Next step add a little nitric to your platinum solution and reflux to get the nasty iridium colloid to disolve. When a laser pointer does not show a visible beam in it its ready. Next dilute it and boil down to remove the nitric acid and add a little extra HCl toward the end and dilute it a lot. After this boil until it isnt giving off very much HCl vapors. Some is OK though. Chill the solution then add concentrated ammonia slowly with rapid stirring until PH of 9 is reached. Then vacuum filter the precipitate out rinsing with ice water. Do not exceed ph of 9 or else your cisplatinum dichlorodiamine complex ( say that 3 times fast) will isomerize into the trans isomer which is much more soluble. The precipitate should be a yellowish color and your filtrate should be yellow to orange. Next add your sodium bromate and hydrochloric acud in the filtrate under mild heat until you get close to neutral PH. The iridium will drop out as a reddish complex or free metal (if you heat it too strongly) and any platinum will stay in solution. Make something cool for mrs streettips for letting you abuse her corelle ware 😂
"Do not exceed ph of 9 or else your cisplatinum dichlorodiamine complex ( say that 3 times fast) will isomerize into the trans isomer which is much more soluble. " Letting a cis-platinum become a trans-isomer? Oh heaven forfend from that happening! Minds would explode! (Sorry, I saw the opportunity for a cheap laugh.)
This has been a great series and has proven to me that my decision to not work with PGMs to be the right choice. I just grab the gold and silver and everything else goes in the stockpot. When I clean out the stockpot I just recover any silver or gold and everything else goes back onto copper. Once I have a decent amount it gets sold. I don't get as much for it not being refined but I'm done working with the stuff. Kudos to you for your time, effort and skills.
I just love watching these vids it sometimes can relax me when nothing else will even though I not even remotely a chemist like this man. It is sort of like making my breakfast sausage gravy.
Testing the limits of the CorningWare dish with that torch! I wouldn't have dared to do it, but it's great to see that they can even sustain this effortlessly. Calling it a "reaction dish" was a nice touch! :)
Iridium is pretty amazing. I see you can heat it up to 2200° and anything that remains unmelted is Irridium. I.E. Iridium melting point is 2400°, It being black near Solution and cannot be puti nto solution with Acids is a cool piece of Trivia. Your channel is extra cool. Your local high school chem teacher should badger you for weekly Visits to his/her lab
I'm not familiar with iridium, but I looked it up and I see that it is used as a hardening agent for platinum. If I recall you had a few pieces of material in Part 1 video that did not go into solution. It looks like iridium is insoluble in acids or aqua regia. I think your right about iridium. Also, it's a very expensive material. Hope you can get it into an ingot. Enjoy your videos and many thanks.
i have been watching you for years now and ive always wondered if any precious metal are lost in vapour, if so your hood filter must have some in ? just a thought i know nothing, love your vids ty
You are welcome. This is Definitely a process that produces irritatium…out of thin air! On the plus side it makes refining the money metals seem like a cake walk. Looking forward to seeing the next instalment. Thank you Sir!👍👍🤟
Out of interest. How rare is Iridium? never really seen PGM refining before and I don't do refining myself but that's the first time I've seen Sreetips, find iridium. I love the longer. more parts videos. If you do a long series like 8 parts a suggestion, compile them and edit them down somewhat for people who want shorter form video.
I checked into renting one ten years ago. $4500 per month, $1500 per week. Includes a curtesy visit from local authorities to ensure it’s being properly used.
@@sreetips Holy moly, that price! Some owners could use that visit from an NRC agent though, I've watched people in RU-vid videos hold samples against the gun with their fingers and centimeters away from their midsection. Even if the blast of x-rays isn't all that powerful, it's still pretty crazy to use an XRF gun with as little caution as one would use a barcode scanner.
Just out of curiosity why don't you melt the iridium powder in the electric furnace to convert it to a metal or is it not ready to metalise just yet atleast if you can do it, it will no longer be a dangerous powder
That black stuff is interesting. You used aqua regia to initially dissolve the platinum but iridium should not go into solution with platinum, not every pgm follows platinum. Shouldn't be osmium either. My guess is it's rhodium which is often used to plate white metals, although I can't understand why it would be used to plate high percentage platinum alloys.
Osmium won't, but iridium will go into solution if finely divided and refluxed in aqua regia. I'm pretty sure the powder is mostly iridium. Ime it tends to form a horrible colloid suspension from Pt90 Ir10. One method is converting to sponge, then electrolysis of the sponge on a graphite anode in chloroplatinic acid and HCl. The trick is using gun cotton or another acid resistant material to wrap the sponge tightly on the anode. You also get easy to melt platinum crystals on the cathode. ❤
@@christopherleubner6633 Interesting. I haven't done too many platinum with iridium but have had it left over in my beaker with old watch cases and bands from the early 1900's.
Some of the platinum jewelry that I started with was marked “100 iridium 900 platinum” so I understand that iridium is a common hardener for platinum jewelry.
You might take dropper samples onto your white porcelain multisample tray and try pH, chloride solutions and whatever other precipitates you know of. Observe each for reaction, precipitates. Maybe you can bubble sulfur, from your h2so4, metabisulfite rig to precipitate a sulfide of platinum? That can just be burnt off into Pt. Just taking a wild guess. Saw that still no metal bar at the end so why not. Not even sure what ions you have in what pH. 🥈🤯
I've had a bottle of 30% hydrogen peroxide in my big freezer for more than 20 years. It's still staying liquid in the freezer, so I assume it hasn't lost much strength.
Stree, what do you mean by “real” diamonds? Do you mean natural diamonds? You can’t guarantee those are natural diamonds even with a diamond tester, could be a lab diamond which is “real” but isn’t worth anything, or a moissanite which is worth even less. You’d need to take it to a jeweler who has a lab/natural diamond scanner. Those machines can be anywhere from 2000-15000$ With my experience, judging by the 10k gold setting, those are likely not natural diamonds, I suspect moissanite unfortunately
I just had an idea. You could pipe the exhaust of your vacuum pump into the fume hood, and then you wouldn't have to worry about it polluting the lab with platinum fumes.
@@sreetips Do you have a bubbler attached between the vacuum flask and the pump? I don't know how the acidic air/chemicals would react to the water. I used one to help keep sodium hydroxide out of the vacuum source. great videos.
If I may make a suggestion? Why don't you divide a relativevy small part of the platinated solution you are going to use in, say, 10 equal parts (say 10 parts of 10ml each) and try out different concentrations of reagents on each part, keeping track of the concentrations used. The one that gives you the best result, should be the one you use to extrapolate to greater quantities and to refine the concntrations used It's not perfect a methodology I agree. Doing your homework and some research on the subject though, seems in order :) Either way, I'll follow your progress with interest (and I'm sure many will)
Hey I have a future project for you.. I have my own rockhounding channel and I have a bunch of cool rocks bit I have a massive galena chunk. Let’s see what you can do on the silver recovery I’ll send it to you.
Ican wear a 🦌 deer as a cape after skinning it, i do hazmat and crime scene cleaning, i couldn't watch the dental refining Sreetips 🤠. Sorry but I can't watch 😂 yuck . Great Video Sreetips 🏴☠️🐉Nice Alchemy 😎
I can use jewelers bobbing compound on a buffing wheel. But that stuff really hogs out the gold. So much so, that f you hold it in one spot too long, it will completely wear the gold away.
Decorum and youtube rules prevent tme from accurately describing what that product on the slurpee straws looks like. I've seen you work magik so many times before... eargerly awaiting thatt part.
@@sreetips don't get me wrong. I love the science. I've gone so far as to share your videos with the caption "if chemistry class had included this I wouldn't have skipped so many classes". I'm always amazed by the various interactions of the chemicals. With my greatest wonder that it's possible to evaporate the chemicals to be inside out. To be able to present gold as a liquid that the evaporated contents are smaller than the total volume of the contents. Where the resulting bar is bigger than the liquid. Your knowledge and your search for additional knowledge is noteworthy and it's why I keep coming back. Please do keep creating these videos. BTW. How's the Beast doing?
Na, AI will only know what humans tell it. And platinum refining humans will NOT be eager to divulge their secrets. Especially to anyone (AI included) who will reveal their secrets to the masses.
That's not iridium. That's the iron that wouldn't dissolve well. I know you did something to mrs. Sreetips spinach pie. Haha But seriously, good work team
