Hi Mike, WOW - this chemistry class is getting really intense!!! Congrat's on getting the red salts onto the filter paper! I see we can look forward to class #5! Thank you for all the time & effort you're putting into this project - your students appreciate it!! Thumbs up! Stay safe! Jim
If you still have that residue that you suspect was silver chloride, pour some ammonia on it and see if it dissolves. Silver chloride is soluble in ammonia.
I'm willing to bet that some of this palladium came from the older ram that was sent to you all Ground up. The MLCCs on those ram were ground up too & some the older ones would probably contain palladium
Id keep testing. Confirm copper with ammonia in the spotplate. Maybe rehydrate the crystals, cement on zinc or aluminium. Clean up with hydrochloric, Get it back in solution and do some tests. Im totally winging it, but noone else has said anything yet so here is my two cents, and you're kinda winging it too, just with style. And more knowledge. And practical experience. Ha. Good luck man. Maybe dont expect a yield this time, just lessons. And probably dont expect to separate the PGMs individually this time round. Im not doubting you, for the record. Im glad you shut that fume hood door as quick as you did during the boilover. To set aside the palladium precipitate until you accumulate more, or continue with a learning experience is another question. I hope you're mostly enjoying the experience whatever you choose.
You are seriously correctly anticipating most everything happening in episode 5 which I have been filming. Go buy some lottery tickets. You are on a roll.
@@omegageek64 Iv had a bit of luck lately, maybe that was the universe rebalancing. I dont mean to condescend but be careful, whatever you do. You know the dangers. Somewhere Ammonium Chloride comes into play, unless youre substituting and i just dont have the knowledge to see it. Though i think that is for the separation of the PGMs. Good stuff! And good luck!
yep like i said in the last part i would of used pure zinc with all of your liquids then all of your PGM'S would of dropped out as a black powder then you could of done nitric treatments till nothing goes into solution that way you would of separated the Palladium from the platinum also, streetips is very useful to watch when it comes to his stock pot he is very informative
I really do not know the theory very well; but looking at a reactivity series chart i would have thought zinc would also precipitate iron, cadmium, bismuth, copper etc. as well (assuming such are present. like I said 100% tyro talking. 😁😀
To be honest, I wouldn't waste any more resources on that 2nd solution. As you said there is not much concentration of any precious metals, and the crystals are probably mostly ammonium chloride, you can put it all back in the stock pot. Save the palladium filter paper till you have more. Important thing was you got the gold out. 👍
I have never done PGMS BUT if i were going to id prolly use zinc powder to drop everything out then clean the basemetal with hcl or nitric. Then use the ammonium chloride to refine
@@omegageek64 I don't know how to do a PM but if you can get in touch I have an XRF available. Since I love your videos if you wanted to send it with a SASE and I'll test it and send you the results back with your sample.
@@omegageek64 Which method do you usually follow? I have a large stone that has both iridium, rhodium and gold, but I can't extract any of them separately. What method do you recommend?
@@88.Rass.88 You are in uncharted territory for me. Gold is easy. I'm getting the hang of palladium. But even Hoke had issues with rhodium and iridium, though she was more comfortable with iridium. Pulverize the stone as fine as possible. Heat to high temp to oxidize irridium. Extract the gold with aqua regia. Drop the gold with copperas and leave any PGMs in solution. Save the solution and undissolved original material and seek help from a PGM expert.
@@omegageek64 I just got acquainted with your channel, I saw that you are presenting valuable content, I said that it is better to use it, you can see gold in my stanos test, I even tried with copper and zinc powder, but I didn't get any results, my stone contains titanium, nickel, mercury and lead. , and there is also some silver, does the presence of high metals cause a strong alloy with gold to prevent gold precipitation? Unfortunately, there is no platinum group specialist in my country, if you have a source, I would be grateful for the introduction.
I don't know which, if any, chemicals can replace it. There are some videos on UA-cam about how to make sodium chlorate. That may be a subject of a future video on my channel as well.
What information do you recommend for beginners to processing their own reclamation?I've harvested on free time for around 10 years and Connectors and enig getting out of control.HELP😀
I kinda know for sure that you didn't have the concentration of the PGM solution high enough. Think Sreetips did that couple of years ago and I'm pretty sure he had it from hoaks book. Faintly I remember 20g/l Pt.
It is amazing you decided to record, alot of this is nonsense. When playing with chemicals you may want to do some research on what STUFF that is. But im sure you want to make 10 videos for one process.
at 00:42:15 I'm pretty sure that's a hexachloroiridate salt; I tried dissolving iridium with poor man's aqua regia (potassium nitrate instead of nitric acid) and ended up with a similar compound in the past.
I love those foreshadowing notes XD They add so much to your videos! I think sreetips had in one of his videos information that depending on the composition of the mixture, the nitric boil can drag platinum a bit even without aqua regia. Your videos are so relaxing. Great watch!
put it back into solution and use zinc to cement out the metals and then begin again, if you had used zinc the first time to cement out it would eliminate the copper contaminant

Trial and error Mike.
Its all progress... nice work.

One more thing you may have preempted...
Using HCL and H²O² instead of nitric will elimate any chance of residual nitric problems.

Might want to keep some litmus paper handy for pH testing.
Mike you can order ammonium chloride and sodium chlorate from lab alley in the usa
@54:23 it would be nice if that white dish was clear, so that one could see if it is a "dark green" or other dark collor, other than black.
You need to do the same for gold
you should be able to find sodium chlorate tablets at a pool supply store
It's probably best to store it for now and move on to the next project
I thought a red precipitate was called red brick palladium ?
And I thought platinum precipitate was yellow ?
It is
Invest in a used XRF unit to determine contents of your results to avoid unnecessary tasks.
That's easy to say. Not in the budget unfortunately.
@@omegageek64 I don't know how to do a PM but if you can get in touch I have an XRF available. Since I love your videos if you wanted to send it with a SASE and I'll test it and send you the results back with your sample.
Have you tried getting gold out of the thermal printer heads yet I've got a few and trying to find someone that has done it
Platinosis is a real worry. Please consider better protection.
I say you have rhodium in your solution.
You aren't the first to suggest that. Could be. Likely not enough to recover, unfortunately.
@@omegageek64 I don't think so sir, it's worth trying, of course you are the expert yourself

Dmg dimethilglioxime that's works especially for pd !!
Maybe remove the copper first to make the solution more pure
But how...is the problem. NItric will also put palladium and traces of platinum into ze solution.
@@NOFX0890 use a couple of pieces of angle iron to cement out the copper
Any more reactive metal will cement out both the copper and the palladium. Wait until episode 5. I found a way to separate them.
Im wondering if any Nickel has come along for the party also. Looking forward to p5.
You can use sulfuric acid
Is any other chemicals can replace sodium chlorate? because I may not able to get it in my country,.
I don't know which, if any, chemicals can replace it. There are some videos on UA-cam about how to make sodium chlorate. That may be a subject of a future video on my channel as well.
@@omegageek64 Thank you so much, looking forward to see that.

WHen you rinse also you need to use saturated AmmoniumCHloride solution because the Ammoniumhexachloroplatinate easily dissolves in water.
I've watched simular video's and it seems going on the next day isn't such a good strategy also.. all kind of unexcpected results happen.
I've seen you can also do the stannous tests on bigger papers, then you get that chromatography effect of shifting colors.
What's the name of the book I'm not seeing the link
Cm hokes refining precious metals
Refining Precious Metal Wastes by C. M Hoke amzn.to/45X5Wiu
Your teste have pink rose color
Really milking that stockpot, looking ahead I see a part 6!
What about tantalum?
It is amazing you decided to record, alot of this is nonsense. When playing with chemicals you may want to do some research on what STUFF that is. But im sure you want to make 10 videos for one process.
Piranha solution clean a lot of stuff but you have to use sufuric acid and hydrogen peroxyde
Try dropping a pie of aluminum to drop your Palladiam
Take a sample of the green crystals and test them with stannous . If they are PGM salts they will react accordingly.
at 00:42:15 I'm pretty sure that's a hexachloroiridate salt; I tried dissolving iridium with poor man's aqua regia (potassium nitrate instead of nitric acid) and ended up with a similar compound in the past.
Boil it
Why is it impossible to drop all the pt from the solution
i saw someone doing this process and separating pt from pd
I love those foreshadowing notes XD They add so much to your videos!
I think sreetips had in one of his videos information that depending on the composition of the mixture, the nitric boil can drag platinum a bit even without aqua regia.
Your videos are so relaxing. Great watch!
For clarity of results in your Brown solution use a spot plate please, then you will know for each reaction.
put it back into solution and use zinc to cement out the metals and then begin again, if you had used zinc the first time to cement out it would eliminate the copper contaminant
