Agreed! There is something so satisfying about watching it. When I first started watching this channel, I used to stress when he would decant gold and clearly you could see small amounts of it being washed into the waste. After watching for a while, I figured out that it does not matter, as that gold will be recovered eventually. The same with filters, etc. I'm sure he loses a tiny amount up the fume hood, but probably close to 100% of all other "lost" gold gets recovered eventually.
It must be so amazing to have such know-how at your command in order to create such beautiful pieces of gold and silver. Thanks so much for these videos, Senior Chief!
Just made my Saturday night...a Streetips video! God, I remember when I was young/cool and had a life 🤣😂 Cheers from your neighbor to the north Brother
It might be worth including a short clip of the safety gear you put on at the start of these processes. This might save the life of somebody following in your footsteps.
Boiling SMB? that's new to me. I need to go rewatch last season, Lol. I missed something. Sreetips, I've been a viewer for maybe just under 3yrs, now. I haven't seen anyone explain things the way you have. Seriously grateful!
@@aaabeverages7152 only if he used ferric sulfide, smb doesn't have iron as a part of its structure. Boiling the solution is just to settle the precipitate of gold. He later adds HCL acid to further clean the precipitation of sulfur by boiling though and that might confuse folks since most do not due to the trival gold ion exchange with hot HCL acid. As it all goes into the waste jar, trivial becomes moot, and is recovered. I think more folks should do this. The heat of melting gold breaks the molecular bonds within the HCL acid and does not affect the resulting pour in any fashion.
You are welcome. Nice touch boiling the precipitate to speed up the settling process. A good result from a quick cleaning of the piggy bank. Thank you Sir!👍👍🤟
Ha! I'm Learning! When the gold stuck, I thought too much flux! You told us that in prior videos also! Side note: crazy that borax can make gold stick to the mold but is meant to prevent it from sticking to the melt dish
Luckily, that mold was real hot so the borax stayed soft. If that mold had been any cooler then the borax would have glued the bar in and I’d probably have to break the mold just to get the gold out of it.
These waste container videos are some of my favorites. Something about making gold from garbage is like magic. Last time I asked about the waste treatment cleanup, you said it was going to happen in the Spring. Any plans for that? I know it's a huge project that is pure torture for you, but it's the most incredible process to watch.
I'm always amazed at how quickly you grab the gold bar from the water, that's less than a minute after being heated to over 1000 degrees celcius, does pure gold really cool off that quickly and release all it's temperature to the water?
Silver, copper and gold all have very high thermal conductivity, water has very high latent heat of vaporisation and specific heat capacity as well. The water boiling cools the surface very quickly to 100 degrees C (you can sometimes hear the squeak for a second or so as the inside temperature follows, to drop the next 60 degrees C is not much slower if the water is at room temperature.
The only thing that leads a rougher life than the 5 gallon buckets in Sreetips garage is the striped long sleeve shirt. R.I.P aqua striped shirt. 😊 Great video!
What's in the blue-grey liquid you've removed from the video PGMs? Didn't see the sulphuric acid to precipitate any lead this time can make sticky gold.❤
Stil mr Sreetips is an awesome goldbar. .i always watch your proces how you do this gold precipritations .keep it up mr Sreetips 👍greetings from the Netherlands mr Sreetips 🎉
My eyes are in awe 👀 And I got excited for my .25gram clean out from waste and filters! 😆 🤣 But a real lesson for all, process your filters guys, and check the stock pots, it does pay!
Y'know, I just ain't got a choice - I *HAVE* to ask - That tool you're using to block the ice cubes at roughly 7:50 - is that some sort of highly specialized, high-tech, acid-resistant tool from some chemical supply warehouse with a price tag in the $85.00-$110.00 range, or am I looking at your basic "repurposed 7-Eleven Slurpee straw"? :)
@@CothranMike I thought the same - Sometimes, he does stuff with 'em that make 'em look stiff enough to chip rocks, but other times, we get an edge-on view of the "splayed out" end that makes it look (at least to me) exactly like a Slurpee straw you can find in any 7-Eleven, and as most are aware, those are typically barely stiff enough to hold a good scoop of the Slurpee without collapsing.
@@sreetips Got it... The business end sure does look like one of those. I don't trecall ever catching an angle showing the "handle" end, which adds to the confusion - Can't tell it it's hollow or solid.
I’ve watched other gold refineries and refiners on TH-cam and you Mr. Sreetips. Your gold is the finest in the land. I’m sure other people do as good of a job as you, but not better.
I'm curious if you would be interested in doing a new video of recovery+refining without nitric (OTC chemicals only) I know you have a video of this already but that was about 5 years ago now. Very curious to see how you would go about getting that process done without the use of Nitric. Thanks again for all your hard work and amazing videos! Best regards.
Hey sreetips... I didn't see it happen today, but I've noticed In several vids that you lose some of the gold or silver out of the melt dish before it gets a chance to melt. Do you ever sweep up and recover your melt area? It might not be a bad idea to do once a year or so
Kevin my friend that bar was absolutely beautiful…… stupid/quick question… would you ever consider a collaboration video?? Prospector and refiner video sounds awesome 😊
It seems like you missed a couple of steps compared to your usual process? No sulphuric acid to precipitate any lead (but maybe you already knew there wasn't any?) and no stannous chloride test after the precipitation to confirm that there was no gold left in solution.
Be careful, the book is a little dated. She says in the book that you can do the reactions in your house with a fan in the window which is incorrect. The deadly gases will build up in the house. Must be done in a fume hood. Or that you should “protect the pipes by flushing with plenty of water.”
The recovery of gold stannate from copper chloride leaches that had tin still present is still an issue. Gold stannate will be in suspension, not solution, so it will not cement out, or drop.
@sreetips I have my doubts about how feasible that is when there is also gallons of copper chloride wastes to also evaporate and incinerate or pyrolyze. There's also the issue that gold stannate, aka Purple of Cassius, is a known high temperature pigment. I know that you can dissolve the dry residue in a molten sodium salt (sodium nitrate or possibly SMB) and form sodium stannate instead. Which is water soluble and can be washed out. I also read in a pigment forum that the addition of sodium chloride salt will cause the pigment to settle out of suspension, allowing easier collection, but I haven't tried that yet.
@CothranMike No. Copperas will drop gold in solution. Gold stannate is in suspension, not solution. Gold stannate is the purple positive stannous test result. It stole the gold from the gold chloride solution and is now a colloidal suspension. Tin in a chloride solution is stannous chloride, same as what one would test for gold in solution with. It can form if there was Tin on or in the materials being processed in a chloride leach.
My slimes from copper metal in e-waste are rarely black/grey and mostly tan/white. I figure I am cementing a degree of "tin/nickel/etc" along with the PMs, and losing a degree to the stronger tin ionic bonds still in suspension. These wastes are mainly from initial hcl boils, and I haven't yet seen sreetips reuse his copper2chloride wastes, but have seen dirtier scrapper types do this, seems the solution can handle a lot before fully pregnant with assorted metallic salts. Thanks to the comments I am reaffirmed that most of our slimes are not as pure to begin with, and need a lot more sorting out.
When is the next filter paper / stock pot or jewelers carpet or scraps refine ?!?! I love watching the tricky refines when the mad scientist comes out ! Love your channel long time sub keep up the awesome work!
It might be an interesting experiment to Date your waste containers between the time you do this and the next time. So Say this Set of waste is June 9th (or whatever date you actually did this) and later. Then, keep track of all the Gold "missing" from each of your estimates in your gold refining between now and the next time you recover your gold wastes. Then add that back to see what percentage it covers your "missing" gold from your estimates. Not really needed, but might be fun info.
Do you have a specific nitric acid that you use? I ask because it is a controlled substance, and the one's I'm seeing are high percentage. I think I remember you using something in the 30 percent category. Do you still have to be registered for it? Where does one register? I might be getting into this much quicker than anticipated, so I'm trying to figure out what I need to do to get the proper chemicals.
@@sreetips Do I need to register for it? And it's the muriatic acid that's in the 30's then, right? I don't want to muck up by grabbing the wrong caliber of these things. Also, though this is a question about gold and not silver; I've seen you do precipitation with multiple different compounds, yet you stick with the SMB. Is that just the most cost effective?
What's causing your flask and gallon+ jug to be tinted yellow even after rinsed? is there gold that's become embedded in the glass, or is that a stain from the nitric acid fumes or something?
MR. SREETIPS I HAVE A QUESTION Probably a dumb question, I am very uneducated in these experiments.😮 If you were to do the electrolysis with both gold and silver in solution and used both gold and silver anodes at the same time would the crystals that form be mixed or separate.....maybe a good idea for a video??¿¿
Oh ok....makes sense...thank you for the answer... I never thought I'd be so interested in chemistry type things but I've been watching your videos nonstop for the past week... learning a lot!!!
Better wet gold power pouring technique eliminates the 'milkshake effect', spilling it all over the table. Ever pour the other half of your milkshake from the metal mixing cup into the glass, and have the whole lump come out and sit on top of your glass just long enough to think "Ohhh Shiiii...." and then it makes a mess? Just me?
I want to get a fume hut I really enjoy your channel be watching a long time but I live in apartment when fumes go up and threw vent how long fumes last have to put threw window I have neighbors above and below me want it to be safe for them thank u
I’m fairly certain that platinum can be electrolytically refined. I’ve never tried it. Platinum is a different animal. Gold and silver are like a cookie recipe compared to platinum group metals.
When you poured rinse out at around 11:30 on video, it looked layered. Clear on top of yellow liquid. What were the 2 liquids, and why did they separate?
@@russ9740 I see what you are saying, this is after he rinsed the side of container from the smb drop and after the settling boil. The bottom layer looks golden yellow and the top looks clear, right? I'll look and see. Edited I look again and see this is after the addition of HCL and boil so what you are seeing is a small amount of dissolution of gold by the boiling HCL which is denser than the remaining HCL due to the gold ions it contains. He does this to clean the smb dropped gold by hot non-dilute HCL. That salute contains a very small amount of gold (trivial) but mostly it is full of ionic sulfur and its oxides left from the smb to drop gold via ion exchange. If it was ferris sulfide used instead of smb there would be iron sulfide to remove, these look even more like gold but are not. The yellow color in this instance is still sulfides though which look yellow and are not gold. I hope this helps you to understand the chemistry.
Hello Sritips can you make a video about recovery gold using concentration solution of sodium hydroxide then revining it normaly using aqua regia, because it would cool. The gold is from gold plated jewelry or the electronic contain gold.
What purity would this gold have, considering its from waste materials? Can you get 999 pure from just a single refining, because it was FROM a 999 pure refining?
Agree. The gold sponge/powder has way more volume than the melted gold. I actually thought it was going to be a full ounce as judged by the volume of the powder in the melt dish.
In my experience, the gold comes down as a very fine powder when I precipitate a tiny amount of gold from a large volume of solution: a half gram of gold dropped from a liter of solution as an example.
2 quick questions; if I'm doing 215 grams of gold filled scrap, how many milliters of nitric acid should I use so that when the process is complete the nitric will be safe enough to pour into a container to store in my car until I can build a silver cell? 2, how fn dumb am I for trying this? And 3, how about stuff that is slightly magnetic? Don't even think of putting it in there? Just the way they package that stuff is scary.
@sreetips Just over 200 grams? Big wide open area. Wait for a steady, yet not violent wind in my favor. 215 grams of material that has been 100% demagnetized and thoroughly cleaned & heated to get rid of all combustibles. Place it in my large ice tea pitcher that came with a glass stir stick. Pour out what nitric I need into a smaller beaker. Dress properly, cover all and wear respirator, googles, and long dish washing gloves over long sleeves. As soon as I pour it in get way the hell back and stay way the hell back for about 10-12 hours. Then go stir it and give it another hour or two. Not breath at all while I'm any where near it. Thought I had a jeweler to take my leftover nitric, but may have to set up a donation to the university instead. I surely want to have all these details worked out prior to attempting to do anything. And I just spent $50 on nitric acid, so I have to do something with it. Don't really want to be driving around, especially in summer toting 2 pints of 70% nitric acid. I wish I had some other options.
I ignored the warnings and did acid digestions in my back yard for a year before getting a fume hood. I now suffer reduced lung function and blurry vision from the nitric fumes. Even if you approach from upwind, the air currents will wrap around your body and pull the concentrated red nitrogen dioxide fumes right in your face. The fumes get in your hair, skin, clothes and eyes and in your lungs. Even if you hold your breath, turn and walk ten paces, you’ll still get the fumes in your lungs. Nitrogen dioxide forms nitric acid when it comes in contact with moist human tissues. Repeated exposure will even dissolve tooth enamel. I can’t emphasize it strongly enough. Don’t do this without a fume hood. Too dangerous.
No stannous test after adding the SMB? I know the waste is just recycled again and never lost but I was surprised to see you didn't test the waste solution after precipitation
Would be awesome if you could make one episode where you calculate all your products used and eventual losses. Like how much does it cost to refine one ounce of gold to .999
Some gold atoms: From refining wastes thou shall return to refining wastes A tiny amount of them course, but still funny to think that some gold might never make it into a bar

Boss, there is one question I have which I may not have seen you answer. How do you clean your glass? From used, to "ready for another batch"?
I scrub with alconox (a soap formulated for lab glassware) rinse with tap water, rinse with distilled water, then air dry on my dishwasher rack.
Bon Ami works great as well.
Thank you for another start-to-finish video. It is appreciated, sir!
I love your gold videos! It seems like you’ve got a ton of silver waste from the refining. I’d love to see a big silver recovery series.

Sreetips! I seen a video of someone making a mirror by pouring silver nitrate over a sheet of glass, can you do this with gold maybe????
I don’t know how to make gold nitrate.
work of art...

I remember in Hokes book she says to incinerate to convert the stannous to an oxide that’s not soluble, easy to filter it out.

I want to get a fume hut I really enjoy your channel be watching a long time but I live in apartment when fumes go up and threw vent how long fumes last have to put threw window I have neighbors above and below me want it to be safe for them thank u
Forget it, too dangerous.
Thanks luv watching your work
Is the color balance off? That gold powder looked black.
I didn’t adjust the color.
Question: Can you use an electro cemical cell to refine platinum?
I’m fairly certain that platinum can be electrolytically refined. I’ve never tried it. Platinum is a different animal. Gold and silver are like a cookie recipe compared to platinum group metals.
When you poured rinse out at around 11:30 on video, it looked layered. Clear on top of yellow liquid. What were the 2 liquids, and why did they separate?
I didnt notice any layering
Maybe it's just the angle. It was the pour ar 11:15 . Looked like it was clear on top, and yellow on bottom as you poured.
@@russ9740 I see what you are saying, this is after he rinsed the side of container from the smb drop and after the settling boil. The bottom layer looks golden yellow and the top looks clear, right? I'll look and see.
Edited I look again and see this is after the addition of HCL and boil so what you are seeing is a small amount of dissolution of gold by the boiling HCL which is denser than the remaining HCL due to the gold ions it contains. He does this to clean the smb dropped gold by hot non-dilute HCL. That salute contains a very small amount of gold (trivial) but mostly it is full of ionic sulfur and its oxides left from the smb to drop gold via ion exchange.
If it was ferris sulfide used instead of smb there would be iron sulfide to remove, these look even more like gold but are not. The yellow color in this instance is still sulfides though which look yellow and are not gold. I hope this helps you to understand the chemistry.
Hello Sritips can you make a video about recovery gold using concentration solution of sodium hydroxide then revining it normaly using aqua regia, because it would cool. The gold is from gold plated jewelry or the electronic contain gold.
I didn’t know that gold can be recovered with sodium hydroxide. I don’t know how to do it.
Amazing result ✌️
هل رسبت محلول بقطعة نحاس؟
No, I add copper to drop and traces of precious metals in the gold refining waste solution.
Have you thought about making your own Gems too? I've seen Rubies made in a Microwave. You'd be a true 21st Century Alacmist Jeweler.
I’m a refiner. I don’t know anything making gems.
What purity would this gold have, considering its from waste materials? Can you get 999 pure from just a single refining, because it was FROM a 999 pure refining?
It’s very close to three nines. Much can be determined about purity by the way the gold looks after it’s poured into a bar.
I have to do this project soon too.
Can't wait for a stock pot refining and then platinum and palladium refining
How do you deal with waste solution that has no precious metals in it? I can’t imagine you just pour it down the drain.
Waste treatment.
When I saw “pure gold from my waste” I thought he’d finally cracked it
Can you use h202 to dissolve silver for silver cell
No
$1000ºº from waste, not a bad days haul.
The final gold bar seemed to be a 1/20th of the volume of the wet gold crumbs filled in the crucible minutes before.
Agree. The gold sponge/powder has way more volume than the melted gold. I actually thought it was going to be a full ounce as judged by the volume of the powder in the melt dish.
sweep that floor I bet there's a nice little heavy loaf there as well . . go grab that jewelers carpet and drawer liners sweep it up . . .
Good job 👍🏻
Best supplier for chemist glass?
I bought all my glassware on eBay.
What happens to the silver that accidentally gets in your gold stock pot?
It turns to silver chloride
Thank God bless you❤
Puedes precipitar rodio y iridio?
I don’t have any experience with rhodium and iridium.
@@sreetips mmm Cres poder investigar y hacer alguno de esos en un futuro sería muy interesante
Beautiful.
I liked the part when you said how toxic your waist treatment bucket is !!! People take it for granted sometimes
Turning waste into gold is always entertaining!
Hey streetips I really want to start doing this can you help me know everything i would need to start
I don’t provide any training or tutoring because this is my hobby. But I’ll try to answer any questions posted in the comments section.
Why is my gold drop getting so fine of particles. My last one I did was hard to stop it trying to float
Quintion3997 tell us more about your drop - this is after you add the smb, right? What colors do you see?
@@CothranMike same as usual yellow green because of contamination of copper and green mask on electronics
@@CothranMike it may have something to do with me at the bottom of my SMB maybe a little more fine
In my experience, the gold comes down as a very fine powder when I precipitate a tiny amount of gold from a large volume of solution: a half gram of gold dropped from a liter of solution as an example.
2 quick questions; if I'm doing 215 grams of gold filled scrap, how many milliters of nitric acid should I use so that when the process is complete the nitric will be safe enough to pour into a container to store in my car until I can build a silver cell?
2, how fn dumb am I for trying this?
And 3, how about stuff that is slightly magnetic? Don't even think of putting it in there?
Just the way they package that stuff is scary.
You should wait until you can do it in a fume hood. No way to safely do these reactions without a fume hood.
@sreetips
Just over 200 grams?
Big wide open area. Wait for a steady, yet not violent wind in my favor. 215 grams of material that has been 100% demagnetized and thoroughly cleaned & heated to get rid of all combustibles. Place it in my large ice tea pitcher that came with a glass stir stick. Pour out what nitric I need into a smaller beaker. Dress properly, cover all and wear respirator, googles, and long dish washing gloves over long sleeves. As soon as I pour it in get way the hell back and stay way the hell back for about 10-12 hours. Then go stir it and give it another hour or two. Not breath at all while I'm any where near it.
Thought I had a jeweler to take my leftover nitric, but may have to set up a donation to the university instead. I surely want to have all these details worked out prior to attempting to do anything.
And I just spent $50 on nitric acid, so I have to do something with it. Don't really want to be driving around, especially in summer toting 2 pints of 70% nitric acid. I wish I had some other options.
@sreetips ...they're back to stealing my food stamps again.
I ignored the warnings and did acid digestions in my back yard for a year before getting a fume hood. I now suffer reduced lung function and blurry vision from the nitric fumes. Even if you approach from upwind, the air currents will wrap around your body and pull the concentrated red nitrogen dioxide fumes right in your face. The fumes get in your hair, skin, clothes and eyes and in your lungs. Even if you hold your breath, turn and walk ten paces, you’ll still get the fumes in your lungs. Nitrogen dioxide forms nitric acid when it comes in contact with moist human tissues. Repeated exposure will even dissolve tooth enamel. I can’t emphasize it strongly enough. Don’t do this without a fume hood. Too dangerous.
@@sreetips 10-04
No stannous test after adding the SMB? I know the waste is just recycled again and never lost but I was surprised to see you didn't test the waste solution after precipitation
I could tell based on my experience that all the gold had dropped.
Would be awesome if you could make one episode where you calculate all your products used and eventual losses. Like how much does it cost to refine one ounce of gold to .999
I can tell you that this one cost less than fifty dollars all in. Not counting the metal.
Some gold atoms: From refining wastes thou shall return to refining wastes
A tiny amount of them course, but still funny to think that some gold might never make it into a bar
I suppose I could pour the final waste solution (when I retire) through a filter paper
@@sreetips do you have a retirement plan in sight soon or you plan to keep going for a while?
I’ll retire when I can’t get up and get to it. In other words, I’ll probably never retire.
@@sreetips That's when you know someone has a passion and not a job. When work is fun and not a chore. Glad to hear it. :)
Hey, know what would be cool? Get melt molds in different shapes. Make a heart of gold. Ha
Le freak, ce chic,
Stump out!
