I was looking at that 33.3gr of scrap platinum jewelry and realized I was looking at $1000 right there the way is. But why sell it like that when you can _refine it?_ The mad chemist is off again and we are on another adventure. /me puts his seat belt on.
Good job. Looks like the condenser stage is struggling to keep up though, lower heat or invest in a better pump, also your pump is fighting a lot of gravity with the reservoir bucket on the floor which will impact it's efficiency. 🧐👍🙏
It's like those TH-cam videos of watching a fireplace 😂 And really dude you had to be continued this one like a Saturday morning cartoon.... Ahhhh ! LoL
I heard a rumor that human waste water treatment facilities have a portion of the process dedicated to separation of the heavy metals. Some of that is gold... But who knows , sounds like crap to me
Nitrogen Dioxide fumes (NO2) from the reaction dissolve in water to form HNO3 (Nitric Acid) and HNO2 (nitrous acid). HNO2 is very unstable at RTP so it disproportionates into NO (nitrogen monoxide) and NO2 (nitrogen dioxide) and H2O (water). The water stays in solution and the NO is oxidised by oxygen in the air to form more nitrogen dioxide. This NO2, along with the one originally produced in the disproportionation, can then react with more water to form HNO3 and HNO2, and the cycle with HNO2 repeats. However, the HNO3 produced herein is significantly dilute, as such it may not be cost-effective and/or profitable to purify/concentrate it, as the dilute nitric acid hereinbefore mentioned will not be useful to for the uses of the publisher of the above video.
What's the purpose of the condenser with cold water running through it for this reaction? First time I've seen you use that with aqua regia, is this special for platinum?
@@sreetipsplease give us a review, some time in the future, and explain how much acid you save with this reflux tube. Acid that is not going up and through your fume hood.
Thanks, I came to ask the same thing if no one else had. Does this save any metal? I remember once you put paper over the fumes of a reaction and said you were losing metal.
Again! Good content, but dangerous content! I remembered the first viral video's I watched on TH-cam: Will it Blend,.... where some guy in a white coat put an early iPhone (very expensive back then) in a premium blender,... just to make a case for the blender. When he opened the beaker, dark coloured dust-powder swirled up in the air: and then he said his magic words "don't breathe that"
I have never seen a master like you. Excellent work and no waste of acid or metal. I wish I had a master like you. With my respect and love, I wish you and your family a long and healthy life.❤❤❤❤
@@sreetips I don't know English well yet, so forgive me if there are any mistakes. What I'm curious about is why you add silver into it and melt it all while melting gold.😊
I might have said it earlier, but I can't remember, so I'll say it again ;-) Sand bath is not the "most bestest" choice, since sand is poor conductor of heat, and may scratch glassware. Brass or bronze shavings are much better, albeit in this particular case should the flask crack there would be "quite a lot of fumes and activity" going on. Quartz sand is best for heat conduction - can't say what kind of sand this one here is, but it may be some second grade (i.e. less pure) quartz sand, which won't make any difference in this application (It's kinda yellowish, while regular quartz sand is pure white/ slightly off-white, with a very slight greyish shade.)
get it hot enough and Pt will oxidize.... Also, Pt melts at 3125, map gas burns at 3700f, theres absolutely a way you can melt Pt using map, propane etc especially if u have a torch tip that force feeds air into the combustion chamber (like the 1 you are using...) personally i use the h2o2 test as Pt will catalyze the peroxide OR use Archimedes density test....
I could probably get the thin strips of Pt to start to melt if I held the map torch to it long enough. But what I’m looking for is any gold that may be present. Gold will begin to melt with map torch very quickly.
Obviously you know your own numbers but are PGMs really worth the effort, cost of the scrap, cost of reagents and waste disposal with their current prices? Genuinely interested how viable it is right now.
It’s too dangerous for the hobby refiner. But I figured it’s either this, or let the big refiner have it. At least I’ll get to extract some value via the videos. But after this, I’m done with platinum refining. And this time I really mean it.
Very interesting proces mr Sreetips...i watched it being curieus and i'am learning from this mr Sreetips thanks for the video very good by the way ..haha greetings from the Netherlands
thank you sreetips for showing the platinum refining process. i know its really not worth your time and resources to process. but its very interesting.
@sreetips good thing you put them in the vapour return delivery vessel. Do you still lose PGM's doing this sort of reaction through vapour loss? As I see, you have always done your best to capture as much as possible. I always wondered how much PGM's travel in the vapour. Obviously, it would be micro grammes, but it is still a loss.
Platinum and palladium I can get by with, albeit in a crude way. But the other four metals in the platinum group (rhodium, iridium, osmium and ruthenium) are a total enigma to me.
You're a brave man! At least it should be fairly easy to recover that metallic iridium from the bottom of the vessel once all the platinum gets complexed into the hexachloroplatinate ions. What will you do with that excess iridium - sell to your refiner? About $170 a gram at the moment which is still extremely cheap considering how incredibly rare it is and the BRICS nations control virtually all production - only about 6 tons a year globally.
Andy, I’ll collect it in a filter and hang on to it. The big refiners will give credit for Platinum and Palladium (they pay 80%). But none that I know of will give credit for Rhodium or Iridium. Osmium and Ruthenium - forget about it.
Sreetips, you do not sound thrilled about the prospects of refining platinum again lol. You got me into refining years and years ago and I still do it to this day. Seeing how much you hate refining PGMs is also the reason I'll never attempt it. Seems damn dangerous and a pain in the butt. XD
It totally is. But I had all this platinum that I accumulated. So I figured what the heck. I’ll be glad when I can get back to my gold and silver videos. They are like a cookie recipe compared to PGMs.
It's extremely underpriced at the moment and supply is dominated by BRICS countries. Incredibly useful metal as a catalyst but it's not really considered a monetary metal right now. It should be and probably will be soon.
You know what’s been worse? Cash. In 1930, a gram of gold was $1.50 Today a gram of gold is $85 So $1.50 divided by $85 equals 0.1764 And 0.1764 minus one equals 0.9823 So a dollar has lost 98.2% of its value since 1930. And it’s got a long way to go. So how much further down can it go? Oddly, even if it loses another 50% (gold at $170 per gram) that will only take it down from a 98.2% loss to a 98.7% loss. But on the other side of that, the cost of living will double (because the currency has lost half its value - due to currency creation out of thin air). And that’s what inflating the money supply does for you. It’s evil. I’m stacking gold, that’s rising. Not paper currency, that declining. De-dollarizing.
you must have some platinum salts and oxides in solution or in filter paper from the previous videos where you refined PGM? you got a palladium button out at the end but there must have been some platinum in the mix too?
I don’t think the jewelers buy it. None that I know will buy it. I agree with silver and gold going higher, much higher. Especially now that they must create more currency out of thin air to foster rate cuts. They’re doing evil.
It's definitely refluxing, you can see liquid dripping down from the condenser. Even if some nitrogen oxides are escaping, the reaction flask isn't drying out.
Hold up. Since when did they figure out how to alloy Titanium with platinum?? Last time I checked, the turbine blades in an LM 2500 were titanium alloy, not platinum. I still have a few pieces from the engine we burned up in the Gulf war...
It's Rhenium - th-cam.com/video/VRccwkEmOYg/w-d-xo.html (Periodic Table of Videos channel). Probably some confusiom with rhodium here (which is a PGM metal), since rhenium is also considered a "noble" (precious) metal.
Thank you my friend and I just think of the ancient people of Western kind with Alchemy and to me what you do is just very spiritual As We Know the blood of your ancient ancestors flows through your veins blessings to you and yours
Stuff got real. Sreetips took out his old bong for a reaction vessel because all his other glass ware was full of palladium salts.
Hahaha. Thought I could hear Jimi Hendrix in the background :)
How can I get me one of those..😂😂😂😂
I was just about to comment, bro did chemistry with a bong
Gotta do whatcha gotta do. ¯\_(ツ)_/¯
Don’t forget the joint grease

Good Morning.
I deeply respect his commitment to clear labeling, but never more than the Tupperware full of sand labeled SAND. That brought me joy.
Hey sreetips, have you ever extracted from ‘silvadium’ utensils or other items? Love watching you work, man!
No, I’ve never heard of it. I processed some “Staysilv” 15% silver solder one time.
Need to use that contraption more to save on nitric acid. Or use a bubbler and bubble the fumes thru water and make more nitric

i can not wait until you do a recovery and purify video on all the radium that you have added up over time
Awesome, this is how i do most of my digestion!!! You use every bit of your nitric acid !!! 😊
Oh boy! Now you're cooking. Nice change up from your usual refining so good luck on this one.
The reflux condenser is a great way to be more efficient. Especially if you have to go to higher temps for a reaction. ❤
I should probably use it for every digestion reaction.
Cost of reagents can have a fairly significant impact on the total cost of refining. Especially nitric acid.

Showing the cool glassware.
Couldn't tell if he was setting up a bong or processing platinum
Would dropping Pl in methonal be a reasonable way to determined genuine metal?
Bubbling would indicate a conversation to formaldehyde.
Not sure about that.
Yeah enjoyed the process last time, was different and different is good and no one can say isn't facinating.
There is so much to learn, and so much to know about chemistry!
Thanks for the vid... Just do not take a toke off that thang man.. Be the last worst buzz you would ever have.. :P
Great video can't wait to see other videos thanks for sharing sreetips

Would like to see your button collection sometime. Going to make some bars?
Love the science but Platinum just seems like more work the ROI
Would be cool to see how platinum is refined and then see it done into metal bar
I’ll be lucky to get it to melt into a blob.
I would be really impressed if you done an iridium refining process. 3g of IR Would be worth $1395
Platinum and palladium I can get by with, albeit in a crude way. But the other four metals in the platinum group (rhodium, iridium, osmium and ruthenium) are a total enigma to me.

Twist the pieces as you’re cutting them Sreetips. Save yourself some time.
Good advice. I remember reading that last time I did this.
Here we go again.
Getting fancy with all the glass what is the condenser for not really sure
Reflux
Holding platinum has been a bad investment.
It's extremely underpriced at the moment and supply is dominated by BRICS countries. Incredibly useful metal as a catalyst but it's not really considered a monetary metal right now. It should be and probably will be soon.
Not if you bought it at $60 an ounce like I wanted to do in the 70's, just out of high school!
You know what’s been worse? Cash.
In 1930, a gram of gold was $1.50
Today a gram of gold is $85
So $1.50 divided by $85 equals 0.1764

So a dollar has lost 98.2% of its value since 1930. And it’s got a long way to go. So how much further down can it go?
Oddly, even if it loses another 50% (gold at $170 per gram) that will only take it down from a 98.2% loss to a 98.7% loss.

Yes, but the flame test cinches it for me.
you must have some platinum salts and oxides in solution or in filter paper from the previous videos where you refined PGM? you got a palladium button out at the end but there must have been some platinum in the mix too?
Probably not worth the effort…
It will go in my stock pot and accumulate there.

The nitric acid fumes are escaping from your addition funnel, which bypasses the condenser. It's not actually refluxing, if that's what you want?
