Thanks Sreetips! I'm doing a thesis on "Our world recovery/reuse" recycling. This video has helped me very much in what some call a useless attempt or our children's paradox on wanton waste without responsibility. We need and should be more like our great ancestors and take just what we need and give back a little. Instead of just frivolous, selfish waste.
You're welcome! That's why I made the video. To show you that it's just not worth it. Too much time, trouble and danger for so little pay. I hope I've done my part to discourage those who believe that this can be done to make money. Quite clearly - it can't. Glad I could help.
I greatly appreciate how clean and efficient you are with your materials, processing, and transferring. It is very satisfying. I hate it when chemists are messy.
Great video. Here in Australia, a company buy 44 gallon of the inside of the cats. They crush it up, Weigh it and test a sample and give u a price. They ship it to china. I couldn't give u a guessement, i never done it. I know some cats r worth a lot. My son's car needed cats. Mechanic said only needed one. I looked into original which were over $1000. Second-hand from the wreckers was $700. I could got aftermarket ones, but was told they might throw codes. I found guy parting out cars. He sold them for $200 each and told to sell the old ones for no less $150 each. Which i got, a lot eager people wanting to buy them
Streetips thank you for your presentation is very didactic and I for one appreciate all the work and explanations you give us , may the Lord keep blessing you and give you and your family health and protection from any exposure to the gases and chemical reactions, keep up the good work.
I thank the Lord, on my knees, every morning, for what has been granted to me. May I utilize it in a worthy way and not squander my life or my talents.
Wow!!! this is amazing! reading about science can be a bit boring, however watching science being done is just fantastic! I take my hat off to you. thank you for that journey and experience.
Man this channel is my favorite channel to binge. I wish we had access to videos like this when I was younger. I would probably be in a different field of work
What I realized in many of your videos: You tend to use sodium carbonate for neutralization often. In my studies at the uni we hardly ever used it coz it increses the amount of unremovable salts. The results are forming precipitates of unwanted substances. In this series you finally managed to use ammonia instead which is the best option - because as you have demonstrated it - you can remove ammonium chloride easily by heating it out. Well done!
47:24 a cheap method we use in chemistry for drying out chemicals is to place that petri in a bag, then put a plastic cup with a scoop or two of NaOH in it next to the petri dish in the bag, and seal the bag. The NaOH will pull all the water from the petri by desiccating the air in the bag. Then just replace the NaOH with fresh pellets when it gets too wet unless your compound is dry. NaOH is strongly hydrophilic.
You could probably use pool "shock" powder instead of the chlorine tablets. Double check with a chemist if possible to make sure or experiment with a small amount if possible. I cleaned pools for years and consistently substituted powder shock spread across the top of the water to fix chlorine deficiencies much faster.
As always your videos are extremely educational and incredibly inspirational. I've finally gotten around to working with some of the white gold I've saved up. Has me scratching my head though. Testing on individual pieces to gain knowledge before I lump it all together. Two 14K rings for a total of 7.4gm fully dissolved in AR without inquarting. Zero silver chloride formed. Solution was clear and started out orange then transitioned to a very dark red with a slight brown tint. Got 4.25gm of gold after the SMB drop. The leftover solution was a washed out orange/mustard yellow. Stannous test before SMB showed a nice purple and slight brown. Very dark, quick brown after SMB and it looks very much like a false positive. But if not I can't figure out what the other 3.15gm was so I'm stuck figuring out how to work with it and get it out of solution. My best idea is to cement with zinc but that still won't tell me what it was. Since no silver chloride formed in the AR I have to think maybe palladium, but again...not sure and I'm just guessing. These were old worn out rings and any rhodium plating was virtually gone so I'm doubting that was the cause of the deep red. I'm stumped here.
Some older white golds were alloyed with palladium. If you got a brown stain then that may be what it is. Less concentrated solutions of Pd produce a green stain with stannous. If it were me, I would add it to my stock pot and let the PMs cement out on copper and accumulate. trying to recover and refine small amounts of platinum group metals is difficult.
Wow! Thank goodness I was able to see this amazing video BEFORE I tried it myself......you would need to be a full on Chemist and have a full lab to be able to do this safely. I can’t see any way to do this profitably.....
excellent. It's the reason I made the video. It's too difficult and too dangerous to try. Even for an experienced gold and silver refiner. I'll probably never do it again. But at least I gained the experience from doing it this one time.
Very educational!!. But the the process... I'll go buy my platinum from the store. Lol. Love the videos. Watched both of them!!!! Titanium should be next!!
I absolutely loved the 2 video series, and I really appreciate the reply to me on your Part 1 of 2 video. I liked and subscribed and look forward to your next video.
Just watched both videos back to back, brilliant! Jeez I'm sure if you tried to buy all those chemicals here in UK you'd have an anti-terrorist unit camped on your doorstep disguised as trees and the SAS ready to storm your house as soon as the last package was delivered! LOL Excellent videos Sreetips!
I have a few cats and I was thinking about it but I'm glad I saw this first. To me, this is complicated, dangerous, tedious, expensive, a lot of waste to deal with, and plenty of opportunities to either screw up the process and/or get sick and/or killed. I'll sell the cats to the scrap dealer and use those to get some scrap sterling silver. Growing silver crystal is not to be disrespected either but it looks attainable to me and the crystal is so awesome looking.
Probably the most in depth and precise videos I've watched on the process. Nice job. BUT.. no matter how much you clean your propane torch tip, it wont turn it into an oxy-acetylene cutting torch!! just sayin'... Besides that, a 5 star video! I was amazed with the amount of palladium you extracted! I thought it would be less than the platinum, but wow. Current spot on that is at $1,320.00 per oz.
Great video! Thank you! If you could point out tap or distilled water (at the beginning of video 1 you added water from a bucket with the HCl leaching process ). Where I live (Eastern Washington St.) the water has high concentration of calcium carbonate from our glacial aquifer--water spots on everything and 10 miles north of here they have iron sulfide in the ground water and as I understand parts of upper NY St. have lithium in the water... Many catalytic converters from the 1970's and n1980's were contaminated by the use of leaded gasoline in unleaded only autos. Also worn engines that burned oil from that era often contaminated the cats with zinc additives from the consumption of oil. Modern motor oil and auto manufacturers no longer use metals (zinc) in engine oil since modern autos have roller lifters/camshafts that no longer require the added benefit molabnanim /zinc/ manganese etc as flat lifter/cams previously did.. Because of metal contamination of emission systems and exhaust emissions, auto manufacturers moved toward expensive roller lifter/cams. Auto manufactures began phasing out the need for zinc (metals) and sulfur (and other chemical additives) in engine oil from the mid 1980 to the mid 1990s in order to meet increasing EPA regulations/standards. Hope this helps to figure out 3 potential sources of the unknown filtered crud. Thanks again! (I realize - probably lecturing to the professor)
Oh man what a nice vid and you certainly did your preparations there... bit of a bummer you put the PtCl4 out of the way but hey I like suprises... I'd really like to see you upgrading your fumehood. Also vacuumfiltration in a twice as big fumehood and a huge sink untherneat. maybe a glovebox would be best. I think you are tempting Murphy here. pity you put 2 batches of PtCl4 together... I was interested in the yield of 1 catalytic unit. but I ain't gonnah do that at home :D
When I get the Pt from my stock pot I'm going to go all in with all the Pt that I've harvested so far. Either bromate hydrolysis or formic acid reduction. Watch for the vid!
If you were to ask if I would be willing to spend 2 1/2 hours to watch you do this, over 2 1/2 hours ago, I definitely would’ve said no. 40 minutes into part one I pressed on the screen only to realize that I was only halfway into that video(For some reason I didn’t check the length of the video before started, probably because I had no idea it would’ve been that long). That was too much time invested into that video to not watch the rest of it, and thus too much time to not watch part two, and so here I am finished with both videos. Thanks for sharing that, and although i did find it interesting to watch the process, I would not do it again, not for that long of time. Aloha
Awesome another awesome video I'd like the way you explain everything perfectly as if You were talking to somebody that Has ADD and that's pretty cool because there's a lot of People that has that problem and Your name of the channel is perfect for about you present yourself street talk not smart Talk were nobody knows what you're saying... So thank you for your video and one day I hope I can do same thing But I would wanna Do everything the right way , Environmentally friendly exactly how you do it... Keep being awesome my friend street tips the perfect name for you .... Thank you for your service and have a great day sir
Judith, I watched this video all the way through again the other day. As I'm watching I'm thinking to myself, how in the heck did I pull this off. There is no recipe. I just built on my knowledge and experience and forged ahead leaning as I go. But I'd remiss if I didn't give some credit to the goldrefiningforum.com
@@sreetips I was wondering if you ever buy palladium through the mail if the seller promise to give you a good deal? I will be having some palladium in the near future [that won't be as refined as you have done on your video] because i don't know that i have the equipment or skills to get that done but i would want to see it go to the best possible person all the same. My email is gs853640@gmail.com if you are interested in buying or even if you are possibly interested in collaborating on the refining process of palladium.
Hey, I'm not sure if it was this video, but in one of your videos I saw you using a _huge_ glass pipette, it was the size of a turkey baster, if not larger. Where did you get that from? Does it have the brand/size listed on it? Sorry for posting this on a random video of yours, I just remember seeing it in one of them and I'm skipping through your videos and I can't find which one has it. Thanks again.
Dear Sreetips, in this video series you're sometimes using the vacuum pump to filter the solutions and sometimes just a regular filtration. What's the reason behind the alternation between methods, please? [Thank you, by the way, for being a big part of my 2020 youtube experience -- I wish you and Mrs Sreetips a blessed Christmas and a good and healthy 2021. Best regards, Stefan]
that 12 grams of Palladium is worth about $550.00. wonder how much Platinum you got out? Also, I cannot believe that Palladium @ $45.25/gram is worth more than Platinum @ $29.50/gram.
I've been a subscriber for quite some time now and I want to thank you for sharing your knowledge with us. I have questions about recovering gold from a potassium cyanide solution do you think you can help
usually if cameras (both video and still) are set for tungsten, it can give many colors a blue-ish-looking appearance (as you probably already know, yellow and blue make green).
Thank you for the video. Very informative. Can you tell me what the gas is that comes off my scrap gold/copper in a hydrochloric and nitric acid mix when it fumes. Also could you tell me what the gas is that comes off my acid once I remove the nitric acid from the solution with urea and then add my SMB. When I add the SMB is when I get a very nasty gas. Wondering what these gasses are...Chlorine/NoX maybe?
Dear Mr. Sreetips, You are the greatest! Where did you get your Glass HCL Gas Generator valve? I would like to automate the valve but first I will try your method. thank you for being so safe.
Loved the video. As usual instructive and entertaining. I was just wondering.... what sort of metals would be hiding in that pale transparent yellow liquid underneath that creamy yellow palladium? Thanks for sharing the video, and nice work :)
That will probably have some palladium and maybe a trace of Pt. I tried to rinse that yellow precip with cold distilled water until the rinse water was colorless.
When you assembled the chlorine gas apparatus the powder became wet somehow. What did you add to the the dry chlorine powder and how much? I realize this was 2 years ago but I'm hoping you remember. Thanks mate! Nice work!!
Hello StreeTtips author. Why you only end up with 6 grams of pure palladium? I noticed in the beginning you have almost 20 grams of black pgm powders. Did some of it get lost in the process? Or did you only refine a portion of the pgm powder solution?
Very Nice melt! Beautiful Palladium Button!! I have a question, at the 51 to 52 minute mark you took the torch to the palladium sponge because the palladium wasn't getting hot enough on the top. There was just a little that didn't get hot enough. Would a lid over the corning wear dish (to circulate the heat) be a another way to heat the top?? I'm just asking to learn and see what your opinion is if that could be another way to get it dry?? Thank you Sreetips!!!
It needed more heat under the dish. I should have put it on an iron ring stand and applied a low flame directly to the bottom of the fused Quartz dish. But be aware, heating the salt too fast can cause it to vaporize and cause loss of metal.
Here is the video that I was asking about the other day. I am still wondering what is the ROI and what would happen to the Platinum, who would buy that and why, would it end up going back into a Catalytic Converter? So basically you are doing the recycling?
Hey I've stumbled across your video's. Love the content. Small suggestion in the description part of your videos where you add websites you can add your link to your eBay store's. It makes it easier to click then to play the video back to list to the name of your store and write it down. Lol....
I’ve sent material in for refining twice.Both batches took around 12 years to accumulate.The first company’s yield was 33.1 ounces au the other company’s yield 4.1 ounces au even though the materials submitted were twice as heavy.I was robbed !! But still I’m not ready to attempt the process.I will definitely use the first company next time I have a batch.
sounds like you got a drag strip in the background there buddy.. the only good bafel is used to modulate weight transfer in the fuel tank.. make peace not war, live long and prosper.. Liam
We used to have a half mile dirt track here. Met Dale Earnhardt there one Friday night. He was near the ticket counter signing autographs. The Summerville Speedway. It’s gone now, they built a subdivision there where it used to be, about thirty years ago back in the 90s
I've watched part 1 and 2 I don't know how many times. I love what you do Sir. I was wondering. Do you do this just for you or do you also do it for others for a percentage of whats recovered? Either way, I think you're great. Hope you and your family are well.
@@sreetips I think I have a problem. During the initial filtering processes, where you're removing any solids from the solution during the 5gl bucket process is where I'm at. My problem is. I was almost done to the point of having a clear liquid, BUT on the last filtering I did it in the sunlight. The solution started to produce a black spongy looking material! Freaked me out. Can the sun push the PGM's back out of solution? Or do I have another metal being produced because of the sunlight (being pushed out of solution)? Can it possible be silver (which I don't understand how it would be there). I just don't know?? What can the sun in a white 5gl bucket push out of solution?
@@sreetips Everything was going smooth with no problems at all. Until I put a white 5gl bucket of partial solution in the sun. First it started out a light grey looking see threw gel floating thru out the solution then slowly it got darker until it was a black looking spongy material. My first thought was, is the sun pushing out my PGM's? (but I couldn't wrap my mind around that). Then I thought. Silver? From where i got my original material, I wouldn't think there was "silver" in it. So I thought of you and thought I'd pick your brain. Thank you for your reply. I hope you and your family are having a great day Sir!
Congratulations for the video. I didnt understand well why did you re-dissolve the Paladium salt in NH4OH after this precipitation process with Cl2 gas?
I’d have to check. After precipitating the brick red Pd salt the next step is to dissolve it in ammonia and filter. Then re-acidify with hydrochloric acid to form the beautiful canary yellow palladium salt. Then calcine to burn it to a fine gray ash. Put it in a crucible and melt into a button
Hey sreetip firstly thankyou for giving your time and effort by puting this knowledge out to the public. I have a question regarding the Rhodium content, does it precipitate like platinum using ammonium chloride or is there another reagent one must use to separate it from the rest of the pgms. Thanks again, and i would be greatful if any of you guys can refer me to documentation on the proces of precipitating rhodium.
We use boric acid dissolved in denatured alcohol as a pre-treatment when soldering gold and silver jewelry. It acts as a flux to help the gold solder flow into the joint being soldered.
Hi, Sir. Thank you very much for sharing your valuable experience. What is next procedure for Pt. which is still in small container? Please share a link if you have made any video about this. Thanks alot.
I have Pt salts, like you see in this small container, from previous videos. When I can get to it I'll demonstrate how they get it processed. It will be coming out soon as I get the time to produce the video. Thank you for your interest.
@@sreetips Hello Sir, Thanks for reply to me .I have become very serious for recovery of palladium from catalytic converter after watching your videos. First of all I have started to make feasibility. Raw material (without iron body) is available @ 47 usd per Kg. I just want to know that after buying material at this rate, will it be profitable or not after paying all further expenses? can you please share information regarding cost? Thanks
Roy, the ammonium chloride infused palladium solution must be chlorine sparked to create the ammonia soluble Pd2 salt. Only then will the ammonia dissolve the Pd2 salt.
Could you have put the ceramic substrate from the last video into a ball mill to crush it all up? You would have more surface area for the acid to leach as much PGMs out. Or would that not make a difference?
Hi Nice Video. How about the Rhodium? What if the catalytic that you processed has Rhodium on it. Will it be precipitated together with the platinum or with palladium? How will you recover the Rhodium? thanks
Hello Dear Sreetips, you are using H2O2 with HCl to dissolve PGMs displaced with Zinc. If I use AR instead to dissolve them trying to have as little as possible excess of HNO3 in solution, will all the reactions shown in your video go as in hydrogen peroxide + muriatic acid method?
Thanks a lot buddy, so useful educational video. Well, could this method be used for getting some money (as a own business)? As I checked that out, the price of palladium, the amount of palladium you got, and the cost of the mufflers and chemicals you used make it nonprofitable business. Am I right my friend? I need your advice.
You are correct. I only did this to demonstrate the process and make the video. Trying to do this as a business would be difficult. It's dangerous to health. it would be like designing your own computer and trying to compete with IBM. They would crush you.
Perhaps this pink compound may be rhodium chloride, if it is mixed with sodium bisulphate in a liquid solution of distilled water in stoichiometric ratio 3 moles of NaHSO4 to 2 moles of Rh which it believes to be present at a temperature of 450ºC to 500ºC has diluted formation of Rhodium Sulfate, then adding Ammonium Chloride to form a rhodium-containing complex and finally set up an electrocatalysis process to reduce the metal by hydrogenation at 1000ºC, perhaps rhodium in solution can self function as a catalyst in the presence of excess hydrogen and precipitate into its lowest Nox, being ready for casting after drying on quartz watch glass.
Hi Professor. thanks for the video. I see all your videos. you are the best. But I have a question. If I have silver in soluction. How can I recover the silver(with Salt??) and after recover the others metals?
I don't use salt. Instead I add clean copper and cement the metals out of solution. Any metal below copper in the reactivity series will come out of solution on the copper. Any metal above copper will not cement and stay in solution. The silver comes down first, then the gold, if any, and platinum group metals. These metals will appear as a fine black powder on the copper after all the silver has dropped.
ok professor. but ... them... i will put everything in nitric acid. how can i separete the silver from palladium? silver, palladium and platine will go to soluction. gold remains in a pouder staff. am i correct?
Thanks again . I'm waiting for your stock-pot video , before I start processing , I want to find how I can keep any waste to a min. , also recover any value . To me it seems , I do electronics repair - that has also become scrapping of electronics . That just off the top of my head , trying to get precious metals - maybe just a percent or 2 generally speaking in all circuit boards , there is probably around 30% copper , which is a large part of what I started getting cash for . So with all the different values , even capacitors etc. , so maybe 6 to 8 or even 10+ stashes of different of goodies to cash-in on ;) For me I start with gold mining [ underwater suction dredging ] methods gravity , high heat burn off for chips etc. , then chemicals lastly . All down to as little waste etc. to deal with .
Ok thanks again . From yrs. ago , reading / hearing Buckminster Fuller say something like , there is no waste , all waste is someones resource . So reducing my waste to someones resource ;)
