of refining gold. You see on TV Gold Rush and hear these amounts of gold they find and now i realise that refining that gold will cost a lot of ounces of gold. In Parker Schnabels case maybe hundreds or thousands of ounces of gold but you never hear about that. You only hear the gross earnings never the netto earnings. Thanks for the video sreetips.

Destin from Smarter every day might be willing to record that if you send him an email. That would be cool.
Thank you so much for slowing and expanding the formerly complex chemical processes so that a Layman like me can understand it I loved the video thank you
I make these videos, with as much detail as possible, for the benefit of those who want to learn. I only wish that videos like mine were around when I first started refining nine years ago.
Are they all filled with gold? seems silly to fill something with gold, surely you'd want the gold on the outside, and fill it with something cheaper? In UK we do just that. and call it gold-plated. I realise that in this case, "filled" probably does mean an outer covering. I just can't resist pointing out the absurdity of using the term "filled".
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.
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.

How does Sreetips come up with his profile names? Just curious where Bafelous, Kadriver, and Sreetips came from? Is there a hidden meaning or anything like that?
No. Bafelous is a meaningless word. Kadriver is an old user name on the goldrefiningforum.com it means; King Air Driver because I used to fly one (King Air). And sreetips is another meaningless word, like Kodak.
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, 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!
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.
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!
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 😊
👍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!
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 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!
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!
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.
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!
@@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?
@ 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!
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.
Ive never tried sodium nitrate. You can buy nitric at any chemical supply. They just don’t ship to a residential address. Get your friend who owns a business to receive it for you.
I add sulfuric every time I dissolve, just as a precaution. It hurts nothing, costs almost nothing and provides a benefit just in case any lead made it through.
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.......
@@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 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...
I do have a question about your leftover bucket 1 and 2 I would like to see how you bring back out the silver before I make a silver refine / to a bar. I have watched both silver and gold Thanks so much
I thought gold fill was too thin to recover? You made a thermal over, that's awesome.... Do you make your money back after spending so much on acids and such. Can't find your ebay, may put a link to it in the description?
@@sreetips I plan on doing as I saw you do it. Borax and torch. The gold precipitate, is it true if you soak it in ammonia it removes all but the gold?
@@sreetips Ok I was told about it and read only 1 thing about it. Company called ishor that sells gold process kits. Ok wish me luck tomorrow on the melts. If all goes well its because of you, taking the time and putting up with me. Thanks
@@sreetips Well it didnt turn out like I had hoped. Total had close to 86 grams of various metals. The brown SMB drop was dry 9 grams and maybe got 1 gram after melt. I got total maybe all the metals 6-7 grams. The hand held tanks of mapp gas will that melt the brown precipitates of gold?
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.
Thank you so much! I was wondering what R.P.G. ment. I was wondering, I want to do a batch of pins. I'm using sulfuric acid, water and diluted table salt. Have you dissolved base metal in this way before? If so I can go check out the video! And thank you so much for all you do!
Yes, I did trimmed circuit card fingers. I was under the direction of some chemists on sciencemadness.org - it worked, but it was inefficient and cumbersome. I’ve never used it since.
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!
*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?
Sreetips, it looks to me like the process itself would benefit from breaking down the scrap further, into something the consistency of 'french press' coffee grounds.. in your experience do you find that grinding or powdering the base materials speeds the action of the nitric later in the process? @47:20 - Thanks for these amazing videos. You're doing excellent work.
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.
Could you have set up your drip hose for incremental nitric dosing at the beginning when you were dissolving the base metals? Just wondering why you didn't go that route.
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!!
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.
You did one of these videos a while back, in that video you pulled out all the magnetic material. You said that magnetic gold filled had to be processed differently. Do you plan on making a video on how to process magnetic gold filled? I've been watching your videos over and over for the past 3 years prepping myself to refine some gold. Thank you for sharing with us.
Brenda, I excluded magnetic in the last video. In this video, however, there were some magnetic wrist watch cases. I included them with no problems. In this video I carefully picked EVERYTHING apart and removed any iron and steel pieces before going to nitric treatments because nitric does not dissolve iron very well. If you want to try some GF scrap its best to remove any iron or steel and you'll get a better result. This was a very difficult video to make. But I included as much detail as I could so that you could see the little problems that can throw the whole batch into a nightmare. And there are other problems that can happen that were not shown because I didn't encounter them. If one little piece of soft solder gets in there it can make a mess of the whole thing. Processing GF scrap is not for beginners, but you got to start somewhere.
You mentioned the lead causing problems but you weren't very specific. I wonder if you could explain exactly what kind of problems the lead would cause?
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 make these videos, with as much detail as possible, for the benefit of those who want to learn. I only wish that videos like mine were around when I first started refining nine years ago.
Thank you for showing this exacting process. I see now that this is hardly a DIY affair.
Sree tips shop is a gold filled mine, watching this video got me out my gold filled mind, in this video he says gold filled 99 times.
Are they all filled with gold? seems silly to fill something with gold, surely you'd want the gold on the outside, and fill it with something cheaper? In UK we do just that. and call it gold-plated. I realise that in this case, "filled" probably does mean an outer covering. I just can't resist pointing out the absurdity of using the term "filled".
If i had a dollar for every times he says ML and nitric acid - I could afford some gold :) great video, very informative
paul - you could afford platinum if you had a nickel for every time he says “baaatch.”
If I had a dollar for every time a cry at night I would have many dollars
Don't know wy he says ML, MOST people say Mil. ML is short for Milliliters of course.
No every time he said gold or stainless steel or steel
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.👍
I watched it a 1.25% speed. Thanks for the upload. great job.
I watched at 2x speed with captions. Turns 90 minutes into 45
Great video. I was especially impressed with the self critique, it is the best method of learning.
Absolutely amazing mr man. . I’m in total shock that this is a possibility
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.

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]+

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−

How does Sreetips come up with his profile names? Just curious where Bafelous, Kadriver, and Sreetips came from? Is there a hidden meaning or anything like that?
No. Bafelous is a meaningless word. Kadriver is an old user name on the goldrefiningforum.com it means; King Air Driver because I used to fly one (King Air). And sreetips is another meaningless word, like Kodak.
@@sreetips ah. Gotcha. Thank you! 👍
@@sreetips oh wait, I get it. Bafelous is meant to BAFFLE US. Lol…
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, 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!
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)
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!
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
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 was a total pleasure to watch, definitely picked up a few tricks!
👍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!
Your are an Absolute Master of your craft.
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😊
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?
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!
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?
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!

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.
This is one of the most fascinating videos I have seen. Absolutely amazing.
Just imagine a police officer walking in thinking that your running a meth lab or something.
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,

Recalculate for when gold hits $5000 - it's a mathematical certainty.
Very cool video. Sure beats working in an insurance claims office like I do.

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?

@ 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!
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.
"should be avoided like the plaque"
Well, plaque should be avoided, but I think he meant the plague.
Where do you source your nitric acid? Is nitric acid substitute (sodium nitrate) worth bothering with? Thank you in advance.
Ive never tried sodium nitrate. You can buy nitric at any chemical supply. They just don’t ship to a residential address. Get your friend who owns a business to receive it for you.
I think he could have said ml a few more times lol
Interesting; much more work than I would have thought, thank you for sharing.
you drink everytime he said acid
nahhh everytime he said emmm ellll
Or every time he says gold filled lol
Was there a double precipitation of lead on this refining? There was some sort of redundant step there?
I add sulfuric every time I dissolve, just as a precaution. It hurts nothing, costs almost nothing and provides a benefit just in case any lead made it through.
If you want to save boring yourself hearing this person say the same thing 1000 times over, skip to 15:20

I do have a question about your leftover bucket 1 and 2 I would like to see how you bring back out the silver before I make a silver refine / to a bar. I have watched both silver and gold Thanks so much
I thought gold fill was too thin to recover? You made a thermal over, that's awesome.... Do you make your money back after spending so much on acids and such. Can't find your ebay, may put a link to it in the description?
The total cost all in is about $100 usd.
You have one of the coolest channels on TH-cam.
Thank you
How much you charge to recover gold from gold filled scraps? junksilverbuyer@gmail.com
Dry weight of precipitate if done correct. Is it the same as melted button weight? Thanks to you and your stock pot video's I am getting.
Should be very close. Some loss does happen during the melt depending on your technique.
@@sreetips I plan on doing as I saw you do it. Borax and torch. The gold precipitate, is it true if you soak it in ammonia it removes all but the gold?
I've never tried it so I don't know if it's true.
@@sreetips Ok I was told about it and read only 1 thing about it. Company called ishor that sells gold process kits. Ok wish me luck tomorrow on the melts. If all goes well its because of you, taking the time and putting up with me. Thanks
@@sreetips Well it didnt turn out like I had hoped. Total had close to 86 grams of various metals. The brown SMB drop was dry 9 grams and maybe got 1 gram after melt. I got total maybe all the metals 6-7 grams. The hand held tanks of mapp gas will that melt the brown precipitates of gold?
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.
Thank you so much! I was wondering what R.P.G. ment.
I was wondering, I want to do a batch of pins. I'm using sulfuric acid, water and diluted table salt. Have you dissolved base metal in this way before? If so I can go check out the video! And thank you so much for all you do!
Yes, I did trimmed circuit card fingers. I was under the direction of some chemists on sciencemadness.org - it worked, but it was inefficient and cumbersome. I’ve never used it since.
Ok. Got it . Im going to process a bunch of gf scrap next week . How do we precipitate the silver from the remaining solution ???
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!
Damn good 👍👌👏. The fact you use your profits for more educational vids is awesome! Thanks man!
*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.
Sreetips, it looks to me like the process itself would benefit from breaking down the scrap further, into something the consistency of 'french press' coffee grounds.. in your experience do you find that grinding or powdering the base materials speeds the action of the nitric later in the process? @47:20 - Thanks for these amazing videos. You're doing excellent work.
Bring into a powder would take much time and effort. I'd rather let the acids do the work for me.
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.
Wow! No simple process. Never realized this before. You certainly worked hard for that $1,100.00. Nice job.
Could you have set up your drip hose for incremental nitric dosing at the beginning when you were dissolving the base metals? Just wondering why you didn't go that route.
Didn’t think of it
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.
how much waste solutions comes of that amount of gold and what happens to the waste when you are done with it mr sreetips ??
Waste treatment
@@sreetips and with that are they able to recycle it for other uses at all im sorry for asking ive watched all your vids and i love what you do
You did one of these videos a while back, in that video you pulled out all the magnetic material. You said that magnetic gold filled had to be processed differently. Do you plan on making a video on how to process magnetic gold filled? I've been watching your videos over and over for the past 3 years prepping myself to refine some gold. Thank you for sharing with us.
Brenda, I excluded magnetic in the last video. In this video, however, there were some magnetic wrist watch cases. I included them with no problems. In this video I carefully picked EVERYTHING apart and removed any iron and steel pieces before going to nitric treatments because nitric does not dissolve iron very well. If you want to try some GF scrap its best to remove any iron or steel and you'll get a better result. This was a very difficult video to make. But I included as much detail as I could so that you could see the little problems that can throw the whole batch into a nightmare. And there are other problems that can happen that were not shown because I didn't encounter them. If one little piece of soft solder gets in there it can make a mess of the whole thing. Processing GF scrap is not for beginners, but you got to start somewhere.
Yes, that was brilliant!! 🙂🙂👍
(Now can you make a video showing you refining the silver solution?? 🙂👍)
You mentioned the lead causing problems but you weren't very specific. I wonder if you could explain exactly what kind of problems the lead would cause?
Lead, in just trace amounts, ruins the malleability and ductility of gold. That’s why I always add a little sulfuric to precipitate it out - 100%
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.
Can you make a video about everything you need to do this? Tools/chemcials and glassware?
You just watched it. It’s all there. I’ve left nothing out.
@@sreetips awesome
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
