I really enjoy your vids sir. I learn more from an hour with you than I did in months of high school. Your explanations are always thorough and clear. You are a hard working person and I appreciate every bit of content that you make for us.
I Whole-Heartly Agree. Definitely fun to watch and learn. Thank You Sir.
I have had success refining gold using inquarting gold with silver using what I have learned from you and reading C. M Hoke's book as you also suggested I read....and when you refine platinum you also told me to look up platinosis.....I for one will never attempt a platinum refine....and for that I can say thanks for saving my life...I have fear for you when you do platinum refines...thanks for everything Sreetips.
It’s scary stuff.
The Bob Ross of home metal refining. Thanks for sharing. It keeps me from burning my house down or my eyebrows off.
You're a brave man sreetips, but your effort and attention to detail is incredible. Thanks for reminding everyone that Pt chemistry is NOT for the inexperienced. And you're right - a glovebox is probably the go if anyone really insists on doing experiments with PGMs.
Yeah he reminds me of my grandpa with how thorough and knowledgeable he is. My gramps was an esteemed organic chemist :)
I just recently started watching your channel, and I've always wanted to learn how to melt metals and make my own my creations, but I don't have steady hands and don't need to jack up my fingers or spill any dangerous acids around me or blow myself up with all the gases and a spark close to me, So I'll watch you instead, really enjoy how you explain and show. Thank You Sir.
Well you taught a geochemist of 32 years a new thing today! I had never heard of the flame trick with Pt. Thank you very much! I've always told my crews that the day you stop learning is the day you start dying.
Hay rock - maybe see you Monday
Palladium alloys react same way with flame, tested on 20%Pd 80%Ag alloy, and higher Pd content. Such material was very common in soviet potentiometers, rheochords - even polarized relays. If Pd content is much higher - it gets some blue tint.
A Platinum refining Bromate hydrolysis series? Life is good!
A joy to see!
Love the old Craftsman vise Sree. Reminded me of the one my Dad had on his work bench up in the barn. Memories , eh?
I'm glad you continue to re-emphasise the safety aspect of refining Pt. I've seen many other videos where they mention it once but then that's it. For something this toxic it's good to keep bringing it up. I'm also not surprised that this isn't something you do much more often. I HATE working with Pt and will not do it. Any Pt I have goes right back into the stockpot and when there is enough to collect it just goes into a jar to be sent to the refiner at some point. With the added cost of the extra acids/reagents and time, coupled with the toxicity I'm actually surprised Pt isn't valued higher than it is. I do wonder though just how much Ir you have collected and sitting in various residues over the years. That's one recovery I'd like to see.
I can get the Pt and the Pd, anything beyond that is a complete enigma. Osmium scares me the most. It’s fumes tend to react with the eye lid tissues and form metallic osmium under the eye lids. Like having sand in your eyes for the rest of your life.
@@sreetipsI'll never play with osmium it'll stain your cornea forever.
Fascinating. Appreciate the fact you are doing this out of your comfort zone and documenting it.
@4:20 And that is why platinum is being used as a catalyst, since on its surface soot is getting oxidized to CO2. For a moment I was expecting to see Elvish writing there, that would vanish after cooling.
This is so dangerous to do. I must say your attention to detail and the research that goes into these experiments are just mind-blowingly amazing!! I thank you for sharing your life with us... I appreciate all the work that goes into the work you do...not only that but the work you an Mrs.StreeTips do to prepare for this ....again Sir Amazing... !!
Thanks again,
DonnaLynn Kawana
way cool !!!, cobalt chloride is pink and cobalt is a common platinum hardener,
the other common ones are iridium and ruthenium but they don't form red/pink chlorides according to Wikipedia, finally rhodium chloride is raspberry red but is typically only used to plate the platinum and would be present in minute quantities only, it will be very interesting if you are able to determine what the red is, and whether your process is good at separating out cobalt, iridium, and ruthenium from platinum. nice video !!!
That’s good to know. As usual I’m in uncharted territory. I hope that the bromate will complex with the cobalt during the hydrolysis.
Given how the cold rolling can encapsulate dirt and grime (if the flat rolling creates "laps" and/or "folds", so the material surface folding over on itself) I'd recommend to do the ultrasonic cleaning _BEFORE_ you do the flattening.
And then maybe afterwards too, for good measure, but definitely before flat rolling.
Can't wait to watch this video later. Haven't seen any platinum refineries done in a while. First thing I'm do when done cooking!
Your Platinum refining videos are always my favorite. Mostly because I know how difficult it is and how dangerous it is. I can't believe you're getting anywhere near those fumes. Baller.
Thank you for posting! You are my favorite and most enjoyable to watch refiner on youtube!
Man every video I watch has me so hooked. Thanks Mr sreetips for all the knowledge and great content to watch
Gooood evening from central Florida! Hope everyone has a great night! Nice to see no accidental distilled water rinses! 😎
Goooood evening!
You’re welcome. Thank you for going ahead with this intense demo. There seems to be a higher number of vultures in the air above me as I watch. They know something’s up! It’s all quite spectacular. Thank you Sir! 👍👍🤟
This is by far the best video that you have done to date.. This is so cool, I've never seen anything like this, please keep up the good work.
You need strong ventilation and full PPE, and preferably a respirator too. The danger of platinosis should never be underestimated.
That’s an awful lot of work for a beaker of coffee 😉
Kudos to you for going through the process so that you could be a good steward of the materials you’ve collected.
That went from a ring to a tiara. I've only flattened pennies with the help of a train before. Must be fun turning metal into tissue paper. 😂
Holy moly! those "Ducted Fume hood glove box" go from $500 up to $50,000!! I think we all want you safe over sorry. Hope you can afford one in the future. 8^) Love the vids and look forward to more.
Hi.
I found some platinum ore, and my friends have been bugging me to extract it.
After watching the struggle you are going through, and the high level of danger, I am perfectly happy leaving it as is. It looks really cool as is because it's a natural crystal sponge appearance.
I'd be interested to see if rolling out inquarted gold would allow for fewer Nitric boils or faster processing compared to chunky flakes.
With the gold you're trying to take out the silver and copper compressing it might make it harder
That might make a good video.
Indeed. The loosen it just anneal to redness and this will cause it to soften and relax. I’ll do a video on it.
Platinum is the 3 densest metal on Earth, Iridium is #2, that's why platinum doesn't change color...Also, that is the reason high end spark plugs are topped with platinum...Just a lil fyi MC...
Sreetips thanks you so much for giving us a very detailed and informative video they never get old. 💯👍🏽
I didn't know about that fire test for platinum .
I appreciate this platinum refining video series and It's very interesting seeing how you do it .
That's awesome, thank you.
Really a neat process that I may never try
Thanks for sharing 🍻✨️
Lookin good, love the strawberry shake. Another amazing video💥👍
Hello sir, as a pharmacist, one of the most dangerous jobs is to handle cis-plainum, cytostatic, used to cure cancer. Dangers and side effects go through the roof, but can save lives... Czech Republic was top producer of cisplatinum and carboplatinum, so, at the university that was an important topic. I do not plan to refine platinum at all... Thanks for showing it...
Hello Mrs and Mr sreetips. I simply love
when you put some clip out for us.
Thank you, and god bless you🌹
Arne
Awesome to see this series, i've been wondering about this. Kind of surprised you didn't use some of the old silver cell filter slimes and recover those as well.
Since he removed one of the rings at the start, since it would have been to much. I think not adding the silver cell filter slimes, was the correct choice since they would have a whole lot of different Elements as well which could have made it harder to refine / purify the platinum.
Perhabs you could alloy platinum with zinc as i have seen in Rhodium refining. 1 Part Rhodium + 10 parts zinc in a crucible covered completely with borax. Heat it in the oven to just a bit under the boiling point of zinc and stir. Then treating the cooled alloy with dilute Nitric acid dissolves the zinc and leaves Rhodium behind as black powder.
Nice! New Processes ... PLAT not some thing to mess around with .... Silver and Gold sure ... But Plat no thanks you can keep that stuff. The dangers are to great ...
😎😎
...I stopped breathing while you transferred the HNO³ from the storage into the little beaker while wearing surgical gloved. Brave man ;) And: Nice videos!!!
Thanks for having a go at refining the dreaded Platinum!
I appreciate that you are showing this process. I'll certainly never try it.
These 'get rich quick' videos.. Nice way to bring in the new year. Thanks for the entertainment!
Above all else, your persistence is a nice change to the got to have it now society. Great job and be safe.
The rose color is from the 10% iridium, because hexachloroiridate ions are dark red. Together with the 90% yellow platinum salt it makes sense that it would look pink.
Thanks for that. I’ve never seen iridium.
@@sreetips On the German Wikipedia page it says that ammonium hexachloroiridate is a dark red color. Separating this from the ammonium hexachloroplatinate is probably gonna be really difficult though.
Really enjoy the content, I’m glad I stumbled upon your channel. I usually watch like anything car related but you do such a good job, very entertaining fr
Wow Chief, thanks for showing us this operation, I think I wouldn't have attempted it. Keep the videos coming!
If I ever build my own Home I think of adding a refining shed to it, with a Lab portion and other possible needed or nice to have things as well. Just to experiment with some of these things as well.
Really interesting, I've learned lots about platinum from your video. That precipitation was really neat. Awesome video. 👍
I'd have stopped @ 6:55 with that amazing rolled Platinum necklace!
Seems like the platinum is one of, if not the, hardest ones to purify. This all is very fascinating to me though. Awesome content
Having watched some of the gold videos, I missed the little squirt of sulfuric acid "just in case". 😀
I am so glad You remembered to use Hal instead of water to rinse down the beaker
When You first went to rinse the beaker My heart leapt into the back of My throat when I first saw the squeeze bottle until You said it was Hydrochloric acid.
from platinum to flatinum XD love your work brother :) mad respect from the land down under
Man this is very interesting for sure. You are right though Sreetips you don't have the right set up for this experiment but fascinating nonetheless. Thank you can't wait for part 2.
It's great watching your work as it's so interesting watching the manipulation of the Noble metals.. 👍
As a fellow refiner, I can appreciate the use of precision cutters when bending metal. As an electrician, it makes my skin crawl.
I did that to save time. Platinum is soft, very similar to gold.
Excellent work. Great vid Sreetips, a great idea for a series.
another interesting thing about platinum is its a really good catalyst, so if you were to heat a coil of platinum wire to red heat (or a thin platinum coin) and hold it over acetone itll stay red because its causing the acetone vapors to undergo reactions keeping the platinum hot.
Didn’t know that
When you bumped the beaker with the dissolved platinum I felt for you. That must have scared the hell out of you loll
Hi Kevin, great work - I appreciate you took so hard topic. For sure Pt alloys may contained some Pd and all other PGM.
Pt-Ir is hard to dissolve - I am curious about any solid you will get - Ir may be there after dissolving in aqua regia. There is few way to speed up this - make an alloy with silver and dissolve most of silver in hot but not too concentrated sulfuric acid. Pt would dissolve in nitric partially. Pt-Ir10 and pure Pt [contacts] reacted different with boiling nitric - Pt was dull and darker - Pt-Ir10 was shiny as before. Using HCl with hydrogen peroxide is much faster for Pt / Pd - but silver in alloy makes this problematic. It is much easier to get Pt/Pd into solution completely if they are dropped before with formic acid [I know, still they must be dissolved first].
In general I strongly recommend use of distillation setup for such task. Flask from good quality glass with heating mantle and reflux condenser, with constant flow of cold water. Heat can be set to keep gently boiling, key is to have efficient condenser. Amount of metal lost this way is minimal. If you need to remove excess of nitric, distillate can be gathered and any precious dropped with aluminum.
Fumes of Pt/Pd chlorides are nasty - but glove-box or fume hood is not the proper protection itself, without scrubber. Even if vapors will be sucked, they will eat any unpainted metal part after they condense or make very precious fallout in the neighborhood. Best way is not to let them go away from reactor vessel, never operate hot solutions, carefully drop PGM with Al/Zn [never ever let them become hotter than 60*C, they start vaporize PGM].
Can't wait to see final results ;-)
I’m in over my head. In part three, evaporating off to denoxx, I looked away to get the camera set up. I came back out and the solution was close to dryness on high heat. I shut it down and went to bed.
Honestly sreetips you could make the fume hood you have into one that has gloves. Is it a glass window or plexiglass? If it is glass see if you can get a plexiglass sheet. Then cut holes for the gloves create a gasket with silicone and bolt on a piece that grips the end of the gloves and clamps it to the plexiglass
another thing, if you were to do this quite a bit more often youd definitly want to get a reflux setup, as itll save your acid and your money. for those who dont know what a reflux setup is its similar to a distilation apparatus but instead of distilling the liquids off into another container you let the liquid drop right back into the boiling flask, good for when you have to heat something in an acid for extended period of time.
6:47 Metal Rolling Machine™ is the sincerest form of flattery!
That 200K is impressive. Congratulations.
It's funny how you seem to do all the topics of refining I was just thinking about two days prior
Great video. Never realized how resistant Pt is to AR.
this,i,didn't know that doing this was a big danger to you or anyone else that might try this it's still an interesting process and very rime consuming just to get it to break down .thank you for sharing looking forward to part 2.
Just seen the end result - the red precipitate rather than bright yellow ammonium hexachloroplatinate complex salt. Do you think that's the tetrachloroplatinate ion instead??? Or both. Been thinking about it - you boiled it right down to that syrup for a long time which might have forced it from the (IV) into the (II) oxidation state and the tetrahedral form which is red/magenta as a salt. Never seen it in person - a new one for me - cool work and a great colour. If it is, it means there's slightly more Pt by mass in the precipitate.
(checked my old texts- chloroplatinic acid above a critical temp/molar mass seems to drive off HCl and force the tetrachloride)
If I did that then it was by accident. Someone said the iridium forms a red colored precipitate.
For watching?? Thank you for posting, and forever grateful. Need more equip?
Considered this awhile back, lucky it never came to fruition.
After reading the osmium comment, it's a partial pressure glove box or sux a tranny's BBC.
Air circulation may have prevented visible vapor, was the nitric fuming?
They should have had Walter W. in Breaking B@d, have a lab screw up w/ this stuff. Like the phosgene gas in season one.
I've got hundreds of vacuum tubes, from an estate of a TV repairman.
Suggestions a/o local to NC?
This is extremely interesting to watch, but it suddenly gets VERY real when Sreetips gets the splash back on the glass beaker. Oh man, that's all takes, one drop 😲
That’s right
Hey sreetips I did not expect this. Thanks man.
I noticed this is the first time I've ever seen you use a front fume box face body shield... that's the only thing you ever have done that I worried about you... that and your room is not positive pressure 2 help push the fumes up and out of your vent hood... your a fantastic chemist, and this is the only time I've ever mention any faults in your work.. after 30-50 ish comments...so just know I'm not trolling... simply helping out someone I respect.... it may look like all the fumes are going out your hood from the nitric hydro boils..etc... but the heavy fumes boil up and over then down settle on the bottom of fume hood... then roll over 2 the floor/room your standing in..... you can't see them but their their....
There is a baffle mounted on the back of the hood. It transmits the vacuum to the floor of the fume hood and pulls those heavier-than-air fumes up through a channel under the the baffle. If I had acid fumes leaking into my garage then my lawn mower would look like a pile of rust!
Looks like you got it covered then.. smiley face.
My employer scraped about 30 type R thermocouples last month, unfortunately when I pulled them from the dumpster someone had already crudely clipped all the 0.5mm platinum and platinum/rhodium wire, I estimate each thermocouple contained approx 400mm of pure platinum wire and another 400mm of 90/10 platinum/rhodium wire (What a score that would have been).
I collected all the remaining ceramic terminals which contained the stubs of platinum crimped into copper connectors that I'll dissolve in nitric acid and save for future projects, like reducing platinum onto a quartz wool catalyst, if I can safely deal with the chemistry, I didn't know how dangerous platinum salts are!
Would have been a nice score
I've been waiting a long time for this video!
Whoa! That was intense. Hats off to you, sir.
Seeing you working with platinum reminds me of nightmares I had. Sure looks painfull to work with.
Forbidden milkshake
always aswome my friend i think you're find you're way continue like this , you are the best , vincent
If someone really wanted to, they could take a sheet of suitable material, install gloves, and cut it to fit in the opening of the fume hood. Then, some simple latches or clamps could hold it in place.
It seems once you're into gold refining, it's hard to avoid refining the other precious metals because they accumulate in the refining waste. But platinum seems like the one you should avoid the most. Platinosis sounds really scary.
Dont you think he'd be familiar at least with Argyria if he was careless ? ;)
Interesting though, I can think of many other metals used in jewelry / silverware that would scare me more
Thanks, Sreetips... You mentioned early on that the thinner you could roll it out the shorter time it would take to go into the solution. What if you stacked the thin strips on top of each other to get them to thin each other out some more? Could possibly even cut the thinned strips into shorter segments to stack even more pieces to get them to thin out even more...
Stacking is a good idea
fantastic to watch :) just fascinating :) and incredible at the same time :)
I sure like the sound quality improvement. With your new hood.
4 I've learned a lot from your videos.
Watching now… Curious how this refining will go because platinum seems to be agrovating…
If I had to guess the reason that the precipitate is res is because it’s is the tetrachloro platinum salt instead of the hexachloro platinum salt which is yellow.
that iridium is making that alloy waaay harder to dissolve than pure platinum.
Uncle sreetips is one of the best teachers on yt
SO PAY ATTENTION!
I've said it before not for me I will stick to gold and silver thank you for sharing this six stars brother
The best thing to do here is use way more hydrochloric and way more nitric than anticipated,
that way you avoid playing around with the solutions as much as possible.
The worse that can happen is having to do some extra evaporation, but you did that step anyway when killing the nitric.
If I try this again I’ll use a reflux condenser and addition funnel.
@@sreetips Excellent
A good way to explain or describe the glove box you’d like to use would be what you see Homer Simpson working in during the intro scene from The Simpsons.
Fascinating!
Dangerous stuff though!
That was pretty badass Sreetips! What comes next? Plutonium refining?
Thinking back to HS & college chemistry classes, we never had fume hoods and used acids & aqua regia. Us gen X's should sue!
Excellent video once again thank you 😊
1.3K+👍 's up sreetips thank you for sharing 🤠
Nice one Mr S. Stay safe buddy...😊
Sir I notice that on your video @11:00, you didn't tag your name on the hot pot. I think on the front side looks real good there Sir. 😀
1 or 2 is good no need to put the channel name on everything in frame. Your channel is awesome no need for the over advertising. Great vid.
It’s not advertising. It’s to prevent thieves from re-uploading my videos as their own creation.
There are two hobbies that scared me chemistry in metal working LATHES. Would it be possible for you to go over some of the chemicals and precautions and some of the dangers
Fumes. No way to safely do these reactions without a fume hood
@Sreetips, do you think perhaps the platinum in this case was so resistant to the Aqua Regia because it was rolled? Perhaps that made certain sections of the strips more dense? Or does the metal just take THAT much abuse before it breaks down and goes into solution? I was wondering if it might be a good idea (for platinum only) to perhaps flake or shave the metal before boiling. Would there be a way to fragment it into a 'iron filings' consistency with some sort of tool? Get the particles really small so it might give more surface area to the aqua regia? My other question was whether the iridium made it more stable in the acid. Or perhaps if there are even other alloy components other than iridium that might have been in there?
I dissolved a small piece of Pt 1/10 of a gram to make my standard test solution. It took me six hours and there was still a small piece left undissolved after that. Platinum doesn’t cooperate at any level.
