Kevin, I have been enjoying your videos for quite some time. You helped me bridge gaps when I was first learning about refining. I have always appreciated and recommended your work, as an example and as a teaching tool. I can firmly say that I enjoyed it much more when you wore your Navy ball caps and talked to us face to face. Bring it back brother.
No need to apologize. Even if you don’t speak in the video, I still love watching it. Thank you for your selfless and free provision of refined knowledge.
Wow that oxalic acid precipitation was stunning (nerve wracking too). That dry gold sponge melt was brilliant and such a beautiful gold bar at the end. 👍🏻❤️
I appreciate how you begin each post with a safety message, and you continue to demonstrate how important safety is throughout. This was a good demonstration of why you are so cautious.
This was edge of the seat for me, and seeing you put the pre heat torch on the big cavity on the mold made it even better. Bravo Zulu Senior Chief! It sucks that I can only give a thumbs up once for the video. I'd give more if I could.👍
That was excellent, I love the way the dry gold melts as well. The reaction when you combined the two had me on the edge of my seat as well, thanks for taking the risks and letting us see it. Fantastic video as usual Sir!
That "Alien" looked angry forming while falling out of solution! Also i mist say it seemed to have more of a "sponge" appearance than the powder from using SMB. Nice contrast between the two. And once again the pour shot was superb!
Smb precipitation is cool looking and some of your recent ones have been particularly pretty but I've always loved the oxalic acid reactions. Especially the precipitate. Just so weird and almost organic 👍
Always fun to watch. Also, how much weight was left as a drop on the spout of the melt dish? Looked like there was a decent sized bead that hung and cooled there. (Or are my eyes playing tricks?)
The techniques you used in this video to refine your karat scrap is identical to how I always double refine my karat scrap which results in a sparkling flawless gold bar. Fun stuff Sreetips.
Your video's never cease to amaze. Seeing the pure gold suspended in such a clear liquid form from the aqua regia is so beautiful! What a cool process.
I have been watching how you refine the gold using SMB and I have to say that the refining with the Oxyolic acid looks cleaner and also heating up the gold to dry it off before going to the melt dish works way better! As for the finish product, the bar looks way better and very beautiful Sreetips! I gotta try this method out one day! Great vid as always! 🍻🤙🏽🥇
Thats the most beautiful bit of gold . Sreetips, This was the most fun I've had sitting in my sofa. I really enjoyed the precipitation process.Tho I kno it was very nerve racking.. I sat mesmerized as you poured the gold into the oxalic acid...an it fixzled to life reacting hurriedly as gold fell into a beautiful carpet of gold. Then with each successive pour the gold grew an grew.From a carpet to an Alien face.Then to what looked like a whole creature.... Then you clean an prepare the beautifully precipitated Gold!! It looks clean an just beautiful...Im beyond excited...Then you carefully dry an prepare to melt the Gold. Then you pull out the Big Dish a new glazed beauty!! I kno this is gonna be special..Then the fire pops to life ...an its on!!! The Melt is on ...The beautiful end to an amazing to this point transformation!! Then the beautifully dry powder of gold is heating an melting an you can already see how pure this Gold is....Then you pour the Gold into the ingot an the shine of the gold whilst being poured...well Sreetips it's perfection ,sheer thing if beauty!!
Good vid yet again! Oxalic acid gives good results but as you say, nerve racking. I am now using ferrous sulphate (home made) almost exclusively. Easy to make and much better purity results than SMB.
Yes, ferrous sulfate is known for: bring down the gold, all the gold, and nothing but the gold. I remember a guy on the forum who said he kept a glass coffee pot full of sulfuric acid and iron to make ferrous sulfate. It does produce high purity gold.
I gotta say like you I like the way the gold melts when you dry it. As far as the drop goes I like the SMB better yes the other one is cleaner but the SMB is more dramatic excellent video thank you for sharing this with us six stars sir
I know that precipitating gold with oxalic acid or copperas are kind of a bit inconvenient when compared to options like SMB but I have to admit that these are 2 of my favourites to watch.
I love your videos! They are truly informative. I have one frustration with your TH-cam channel. It is extremely hard to navigate your videos. If you could sort your videos is to play lists it would be great. For example a list for stockpot videos, one for silver cell videos, one for PGM, And so on. Again I love your videos and this one adjustment would make your channel more enjoyable and easier to individual video series. Thank you!
SREETIPS you seemed a little upset hope your doing ok I love watching you and learning the correct way and safe ways of your hobby refining it absolutely mesmerizing
@@sreetipseven though you are repeating yourself keep in mind there are most likely new folks just finding you and I am sure they would love to hear what you are doing. Then there are the people like myself who just love to hear you talk!
That formula of double refined with oxalic acid produces a truly breathtaking bar of gold ...and I see someone has been working on their pour technique 😊 68.8g bar should fetch a premium looking that pure...I'm sure once u stamp it with the sreetips brand u might even be able to get more than spot
It amazes me how you and Mrs. Sreetips are able to find so much gold and silver. I would love to do this as a hobby, but living in the middle of the desert and hours from civilization makes this hobby impossible for me. Thanks for making these videos as I get to live vicariously through you watching them!
No, just an avid yard sales. She loves the hunt, but hates refining. I love refining the metal, but I hate going to sales. We are the perfect compliment.
I’m a long time fan…I love your channel! I wish you could, maybe tryn make your own nitric acid… it’s probably easier to buy, but you’re experience, the content, would be almost the finding the missing element of refining. Shipmate. Mad respect, sir.
Nice work again, thanks for the time and effort for making this video, and thank Mrs. Sreetips for finding all the material you use, she has a good eye.
I love the intermediate stage between the gold sponge and the fully melted gold. It's almost like art. Maybe someday you could do a refining video and make that the intermediate stage the final product!
Wow that is a beautiful bar! I solved the mystery of the gold drop from your burnt gold chloride video.. in this video there is a little drop stuck underneath the lip of the spout after the pour... you must have also done that on a previous pour before melting the recovered burnt gold chloride (not sure if this was already mentioned or not).
Am I the only person who noticed the drop of gold left on the lip of the melt dish after the pour? Love watching your various techniques thank you for another awesome video.
It's an amazingly pure gold bar. I wonder if you could use an XRF device to measure the purity of each bar you produce. It would give a significant quantitative idea of the gold's purity.
I’m a retired Naval Engineer (Main Propulsion). My degree is from Embry Riddle Aeronautical University. I flew small airplanes at the corporate level, but it nearly ruined my marriage so I quit. I became interested in refining because my wife buys scrap gold at local sales. I learned on the goldrefiningforum.com
@@sreetips that's quite a career. I have been collecting gold bearing parts for about a year now because I eventually want to try extracting and refining it. Thanks for the website. Hopefully, when I actually do it, I don't ruin it haha.
The inquarting (I know I butchered the spelling) process, especially the part when it's poured into the water, is one of my favorite things to see. Cheers from Texas
What I like to see is the two different acids mixing. They have different specific gravities that you can see in the clear solution as a shimmering. What I hate to see is the gold solids going into the waste container.
the "waste container" also goes through aa recovery process to get all the gold that settles out in it and that may be in solution too, but i do not think i have seen a video of that process yet
much prettier as the sponge than it is as a bar id love to see what it looked like half melted so it pooled and held as one lump but still had some of that sponge texture to things
Am fascinated by the whole process of refining that you go through. Very many thanks for taking the time and putting in the effort that you do for these videos. Few quick questions.... 1. Where do the fumes from you extractor go? 2. Do you have to put up signage at your residence so in the unfortunate case that emergency services have to attend, they are aware of the hazards? 3. For melting, have you considered using an induction smelter? Removes the whole issue of naked flames and explosive gases, plus no chnace of introduction of carbon into the melts too
First off, I as much as all off the fans here loved this video! It was another very nice example off all the steps needed for a good end result. But Man!! I cracked a laugh 28:22 minutes! Maybe something for a novelty t-shirt 😂 “This looks like an alien space creature in my beaker… Sreetips 2023”
Leading up to the 9:30 mark, where you cooked the aqua regia down to a syrup --> it looked like there were some drops of chloroauric acid condensing on the beaker lid??? Were you losing gold as it steamed away?? (I'm not at the end yet so I haven't seen your calculations you always share)
great video as usual, thank you!! I have always wondered if it would make a difference in the dilute nitric boil if instead of using poured shot, you put the inquarted gold through a roller, to turn it into a thin sheet, would the thickness of the material reduce the amount of time required on the boil? and would the added process and time to roll it out be justified.
you are a man of great talent . If I turned a corning ware dish upside down and set a beaker of gold on top of it . I am certain it would wind up on the floor
did anyone spot the drop of gold that hold on to the lip when sreetips pouring 36:14 not sure if that 68.8g but was it 68.9g? love the videos buddy just try point it out
@@sreetips thanks for the answer. Just thought I'd ask. I have been enjoying your videos. The chemistry involved is absolutely crazy. I hadn't known just what's involved for refining gold. It's been an educational experience
Could you use a melt dish for drying the gold on the heat plate? I wonder about losing a few crumbs when transferring from the current heating pan to the dish.
Brother never use untreated fire blanket indoors. Rigerizer stops the carcinogenic particles of the fire blanket becoming airborne. Fire bricks are the best option in an enclosed space. Awesome episode brother regards from England.
The gold looked so good in the melt dish just Pryor to pouring there was no need to use a flux as the refining had removed 100% of the contamination ..👍
@sreetips understandable. No worries. I guess we all kinda know those parts by heart now. What made you decide to use oxalic acid this time? Are you trying out different techniques for between refining/yield? Did you run out of sodium metabisulfite?
I used to have my waste treatment bucket base of my fume hood. It gave off ammonia. There was a film of ammonium chloride on everything in my shop. I moved them outside. I’ve excluded ammonia from all my processes. Except oxalic acid because that’s what the book calls for.
@@sreetips (chuckle). You were using a lot of ammonia for that to happen! Still. Using saturated NH4Cl solutions to precipitate the Pt, during your Pt recovery efforts, could have done all that. Not recommending you use it for anything else. Heck. Just take any one of your household cleaning products with ammonia in it and just blow it across the top of your beaker. If you see the cloud of NH4Cl, you can stop the boil and move on. It’d be adding a whimsically small amount of NH4Cl to the process.
I noticed that during the pour at the end it seemed like a tiny amount of molten gold remained on the lip of the crucible and wondered if this was added to the ingot to round it up to a simpler number ( trying to avoid writing a spoiler by mentioning exact weights)
There are many mysteries in life that science can answer but one and that is, why doesn't Sreetips have over 1 million subscribers yet? So if you haven't hit that subscribe button yet please do. Sreetips has so many videos on precious metals done through chemistry and he uploads several more a week, you might just learn something.
Thank you. I must remember to start announcing for folks to hit the like and subscribe at the end of the video. Do a little self promotion. But frankly, I never dreamed that a quarter million would be interested in refining gold. I thought it was too narrow of a subject. I’m thankful for what I’ve been granted!
@@sreetipsthe fact that you did not ask for likes and subs is exactly why I did it. There is another youtuber that I follow who always says that if you are new he hopes to earn your subscription. Nice touch saying it that way.
Ok, thanks for the feedback. I’d rather let the content speak for itself anyway. If they like it then they’ll hit hit those buttons on their own volition.
instead of pouring the waste off into a separate beaker could yo not pour it into your filter setup and then just add the filter to your pile thereof? Also, after dissolving the gold in aqua regia would the gold in solution start to eventually form gold crystals and come out of solution?
Yes, but I like putting it in my savings account (waste container). I’ll make a withdrawal soon in a future video. If I evaporate it down to dryness, the gold will form solid orange chunks of chloroauric acid crystals. They are a salt of gold (gold chloride) and can be stored indefinitely. And won’t be detected by a metal detector. To reconstitute, dissolve the gold chloride crystals in a little hot aqua regia, filter out any junk. Precipitate with SMB and “bobs your brothers uncle” you’ve got your pure gold back!
Ohhh, Ahhh!!!, beautiful from beginning to end, question Sreetips, are my eyes deceiving me or does the solution turn from reddish to orangish as it cools or perhaps I'm not observing some dilution (it does seem to go from orangish to yellowish as the ice cubes melt) ?
Kevin,
I have been enjoying your videos for quite some time. You helped me bridge gaps when I was first learning about refining. I have always appreciated and recommended your work, as an example and as a teaching tool. I can firmly say that I enjoyed it much more when you wore your Navy ball caps and talked to us face to face. Bring it back brother.
Would love to see an April fools video of you making a loaf of bread or baking something.. for Mrs Steetips of corse
Yes but it’s narrated just like a gold video…”and this is called inquartation…incremental dosing nitric acid…SMB…”
Yeah, or a video, of how to make gold out of led.....
Take a loaf of bread, and refine it back to flour, butter, yeast, and milk …I know he can do it
He can make a gold loaf for her 😂
No need to apologize. Even if you don’t speak in the video, I still love watching it. Thank you for your selfless and free provision of refined knowledge.
Oxalic precipitation is my favorite then SO2 gas ! The bars look so amazing! Keep up the great work!

If it was gold stuck there, wonder how much closer the result was to 70g once you add it in. Curious to know. =)
I’ll check

Got to imagine the makers of stump out his brand of smb has a bunch of impurities in it. They won't care too much about purity.
@@OneOfDiseaseIt’s just a branded version of industrial sodium metabisulfite. It better be pure from the chemical plant.

You are not. Alone
First one I’ve watched with you using oxalic acid. Was a little nervy when it started to bubble up the beaker. Great stuff as always 👍
Fascinating video .... Excellent experiment .... Thank you Sreetips 👍👍
I like how Sreetips has some left over SBM (probably) in his waste container that precipitates the gold in the solution he pours off into it.
That thing is full of SMB and SO2 gas. I have to open the stopper with it in my fume hood so it doesn’t gag me.
It's an amazingly pure gold bar. I wonder if you could use an XRF device to measure the purity of each bar you produce. It would give a significant quantitative idea of the gold's purity.
I don’t have an xrf. But the big refiner I used to sell my gold to, did. They shot it to determine my pay out. Came back three nines, every time.
That dried up nicely!
So fluffy

Few quick questions....

3. For melting, have you considered using an induction smelter? Removes the whole issue of naked flames and explosive gases, plus no chnace of introduction of carbon into the melts too

There’s losses al along the way. But if it condensed in the beaker, then I got it back. It’s the droplets that fly out of the beaker that get away.
Great video!!! It would be nice if you put the chemical reaction in screen, in order to understand more what is happening.
I don’t know how to figure it. I’m not a chemist. I guess I could ask a chemist. It should be the same reaction every time I do it.
Was that flux or a small bead that stuck to the outside of the melt dish spout when you did the pour?
I didn’t notice. I’ll give it a look.
It looked like gold.
Verified, it’s a dot of gold.
Nice to see the differance in clarity
great video as usual, thank you!! I have always wondered if it would make a difference in the dilute nitric boil if instead of using poured shot, you put the inquarted gold through a roller, to turn it into a thin sheet, would the thickness of the material reduce the amount of time required on the boil? and would the added process and time to roll it out be justified.
Yes, and yes. I’d rather let the chemicals do all that work.
For us that follow you, no explanation required 😊
you are a man of great talent . If I turned a corning ware dish upside down and set a beaker of gold on top of it . I am certain it would wind up on the floor
Hi Sreetips, I enjoy your videos.
Quick question. Can I use de-ionised water instead of distilled water in my experiments?
I would not recommend it, deionized water usually contains some organic chemicals.
I think do, but I’ve never tried it.
The best so far !
awesome a new sreetips master class 🔥
did anyone spot the drop of gold that hold on to the lip when sreetips pouring 36:14 not sure if that 68.8g but was it 68.9g? love the videos buddy just try point it out
I just found you thanks to TH-cam. What you're doing is absolutely amazing.
Have you ever done gold ore?
No experience with gold ore. Mostly karat scrap gold.

The sponge takes up more volume when using the oxalic precipitation but melts much faster, too.
I noticed that.
All that powder.. it never fails to amaze how it melts to such a smaller amount.
Could you use a melt dish for drying the gold on the heat plate? I wonder about losing a few crumbs when transferring from the current heating pan to the dish.

@@sreetips for sure! Well thanks for your content! I look forward to every episode! 👍👍👍
Those fumes are HCl gas made somewhat visible by moisture.
If you blew ammonia across the top of the beaker, you’d get a highly visible NH4Cl cloud.
I know. It’s another reason I hate working with ammonia.
@@sreetips it’d just be a spot test. Like the SnCl2 test for remaining dissolved gold.
If you’re boiling off HCl, your NOx evolution is complete.
I used to have my waste treatment bucket base of my fume hood. It gave off ammonia. There was a film of ammonium chloride on everything in my shop. I moved them outside. I’ve excluded ammonia from all my processes. Except oxalic acid because that’s what the book calls for.
@@sreetips (chuckle). You were using a lot of ammonia for that to happen!
Still. Using saturated NH4Cl solutions to precipitate the Pt, during your Pt recovery efforts, could have done all that.
Not recommending you use it for anything else. Heck. Just take any one of your household cleaning products with ammonia in it and just blow it across the top of your beaker.
If you see the cloud of NH4Cl, you can stop the boil and move on.
It’d be adding a whimsically small amount of NH4Cl to the process.
347 👍's up sreetips thank you for sharing 😊
It looks like the sludge at the bottom of a lake in the fall when the lakes turn over it looks organic
Every second was worth it
I noticed that during the pour at the end it seemed like a tiny amount of molten gold remained on the lip of the crucible and wondered if this was added to the ingot to round it up to a simpler number ( trying to avoid writing a spoiler by mentioning exact weights)
There are many mysteries in life that science can answer but one and that is, why doesn't Sreetips have over 1 million subscribers yet? So if you haven't hit that subscribe button yet please do. Sreetips has so many videos on precious metals done through chemistry and he uploads several more a week, you might just learn something.
Thank you. I must remember to start announcing for folks to hit the like and subscribe at the end of the video. Do a little self promotion. But frankly, I never dreamed that a quarter million would be interested in refining gold. I thought it was too narrow of a subject. I’m thankful for what I’ve been granted!
@@sreetipsthe fact that you did not ask for likes and subs is exactly why I did it. There is another youtuber that I follow who always says that if you are new he hopes to earn your subscription. Nice touch saying it that way.
Ok, thanks for the feedback. I’d rather let the content speak for itself anyway. If they like it then they’ll hit hit those buttons on their own volition.
Never seen a man turn cooked ground beef into a gold bar until today…😂…keep up the great work
Great another video by my favourite TH-camr Kevin the gold king😂
I noticed a drop of gold was left on the underside of the lip of the crucible when pouring.
I like your style!!! A 5 liter beaker can come in handy ! Well done !
I like the watch in the background just spinning
Great video as always, but I think you missed a drop on the tip of the melting dish, probably the lost 0.2 grams 36:14
I’m staring at it right now!
Adding a little excitement to the refining ❤
There is a small drop of solid gold stuck on the outside lip of the melt dish after your pour
$4400 value there. Nice and shiny. I buy Oxalic Acid in 50lb bags. We use it for KMNO4 stain removal. 10 years Hon discharged E5 here :)
Thank you for your service.
instead of pouring the waste off into a separate beaker could yo not pour it into your filter setup and then just add the filter to your pile thereof?
Also, after dissolving the gold in aqua regia would the gold in solution start to eventually form gold crystals and come out of solution?
Yes, but I like putting it in my savings account (waste container). I’ll make a withdrawal soon in a future video. If I evaporate it down to dryness, the gold will form solid orange chunks of chloroauric acid crystals. They are a salt of gold (gold chloride) and can be stored indefinitely. And won’t be detected by a metal detector. To reconstitute, dissolve the gold chloride crystals in a little hot aqua regia, filter out any junk. Precipitate with SMB and “bobs your brothers uncle” you’ve got your pure gold back!
Awesome video, you left some gold on the outside of your melt dish. You can see it on the video at 36:14. That might have gotten you the 70g.
Ohhh, Ahhh!!!, beautiful from beginning to end, question Sreetips, are my eyes deceiving me or does the solution turn from reddish to orangish as it cools or perhaps I'm not observing some dilution (it does seem to go from orangish to yellowish as the ice cubes melt) ?
That’s correct. It turns more yellow as it cools.
That’s an amazing amount of raw material!
Is that one weekend’s amount of Mrs S ‘wheeling and dealing?
Yes
@@sreetips Holy Mackerel! It’d take me years to do that.
Come clean: you have a side business ‘buying gold at top dollar!’
Yes, I do. But Mrs sreetips finds most of the gold. I’m
Great job as always! When sourcing gold, do you ever aquire white gold?? Cool vid idea?
Yes, it has the same amount of gold in it as yellow gold.
