I love watching u refine gold and silver because you r the biggest and best channel to do refining, we all learn so much from watching u because it's amazing to watch.
My favorite part is when you first start melting in the dish. That first layer of crust as it melts looks awesome and beautiful all at the same time! Thanks again for continuing your videos, Mr Sreetip!
Thank you for having taught me enough so far that I know what inquartation is for. It seems at first counter-productive until you understand the next chemical steps.
Tell me why everytime i see you post a new video i zone out and watch it like a little kid watching cartoons. Ive got a collection of scrap gold and boxes full of silver coins/cups/flatware of all types.i hope to learn enough from your videos to figure out how yo rifine my heavy metals to its purest form...and then...well i guess start collecting and do it all over again lol
Coins are almost always better as the coin than as scrap. They will follow there metal content without refinnning, often beating it for the collector value.
Oh man. Looooong day at work, needed some relaxation. Nothing better than some fresh sreetips to soothe the soul. I studied a bit of chemistry back in the day and I loved nothing more than practical time in the lab. It was always so rewarding to watch what you know in theory actually happen. I know it’s cumbersome to record and to maintain some degree of safety, but your vids really scratch that old chemistry lab itch for me! We really appreciate you sharing this. Thank you sir!
I used to milk cows when I was a kid at my father's dairy back in Mexico, everyday when I get to the farm I would put my dad's old shirts over my school uniform to start milking cows kind of like a coveralls for kids and the one that last me the longest was green with white squares on it!! My mom being American brought here when I 16. I didn't even know what gold was back then..anyway, I grew up. And learned about gold. you are the G.O.A.T. as we call them in sports, that precipitation was absolutely the greatest thank you!!
I've been working my a$$ off and missed your production...Im sitting here with some Pistachios (Chili) and a cold beer after work, and need to say I really appreciate the new lighting arrangement you used to show how cool it looks when you precipitate your gold into solution. And really cool when you added the SMB and it looked like angel hair 😇 as you precipitated your gold out of solution. That was awesome 👌 Thank you for a great video, as always 😬
I've been really getting itno your videos lately, and nothing quite as informative on youtube for this stuff. Well done to you. I would love to see a breakdown of what it costs you to break down this scrap to pure gold and silver. Mabe, including how you got the scrap jewelery, cost of it, cost of chemicals, and what it's worth after refining. I think that is something a lot of us would find great interest in. It would definitely be a great part 2 to this video
Sounds like a lot of work. I don’t really track expenses for each batch. And when it’s done, i think it would be foolish to convert the highly valuable gold back into paper dollars that are going down. I’d guess a refining of this size would cost less than a hundred bucks. Not counting the metals.
Been out of the Navy since '97. Never got the oil lab experience I needed to help with exams. Been a long time since I've heard/said/logged "clear and bright"
I think..That first reaction was so great, because you cleaned everything so well. You said you went overboard with the nitric boils/cleaning. That first SMB reaction says maybe, you didn't.😁
I agree with all the comments it never gets old. You are the master. Everything is so seamless and precise. Ive done four refines now and two of them i boiled over lol questions for you ..Is it still fun for you? What is you favorite part? How long have you been into noble metals? Without getting too personal and if you care to share what did you do before this is it full time for you? Sorry for all the questions out of the channels i follow you are the only one i am curious to know..
This was begun as my hobby. Then I posted a short video for kicks. A year later I seen my video on a search engine. Logged in to my RUclips and the video had 92k views and 1600 subscribers. But lately, it’s become more of a chore to create new content. Someone once said that if you turn your hobby into your work, then it becomes just that, work. My favorite part is precipitation - that never gets old.
@sreetips the chore part being recording itself or just trying to come up with different ways and techniques? Because imo it's never gets old you could do the same thing over and over again. Thankyou for your replies.
Adding the SMB was so pretty! Allowing the Brownian motion and convection currents in the vessel mix the chemicals. Looks like something from a sci fi movie! Like golden clouds floating around. Stunning! You can use 2 filter papers at once if you think the paper might break. Can use the same size twice or use a finer one and a more coarse one, with the coarse one on top of the finer one. EG use a 40 on top and a 44 underneath. Have you ever swept the floor, the inside of your hood etc and seen what may have deposited on the surfaces etc from splashes/fumes? Maybe worth checking the filter of your hood to see what precious metals may have evaporated in gaseous form? Have you ever tried to extract gold from sand/soil/tailings from maybe a gold prospector? Could be fun!
Wow mr Sreetips this is an awesome ✨️goldbar ....you proces of doing this is great....miss Sreetips is going to be very happy😂🎉greetings from the Netherlands 🇳🇱✨️👍
You're work kicks ass man! Thank you :) Re: Land of Chem, Palace of the Goldsmith site visit Ep.? This off Nile structure has seven chambers with massive door jambs, chemical staining, and vent holes at the top. Sounds more like a Palace of the Gold Refiner to me.
Septic means sevenfold, septic sludge looks like refined gold sludge, seven rings to bind them in a cycle of heavy metal extraction and refinement. Mordor was real.
Love your setup. Been watching for years and just decided a month ago to put it to practice myself. Just still confused over filter papers. Seems everyone has a preferred paper but can't get an answer to what is best for each situation. Was wondering what you recommend. And also any suggestions on Nitric, Hydrochloric, and sulfuric sources best bang for the buck??
Is it possible that the gold which came out of the solution at 23:50 was especially pure? Whether it is or it isn't, just a hair under $12k for the bar and the baby.
One time when you are melting the gold powder down you should stop half way. It always looks like a cool sculpture. If it remained as 1 piece I am sure it would look epic!
Would putting the sterling through a ultrasonic jewelry cleaner work as well as heating it to get rid of the oils/gunk /etc., or do you really need to heat it up to thoroughly clean it?
Ultrasonic would be helpful, but not necessary. One of my mentors had a saying, “the three most important tasks when dealing with scrap gold are; incineration, incineration, and incineration.
Sreetips thanks for all the knowledge and entertainment that you have given us over the years. I have one question! What is the average per ounce that it costs to refine gold? Thank you so much if you can answer this and feel free to do so privately.
Great video , I’m going to keep stockpiling all gold containing components of everything I strip down until I have around 50kg then get it refined for the gold
So amazing, when you do that first aqua regia and you don’t get the “forbidden orange juice” after adding the ice, but instead just get more dilute chloroauric acid.
That first SMB round was like watching storms on Jupiter, or the most expensive coffee ever poured. But I've got to say, Sir, that time-lapse of the reduction after the second aqua regia round gave me some instant anxiety 😂 Not that you could actually damage the gold, but seeing it reduce down to tar like that made me think the video was going south from there!
@@movietime111 sometimes people try to use soft solder to do repairs. Soft solder contains tin and lead. The only way I know to remove the lead is to add a few drops of sulfuric acid before filtering. I add sulfuric even if I don’t suspect the presence of lead. It’s cheap and doesn’t hurt the process at all. I understand that adding sulfamic acid also works because it turns into sulfuric acid upon adding to the gold solution. Lead, even in trace amounts, ruins the malleability and ductility of the gold.
So if the gold is .999 fine after the silver and base metals are pulled out why keep refining it if you can alrea get top dollar from the buyer ? Unless it's just for the video
Awesome vid!!!! The sulfuric acid used, do you have an over the counter brand you go with or is this unused (new) battery acid? Tertiarily (or) do you purify and concentrate the sulfuric acid via distillation or boil off with hydrogen peroxide (Caro’s Acid) process? Currently I purchase a 98% product that is clear and i believe is the azeotrope and only H2SO4 and diH2O. Staying away from purple drain cleaners and buffered Acids. Amazing work! Thanks!!
I've been watching since around 2013-2014, so you could say I'm a long time fan! What part of the navy were you in? I'm currently enlisted as a nuclear machinist mate
About how many uses do you normally get out of a melt dish? I ask because I want to compare to the crucible usage rate for an open-top furnace (something like the Tabletop Furnace Company's QuikMelt Pro series, top-loading with a close-fitting crucible)
Inquarting doesn't care as much about the contamination from the silver and base metals (and their compounds), presumably. What's the warning sign to retire a melt dish that you're using for inquartation?
that is worth £9254.35p in the uk today mr sreetips nice one as always good cook twice over here a question sorry if sounds stupid ok you wash the gold twice to be more pure so if you where to do it a 100 times over what would be the result oh ye gold master sorry for my ignorance ????
@sreetips ok then, I noticed the color change of the gold chloride from yellow to orange tint more you refine from 99 to 999 to 9999 fines, But theirs a time limit on heat making the syrup color means the nitric evaporated out. Ok Thanks Sreetips ❤️
There probably wasn’t much nitric to begin with. I was doing something else and wasn’t paying attention. All the nitric was gone well before it turned dark.
@sreetips It happens to me , my mind gets me to thinking about other projects or things that need attention, then I forget. I guess we all need to set alarms ⏰️ Thanks for explaining what occurred. Have Great Weekend Sreetips ❤️
I love your channel sir... I wanted to ask you how did you get started in chemistry I noticed you were Navy. Thank you for your Service I'm new to the channel but you have a regular subscriber now!!
Excellent, thank you. I used to just resell all the scrap gold. Then I began to wonder what they did with it after buying the gold from me. The rest is history.
Awesome video as usual. I've seen you do this process many times, but still fascinated by it. I'm curious of you had a background in chemistry before your refining career?
Hey, would you happen to know how much power your refinery kit pulls? Im building a solar shed to do this in and i need an idea of how much power I'll need, thanks.
Have you noticed any of the gold on your omega watch being removed from your years of refining? Doesn’t seem likely given your example with your wedding ring but I’m just curious. You rock Sreetips!
If you were either get a melt dish with holes under the lip or drill say four holes ( you could determine the size of the pellets of metal by altering the hole size ) you might get a finer product to add to the acid .
Any tips on how to free the silver content from my mixed metal? It's a bunch of melted solder, and costume jewelry with some silver content. I tried basically grinding up zinc pennies and scraping slag, but even with the zinc, and torching it all to Zinc Oxide, I'm still left with some base metal, although reduced, probably Tin, as I used lead free solder, can't "purify" it. Thanks for any tips that hopefully dont involve looking like I cook meth
If it was mine I’d dissolve in nitric, allow it to settle completely, draw off the clear liquid with the silver in it, then cement it on copper. If those metals are in with the silver, then they will stay in solution and only the silver will come out of solution on the copper. That’s what I’d try if it were mine. No guarantees. Especially if there’s little to no silver present.
@@sreetips I actually added a handful of Canadian 80% silver quarters basically thinking that I might be able to attract silver to other silver, didn’t work, but I put in a very good handful, I’ll try nitric acid, I just am honestly scared to work with it
Don’t use zinc, it’s high up in the reactivity series and it will cement out everything including copper and iron. And do t use too much nitric. It only take about 1ml nitric to dissolve I gram of silver. If I suspect too much nitric, I add some more silver then boil until all the fumes are gone and there’s still some undissolved silver in the bottom of the beaker. But a tiny bit of nitric is required for cementation reaction.
i've been wondering. does the the liquid state feel heavier than normal? and same with the powder? like can you tell the difference between the 3 states?
A solution with gold in it will feel heavier than the same volume of liquid (acid or plain water) with no gold in it. The gold powder is very heavy, same as the weight of the gold bar.
@sreetips At 35:53 I see you still have pieces of gold powder on left dish and some on the right dish. Also a bit of gold powder on the edge of melt dish. That bit will be dropped on the floor at 36:06. You are very careful with all that rinses and boils to not loose a drop of gold solution but here quite a lot of material is potentially wasted. On your melting table and gold bar jig I can see many small round droplets of pure gold and possibly silver. Maybe it is time to collect and process those tiny bits 🙂
What size micron is the filter paper that you use and do you have a preference to a specific brand or type? So for all these questions but I've been following you for a while and I have free time on my hands and I handle a lot of computer parts and thought that this would be a fun pass time to get into.
For all around general purpose, everyday ordinary filtering, I prefer Whatman number two medium flow filters. I don’t know the micron size. Cooling the solution before filtering cinches the pores up and filters out finer particulate. The only other time I need different filters is when filtering particulate from sulfuric acid filters. Sulfuric acid will dissolve paper so I use fiberglass filters.
I think we are about to find out how much nitric it takes to dissolve the striped shirt! I thought it was a goner for a while there. That Walmart time lapse watch is still going strong too. Not as shiny though. 😊
Hello Sritips can you show me your video about 6x refine a gold and remove any lead or any other impurity expect using sulfuric acid, i ever hear that you can remove impurity using sodium carbonate o or soda ash?
I add sulfuric acid before filtering to precipitate out any lead that may be present. I add sulfuric even if I don’t suspect the presence of lead. It hurts nothing, costs almost nothing, and removes all the lead as lead sulfate during filtering. Sodium carbonate is a type of flux used to clean the melt dishes. But I don’t think it removes impurities. The only way I know of is to refine the gold with Aqua Regia.
@@sreetips Yes i know you ever say that adding sulfuric acid is cost nothing from gold refine forum but there is one more chemical that could use gor remove any impunity like copper, lead or any other metal, its called sodium orthophosphate.
You taught me to do this and refine the silver in my silver, yet it still NEVER gets old watching you work...keep it up!

Thank you for the 1064°C warm welcome. Perfect timing for chowtertainment! Thank you Sir!👍👍🤟
I love watching your videos they are so therapeutic for some reason and informative thank you for sharing your skill and hard work with us all
Thank you
You could make 10 million of these videos and I would watch every one of them. Good stuff.
I can't think of a more beautiful colour than gold dissolved in Aqua Regia! The more orange the better.
It’s a darker shade when it’s hot. Then it turns lighter orange as it cools.

How about BS&W (bottom sediment and water).
Amazing video. Especially the SMB shots showing the precipitation.
Thank you for the outstanding experience
Excellent video thank you 😊 wish everyone watching could see how brilliant the colors really are !!!
Man that was awesome when you dropped that first spoon of SMB in real slow. What a cool reaction.
I miss the silver cells videos. Congrats on the content, by the way.

Love watching the gold and silver getting mixed together
That was a beautiful thing, watching that crucible with the gold mountain turning into gold lava made me cry.
There was a small fleck on the side of his dish that flew away. That almost made me cry
@troutmaster3 I’ll get it when I sweep the area.
I wonder if using a tall temperature resistant measuring cup would work better for drying and transfering the gold to the melt dish?
I just love the blue tones of silver nitrate. Shiny gold is nice too.

10 is .635
14 is 1.265
18 is 1.9
One time when you are melting the gold powder down you should stop half way.
It always looks like a cool sculpture. If it remained as 1 piece I am sure it would look epic!

I have a Question- 🙋♂️ Can you put Nitric Acid in directly on the Karat gold and pull out base metals without melting the silver in it?
No
That was sure pretty when you were melting it down in a clean melt dish. That would be why we like to see it. Thanks for the video sir.
Great video , I’m going to keep stockpiling all gold containing components of everything I strip down until I have around 50kg then get it refined for the gold
Wow it really looks good. It's amazing how you can do that
So amazing, when you do that first aqua regia and you don’t get the “forbidden orange juice” after adding the ice, but instead just get more dilute chloroauric acid.
At 23:55, why not let the gold boil out of solution? What is the benefit of SMB and gold refining waste?
Without the reduction by SMB, you don’t get gold metal. It stays as aurochloric acid.
Because not all of the gold will come out of solution.
That round Jesus pendent was pretty cool wish I could have bought that off you. Did you recover the tiny diamonds?
It was broken and the back was all bent up. Scrap
Am I right that silver nitrate solution is colourless, and the blue colour is from copper sulphate?
Copper nitrate, actually.
Yes, the blue is actually copper nitrate.
@@sreetips of course, silly me.
Something about watching the SMB turn into gold powder. It's psychedelically mesmerizing.

how often do you replace your crucibles, this one seems to be fairly new...... ie how many gold melts do you usually get per crucible ?
About ten or so
have you ever done a sweep of your gold room to see if there is good in the dust? keep seeing splatters and bits of powder on the videos
Yes

I use Rooto Professional Drain Opener from Ace Hardware. It’s about twenty five bucks per gallon. The data sheet says it’s 93%
What are the orange fumes that come off of the inquarted gold in the process of taking out the silver ??? is that silver oxide?
No, it’s nitrogen dioxide.
So if the gold is .999 fine after the silver and base metals are pulled out why keep refining it if you can alrea get top dollar from the buyer ? Unless it's just for the video
I think is more something like .98-.995.

The watch in the fume hood is some sort of sports watch. I added a battery and it’s been working fine for about a year.
Sorry if this is a stupid question, but why add silver to the gold in the first step if you are just going to use acid to remove it in the next step?
So the acid can penetrate
About how many uses do you normally get out of a melt dish?
I ask because I want to compare to the crucible usage rate for an open-top furnace (something like the Tabletop Furnace Company's QuikMelt Pro series, top-loading with a close-fitting crucible)
I can use the same melt dish about ten times, if I melt only pure gold in it. If I end up melting lower purity then I retire it to inquarting.
Inquarting doesn't care as much about the contamination from the silver and base metals (and their compounds), presumably.
What's the warning sign to retire a melt dish that you're using for inquartation?
If I see blue or green in the borax glaze then I won’t use it to melt high purity gold.
20:58 Did some gold go back into the solution there?
No, it was probably PGMs or iron that made it yellow. HCl boil can put a little back in solution if there’s still a little excess nitric present.
that is worth £9254.35p in the uk today mr sreetips nice one as always good cook twice over here a question sorry if sounds stupid ok you wash the gold twice to be more pure so if you where to do it a 100 times over what would be the result oh ye gold master sorry for my ignorance ????
Turning the gold chloride to a syrup , what does that do ? Does it condense the gold ions together ? Thxs Sreetips ❤
I evaporate it down to drive off excess nitric. But let it evaporate too long so that some of the gold came out of solution.
@sreetips ok then, I noticed the color change of the gold chloride from yellow to orange tint more you refine from 99 to 999 to 9999 fines,
But theirs a time limit on heat making the syrup color means the nitric evaporated out. Ok Thanks Sreetips ❤️
There probably wasn’t much nitric to begin with. I was doing something else and wasn’t paying attention. All the nitric was gone well before it turned dark.
@sreetips It happens to me , my mind gets me to thinking about other projects or things that need attention, then I forget. I guess we all need to set alarms ⏰️ Thanks for explaining what occurred. Have Great Weekend Sreetips ❤️
I love your channel sir... I wanted to ask you how did you get started in chemistry I noticed you were Navy. Thank you for your Service I'm new to the channel but you have a regular subscriber now!!
Excellent, thank you. I used to just resell all the scrap gold. Then I began to wonder what they did with it after buying the gold from me. The rest is history.
Awesome video as usual. I've seen you do this process many times, but still fascinated by it. I'm curious of you had a background in chemistry before your refining career?
No, my chemistry knowledge is all self taught. I have no formal chemistry training. Just an intense desire to succeed.
And I love refining gold and silver.
Hey, would you happen to know how much power your refinery kit pulls? Im building a solar shed to do this in and i need an idea of how much power I'll need, thanks.
My electric bill last month was $178
@@sreetips so it must not need alot of juice then, awesome! Thanks alot man I appreciate it
So neat and clean.
Have you noticed any of the gold on your omega watch being removed from your years of refining? Doesn’t seem likely given your example with your wedding ring but I’m just curious. You rock Sreetips!
No, it taking a licking and keeps on ticking.
Hello,have you ever done a video on your vacuum system?I think that would be interesting.
Yes, search for How to Build a Reliable Vacuum System.
If you were either get a melt dish with holes under the lip or drill say four holes ( you could determine the size of the pellets of metal by altering the hole size ) you might get a finer product to add to the acid .
Hello Mr. Sreetips. Do you sell your cement copper or is it worthless?
It’s pretty much worthless.
Any tips on how to free the silver content from my mixed metal? It's a bunch of melted solder, and costume jewelry with some silver content. I tried basically grinding up zinc pennies and scraping slag, but even with the zinc, and torching it all to Zinc Oxide, I'm still left with some base metal, although reduced, probably Tin, as I used lead free solder, can't "purify" it. Thanks for any tips that hopefully dont involve looking like I cook meth
If it was mine I’d dissolve in nitric, allow it to settle completely, draw off the clear liquid with the silver in it, then cement it on copper. If those metals are in with the silver, then they will stay in solution and only the silver will come out of solution on the copper. That’s what I’d try if it were mine. No guarantees. Especially if there’s little to no silver present.
@@sreetips I actually added a handful of Canadian 80% silver quarters basically thinking that I might be able to attract silver to other silver, didn’t work, but I put in a very good handful, I’ll try nitric acid, I just am honestly scared to work with it
Don’t use zinc, it’s high up in the reactivity series and it will cement out everything including copper and iron. And do t use too much nitric. It only take about 1ml nitric to dissolve I gram of silver. If I suspect too much nitric, I add some more silver then boil until all the fumes are gone and there’s still some undissolved silver in the bottom of the beaker. But a tiny bit of nitric is required for cementation reaction.
I love watching it melt😮😊 thanks sreetips
Kinda wonder if that bug became a Ever Lasting thought full Haze!!!; )😂
Sir , Are you using concentrated or dilute sulphuric acid
The safety data sheet say 93% sulfuric acid.
Was all that jewelry in the beginning all pure gold? Or was any of it gold plated?
It was all karat gold. No plated pieces were in there. Gold plated won’t work with this process.
@@sreetips Oh ok, thanks!
How much more pure is this final refined that if you had just ended after initial nitric and hydrochloric rinses
990 to 995 after the nitric boils.
i've been wondering. does the the liquid state feel heavier than normal? and same with the powder? like can you tell the difference between the 3 states?
A solution with gold in it will feel heavier than the same volume of liquid (acid or plain water) with no gold in it. The gold powder is very heavy, same as the weight of the gold bar.
Why does the gold solution look darker, almost reddish orange when hot, and lighter, more yellow after cooling, even before diluting with ice?
I don’t know, but that happens just about every time.
Not sure what kind of mind came up with this process. I am torn between twisted and genius.
Great vid as always. Have you ever experimented with inquarting with copper instead of silver?
He’s done that at least once. Go through his video library
Yes, videos posted.
@sreetips At 35:53 I see you still have pieces of gold powder on left dish and some on the right dish. Also a bit of gold powder on the edge of melt dish. That bit will be dropped on the floor at 36:06. You are very careful with all that rinses and boils to not loose a drop of gold solution but here quite a lot of material is potentially wasted. On your melting table and gold bar jig I can see many small round droplets of pure gold and possibly silver. Maybe it is time to collect and process those tiny bits 🙂
I gather those with a card and brush and add them to my temp waste container for later recovery.
Where do you recommend getting your beakers and the vacuum ones from? And a good vent hood. Aloha from Hawaii 🤙🏾👍🏽
Aloha Hawaii, I ordered mine from eBay.
@@sreetips thank you for your help
What size micron is the filter paper that you use and do you have a preference to a specific brand or type? So for all these questions but I've been following you for a while and I have free time on my hands and I handle a lot of computer parts and thought that this would be a fun pass time to get into.
For all around general purpose, everyday ordinary filtering, I prefer Whatman number two medium flow filters. I don’t know the micron size. Cooling the solution before filtering cinches the pores up and filters out finer particulate. The only other time I need different filters is when filtering particulate from sulfuric acid filters. Sulfuric acid will dissolve paper so I use fiberglass filters.
@@sreetips thanks for your time and help with this. 🤙🏾 Have a awesome day
I think we are about to find out how much nitric it takes to dissolve the striped shirt! I thought it was a goner for a while there. That Walmart time lapse watch is still going strong too. Not as shiny though. 😊
Hello Sritips can you show me your video about 6x refine a gold and remove any lead or any other impurity expect using sulfuric acid, i ever hear that you can remove impurity using sodium carbonate o or soda ash?
I add sulfuric acid before filtering to precipitate out any lead that may be present. I add sulfuric even if I don’t suspect the presence of lead. It hurts nothing, costs almost nothing, and removes all the lead as lead sulfate during filtering. Sodium carbonate is a type of flux used to clean the melt dishes. But I don’t think it removes impurities. The only way I know of is to refine the gold with Aqua Regia.
@@sreetips Yes i know you ever say that adding sulfuric acid is cost nothing from gold refine forum but there is one more chemical that could use gor remove any impunity like copper, lead or any other metal, its called sodium orthophosphate.
Ok, thank you.
Awesome video nice gold bar and bead thanks for sharing sreetips
