I really liked the fact that you showed the boil over. I have had many of these throughout my chemistry career and this is just part of lab work. It happens. I have had fires and minor explosions as well.
Great work man. I've been into refining PM's the last 2 and a half years and when I say I've seen it all here on RU-vid I mean it. You definitely have the most detailed easy going videos. Great work man. Your recovering gold from dirty solutions clip saved me from backing away from all of this and allowed me to completely clean out / recover & refine all the PM's I had in a 3 gallon container full with dirty solution in it. Again. Great work man. People like you give me hope.
In regards to the mishap you had at around 10:00, I just wanted to say that I appreciate you sharing details and footage like that. Most videos that are uploaded that cover chemistry (and I suppose science in general) only show the ideal situations and favorable outcomes. But in my opinion, we learn more from the mistakes/failures/errors than we do from the perfectly successful outcomes, so cutting footage like that does more harm than good. Channels like CodysLab, NileRed, NurdRage, DougsLab, etc, are some of the few that include the mistakes that others would consider "outtakes", and I think that's awesome. People learn more from mistakes, and I prefer learning from somebody elses mistakes whenever possible, haha. So yeah, thanks!
You learn more from your mistakes and mishaps than from anything else. Your "Keep calm and carry on" attitude is a fine example of how to deal with those teachable mishaps. Bravo!
Very NICE!!! I've been wondering about palladium I've heard it was a harder metal to get! You're doing GREAT! If someone would've asked me 5 years ago if I could sit and watch, pretty much a chemistry class for long periods of time I would've told them their nuts! Funny how things change!! You're extremely informative!!!!!
@@joeowens173 Over the past year I've learned more about platinum group metals! I'm nowhere near where I need to be but I'm learning everyday!! Thank You for your response!!
@@joeowens173 Do you refine like Sreetips? If yes do you mind if I keep your name for when I start to recover and refine then have a question? I've been collecting and hoarding for almost 3 years. I told myself from the beginning that I don't want to jump the gun and start to soon just because I have a lot to recover from! Oh, I should mention that 99% of my hoard is ewaste. I know it's frowned upon, but I get it free and most of the time it's dropped off at my door! I see people that start to recover and refine when they get their first pound of pins or fingers, I don't want to get sick for being greedy and refining before I'm ready with the knowledge I need!!!
11:40 I know this is old AF and you may have learned this by now, but this is where you use a Glass Rod to help you pour, as the surface tension of the liquid will attract the poured liquid to the rod instead of the side of the container, when you pour while laying the rod across the lid of the container. Just gently hold the end of a rod against the poured edge from an angle close to perpendicular to the side.
Your videos are great. A few ml of ice cold distilled water could have stopped that runaway and then plunging the beaker into a bowl of ice water. You could learn by putting the beaker further back to contain the over spill from the spout. Think you handled it very well and the people probably don't understand just how dangerous hot aqua regia is. There is also a glyceregia version made with glycerine that we used in metallographic etching.
Julian, I've learned, from this boil over, to always use a beaker that is much larger than I think I'll need by at least a factor of two. And even greater if I'm working with PGMs.
A lot more involved than I anticipated, sreetips, but definitely doable. It's looking like strong coffee at this point, and I'm off to PT. 3 and I can't wait to see how things turn out in part three. Your knowledge is very impressive, you have a great mind. I'd bet you have a ton of general knowledge and would make excellent conversations!
I appreciate you leaving the boil over in the video. Knowing how difficult it is to judge reactions is something not shared enough. I started refining about 4 years ago, i haven't done too much in the last year. Anyways, another great video friend.
It does not get any more real than this. Thanks sreetips for the success and the splashes. I've been binge watching your videos over the last few weeks.
Thanks for the sharing bro..I just started to refine pt and pd..I just used to purify silver and gold for the past 2 years and now I have 2 drums of used acid which i beleive they contain some other pgm including Nickle and cu..Ive been watching your videos from Ifugao Philippines since no one here is doing puridication to aid me..
I know how you feel. I add those waste solutions that contain traces of Pt and Pd to my stock pot. The stock pot is full of clean copper. In there, the traces of platinum metals cement out on the copper and collects as a fine black powder that accumulates in the bottom of the bucket. The nickel, being more reactive than the copper, will not cement out on the copper. The nickel stays in solution. This give a good separation between the PGMs and the nickel.
Been watching for a while, and haven't seen Sreetips have a boil over that wasn't intentional (the last Palladium silver cell slimes video was the first time). I'm not a chemist, but I like that we can see where things can go wrong, and they aren't edited out. It's experimentation, and it should be 100% honest, and if it gets messy, it gets messy. Thanks for this.
Get a hotplate/stirrer. It will reduce your processing time a lot. Biggest problem in Chemistry is getting the chemicals to hit each other. Most of that peroxide decomposed into oxygen and water before it had a chance.
I'd love to have one with a sturdy Teflon stir bar. Part two is uploading right now. Wait until you see that fluffy bright yellow precipitate form as if by majic from a clear blue solution as I add the hydrochloric acid. It's absolutely beautiful. The colors are so vivid!
My only knowledge of paladium is from the Marel Iron Man movies so that is to say I am totally ignorant about it. What is the value of paladium and what are the applications? Thans again Sreetips for sharing all your knowledge. This is way more enjoyable than a science class. hahaha Cheers
Palladium value per Troy ounce can be found on kitco.com it’s one of the six metals in the platinum group: platinum, palladium, rhodium, iridium, ruthenium, and osmium. Palladium is used as a wash coat on the ceramic substrate of automotive catalytic converters. Like the other PGMs, it has a high melt temp, is very non reactive, and resists corrosion. Palladium is used to alloy with pure gold to make “white gold”. It’s the only one of the six sister metals that is soluble in just nitric acid.
@@sreetips Thank you. I had no idea. So...just to be clear you can't use palladium as a core for a miniaturized arc reactor embedded in your chest? hahaha
Patreon takes 30% off of the contribution. If you donate on PayPal he gets to keep all of the contribution and it can be set up as a monthly contribution.
Are there other methods to precipitate the palladium ? And have you ever thought about doing a video in refining Monolithic Capacitors from computer boards , if would be a cool video , you would probably have to use a hammer to grind the Capacitors into a powder , but I feel like it would be a worthwhile video.
I found this channel just the other day, and I think I've logged probably 8 hours just watching. I would be interested in you having a private class where I could just fly out and learn the process first hand. Having the videos are great, but with chemistry, things can go wrong very fast. Plus, Im more of a hands on type guy.
There is no substitute for experience. I started via trial and error and by joining the goldrefiningforum.com about eight years ago. Unfortunately I'm not set up to offer such a class. But I would be happy to answer any questions that you may have about this subject.
The book you mentioned a few months ago, I have the link saved in my favorites, I would like to know, is it laid out in approx same fashion or order of how you run through your RU-vid shows?... Is it easier to follow along in kinda of a step by step, with lots of info, to assist me in not screwing things up, lol.. My other chemistry books, are an absolute pain in the a$$ to keep in the head.... A step by step book for these processes would be priceless!! Nice job on the video again...
Dru, it does have a similar fashion as my youtube videos. Its a little dated on the procedures. For example she says to pour waste down the drain and flush with plenty of water to protect the pipes. it's called Refining Precious Metal Wastes by C.M. Hoke. Search for "Hoke" on Gesswein.com for about $65. It is written in nontechnical plain language. But it is still kind of hard to follow because the author skips around and references a process from a previous chapter within the current process that she is describing. But that aside, it contains a wealth of information, has a good index, and is nothing like a chemistry text book. If you are refining at any level then it's a book that you must have.
I am astonished about your techniques and that you learnt them all on your own with the help of some books. You are doing nice experiments... you are using g and mg. You are using mL and L.... but why do you still use °F?!?! And you are producing LOTS of heavy metal waste..... I hope you do know how to clean them up so you can put most of the waste into the sewer. Regards from an M.Sc. in chemistry
Much credit must be given to my teachers on the goldrefiningforum.com I started using degrees C, but in USA they use degrees F, so for their benefit, and yours, I now give both. Every drop gets treated before disposal. Everything gets cemented out on iron and processed to an inert state. Nothing toxic gets poured down the sewer. Please see my waste treatment video.
My problem is how to separate the Nickle from pd..i have collected at least 20kg hard drive disc..after watching your video on how you refine the platinum from hard drive i how have an idea on how to separate the ni from pt and pd..thanks again bro..
Also, when the palladium/pt salts are in the precipitated form prior to being dissolved by ammonia and precipitated by hcl. What is the technical name of that form? Prior to hexochloropalladate.
By the way where did you get that cool big volume pipette? I’ve looked all over online for something like that and can’t find it. Maybe I don’t know how to describe it correctly for a search
I found those years ago at a surplus lab supply eBay site. Had to look it up: americanlabindusrtysurplus - they used to have awesome specialty glassware. I bought three of those, one each for gold, silver, and PGMs. I’d spend hours browsing their listings. I bought a bunch of items from them that I’ll never use.
When you cemented the palladium out with zinc, why did you have to re-dissolve it and then precipitate it out again with chlorine gas? Couldn’t you have avoided that whole process by melting the black cemented palladium powder? I’m sure there’s a reason but I’m not seeing it logically. I imagine there’s probably a difference between the black cemented powder and the calcined palladium that was precipitated with chlorine gas But what confuses me about that is you call it pure palladium powder that was cemented out with the zinc. So why the extra steps?
I like your videos. I have been researching information about refining palladium contacts I have been removing from 1970 Telecommunication wire relays and crossbar switches. I don't think I'm going to try myself, but if you are interested in making a video on it maybe we could work something out. I have a few pounds of them, and I am expecting the pd yield to be between 1/3 to 1/2 of that.
@@sreetips I think it should be between 1 and 2 lbs of palladium. I have about 150,000 contacts, almost 4lbs of cut contact material at the moment. Should be over 5lbs when I finish the rest. Im hoping to get enough PD to make a kilo bar.
Hello, My name is Guy, I'm 3/4 into the video, I have some questions that I want to ask before I forget, first, I have a stockpile of small square capacitors From circuit boards (witch the name Eludes me) and I want to learn to extract The palladium, I am new at this and have not attempted any type of extraction as of yet but I'm getting ready to do it, Palladium, You said you get it from silver cell's, What are silver cell's? Also the Small Brown and square capacitors on circuit boards Have palladium, Do you know how to extract the palladium From these capacitors? I will have more questions I'm sure, thank you for your answers in advance.
@Sreetips, I know you said you can't sell your copper... Would you consider a commission for two approx 10lb copper ingots? There's a reason I want them, but I don't want to type it on here.
Forgive me a dumb question, but wouldn’t a hot plate with magnetic stirring speed things up in several places while doing this? Instead of a plain hot plate?
@@sreetips Clearly, you are not well acquainted with Marines… “Can’t I just smack [the rocket] with a hammer to seat it on the rail?” (Actual question I overheard when I was a UH-1N crew chief, from a new guy loading up a nearby Cobra attack helicopter.) He was subsequently hit with said hammer by his Sergeant…
Sreetips you are correct sure the experiment might have gone off without a hitch I want argu that but I am right there with you watching the video and its as close as I will ever come to refining anything. Perhaps I could start with refining my grammar skills! Right? Sreetips thanks man I appreciate the time and effort you put into your videos and you treat the video with more value than the metal. I believe you do that Instinctively because you know the video is a connection with people like your heard ie people who click with you. The metal well its just metal but that camera takes on an Entity of its own and ... well you check it out brother I have a very small channel no particular content just what ever but check it out and you will see you are lightyears away from 99.999% of people who are interacting with you such as me. Ok I took the long way around the mountain to say thanks for the video sir.
Your disasters are very informative! The only one is not ashamed to show them. THANKS! Are you sure that the gnomes in your workshop are able to read and do not steal your tools? I noticed that some tools are not signed - be careful! ;)
Do you by any chance follow a procedure or have looked at any articles about the recovery of Pd, Pt or Rh from catalytic converters? I’m very interested in this kind of stuff, and would like to one day try to refine those metals with great purity and with a high percent recovery.
I studied on the goldrefiningforum.com and with their help was able to come up with this technique to get pure platinum and palladium. Most platinum refiners are very secretive about their processes. Also, working with these metals in solution is very dangerous. They are some of the most potent skin sensitizers known. Get it on you and the effects are irreversible and may take months or years to show up.
I remember the boil over from the last time! Very sensitive process!! This might be a question that you might roll your eyes, but because of my lack of knowledge of it is why I'm asking! Do you think you could or would ever mess with the metal rhodium?? I've learned a "little" about this metal, I see it's up to $5,505.00 per ounce today and I know it's melting temp is around 3,400 degrees and also I learned it's a good thing to plate jewelry with, especially for those that have sensitive skin! Since you're in the jewelry business I figured you'd know alot about this metal. Being the price is so high it would get the attention of people who invest in precious metals!! Have a GREAT Day, My Friend!!!!
@@sreetips I am guessing quite dangerous!! Probably alot more dangerous than paladium, I would think! Good to hear from you and I'm enjoying your vids again!!!
I did a video on silver cell anode basket slimes. In that vid I show how to extract silver and palladium from a nitric solution. The silver and palladium get separated in that video.
Hello Boss! Could you tell me how to convert Palladium Chloride into Palladium metal? I got some palladium chloride, while refining silver, by using salt and making silver chloride, some of palladium chloride II shows up making this.
a while back I followed your procedure making the crystals from .925 stuff spoons candlesticks etc. my question is would there be any palladium in that stuff I ended up with 3+ lbs of crystals wondering if I should dissolve it again and try to drop pall from it not really sure where to get dmg from without big hassle most is really expensive and from Russia on ebay
Hello, I'm going back thru the posts and seen yours. Silver is a carrier of platinum group metals and gold. Especially older pieces of silver. Palladium tends to follow the silver through these processes because, like silver, palladium is soluble in nitric acid. The only one of the six sister metals in the platinum group that is. For this reason care must be taken to ensure the palladium does not build up in the cell. One way to help is to remove the palladium from the silver solution with DMG (pricey) before cementing the silver on copper.
Hi the video’s are very helpful I have a question on this video can you melt the black powder as is or do you need to make it into pd salts before you melt
Zinc is more reactive and much faster than copper. But zinc will cement copper also and contaminate the palladium. Notice the blue color when I precipitate the palladium from the ammonia. Blue is copper. (Edited once to add comment and correct a word).
Yes! Adding some sodium carbonate (swimming pool pH UP) will get rid of some of the acid and prevent excess consumption of the zinc. I forgot to do it in the video - due to my lack of experience.
No, I don't think so. Or maybe, after that first 1.5ml dose with stirring may have set it off sooner, with less acid. Either way, stirring would have helped. I need to remember that when doing these reactions - I've got a nice hot plate stirrer.
Just an FYI. If you are in the USA or most other western countries, because you are monetized on YT, regulations apply to your lab setup. No matter how "clean" your glassware, etc. may be, it is illegal to store foods/drinks (even unopened cans of soda/pop) in the same refrigerator... it has been that way since the 1970's whern I started college for my chemistry career. The gov't agencies may also go after those who have a lab for scrapping purposes (since you get paid for your refined scrap -- in the past they have even fined people who are pure hobbyists. Simple rule: No food or drink in lab. Period. It will save you from fines and possibly even from poisoning.
Hi, i have 2 kg of fine iron and PGM and Au mix. 97 % are iron. May i know how i can separate the iron first before going for other chemistry to extract pgm.
@@sreetips sir, very kind of you to answer me as you have so many subscribers. Give me a chance to thank you. The sample ore i have come out of ballmill and shaker table. Lots more if a good recovery is used. Email me pls thank you.
Actually it's neither. That dried black powder is actually metal in powder form, but it's mixed with platinum and possibly other metals. It's not pure. I've got part 2 uploading as I write. I got a nice pure palladium button 3.6 grams in part 2.
Any zinc metal will work. But small thin solid strips twisted so they don't lay flat will provide more surface area to the solution and make things happen quicker.
question about my stannous chloride I got it in crystals at purchase I added water to it its milky and when I do tests it like bleaches solution on test strip is it not diluted enough or too diluted
1 gram stannous crystals. 1 gram tin shot. 25ml distilled water. 30 drops HCl. Use immediately. Mine turns milky after a while but works fine for up to three months.
I know you said you didn't remember the name of the company in ohio where you bought your zinc scrap. If you can't remember then name, can you remember the products they produced and/or the city? Was it zinc Roof Flashing or gutters/downspouts? I will be looking for a zinc source for processing PGMs when I'm am ready.
Thanks, that was what I was figuring. It will still be a while yet before I’m ready, but wanted to get all my ducks in a row first for supplies. PGMs are a big step Up from gold and silver and I’m still in the studying/learning stage. Platinosis is nothing to take lightly.
Your last clip kind of answered my question, but I will pose it anyway. I know you have called this a hobby, but is it at all profitable? I have no ability to do this myself, but I am simply curious. All the acids, melt dishes, glassware and metal acquisitions seems like it would be difficult to break even let alone realize a profit. Thanks for the videos, they are very entertaining and educational!
Karat scrap is profitable. The yields are up around 50% to 60% and I get it for pennies at yard sales, thrift stores, consignment shops, and even goodwill. The only other thing that is profitable about all this is the ad revenue that I collect monthly from Google. It would be very difficult making a profit from computer scrap, unless you could get lots of it for free. But the yields are too low and the waste is high!
