You have helped me decide that this is not something i want to do. It is too dangerous and too hard and should be left to larger companys with proper employees who know what they are doing.
No kidding! "How hard can it be!? i said, i can do this! I said. Watched this amazing video and yea, ill leave this to the pros!😂 great videos! Love this channel!
What are you talking about ... It not dangerous .. it's a walk in the park ...just be smart , protect yourself . Leaving everything up to companies and the " professionals " is alot more dangerous that doing it yourself
@@sreetipsthey don’t give credit for the most expensive metal in that whole concoction of precious?!? Rhodium 😮 wt…😂 how much would you guess is in there? A grams worth?
"Take care of your equipment and it will take care of you." I've heard that a lot in my 21 year military career. Said it a lot as well. Nothing is more true than that! Love the videos.
I wish I knew more about chemistry. I won't attempt but found the video informative and appreciate all that hard work you did. Hopefully it was worth all that time in the end!
Being a HVAC man myself it did my heart good to see you change the oil in you vacuum pump...! Take care of your equipment and your equipment will take care of you is my motto also...
Yep as long as you change the oil frequently it will give you years of trouble free service. My Robinair is 30 years old and still pulls 30” of vacuum ...!
Im addicted to your videos I'm a watcher not a reader and I have learned so much by watching your videos ....I didn't know gold and silver can be turned into a liquid then back to a solid very cool stuff but I do agree about this process with the catylic converters it's not worth the health issues for such a small yield or any yield from this process.....but I do want to do this as a hobby to wish I could be a student ..... serious very serious about being your student ....I watch all kinds of videos and this refining of gold and silver done by u has sparked 100000% interest in it
That's some kind of work you did there!!! I think I'm with you regarding the platinum group metals! It does seem to be alot more challenging and definitely to dangerous to be doing it on a regular basis!!!
Wow, that's a ton of work going into recovering the PGM's from those catalytic converters. With the yield expectations being so low, it seems hardly worth so much effort. I guess we'll see when it all hits the melt dish! Thanks for going through the processing with us, I had always wanted to know how much precious metals are in those things.
I was wondering, have you ever tried to see your actual cost of materials and things in a run like this to see if you're coming out profitable. I know you do a ton of these things because they are exciting to you and I get really excited just watching you work, love how you're meticulous in all your actions, patience and doing it right the first time are or should be your mantra :). Keep up the awesome work :).
Snoozin, trying to do cats, in a back yard setup, could never be a profitable venture. The amount of metal recovered is small, waste production high, and it's too dangerous handling those toxic solutions. Plus the metals are difficult to separate, they don't cooperate.
I just watch this video. Haven't seen it since I posted it back in May 2018. I can't believe that I was able to do this. I don't know if I could do it again! Amazing.
Made to stop folks from doing it? Mark, nobody, and I mean nobody, who has it down, is going to show you their process on a social media like this. In fact if you look you will find that there is no other video, like this one, that shows the ENTIRE process start to finish, on the entire internet. Platinum refiners don't like to talk about their highly secretive techniques, and they don't like talking to people who do. By posting these videos, especially this one, I've made myself an outcast among the refining community. They wouldn't touch me with a ten foot pole because I've taken the time and effort to figure out how to do it on my own, then produced a video to show you what I have learned. They don't want their secrets divulged. Go ahead and check. You won't find another video with this much detail anywhere. I've got the only one on the planet! Plus if you look, I've got previous videos leading up to this one, where I refine a platinum coin for practice and some palladium to gain the experience required to make these catalytic converter videos. Thank you for taking the time to watch them!
Thanks for your time and energy, but were not worth the risk... I'm watching the gold video now.... I see you did t need me to tell you that platinum is not easy
Some things to improve your yeild, first it does not need to be terribly acidic, what the acid does is get the salts in solution, secondly actively agitating them will speed it up a lot, thirdly, adding a little bromine with the chlorine will strip it super fast. Also use some distilled water for your chemistry.
A+ just watched the whole thing in one sitting. This is the best video on the subject of catalytic converter refining wet, bar none that I have seen. Thank you for the great video, can't wait for part 2! :)
I've been was watching a lot of chemistry videos related to different homemade rocket fuels and their components, how to source and extract different chemicals and down a rabbit hole I went. I've been watching RUclips all morning on autoplay, but adding videos to the queue as I see fit. I hadn't noticed the videos I selected were finished until I heard your voice, and I literally gave my cats a fist pump. I missed you buddy. My brain was melting from watching all those amateur videos. You are now returning me to my preferred state of mind: Nerd zentastic. I gotta get back to housework. Ttyl
You are a wise man. Thanks for all the warnings of how terribly dangerous messing with platinum is. In Britain only recently there has been a spate of people cutting converters from car exhausts for the platinum. It’s not too much of a stretch to go from that to trying to melt them down etc.
Great video. It seems refining is a specialty all on its own and demands a bit of tenacity as well. I'm really curious to see how you will handle the final refining steps. Thanks for sharing the video, entertaining and interesting at once
Really interesting videos, many thanks. Glad such attention to risks, but one gentle note though e.g. for anyone reading the comments and thinking of doing this or similar - maybe consider using longer gloves.. in the video (from point of processing outside through into lab) we can see a fair bit of exposed skin between glove and sleeve.. when dropping bleach in from above ..or dropping the zinc pieces into toxic dissolved platinum solution there will be splash back ..if you’re worried about aerosols enough to put a lid on beakers to protect a fume cupboard, maybe that’s an aerosol risk to all skin surfaces exposed nearby. Of course it’s all a matter of dose.. and it’s not like you’re holding your arms above them all the time… but still, given the toxicity, maybe wise to reduce skin splash risk a bit more. If you can see the skin, it’s definitely not protected (and that’s before we get onto the weird and whacky issues with different glove types and different chemicals).good luck with it all and thanks for the videos.
thank you for the insight, was curious about what it took to accomplish this. one must definitely know what they're doing or risk serious injury and or death
When I remember right, cementing is not exactly dissolving zink by acid until the acid is gone. Normally the cementing starts electron by electron because of electro-negativity even in water ON the less noble metal in exchange of it. So you were right to give some Na-carbonate to lower the acidity to save zink. I wouldn`t use Ca-carbonate because you get a new element in solution and that may cause some trouble in an other place in the story, maybe NaOH to neutralize a little?? (Na is allready in the process.) I like your vids very much, especially the warning for dissolved metalls in terms of your health. best regards Olli
According to the pros, folks who do this for a living, sodium carbonate is the chemical to use. The exchange of electrons is called "cementing" because when copper is placed in an acidic silver nitrate solution, the resulting grey silver powder looks like wet cement. Some free nitric is required for the reaction to take place. I've put copper in a silver nitrate solution with the nitric used up so completely that the copper just sat there and no silver formed on it. To get the reaction started, I added a single ml of concentrated nitric acid then stirred. Then the reaction began. So some free nitric must be present to get the reaction going. This has been my experience.
Jes sir, that is right, a littlebit acid. Here you needed huge amounts of zink to kill the HCl , so my thoughts are to lower more with NaOH, not all!. Over here was an old copper-lead-zink mine from the 18 hundrets, where big copper trees got buildet on the old steel-rails from the ore-carts under water, the same process I guess. I do the same with my stockpot, copper tubes in it. After a while I check the PH and lower it if needed. Sodiumcarbonate Na2CO3 is a good choise either and cheap, it builds with 2HCl --> 2 NaCl (table salt) + CO2 gas + H2O so you get rid of the surplus of HCl. NaOH should do the same, just without the carbon dioxid. HCl + NaOh --> NaCl + H2O and the zink is doing Zn + 2 HCl --> ZnCl2 + H2 gas Is the H2 needed for PM to drop out?
I do it a little bit different but love seeing other ways take parts here there so on.. I was thinking adding ammonium chloride to the suspension might have bonded and dropped it. Loved the video about to watch 2/2 and the longevity of one's equipment is something lost anymore with people glad I'm not alone here's to 8 more years on that vac. Awesome like number 777.
I have a couple buckets of converter shot/stuff. I think now I will just take it in for scrap and enjoy this. Thanks as always bud. You are most certainly a chemist my friend. After getting all the zinc and chemicals, power etc did you get any profit at all. Amazing amount of work bud.
You would be wise to sell the converter stuff rather than try to extract the metals. It's too dangerous and the amount of metal won't begin to cover the cost of doing it. However, the profit that I gained, while not in dollars, is incalculable. The personal triumph of being able to finally pull this off was indescribably exhilarating. Having the only video on the entire planet that demonstrates the process is, well, quite glorious! But, as General George Patton once said, "All glory is fleeting."
I just want to say I have become a fan of your videos, they are the most informative videos on purifying metals around and I find them interesting while most other videos on this subject is boring. I always share your videos on my Facebook page in hopes they will go viral, this is about the only way I am able to help support you at this time.
I thank you for doing that. I've been trying for viral but can't get the hang of it. I guess refining is too specialized, only a small percent are interested.
Congrats Brother,, I wish I would’ve known you were doing this process this soon,, I would have sent you a couple of converter substrates that I was going to process,, I’ve been putting it off waiting for more material to add to it,, after 3 years I’ve decided they need to go, I don’t have time to mess with them,, you can PM me on the forum if you want them,, my name is almost the same on the forum GREAT INFORMATIVE VIDEO
I have always wondered how they exsracted the platinum from the catalytic converters! Good to know, but it seems to me that it is more trouble, then it is actually worth. There are the pros and cons in every situation. All though There has been so many accidental discoveries from these types of experiments. I love watching your videos they are very informative, intelligent and thorough! Thank you for sharing the inside of your brain with us!
It's probably done differently with a big refiner. I did this at the hobby level just to make the video and gain the experience. To the enthusiast it's well worth it. To those who are thinking of doing it to make profit from the metals, probably not. Too much risk for the casual back-yard refiner.
Its well worth the risk, buying old cars and stripping the cat is the way to go, ur problem is ur costs depend directly on the platinum output, strip ur old car and sell spares, ul make more money and have a bigger refinery
Guys and girls be careful taking them cats apart they have a asbestos lining in them with can be harmful when cutting into the cat wear proper safety equipment when processing, mesothelioma is no laughing matter
Well I’m glad you went ahead and changed my mind on thinking this might be easy. I’ll stick to just selling them for scrap. Thanks All the stuff you gotta buy looks like it cancels out your profit.
Platinum on the roadside ?breathing in that shit everyday asbestos also from brakes ....we do a great job of poisoning ourselves lol I wonder what else is out there?Nuclear waste?😭😄😂😂😂😭😄😄😄😞
I don't know if anyone has mentioned this, but a simple way to tell if the converter has not been processed and has intact catalyst is to aim a propane torch onto it; if it incandesces, it is intact, and will even burn the propane flamelessly.
I watched a young man in his 20's doing a video on how to recover palladium from catalytic converters, man that kid had a nasty mess. He did everything messy and backwards, he did zinc at the end and just didn't know anything at all about what he was doing. I'm super happy you're here, because if I followed that guy's method of madness, man it would be bad :(.
Palladium is not as bad a platinum, but both are highly toxic in solution. Get it on your skin and the rash could take months or years to appear. Platinosis.
Best video I have seen in recovering Pt from Cat converter. Couple of question -1. You use sodium carbonate to reduce the acidity of the solution. Can I use calcium carbonate too? 2. How will you know that the all platinum were leached from the cat using HCL and bleach? Looking forward to your response. I hope you will do video in recovering Pt from metallic cat.
I think calcium carbonate is ok to neutralize, but I've never used it so not 100% certain. How to know when all the platinum is leached? Not possible, you simply can't get it all. The best case is to leach for about a month, then harvest the liquid.
Hey bud, I love watching your extraction processes, but I’ve got to tell, you I was more than a little bummed out that you didn't do the beads separate and compare to see what the differential was between the substrate and the beads! keep up the good work, your inspiring me to return to the process...... Peace brother>>>
I would have used a shot of Sulfuric Acid to take care of any Lead. Back in the day the ignorant poisoned their Catalytic Converters by running Tetraethyl Leaded Gas through their cars when they still sold that. I know that nozzle sizes were were varied to prevent this at the Gas pumps. But I learned that I do not want Platinum salt poisoning by watching this video. I was unaware about the toxicity of Platinum Salts.. Great video as usual.
I wonder how they leach the catalytic converters before selling them to you, without causing noticeable damage to the steel shell. I would think that would have dissolved too or at least been noticeably damaged.
Hi Sreetips - I started putting up my lab ( at the backyard) with simple but effective hood. I'm also gathering chemical supplies - and most of these are low grade HCL and bleach. I saw that you used sodium chlorate to increase the reaction . Its difficult to find sodium chlorate here in my country. I'm planning to use calcium hypochorite (50%), is this effective too? Last question: In your video, I seldom see that you stir the solution inside the bucket ( maybe you did) will it be okay to fully enclosed the bucket and just leave small opening to be able to add the bleach (or calcium hypochlorite)? THis is to avoid more exposure in chlorine gas - I will just open the bucket after 2 weeks and its ready to drop the pt. Any recommendations? Sorry for to many questions. Thank you in advance.
I've not used calcium hypochlorite so I don't know if it will work. I used sodium chlorate to speed it up. But just adding bleach and waiting longer should work. If bleach is poured through a small opening then it may shoot a jet of chlorine gas when bleach is added. I recommend that you don't try this experiment without the proper safety equipment because it is too dangerous.
Actually cleaning the stock pot out and believe to have tons of pgm from my dropped gold solution...after I drop gold again I will add it to my other pd solution and get some dmg😉 awesome video!!
sreetips as I watched this video I filtered my stock pot 😁 took me several hours to filter about 3 gallons of solution....well worth it got about 5 g....
Wearing chemical PPE (personal protective equipment) would it be more effective to drain off the liquid into a clean bucket each day, add the bleach, gently mix, then pour the solution back over the catalytic converter material?
Don't get me wrong, it was informative for most. Nitric acid would have been the way to go, but you opted for the more difficult route. We are appreciative of the work you put in. That being said you restate the same thing over and over again until the point I'm screaming at my phone. Once or twice is OK -- four to five is just too much. FYI, I did some math with spot prices today. Below are my results. Keep in mind these are just estimates. HCl 5ga@$8: $40 NH4Cl 1lb@$10: $10 40% H2O2:$10: $10 NH3/NaClO/H2O/Clorine tabs/Filter paper $10 Catalytic Beads (said a couple hundred): $200 Zn (didn't show us how much was used): $100 Total Cost: $370 Pt p/g: $25.60x4=$102.40 Pd p/g: $31.66x10(*)=$316.60 Total Net: $419 (*): you yielded 6g Pd with the additional vial you added to the reaction. You claimed another 6 was in the buckets. 10 grams is my estimate. This took you at least a week not including time it took you to film it and you (would have) made roughly $50 (not including whatever you spent on the catalytic converters). You said you are selling that at a third of the price on Ebay so you lost about $250 after acetylene and oxygen and electricity and cleaning supplies/neutralizer (YMMV in any given location). Thanks for taking the time and money to do this. Just try to stop repeating yourself.
I've tried nitric in the past. Chlorine leach is much cheaper and much more effective at removing the PGMs from the ceramic substrate. Hopefully, after watching this video (the only video series of its kind on the entire internet) those who want to "make money" refining cats will become discouraged. You can't make money refining the platinum group metals from automotive cats. It's just not going to happen. It's too dangerous for the backyard hobbyist. And the yields are too low to cover expenses. That is the whole point of this video series. Sorry for the repetitiveness. Most videos on this subject are vague, leave out critical details, or just show part of the process. I try to include as much detail as possible for the benefit of those who want to know, and see, the entire process.
Spanky, I don't track expenses for each experiment. But as you can see from the video, this is far too dangerous and complex for someone trying to extract a few grams of metal from these cats in their backyard. It's best left to the pros who have all the proper safety equipment. I only did it so that I could make the video. I'll probably never to it again.
I added some more dilute HCl and spoon full of sodium chlorate every week or so. They are still leaching. I'll get the liquid some day and slowly add it to my stock pot. I don't think it's possible to get all the metal. Diminishing returns sets in very quickly.
You are a genius and legend. I wish. I could learn some of the stuff you know and I would love to have a lab like that. I buy storage units for a living and finds tons of items that have precious metals storage in them and all ends up free to me.

My life is fleeting. It’s been a wonderful ride.
Dang bro but I guess Father Time is undefeated, your videos are amazing and will stand the test of time
Definitely great information buddy! Thanks for sharing! Go Navy!

SreeTips, Thank you so much for the expertise of Your classes.
William, I'm glad that you liked the video. Thank you
I just want to say I have become a fan of your videos, they are the most informative videos on purifying metals around and I find them interesting while most other videos on this subject is boring. I always share your videos on my Facebook page in hopes they will go viral, this is about the only way I am able to help support you at this time.
I thank you for doing that. I've been trying for viral but can't get the hang of it. I guess refining is too specialized, only a small percent are interested.
Well your graphic warning convinced me to never try this. Thanks, really thanks. Lol
Ever heard of a gas mask
Congrats Brother,, I wish I would’ve known you were doing this process this soon,, I would have sent you a couple of converter substrates that I was going to process,, I’ve been putting it off waiting for more material to add to it,, after 3 years I’ve decided they need to go, I don’t have time to mess with them,, you can PM me on the forum if you want them,, my name is almost the same on the forum GREAT INFORMATIVE VIDEO
I give you a shout, thank you.
OK I'm in
I need d more info......
Wow your very intelligent thanks for sharing and a shout out from Australia knolage is expensive
Thanks for sharing your work !
I'm really fan !
Regards.
notice the baking dishes?..betcha never look at 2nd hand shop kitchen utensils the same way
Cool video bud man that's crazy long process you could just go nugget hunting with me bud :)
The stock market is the BEST way to make a few quick bucks these days.
Sorry to say that I wouldn't wish the stock market on my worst enemy right now.
Good
I have always wondered how they exsracted the platinum from the catalytic converters! Good to know, but it seems to me that it is more trouble, then it is actually worth. There are the pros and cons in every situation. All though There has been so many accidental discoveries from these types of experiments. I love watching your videos they are very informative, intelligent and thorough! Thank you for sharing the inside of your brain with us!
It's probably done differently with a big refiner. I did this at the hobby level just to make the video and gain the experience. To the enthusiast it's well worth it. To those who are thinking of doing it to make profit from the metals, probably not. Too much risk for the casual back-yard refiner.
Its well worth the risk, buying old cars and stripping the cat is the way to go, ur problem is ur costs depend directly on the platinum output, strip ur old car and sell spares, ul make more money and have a bigger refinery
Refining platinum group metals is for the pros. There is too much danger. Selling the cats just like they are is the way to go.
I've seen them run catalytic converters through a solution at the junkyard in New Mexico. They let them sit in big 55 gallon drums.
You should have ground everything first in a ball mill maybe
That should prevent the cores from not reacting equally and lowering volume of hydrochloric acid .
so when we do stuff how to we take proper care of waste ?
Waste treatment... I'll have to make a separate video. We use chemistry to get out the toxic metals and make it safe for disposal.
that would be grate I don't think anyone wants to heart the earth .
Excellent video! Thanks for sharing!
I’ve been looking for this video. Thank you.
Tyler, the platinum refining video is uploading as I write.
Why don't you buy the catalytic converters directly from your nearest car scrapping yard? It beats being ripped off on the Ebay...
Excellent advice, Thank you.
Scrap yard remove the cats right away apon receiving junked cars
Yeah I saw just universal catalytic those works like $10 each
Guys and girls be careful taking them cats apart they have a asbestos lining in them with can be harmful when cutting into the cat wear proper safety equipment when processing, mesothelioma is no laughing matter
If you or a loved one has.....
Good srretips!
Beware of platinosis
Waiting for part 2.
awesome video as always. A big thank for your knowledge sharingss. :) ;)
He has so much carcinogens and asbestos in that room to kill city block. No way would I be in that room. 🏃🏃🏃🏃
The flux capacitor!
Well I’m glad you went ahead and changed my mind on thinking this might be easy. I’ll stick to just selling them for scrap. Thanks
All the stuff you gotta buy looks like it cancels out your profit.
Wise decision.
You’re like a mad scientist of refining
Platinum on the roadside ?breathing in that shit everyday asbestos also from brakes ....we do a great job of poisoning ourselves lol I wonder what else is out there?Nuclear waste?😭😄😂😂😂😭😄😄😄😞
Lead dioxide from years ago, manganese from now, benzene, so yeah a lot of crap.
As always u r great sir I salute u dear
I watched Cody from Cody's lab.
He did this but we'll anyway I am happy to watch this.
I don't know if anyone has mentioned this, but a simple way to tell if the converter has not been processed and has intact catalyst is to aim a propane torch onto it; if it incandesces, it is intact, and will even burn the propane flamelessly.
Great great great...I love this.Not that i intend to do this, bud i love the science.
Thanks for charing...
It is not Platinum or Palladium that has the most value in catalytic converters, it is Rhodium. It takes very high temperatures to recover it.
I watched a young man in his 20's doing a video on how to recover palladium from catalytic converters, man that kid had a nasty mess. He did everything messy and backwards, he did zinc at the end and just didn't know anything at all about what he was doing. I'm super happy you're here, because if I followed that guy's method of madness, man it would be bad :(.
Palladium is not as bad a platinum, but both are highly toxic in solution. Get it on your skin and the rash could take months or years to appear. Platinosis.
I have no interest in doing this myself but your videos ate so interesting to watch though!!
Awesome work sir! Thank you for taking the time to make this video
I still can't believe that I was able to pull it off.
@@sreetips Aren't you doing this on a regular basis?
Best video I have seen in recovering Pt from Cat converter. Couple of question -1. You use sodium carbonate to reduce the acidity of the solution. Can I use calcium carbonate too? 2. How will you know that the all platinum were leached from the cat using HCL and bleach? Looking forward to your response. I hope you will do video in recovering Pt from metallic cat.
I think calcium carbonate is ok to neutralize, but I've never used it so not 100% certain. How to know when all the platinum is leached? Not possible, you simply can't get it all. The best case is to leach for about a month, then harvest the liquid.
Thank you for the response. Appreciate it
3.6K+👍's up sreetips thanks for sharing
Great to know I'm never going to even attempt that even if I can.
It does give me a therozing question on some other subjects.
.....Thanks
He’s a good looking chemistry teacher 😂
Love your videos !!! I'm such a nerd 🤓 but .... I'm happy 😊
Hey
bud, I love watching your extraction processes, but I’ve got to
tell, you I was more than a little bummed out that you didn't do the beads
separate and compare to see what the differential was between the substrate and the beads! keep up the good work, your inspiring me to return to the process...... Peace brother>>>
Sorry. I had those sitting around for years so I wanted to get them processed and get them moving.
Sir I am in awe of you absolutely amazing
Holy amount of work, im fine watching this on YT. Never wanna try this at home, not even a small scale. very intersting .
Muchas gracias por comunicarse conmigo y gracias, sorry I'm not speek very much English, bad thanks for your time
Kev you are the guy to go to to learn everything
Wonderful video very very nice awesome thank you sir
Love the video. Very entertaining.
I would have used a shot of Sulfuric Acid to take care of any Lead.
Back in the day the ignorant poisoned their Catalytic Converters by running Tetraethyl Leaded Gas through their cars when they still sold that. I know that nozzle sizes were were varied to prevent this at the Gas pumps.
But I learned that I do not want Platinum salt poisoning by watching this video. I was unaware about the toxicity of Platinum Salts..
Great video as usual.
I'll have to remember to do that when I try to refine it in part 2 of 2
Thanks for posting this video I loved it.
You're welcome Red
That was awesome. Thank you👍
I wonder how they leach the catalytic converters before selling them to you, without causing noticeable damage to the steel shell. I would think that would have dissolved too or at least been noticeably damaged.
Great work ! Thanks so much 😃
Hi Sreetips - I started putting up my lab ( at the backyard) with simple but effective hood. I'm also gathering chemical supplies - and most of these are low grade HCL and bleach. I saw that you used sodium chlorate to increase the reaction . Its difficult to find sodium chlorate here in my country. I'm planning to use calcium hypochorite (50%), is this effective too?
Last question: In your video, I seldom see that you stir the solution inside the bucket ( maybe you did) will it be okay to fully enclosed the bucket and just leave small opening to be able to add the bleach (or calcium hypochlorite)? THis is to avoid more exposure in chlorine gas - I will just open the bucket after 2 weeks and its ready to drop the pt. Any recommendations? Sorry for to many questions. Thank you in advance.
I've not used calcium hypochlorite so I don't know if it will work. I used sodium chlorate to speed it up. But just adding bleach and waiting longer should work. If bleach is poured through a small opening then it may shoot a jet of chlorine gas when bleach is added. I recommend that you don't try this experiment without the proper safety equipment because it is too dangerous.
Thank you again for the quick response. Yes, I understand the danger and I'm preparing necessary/proper equipment to do the experiment safely.
Actually cleaning the stock pot out and believe to have tons of pgm from my dropped gold solution...after I drop gold again I will add it to my other pd solution and get some dmg😉 awesome video!!
After part 2of2 is done my next video is my stock pot. Thanks SONNY.
sreetips as I watched this video I filtered my stock pot 😁 took me several hours to filter about 3 gallons of solution....well worth it got about 5 g....
Great detailed video, thanks
Thank you for video demonstration.
Wearing chemical PPE (personal protective equipment) would it be more effective to drain off the liquid into a clean bucket each day, add the bleach, gently mix, then pour the solution back over the catalytic converter material?
Don't get me wrong, it was informative for most. Nitric acid would have been the way to go, but you opted for the more difficult route. We are appreciative of the work you put in. That being said you restate the same thing over and over again until the point I'm screaming at my phone. Once or twice is OK -- four to five is just too much. FYI, I did some math with spot prices today. Below are my results. Keep in mind these are just estimates.
HCl 5ga@$8: $40
NH4Cl 1lb@$10: $10
40% H2O2:$10: $10
NH3/NaClO/H2O/Clorine tabs/Filter paper $10
Catalytic Beads (said a couple hundred): $200
Zn (didn't show us how much was used): $100
Total Cost: $370
Pt p/g: $25.60x4=$102.40
Pd p/g: $31.66x10(*)=$316.60
Total Net: $419
(*): you yielded 6g Pd with the additional vial you added to the reaction. You claimed another 6 was in the buckets. 10 grams is my estimate.
This took you at least a week not including time it took you to film it and you (would have) made roughly $50 (not including whatever you spent on the catalytic converters). You said you are selling that at a third of the price on Ebay so you lost about $250 after acetylene and oxygen and electricity and cleaning supplies/neutralizer (YMMV in any given location). Thanks for taking the time and money to do this. Just try to stop repeating yourself.
I've tried nitric in the past. Chlorine leach is much cheaper and much more effective at removing the PGMs from the ceramic substrate. Hopefully, after watching this video (the only video series of its kind on the entire internet) those who want to "make money" refining cats will become discouraged. You can't make money refining the platinum group metals from automotive cats. It's just not going to happen. It's too dangerous for the backyard hobbyist. And the yields are too low to cover expenses. That is the whole point of this video series. Sorry for the repetitiveness. Most videos on this subject are vague, leave out critical details, or just show part of the process. I try to include as much detail as possible for the benefit of those who want to know, and see, the entire process.
sreetips exactly the response that I was looking for. Yes the nitric can be more expensive, but the time it requires saves you in the long run.
Cameron J so if you know any short cut on the process maybe you can do a video and share it with everyone.
I love science so these videos are wonderful. One think I'd love to know is in total what is your total cost compared to your sales of the metals.
Spanky, I don't track expenses for each experiment. But as you can see from the video, this is far too dangerous and complex for someone trying to extract a few grams of metal from these cats in their backyard. It's best left to the pros who have all the proper safety equipment. I only did it so that I could make the video. I'll probably never to it again.
Have always loved your videos friend. Will you do other multiple leaches of the catalyst materials or do you think you got most of the PMs.
I added some more dilute HCl and spoon full of sodium chlorate every week or so. They are still leaching. I'll get the liquid some day and slowly add it to my stock pot. I don't think it's possible to get all the metal. Diminishing returns sets in very quickly.
I'm surprised you did not choose to siphon that toxic orange solution from vessel to vessel... seems like it would be safer? Love your videos!
Did you try RE hydrating with a little HCL?
very good videos of your work
You are a genius and legend. I wish. I could learn some of the stuff you know and I would love to have a lab like that. I buy storage units for a living and finds tons of items that have precious metals storage in them and all ends up free to me.
Nice! I wish I could get metals for free.
Well free but I have to work hard hauling and processing the stuff. Watch my latest video about storage units and let me know what you think.
How do I get in on those
A lot of hard work, it's all good.
When I was in the Navy. We called it P.M.S. preventive maintenance and servicing.
I remember it well. Ever hear of “gun decking?”
@@sreetips Gun decking no I found scuttlebutt to be a funny word. Also sound powered phones are cool.
Gun deck is when some one marks a PMS check as complete, but never actually did the check.
@@sreetips Sounds shady and lazy.
Agree - none of my guys did it. I did spot checks. You can tell right away if they gun decked the check.
