This series of videos is incredible! Absolutely a good time! And then the parts where you say" Not sure what that is" or "Don't know what is going on" make it even better. Kinda like we're all in class together! Thank you!

i don't understand why you don't simply pick out the larger zinc pieces? You can rinse them with HCl in a separate container if they have metal plated on them. Might save you on HCl and give you some "dirty zinc" for various purposes that pure zinc might feel wasted on.
I'm assuming it is because it would be difficult to be certain all contaminants other than zinc had been rinsed away. If potentially contaminated zinc was used in another reaction there could be unexpected byproducts best case and worst case an unexpected reaction. I don't know jack so I could be completely wrong but that's what makes most sense to me
Another awesome video - really an impressively difficult process I think extracting palladium or platinum from those filter basket slimes! Great video series! 👍
Great video Sreetips! I haven't seen you do a precious metal refinement in a while and this one is unique all on its' own. It took me a second to realize that grey stuff was foreign material. Decanting off an unwanted material like that had me almost at the edge of my seat 🤣That HCL wash at the end really did the trick though, GJ!
I'm not a chemist but I really enjoy your shows. I'm getting ready to put my truck into aqua regia and I hope it helps with the valve issues. I'll keep you posted.
hey streetips, great series! you could probably save some materials by neutralizing the pH with a base before adding the Zinc in the cementing process so it isn't destroyed by the acid before reacting with the PGMs, and also by roughly measuring stuff closer to the stoichometric amounts, which is about 1g Zn ~ 3ml Muriatic Acid
@@user-mh2tt1su9o I don't think that's the case, we clearly only start seeing precipitate once the zinc can survive the acid. It's a displacement reaction, the chloride prefers sticking to the more reactive metal: PtCl2 + Zn -> Pt + ZnCl2
Rhodium!!!! Could that be rhodium(iii)chloride.[trihydrate]? That red looking precipitate which made a yellowy, pinky red colour when you partially dissolved it in HCl? Don't know but it certainly could be and looks like it. Certainly doesn't look like trash!
Another exciting episode in the anode filter basket refining saga starring Sreetips . Can't wait for the next one . Kinda curious to know how you would go about seperating palladium from platinum .
Dear streetips I know you work very hard on this channel and I check every day to see a new video from your channel I wish you the well-being and health lots of prayers and a happy life
He's got a couple silver harvest videos, and casting bars with it too. He even has one where he compares lye and sugar extraction with electrolytic silver. Cool opal like shine on the bars. But, I have no doubt he'll do more of them.
Could you use powdered zinc or fine shot to speed it up? Could that cause confusion with the precipitated pgms, maybe to be fixed by some sort of strainer?
Been watching for a while, good stuff man. Question, if Silver will cement out on Copper in an acidic solution of Silver...will Gold cement out on Silver in a solution of Chloroauric acid with the Silver going into solution? Or will we end up with Silver Chloride mixed in with our Gold?
Ir (iridium)? is notable for not dissolving in AR not sure about Rh (Rhodium). Did a research grant one time on extracting rare earth metals from ore they're just about as hard as PGM to separate.
Hi Sreetips, another great video.. but I did do a big facepalm at the start of the vid when you added the black powder which you solidified out using zinc (which you got from the nitric acid dissolving vid 1.) To the aqua Regis batch (most recent batch) I think you would have found that the first batch would have been palladium in silver nitrate. As palladium dissolves in nitric acid when silver is present. But platinum does not. (I found this out when I googled does palladium dissolve in nitric acid.) So from what I surmise is you mixed the palladium back in with the platinum, which I would have kept separate and tested with aqua Regis and Standish test separately to see if this is correct. Maybe a thing to try next time. Keep up the great work 😎 👍 looking forward to the next visit as always.
This is the result I got from Google when I typed 'Does palladium dissolve in nitric acid '; Palladium, particularly if alloyed with gold or silver, dissolves in dilute nitric acid. Fine grained palladium is soluble in concentrated nitric acid, concentrated hydrochloric acid or aqua regia. I hope this helps with future projects when separating out the metallic elements. 😎 👍 from this it would suggest it is possible to cement out palladium much earlier in the refining process which would also leave your platinum powder,being the last one after gold. Hopefully simplifying the process. 🤞
Still eagerly watching each part of this series. I guess I was somewhat inspired so I decided to process a batch of old dental gold I have had sitting in a box for a LONG time. Little to no reaction with straight nitric so into the AR it went. I tried to inquart a small portion but I could NOT get this stuff to melt and my OXY torch is DOA after my move. This stuff has become my worst nightmare. I tested the solution and it shows Au, Ag, Pd, and Pt but all in a mix of copper and chromium. And everything buried inside porcelain teeth. As it dissolves and goes into solution it cements right back out and it took FOREVER to finally dissolve. I decided to take a break so my thought was to just cement out everything onto zinc and reprocess with just nitric now that all the metals are very small particulate size to remove the copper. This is where things hit a wall. I add the zinc (like I have many times before) and the metals start to precipitate. As the zinc is consumed more metals come out but the colour of the solution doesn't change at all. I let it sit overnight and the colour never changes. No more reaction with the zinc unless I keep adding HCl but the colour never changes. I can't figure out what is in solution that the zinc won't drop but I'm baffled.
Zinc will cement copper. If it were mine, after cementing everything on zinc,,I’d collect all the solids in a filter and melt into a button. Test with acid to determine gold content. Then inquart with silver (or copper) and digest in hot dilute nitric until the nitric boil remains colorless. This usually takes about six nitric boils to achieve. Inquarting then digesting in nitric should remove all the base metals, silver and palladium (palladium is soluble in hot nitric) plus some platinum, leaving behind just the gold. Then I dissolve the remaining solids (should be mostly gold with some platinum) in aqua regia. A side note: platinum, when alloyed with 95% or more silver, will dissolve completely in hot dilute nitric,
@@sreetips Thanks again for the input. Always appreciated. At this stage all the dental stuff has been dissolved and is in my stockpot. There's something else that made it into the solution though that creates a super thick, sticky foam whenever I add zinc. the foam never dissipates and it just dries into a crust that looks almost like Styrofoam. Half filled bucket and the foam nearly spilled over the top. Quite bizarre. So I went a slightly different route and just went right to iron. I want the copper and had planned to cement out on iron so I figured now is as good a time as any. Everything will be reprocessed anyway. Foam is still there but now it is manageable. I tested the stockpot solution and slight Au and Pd but no other indications so I think the iron will do it. Luckily I can afford to just let it sit for a few weeks so time will tell how this went.
@@sreetips I absolutely agree with you on this 100%. Frankly I would not have even touched the stuff if I knew then what I know now. The super good deal I got is barely worth the effort, time and danger I went through to get this stuff dealt with. And I do use a (makeshift) fume hood. Can't afford a real one but I made sure it has good, strong air flow with NO back-up into the room. Vents outside above the roof line. But if I learned anything it is that in future I will avoid anything with Pt if I can.
Is it possible to cement gold out of a solution using silver or other metal, the same way you cement silver with copper? I realize this wouldn't be the most efficient way to get gold out of solution.
He's getting metals out of solution by introducing more reactive metals. Silver isn't very reactive so it just takes too much time for it to get the gold to drop out.
Yes, we can use copper to cement the gold. Or zinc. But zinc, being high in the reactivity series, would cement out all the metals below zinc, if present, and contaminate the gold.
Those solids could be carbon from the filters you put into palladium/platinum solution. We got carbon solids every time we did that in chemistry. Test for carbon?
A Question would like explained thanks. Why can you not electroplate/cement in a silver liquid form of cementing? I was thinking that it maybe a quicker way of doing it. Just a simple thought. Thanks sreetips if you could explain.
I'm looking forward to seeing these platinum group metals melting. An oxyacetylene flame can reach a little over 3000C so it's certainly possible. However silver and gold melt at relatively mild temperatures around 1000C while platinum group metals need to reach about 2500C before they melt.
Hello good afternoon, I have a solution of ar that was neutralizing, had too nitric, fill almost the glass yes. Being totally neutralized, I put it to heat, and I continued neutralizing, but I did not realize that when heating it continued to activate, then hot metabisulfite and let it evaporate for a while, when I looked I had not precipitated anything, I must assume that the solution when made metabisulfite was not neutralized?I must wait one more day?what should I do? If you don't mind advising me please.
@@sreetips Hello good afternoon, I just neutralized the solution again in cold and relaunch smb without more, that's what had to be done, in the end you are only good for nothing in terms of help, just make money from the videos ...
I’m sorry, but I don’t know what you have there. I don’t offer any kind of tutoring or training. All the information you need is in my videos. My guess is that you probably have very little or no gold in your solution - a common beginner mistake. Good luck to you.
What I'm wondering is how much nitric it takes to refine an ounce of gold, and what the margins are like given the high cost of nitric acid. The HCl probably doesn't account for much, it's $8 a gallon where I live, but nitric acid is about $120 a liter.
@@canonicaltom Any reason why nitric acid is so expensive in the USA? In Australia we pay about ten US dollars a litre for the 68% azeotrope in a 5 litre container. You have to be registered as a genuine user to get it however, so idiots can't easily make tons of ammonium nitrate or nitrocellulose cheaply.
@@AndyGraceMedia It's mostly about shipping costs, since nitric acid is (correctly) considered extremely hazardous. So it kinda depends on where exactly you live.
@@sreetips OK. Thx. I was looking for shot or crystals to make it easier to make small bars. Bar-Z Industrial (@Shadon HKW), on RUclips, sells a HotShot 360 Metal Oven that looks like it'd be good for the task.
I wonder about your waste stream. I noticed you were only using a 5 gal bucket to treat with iron. How much of a backlog do you carry? Secondly, I see you use a excess of copper to cement, wonder if you wouldn't be better suited by using the sodium hydroxide/sugar method in order to remove some of the copper from your waste stream and extend the life of the silver plating solution.
I treat the waste as it’s generated. I only work on my own material. I’m not a professional refiner. I use copper because it’s cheap, plentiful, and creates less waste.
@@sreetips I understand completely. I was just thinking of a way for removing as much cooper from my small silver cell plus using the caustic produced to neutralize my waste before disposal.
@@sreetips I'd be interested as to what those compounds are if you can recall. I would have thought based on the reactivity series that it would prod Aluminium Chloride and Hydrogen Gas after and during precipitation. As it's oxidising and reducing oxides concurrently (redox), I would have though the Ionic reaction would be the same and no different to using Zinc. Guess I have more reading to do as always ;)

Certainly looks like it. I guessed rhodium trichloride . (n-hydrate) Only a guess but the red-pink colour when the HCl is stripping off the water molecules certainly makes me think it could be. Rhodium is only partially soluble in AR after a lot of effort. Don't know for sure but remember in an inorganic chemistry class centuries ago something about rhodium forming a trichloride hydrated salt and it has a weird structure with odd shaped crystals. Hard to know and just an educated guess. PS - searched Wikipedia, the dried out hydrated salt does appear to look sort of like it. ???

Look forward to the melt & the weight.
Shane, there was only a few grams of PGMs. Not enough to do a full refining. I decided to save and add it to my next stock pot process.
It would be cool to see a Platinum metal cell and Palladium metal cell if that were possible. You'd be able to isolate each PGM if it were possible.
Could you use powdered zinc or fine shot to speed it up? Could that cause confusion with the precipitated pgms, maybe to be fixed by some sort of strainer?
Powdered zinc can be used. But it creates a very fine precipitate that tends to suspend.
Maybe they grey sludge was Zinc? It did look similar to my Zinc plating salts. I can't wait to see what the black participate is.

Is the powder to fine for a filter? Questioning why the pour off and not filter and rinse like you have done with other powders.

Could the solids be rhodium?

Or another platinum group? Iridium?
Certainly looks like it. I guessed rhodium trichloride . (n-hydrate) Only a guess but the red-pink colour when the HCl is stripping off the water molecules certainly makes me think it could be.
Rhodium is only partially soluble in AR after a lot of effort.
Don't know for sure but remember in an inorganic chemistry class centuries ago something about rhodium forming a trichloride hydrated salt and it has a weird structure with odd shaped crystals. Hard to know and just an educated guess. PS - searched Wikipedia, the dried out hydrated salt does appear to look sort of like it. ???
Possibly

Sreetips tries to get precious metals by adding zinc…..invents coke cola. 😂

I probably have watched your videos over a few years now but haven't commented i don't think on any of them. I have enjoyed learning the refining process throughout the videos and have also seen your growth as well. I particularly enjoy hearing the quote "looking pretty good man"😆. Its a testament to the hard work and time spent paying off. That needs to be a on some merchandise for your channel! 👍

I was waiting for final video and left it for some free time to improve my English... I always write a comment for @sreetips before watching video)) thank you again! And best regards from Russia. It's a pity that we have lost ads and RUclips monetization for authors.
Contact Jason on his channel mbmmllc he doesn’t know how pure his gold is from mining! That would be an epic cross over video!
