Problems in platinum recovery

[slsmp40]

What is the point of waiting for smb gases if you are going to precipitate it with copper anyway?
As long as you use good PPE

Sulfur dioxide reacts with copper quite aggressively in an acidic environment. Just a little bit of time and you will get a much better result with less crap to get rid of later.

I wouldn't call it aggressively but it can be substantially complete reduction to relatively insoluble cuprous chloride, CuCl.

Hello, I'm back on the thread, at the moment it's war.
I'm struggling with CVs, potential salaries and vacancies.....
It's also interesting to make a living from your passion. In short, I've stopped minting coins with my former employer. Not much time to devote to the forum at the moment.
In short, my heart sways between some very interesting proposals

-in Dubai for the big Au Ag pgm's.

-in Switzerland for Rolex (advantage, watches bought at factory price 8k$, just cast iron no refining =(

-in France paid like a bum >$3000 =( =( =(. advantages training on all pgm's Pt Pd Rh Ir Ru, in-house training also offers in-depth learning on osmium https://www.osmium-preis.com/fr/

(1552 Euros/gr) so I think my heart is set on them.



If I get the process and the equipment used for 999 releases on platinoids, you'll be informed =)

A few photos of what I was producing each day, not to be the guy but rather to share a little with you =) even if it's not the substance of the discussion






Here's an example of quartation (when you kick ass, Boom 1 million on the table)




When I tell you that platinum rarely follows gold, take a look:

when I started refining on my own, I sometimes had to attack large blocks of silver with many interesting cuts: Pt Pd Ir Rh. I diluted hno3 65% with 20% H2O volume, and I did not heat the solution, which allowed me to remove a few grams of pgm's including platinum on ingots of several kg each, so the proportion 1/10 or 1/20 largely exceeded.

see photos


sometimes even on 15 kg ingots, as here



I also think it's probably due to the fact that perhaps the pgm's had a tendency to cement naturally to the silver (oxidation-reduction chain), whereas the silver was being digested by the nitrate at the same time.

I have unfortunately lost a lot of photos and videos on the subject. (remember to back up your data on disk, smartphones don't like acidic environments).



pour le palladium , nos amis chinois zhang (video postées avant ) m'ont avoué utilisé du permanganate de potassium (KMnO4) avec [C] et T° a respecter scrupuleusement pour précipiter Pd en 999 assez facilement et même avec de parasite en quantité importantes , mais je préfère faire plus de recherche à ce sujet avant d'en parler



for 4 metal :



I haven't used their system but I could eventually send you some photos and video of my pre-configuration installation +- 1,500,000 euros, very well thought out I could have built it for +- 80,000$.



They take a hell of a margin when they do it and send it to you plug and play.

Personally, I can tell you that all the orange valves and the plastic come from Germany and are often pre-assembled in Turkey. The Turks are magicians and don't use miller's or whowill to get 999/1000 in gold.


Just one last word: I hope that a complete noob, a real shit at chemistry, will be able to read me one day, the kind of guy who gets reprimanded on the forum with this kind of comment: ‘no urea in acids, it could explode, you really should see the safety section...... because I must admit that's how it started for me. 90% of the time I do the opposite of logic, I also experiment with processes that in theory shouldn't work.

So to this guy who doesn't know anything I'd like to tell him that anything is possible and that if he's motivated and doesn't listen to his real assasins of discovery .
‘It's only a matter of time before you fly with your own wings, go for it, try it out, beat yourself up, look like a loser, an incompetent, but never give up. And if you feel alone and misunderstood, send a message, it's free and there will always be a kind soul to guide you.

nothing is impossible if you trust in you bro .

see you

now i'm shure KMNO4 for palladium précipitation. look purpul color
look

https://www.indiamart.com/proddetail/potassium-permanganate-kmno4-23580896773.html

 

[Yggdrasil]

That has nothing with values to do.
If you dissolve PotassiumPerManganate in water it has a beautiful strong violet color.

 

[Abdoulapapatte]

Yggdrasil my friend, you'll really have to explain to me how you can see the violet in a dark solution .... I'm talking about the colour of the powder he puts on before it falls into the brown solution.

In the beginning I started recovering palladium in the form of permanganate and I encountered many difficulties. To begin with, it is extremely staining, and you also have to be very careful with the quantities and time, because the palladium sponge that is formed redissolves easily and is difficult to get everything out at once. I do not recommend the permanganate method for palladium recovery.

 

[Lou]

Honestly that's one I've never heard of before and now I know why!

Honestly that's one I've never heard of before and now I know why!

One of the most worthwhile features of this forum is that it has become a global membership and because of that we get input of methodology that many have never heard of, some of it good and some of it not. But the end result is everyone here can learn from some of these threads and come away better informed.

There are many techniques I have learned from this forum that provide short cuts and new techniques that I would have never learned if I had stayed in my own little world.

 

[Abdoulapapatte]

I quite agree about permanganate if you don't master the protocol, with the references, the steps, we quite agree, before there are also key steps to do temperature, pressure, time scales.....
However, after waiting a long time, I did get some answers from the Chinese, and here in the video it was indeed the case. Another piece of information that everyone already knows: we always adapt to the material we're dealing with.
Here it was the catalytic converters petrol and diesel mixed, diesel are more charged in Pt.
For petrol it's more Rh and Pd.
