Sreetips, I started stacking up my metal ducting in my shop for my exhaust hood vent setup. I'm pretty excited. I also put my prospecting tools in a Rubbermaid tote today. Organizing. Those nitric acid boils produce some nice colors. I can't wait to learn more about silver and gold.
30:40 Another reason to use silver to inquart instead of copper is because it takes twice as much nitric acid to dissolve copper than it does to dissolve silver. Since nitric acid is expensive, Silver is the better way to go.
I always enjoy these series of videos. Very few videos get 100% of my attention, yours are exceptional. Your content is honest, as you never leave out your mistakes.
I absolutely love watching an learning about ever you do. I haven't been on here for a while due to a apt. Fire an homelessness. But not hopelessness. Thanks for doing what you do. I love it!
Thankyou for your service Chief. My grandfather just passed last month. He was a Senior Cheif BT on the Allen M Sumner DD-692. He was also a CB retired in 1976.
Finally enough karat gold to refine and make alot of profit. Unlike normally, when you use more chemicals that cost more than the actual amount of gold you get in the end. But I'm so freaking pumped that this is almost an hour long. I love watching the long videos. It seems like the time goes by so fast on your videos. Love the content man. Can't wait for more!
By the way my 12 year old son watches with me sometimes. I'm trying to get him into science and chemistry more. We also watch Nilered/Nileblue and Cody's Lab. I'm trying to teach him young about the value of gold.
Hey old friend. Another perfect how to from you. The final video for your king pour is up next. Hopefully it wont be any more than a couple days now. Too bad the graphite crucibles don't last as long as the ceramics eh. I get the same small losses when heating silver. Some to atmosphere and little tiny round bits from the pour itself. They do add up. Fortunately the loss to atmosphere is lessened a lot as it collects on the underside of the lid on my furnace in little beads that will get large enough to either fall of or I pick them off with my bench pliers..
Maybe if you poured over a black sheet or piece of wood or something it'd be easier to see any silver which splatters out? Not sure how useful it'd be, but it might further minimize losses!
@@none.892 Thanks a bunch my friend. What I do see when making shot or grain is I see very small beads will bounce off the Ice. I use a 5 gal bucket with 16 litres od water and A bunch of Ice. When using snow I noticed no bouncers so I go to a friends that makes me crushed ice from his fridge and use that instead of ice cubes ir blocks. There is always the issue of the melting silver going to atmosphere. The only way to deal with that is to purchase ready made shot from a mint like RCM(Canada) but it is difficult to find.
Im loving your channel! Thanks for answering my question about why you use silver inquarting. The way you teach this art is fascinating to me. Thanks sreetips for the lessons!
What you were saying about using silver instead of copper to inquart the gold is a good reason to use silver, but not the only reason it’s a good practice. Another good reason is that it’s uses less nitric acid. The stoichiometry is that for silver it takes around 1.2 ml’s of 70% nitric acid to bring one gram into solution, whereas with copper it takes around 4.3 ml’s of 70% nitric to bring one gram into solution. So it takes less than 1/3rd the amount of expensive nitric to get the silver off the gold.
hey buddy do you have a microscope? i think it would be interesting to see a before and after of the inquarted gold shot, see if it gets visibly porous from the nitric boils.
This is actually an awesome idea. Even just pulling out one big flake of the gold and getting a microscope or just a macro lens view of it would be really cool.
If you notice at 15:30 there is that lovely green colour on the metal which shows copper still alloyed to the gold. I love it !!!! this is Chemistry !!!
Thanks for your therapeutic and educational work. And your service. I believe your ship and the USS Dixon were part of same task force DS 1. Her ship was a submarine tender. Always faithful.
I was on a Frigate in Norfolk when he was group 8. He would show up out of the blue so everyone had to be ready. I later worked for him at Buyers and our patches crossed when he was CNO. He visited my last ship and addressed the crew on the way to the podium he saw me and stopped to talk. Not bad for a Senior Chief Machinist Mate.
I had many COs while in the Navy. They were all very top-notch professional people. But Boorda was exceptional. The gunners called him Boom-Boom because he loved shooting the 5 inch 54. Plus, he was a brilliant tactician. He did things in an unconventional manner, and threw people off with his tactics because they weren’t expecting it. I consider it a privilege to have served with him.
That gold came out perfect, proves what you said in the video, Patience is the key, it's a very rare commodity and we're all so lucky you have plenty - can't wait for Pt4 :-) No Rush though :-)
Great to see that nitric on a drip. This series just keeps getting more educational. I am wondering if you might be getting some gold in the nitric. Granules of alloy will need the silver dissolved out in order to be able to reach the silver deeper in each granule. Depending on how well the alloy is mixed in the smelt, you may not be able to do this without sacrificing some gold in the process. Maybe a gold test on your solution would be useful to find out if that occurs?
Gold doesn't react with nitric acid, and pure gold doesn't really dissolve. For the gold to dissolve in the nitric acid it would have to react with it, but since that is not happening (apart from maybe once ever 10^20 Gold atoms) this is of no concern.
Very excited to see this series progressing so quickly. You're spoiling us on so much great content released so close together! I have a question or two about efficiency in the use of your acids and rinses. Is there generally less waste if you process your metals in smaller batches, or do larger batches produce less waste, proportionally? Also, could rinsing the silver off the gold be done more economically (as far as nitric and distilled water use) if you were to pour the gold into a filter in a funnel and rinse it with your squirt bottle between each nitric boil? Thanks in advance for your answers, if you choose to give me some. As always, I'm a huge fan of your work!
If you're doing chemistry I'd say that wasting water is not often a concern. You use as much as you need to, of course you can use a little less water in between nitric acid washs, or even leave out washing with water in between, but you can't use less nitric acid. If you use too little nitric acid you don't get rid of all the silver / copper / base metals and that gets you impure gold. What you could do to make it more efficient is perhaps stiring it with a magnetic stir bar.
What's more fun than watching sreetips refine a 25 OZT bar of gold? Watching him do it again! I'm on my second trip through this amazing journey, and man that brown gold looks great! I just purchased a copy of "Refining Precious Metal Wastes" by C.M. Hoke, and I am anxiously awaiting its arrival. It's not an inexpensive book, I paid $70 for it after tax, but it's going to be a very wise investment into my own knowledge. Whether or not I ever put it into practice is moot to me. I consider this type of knowledge to be valuable for its own sake. I do however, plan on setting up a lab of my own, and processing karat scrap and GF, GP jewelry. You are setting the bar really high with this huge batch of karat scrap refining. I'll be starting off with significantly smaller batches!!!
20:00 I like to make ice blocks for my cooler for work out of the Sterilite 6 Qt Storage Box's that sell for roughly $1 from Walmart each. they take about 10 hours to completely freeze. i also thought that you should have a spray nozzle to spray down you board when making shot. also you should have a taller bucket or can to hold more water higher then the turkey deep fryer pot. i suggest a Plastic Drum with Lid - 30 Gallon, Open Top, Blue which you can get for about $25 bucks from craigslist.
I'm sorry Mr. Streetips for getting so excited but this is what our young folk need to learn. Copper is one of the most exciting elements in my opinion and I love the oxidation states it produces, the colours are fantastic.
12:00 Have you thought about installing a 1/4"20 threaded insert into the side of your lab hood so you can mount the camera from inside the hood to: 1. Be able to pour the liquid away from you and 2. Have different angles of what is going on. The inserts are available at Home Depot or Lowe's for pretty cheap.
Well Sreetips i have been truly entertained to the point i was thinking of trying my hand at making my own gold bars. Your video is very informative even you show ur human sides of making mistakes. will continue to watch your future videos.
Man you are killing me with these mini series lol. Favorite bed time channel to watch. Great info man. If one were interested into getting involved what’s the best way to acquire the volumes of gold and silver to use for these?
ممنون بابت تمام زحمات شما ی سوال داشتم اینکه نحوه حرارت دادن به پودر طلا برای ذوب با هوابرش باید با هوای زیاد باشد یا کم و اینکه علت سیاه شدن طلا پس از ذوب چیست؟؟؟
To detect any traces of copper, just add some ammonia water into eluted acid-water sample (29:21). It does a very intensive indigo color from [Cu(H 2O)2(NH3)4]2+ en.wikipedia.org/wiki/Schweizer%27s_reagent
Beautiful caramel colored gold granules , sreetips, and a. testament to your exacting constant calculations. I'm spellbound by these processes, and I never get weary of seeing them. You've got me seriously considering doing some of these experiments myself, it looks like a fairly expensive layout for glassware, vacuum pump, heating/stirring plates, and fume evacuation booth, but the expense will be recouped rather quickly once I get things rolling. You make this look easy, but I know that it's not. You can blow the whole thing if you foul up at any step of the way. Thank you for sharing your successes and your failures with us, the astute viewer will take notes, and if they attempt to recover and further refine gold and silver themselves, watch out for the troubles that you experienced. Thank you again, for sharing your knowledge and expertise with us, I appreciate it very much!...... WH
But the blue tint is from Cu(NO3)2: the AgNO3 produces a clear solution. So rinsing until clear does not necessarily provide a silver-free solution. Do the Aqua Regia and the small quantity of silver should precipitate out as AgCl and can be collected via filtration when filtering the Aurochloric acid solution.Cheers
I don't know anything about chemistry, only what I watch on TH-cam. I watch a few others that put an excess of silver in, so that they do not need to do as many hot nitric acid boils. From what I understand that is because with so many silver atoms surrounding the gold atoms you can get to all of them with far fewer boils. Also, they are not getting to three-nines-fine either, and they don't care too much about the silver afterwards. Your electrolytic cell is unique, and probably contributes significantly to the overall process. Always fun to watch!

was going to ask a dumb question, but you covered it at 53:00 ,my question was you got a good surface area by melting the gold into granular , then used nitric acid to remove the base metals and silver, why go further with aqua regia HCl + HNO3, why not just melt it into the gold bar? so my guess is if you melted now you might have around a 23k gold bar.
The gold could have been melted but the problem is lead. If lead is present, even in trace amounts, it ruins the malleability and ductility of the gold. Refining with aqua regia is the only way to get the lead out completely
Im glad you answered the quesiton about why you use silver instead of copper in the video. Its a question I'd been pondering but hadnt yet asked. It might have been hard to find in the comment section. Copper is a lot easier for me to find than gold, since I deal with computer scrap. Im still a year away from any refining though. Its been 30 years since I was in a chemistry lab at university, but I reckon I can manage it now that my son is finishing up a chem degree :)
Piece of sanitary 316L ss, schedule 10, 12" pipe- 36" to 48" long to cool your pellets. Your beads just need a little more travel time through the water to keep from re-fusing on the bottom.
Testing for Silver in solution with HCL is very clever but remember that HCL concentrated will also dissolve some Silver chloride . redissolving your gold in aqua regia will defiantly give you 99.9 purity good work . You do know there are much faster and easier ways to do this . I do compliment you an your patients
Greetings! Nice videos. I've watched several so far. I spent 5 years total on USS MacDonough and USS Wm V. Pratt, which were the same class as the Farragut, back when they were still designated DLG's. :-)
Why do you add the excess nitric to silver just to consume the nitric acid? At around 24:30 in the video. If all you want to do is consume the nitric, couldn't you do something less expensive? I think I'm missing something here.
Silly question: Are the glass plates that you put on top of the beakers there solely to prevent foreign material from falling inside or is there an additional purpose?
Greetings to my dear teacher The metals palladium, platinum and rhodium are soluble in aqua regia solution. Now what happens if I use iron to deposit them? In my country zinc is very expensive . waiting for your answer !!!
Any acid in solution would oxidize the Iron forming ferrous ions, which would end up rendering ferric ions. The latter hydrolizes unless the pH is below 3. The product is insoluble ferric hydroxide Fe(OH)3. On heating it gives Fe2O3, contaminating the gold cement. You don't want this. I don't know the cons if vou decide to use a strongly acidified solution.
If you stirred slowly with a glass stir stick you could dissolve more in each batch due to the contact points of each piece of gold touching each other leaves some surfaces not touched by the acid.
Senior, the easiest way make that molten metal freeze quicker when you're pouring shot is to just submerge the part of the board you're pouring the metal on. It will begin to freeze before it hits the board and it should make smaller shot.
When I see the orange vapor from the nitric acid boils, I am reminded of the colors from smokestacks back in the early seventies in Detroit, and which you can probably still see in parts of China. I can also see that having copper as one of the inquartation metals helps you tell when the nitric acid has done its work.
you might want to remind folks that as you are making cloro oric acid that the base metals and silver that you may need more water for the various metal salts to dissolve in to as the acid may not be enough to dissolve in to so you may have excess unconsumed acid.
You said to add Sterling silver. Is it possible to use dirty silver such as silver buttons from relays??? Then you can process more materials with the same acid.
To correct my prior comment on making shot poured while inside a tall tower.. Shakespear's Era.. The molten metal was poured(same as you do) but from a great height onto fine screens which then fell into water. The height determined the size of the shot. Birdshot to BBs.
Thanks for posting these processes man. It is really weirdly satisfying to watch the process? hahaha Not sure what that says about me but, there it is Sreetips. Thanks again and all my best to you and your family. Pete Hollister, CA
Streettips I am very impressed with how far you have come in your skill and knowledge. I have watched you off and on for a long time now but this series and your skill earns my subscribe to you. I don't sub many channels unless there is something special about the channel you have gained my respect.
Sreetips, Geo from the forum has a video about Poor Man's Nitric. In the video he explained the importance of the volume of water used. His explanation was the base metals "need some place to go." From that I always premix my nitric acid with equal parts of distilled water when dissolving silver or inquarted gold. That seems to make the process move along faster and makes for a more efficient use of the reagents.
It would be nice if there was some sort of strainer that looks like a classifier before panning good to put down in the beakers so you can just pull it up out of there and make rinse cycles easier and take less time.
Hello Sreetips, please mount the acid dropper properly on your fumehood. The bucket tower looks extremely unsafe. This also gives you more space. I love your videos, keep it up!
sreetips once you've finished refining the gold will you be doing a video series on recovering the silver from the used nitric acid? also would it be worth you keeping said silver to use for your next batch of gold refining rather than using sterling silver that potentially has dirt and such mixed into it?
I know its 3 years later, but i just found your videos and im watching all of them. Love this content. You could get a bag clip style mount for ypur camera to mount it on the side of your box during refining to get the tripod out of the way.
Master, again, again, again, I watched your videos and I enjoyed it very much. The question I had is that the soils that contain gold and silver, can the silver be extracted from it with nitric acid, as you did, and with acid? Chlorideric recycled it as silver cotton? Your work is very professional, thank you
Hi sreetips, another great visual and detailed video. How have you amassed your beaker collection and do you have any recommendations for sites to purchase some? Thank you
This is an interesting approach but looks like it is critical marking on the gold scrap to be correct. Otherwise we may end with fine gold dust instead of this nice gold pile at the end. Waiting for the aqua regia part 4 👍
Which refining method is best for recovering the gold from military grade pin connectors? Thanks!! Your videos and teaching are the best and very much appreciated.
@@benwinkel I know but he has made many approaches to refining and I am trying to find out if after his new approaches would he find another method better.
You really help me when I’m depressed. I watch the video part after part and put my mind of all harmful feelings. Big thanks.
Sreetips, I started stacking up my metal ducting in my shop for my exhaust hood vent setup. I'm pretty excited. I also put my prospecting tools in a Rubbermaid tote today. Organizing. Those nitric acid boils produce some nice colors. I can't wait to learn more about silver and gold.
30:40 Another reason to use silver to inquart instead of copper is because it takes twice as much nitric acid to dissolve copper than it does to dissolve silver. Since nitric acid is expensive, Silver is the better way to go.

That gold came out perfect, proves what you said in the video, Patience is the key, it's a very rare commodity and we're all so lucky you have plenty - can't wait for Pt4 :-) No Rush though :-)
Great to see that nitric on a drip. This series just keeps getting more educational. I am wondering if you might be getting some gold in the nitric. Granules of alloy will need the silver dissolved out in order to be able to reach the silver deeper in each granule. Depending on how well the alloy is mixed in the smelt, you may not be able to do this without sacrificing some gold in the process. Maybe a gold test on your solution would be useful to find out if that occurs?
Gold doesn't react with nitric acid, and pure gold doesn't really dissolve. For the gold to dissolve in the nitric acid it would have to react with it, but since that is not happening (apart from maybe once ever 10^20 Gold atoms) this is of no concern.
One of the most interesting thing’s I ever did see 🙏
A video to show all your shop and equipment would be really cool. I wonder how you have your vent hood and exhaust set up.
Type “shop tour” and “fume hood” into the search block on my channel

Very excited to see this series progressing so quickly. You're spoiling us on so much great content released so close together! I have a question or two about efficiency in the use of your acids and rinses. Is there generally less waste if you process your metals in smaller batches, or do larger batches produce less waste, proportionally? Also, could rinsing the silver off the gold be done more economically (as far as nitric and distilled water use) if you were to pour the gold into a filter in a funnel and rinse it with your squirt bottle between each nitric boil? Thanks in advance for your answers, if you choose to give me some. As always, I'm a huge fan of your work!
If you're doing chemistry I'd say that wasting water is not often a concern. You use as much as you need to, of course you can use a little less water in between nitric acid washs, or even leave out washing with water in between, but you can't use less nitric acid. If you use too little nitric acid you don't get rid of all the silver / copper / base metals and that gets you impure gold.
What you could do to make it more efficient is perhaps stiring it with a magnetic stir bar.
Thank you Sreetips ,
Out of the hundreds of channels that I watch yours has to be the ones I look forward to the most!
I know right?!
amazing, the most detailed information about refining on youtube. would not watch anyone else
Thank you
What's more fun than watching sreetips refine a 25 OZT bar of gold? Watching him do it again! I'm on my second trip through this amazing journey, and man that brown gold looks great! I just purchased a copy of "Refining Precious Metal Wastes" by C.M. Hoke, and I am anxiously awaiting its arrival. It's not an inexpensive book, I paid $70 for it after tax, but it's going to be a very wise investment into my own knowledge. Whether or not I ever put it into practice is moot to me. I consider this type of knowledge to be valuable for its own sake. I do however, plan on setting up a lab of my own, and processing karat scrap and GF, GP jewelry. You are setting the bar really high with this huge batch of karat scrap refining. I'll be starting off with significantly smaller batches!!!
Where did you find her book?
You're awesome dude! Observing processes like this is why I got into chemistry!
20:00 I like to make ice blocks for my cooler for work out of the Sterilite 6 Qt Storage Box's that sell for roughly $1 from Walmart each. they take about 10 hours to completely freeze. i also thought that you should have a spray nozzle to spray down you board when making shot. also you should have a taller bucket or can to hold more water higher then the turkey deep fryer pot. i suggest a Plastic Drum with Lid - 30 Gallon, Open Top, Blue which you can get for about $25 bucks from craigslist.
A tall steel 55 gallon barrel
@@sreetips yeah!
Thank you for your service
Thank you, they were good to me and I was good to them.
This may not be the most professional channel but I love it's chaotic energy
I'll have to watch tomorrow, but I'm excited to do so! Thanks, Sreetips!

Check it!
Well, with all the reaching around the camera you do, supplying us with awesome shots , proves you are still flexible 😆 Thank You for sharing.
I'm sorry Mr. Streetips for getting so excited but this is what our young folk need to learn. Copper is one of the most exciting elements in my opinion and I love the oxidation states it produces, the colours are fantastic.
12:00 Have you thought about installing a 1/4"20 threaded insert into the side of your lab hood so you can mount the camera from inside the hood to: 1. Be able to pour the liquid away from you and 2. Have different angles of what is going on. The inserts are available at Home Depot or Lowe's for pretty cheap.
I’m just not that sophisticated yet
Well Sreetips i have been truly entertained to the point i was thinking of trying my hand at making my own gold bars. Your video is very informative even you show ur human sides of making mistakes. will continue to watch your future videos.
I love the fact that he makes mistakes, keeps them in the video, POINTS IT OUT lol, then he shows you how to recover if possible.
Man you are killing me with these mini series lol. Favorite bed time channel to watch. Great info man. If one were interested into getting involved what’s the best way to acquire the volumes of gold and silver to use for these?
I love every minute of this. About to jump on part 4.
I would like to send you some samples to refine
I only work on my own material that my wife and I find at local sales.
I love your work. Question, Could I send you some pics of precious metals in gemstone & rock? I'm in Nevada.
always a joy to watch, i would not watch any other refining video's streetips explains perfectly
ممنون بابت تمام زحمات شما ی سوال داشتم اینکه نحوه حرارت دادن به پودر طلا برای ذوب با هوابرش باید با هوای زیاد باشد یا کم و اینکه علت سیاه شدن طلا پس از ذوب چیست؟؟؟
Less air. Black is usually due to carbon.
Hands down the best teacher there is!
Use ammonia between the silver nitric acid rinses.. it cleans the gold beautifully and speeds up the silver separation.
It adds an unnecessary step to an already lengthy process.
To detect any traces of copper, just add some ammonia water into eluted acid-water sample (29:21). It does a very intensive indigo color from [Cu(H
2O)2(NH3)4]2+
en.wikipedia.org/wiki/Schweizer%27s_reagent
I always love the vivid colors of the metal solutions. The brilliant blue of copper and the emerald green of the first silver pour off are spectacular
The colour in both cases is due to copper though, Silver is colourless.
You should fit a portion of some of your beakers with a mesh screen to filter out liquids and such.
Beautiful caramel colored gold granules , sreetips, and a. testament to your exacting constant calculations. I'm spellbound by these processes, and I never get weary of seeing them. You've got me seriously considering doing some of these experiments myself, it looks like a fairly expensive layout for glassware, vacuum pump, heating/stirring plates, and fume evacuation booth, but the expense will be recouped rather quickly once I get things rolling. You make this look easy, but I know that it's not. You can blow the whole thing if you foul up at any step of the way. Thank you for sharing your successes and your failures with us, the astute viewer will take notes, and if they attempt to recover and further refine gold and silver themselves, watch out for the troubles that you experienced. Thank you again, for sharing your knowledge and expertise with us, I appreciate it very much!...... WH
Thank you Wade
Really like your channel. You make refining even more cool and interesting than I already found it. Nice one buddy. 👍
Love the videos. I really like how you explain what your doing and why as you go through the process. Thank you for all the knowledge.
But the blue tint is from Cu(NO3)2: the AgNO3 produces a clear solution. So rinsing until clear does not necessarily provide a silver-free solution. Do the Aqua Regia and the small quantity of silver should precipitate out as AgCl and can be collected via filtration when filtering the Aurochloric acid solution.Cheers
I don't know anything about chemistry, only what I watch on TH-cam. I watch a few others that put an excess of silver in, so that they do not need to do as many hot nitric acid boils. From what I understand that is because with so many silver atoms surrounding the gold atoms you can get to all of them with far fewer boils. Also, they are not getting to three-nines-fine either, and they don't care too much about the silver afterwards. Your electrolytic cell is unique, and probably contributes significantly to the overall process. Always fun to watch!

35. C. Filter solids out
36. D. Cement on copper
37. E. Melt into shot
38. F: run through silver cell w electricity charge crystallize in the silver out of the liquid

42. B. then “incremental nitric acid dosing”
43. PART 4: VIDEO th-cam.com/video/V2IZPheNl5A/w-d-xo.html
44. Take the included gold that is already been, “nitric acid boiled” and add hydrochloric acid with 23 g of brown dust so that the level goes up to 1000 mL of hydrochloric acid on the large 5000 mL beaker with the open top. Start your boil.
45. incremental nitric acid dosing: use a dropper to add a few drops of a time to the hydrochloric acid boil
46. this forms “aquaregia” and dissolves our gold
47. Add just enough nitric to the hydrochloric acid so that you just barely dissolve the gold but there’s not too much extra nitric acid to deal with later when we go to precipitate the gold
48. sulfuric acid: add a few drops to make sure it takes out any letter any copper that’s in the solution
49. vaccum flask: Is suction tube to pull off the pure solution out of the original nitric boil bigger which has had sediment fall out the bottom of it. This allows you to get the pure liquid solution with a gold in it and leave the sentiment behind
50. filter flask #2: number two paper filter: flat top funnel with micro holes going into vacuum flask number two
51. Next step: precipitation: 5000 mL large open beaker with a cylinder in the bottom
52. Litmus paper: “standis test”????: typical of this paper in Cold Solutions, then take a dropper Full of ?????.., Drop on litmus paper and it should turn black
53. Sodium metabisulfite: start adding scoops of white powder chemical into the gold solution in the large beaker to precipitate out the pure gold. When powder hits the orange solution it turns black as it precipitates out the gold like this picture below
54. PART 5: refine one more time and then Milton to a 25 Troy ounce gold bar th-cam.com/video/3t5xhPfIlfQ/w-d-xo.html

always an interesting watch , I end up ignoring the tv when I'm playing your videos ROCK ON !
was going to ask a dumb question, but you covered it at 53:00 ,my question was you got a good surface area by melting the gold into granular , then used nitric acid to remove the base metals and silver, why go further with aqua regia HCl + HNO3, why not just melt it into the gold bar? so my guess is if you melted now you might have around a 23k gold bar.
The gold could have been melted but the problem is lead. If lead is present, even in trace amounts, it ruins the malleability and ductility of the gold. Refining with aqua regia is the only way to get the lead out completely
Excellent video. This could be a teacher’s aide video on how to do this. It’s that good. Can’t wait for part 4.
Im glad you answered the quesiton about why you use silver instead of copper in the video. Its a question I'd been pondering but hadnt yet asked. It might have been hard to find in the comment section. Copper is a lot easier for me to find than gold, since I deal with computer scrap. Im still a year away from any refining though. Its been 30 years since I was in a chemistry lab at university, but I reckon I can manage it now that my son is finishing up a chem degree :)
Piece of sanitary 316L ss, schedule 10, 12" pipe- 36" to 48" long to cool your pellets. Your beads just need a little more travel time through the water to keep from re-fusing on the bottom.
Testing for Silver in solution with HCL is very clever but remember that HCL concentrated will also dissolve some Silver chloride . redissolving your gold in aqua regia will defiantly
give you 99.9 purity good work . You do know there are much faster and easier ways to do this . I do compliment you an your patients
Greetings! Nice videos. I've watched several so far. I spent 5 years total on USS MacDonough and USS Wm V. Pratt, which were the same class as the Farragut, back when they were still designated DLG's. :-)
I’m familiar with both. Thanks for your service!
USS Farragut, Salute. I was on board the USS Proteus, AS 19, Sub Tender, was welder and damage control, Hull Technician
I was MM2 on Farragut.
Why do you add the excess nitric to silver just to consume the nitric acid? At around 24:30 in the video.
If all you want to do is consume the nitric, couldn't you do something less expensive? I think I'm missing something here.
The silver in that jar must be dissolved in nitric. First step in refining it to high purity.
Silly question: Are the glass plates that you put on top of the beakers there solely to prevent foreign material from falling inside or is there an additional purpose?
They funnel the condensation back into the beaker and also keeps stuff out.
@@Card_Asylum That makes sense. Thanks.
@@IMDunn-oy9cd no problem. I only answered cuz I had the same question on another channel and they answered before I asked.😜 ✌️
Greetings to my dear teacher
The metals palladium, platinum and rhodium are soluble in aqua regia solution. Now what happens if I use iron to deposit them? In my country zinc is very expensive .
waiting for your answer !!!
I’ve never used iron I don’t have any experience
Any acid in solution would oxidize the Iron forming ferrous ions, which would end up rendering ferric ions. The latter hydrolizes unless the pH is below 3. The product is insoluble ferric hydroxide Fe(OH)3. On heating it gives Fe2O3, contaminating the gold cement. You don't want this.
I don't know the cons if vou decide to use a strongly acidified solution.
If you stirred slowly with a glass stir stick you could dissolve more in each batch due to the contact points of each piece of gold touching each other leaves some surfaces not touched by the acid.
Good point, thank you
Awesome its a lot of work to do such a big amount of Gold i can see why you don't often do large amounts now Great Vlog thanks
Senior, the easiest way make that molten metal freeze quicker when you're pouring shot is to just submerge the part of the board you're pouring the metal on. It will begin to freeze before it hits the board and it should make smaller shot.
Nice job looking forward to seeing the next video. Thanks.
Thank you for your service and the awesome videos.
Thank you
When I see the orange vapor from the nitric acid boils, I am reminded of the colors from smokestacks back in the early seventies in Detroit, and which you can probably still see in parts of China.
I can also see that having copper as one of the inquartation metals helps you tell when the nitric acid has done its work.
The brown flakes of gold you can see after the silver has been dissolved make me think of Cocoa Pebbles. 😁
take a bite
For real lol
@@aaronbuckrell6505 wa
you might want to remind folks that as you are making cloro oric acid that the base metals and silver that you may need more water for the various metal salts to dissolve in to as the acid may not be enough to dissolve in to so you may have excess unconsumed acid.
I always enjoy your videos. You explain things very well! See you in part 4!
You said to add Sterling silver. Is it possible to use dirty silver such as silver buttons from relays??? Then you can process more materials with the same acid.
To correct my prior comment on making shot poured while inside a tall tower.. Shakespear's Era..
The molten metal was poured(same as you do) but from a great height onto fine screens which then fell into water.
The height determined the size of the shot.
Birdshot to BBs.
I think shot towers still exist.
I still don’t comment much, but that shoutout to the young future refiner is too cool. 😎👍🏻
Very well done. This is a brilliant presentation.
Thanks for posting these processes man. It is really weirdly satisfying to watch the process? hahaha Not sure what that says about me but, there it is Sreetips. Thanks again and all my best to you and your family.

Hollister, CA
Same to you Pete
Streettips I am very impressed with how far you have come in your skill and knowledge. I have watched you off and on for a long time now but this series and your skill earns my subscribe to you. I don't sub many channels unless there is something special about the channel you have gained my respect.
Thank you!
Love your work.3 washes is the rule in chemistry.keep on keepin on!
Sreetips, Geo from the forum has a video about Poor Man's Nitric. In the video he explained the importance of the volume of water used. His explanation was the base metals "need some place to go." From that I always premix my nitric acid with equal parts of distilled water when dissolving silver or inquarted gold. That seems to make the process move along faster and makes for a more efficient use of the reagents.
Hey have you considered refining waist solutions from a industrial X-ray company?
I find your videos very interesting and quite relaxing.
It would be nice if there was some sort of strainer that looks like a classifier before panning good to put down in the beakers so you can just pull it up out of there and make rinse cycles easier and take less time.
Your content sir is so informative.. I've learned a lot about refining gold.. Try teaching chemistry class Sir. 😅😅
I've seen the video of you doing SIM cards but my question is how much gold is in circut board and is it worth refining it?
Can you use copper and what is the difference in processing it?
The SIM card yield was pitiful. Circuit boards probably are just as bad
I'm a new be scrapper, learning so much , thank you, can rain water be used for rinsing
I was going to experiment with condensate filtered from my air conditioner. I’m not sure about rain water
Great video sir! Very interesting and informative, and fun to watch. Thank you!
Hello Sreetips, please mount the acid dropper properly on your fumehood. The bucket tower looks extremely unsafe. This also gives you more space.
I love your videos, keep it up!
sreetips once you've finished refining the gold will you be doing a video series on recovering the silver from the used nitric acid? also would it be worth you keeping said silver to use for your next batch of gold refining rather than using sterling silver that potentially has dirt and such mixed into it?
Hello from Melbourne, Australia.
Love your channel 😁🤝
Hello Melbourne!
Respect for taking your time and making sure all the base metals were completely gone from the gold.
Thank you, but I didn’t make it. You’ll see in part 4
Every time I see you swirling nearly 50k in gold in a giant beaker, I hope the glass doesn't have an issue. :P That looks like so much fun
I know its 3 years later, but i just found your videos and im watching all of them. Love this content. You could get a bag clip style mount for ypur camera to mount it on the side of your box during refining to get the tripod out of the way.
The fumes would quickly destroy the camera
@@sreetips i didnt mean mount it inside, i ment mount it on the side but on the outside edge only to remove the tri pod.
Got it, that would be beneficial.
Master, again, again, again, I watched your videos and I enjoyed it very much. The question I had is that the soils that contain gold and silver, can the silver be extracted from it with nitric acid, as you did, and with acid? Chlorideric recycled it as silver cotton? Your work is very professional, thank you
Yes, nitric acid will dissolve out the silver. The gold, not being very soluble in nitric acid, will remain undissolved and get left behind.
@@sreetips tanks my teacher 🙏🏻
@ 6:50 it made me thinking: " ...borderline between a genius and a mad man"
Hi sreetips, another great visual and detailed video. How have you amassed your beaker collection and do you have any recommendations for sites to purchase some?
Thank you
I bought all my glassware on ebay
hoping for a new video today. We love them Thank you for keep making videos
This is an interesting approach but looks like it is critical marking on the gold scrap to be correct. Otherwise we may end with fine gold dust instead of this nice gold pile at the end. Waiting for the aqua regia part 4 👍
Part 4? I thought this was *Street Tips* for the entire video even after telling myself it's not. Love the content.
Thanks for sharing your knowledge. I really enjoy your videos
Which refining method is best for recovering the gold from military grade pin connectors? Thanks!! Your videos and teaching are the best and very much appreciated.
He's made a video on that
@@benwinkel I know but he has made many approaches to refining and I am trying to find out if after his new approaches would he find another method better.
