Thank you, RogueRose! I've downloaded the two papers and given them a cursory glance because I've been reading this delightful text from the 1940s on the recovery of precious metals by Hoke... Some real gems in that one, like "taste the washings until they are no longer sour"!?!

One additional note, since some of you appear to not be taking my posts here in the spirit intended. I thought the choice of thread title and my somewhat irreverent tone would suffice to show that I am not approaching this as a serious business venture or even as some kind of "get rich quick" scheme. I'm just a curious fellow who has an interest in electroplating and saw a potentially interesting tangent in recovering Pd from PdCl2, admittedly because the advertised price on Alibaba seemed absurdly low, but once I put more than a few minutes of effort into researching just how one might go about doing this it started to sound like a fun project. As long as fuming nitric acid or cyanide isn't involved, that is. Or visits from the DEA/ATF/FBI/FDA/etc.

Could just use the search engine--this has been covered before here (by myself).

In any case, you will not get a discount on palladium buying it as its dichloride from most supplier. I make the stuff and it goes for a couple buck per gram premium in bulk as a fabricated good. If it seems too good to be true, it probably is.

Very rarely there's a discount on sponge or on bar stock. A few years back, there was about a $22/oz spread on taking 50 troy ounce Pd bars and dissolving them all and making them into palladium sponge. Worth while.

I suggest instead you buy scrap dental gold and separate the Pd, Pt, and Ag and Au just like garage chemist has. You will find that to be both educational and profitable.




Neither flask nor beaker.

I think China is getting better, depending on what your spending it may be worth getting a agent.

As for drug making, most people use drug related chemicals all the time. Personally i use one a great deal, what worries me is soon it may be listed. Not sure what I will do if it does get listed, bloody drug cooks using water is going to screw us all up!

Elemetal Direct will buy your palladium. They pay 80% of spot based on purity of your metal. So if you had 995 pure palladium then the would pay .995 X .8 X spot = payout.

I bet if you convert it to PdCl2 and sell it on eBay, that's where you'd get top dollar. They'll pay as much per gram of PdCl2 as they will for Pd metal! And PdCl2 is only like 60% Pd. Some of them are also interested in sassafras products, but not all of them are. It probably shouldn't matter.

Hmmm, isn't nitric acid virtually impossible to purchase because of DHS restrictions? Also, while I feel I am very competent technically, I am less confident in my ability to safely use nitric acid or cyanide solutions, to name 2 that are commonly used to recover PGMs.

I can go into a local store and buy a gallon of nitric acid for $60, in the middle of Manhattan. I can buy sodium and potassium cyanide by the pound too. Incidentally, is there an easy way to extract PdCl2 and Pd dust from an old carpet by using a CN salt? Nitric acid would oxidize the whole bucket, I'm afraid.

Those things are legal to sell, just very difficult and expensive to ship.




The first step in the process of learning something is admitting that you don't know it already.

I'm glad to see there is still some interest in this topic, even though the lot of you can't seem to resist lecturing me on the economics, while being suspiciously circumspect about the chemistry. Case in point:

Yes, I did find your post via google search - http://www.sciencemadness.org/talk/viewthread.php?tid=71811 - and it was actually what led me to start a topic on the subject here, because I wouldn't exactly describe your post as having covered this subject. For example...

Hydrogen will rapidly reduce it? My understanding - knowing all too well this isn't saying much - is that you need to heat the salt up to "calcination temperature" then pass hydrogen gas over it to reduce it back to the metal; that doesn't sound practical for the garage chemist, and it would produce gaseous HCl as a bonus.

I am also aware of using a more active metal such as Zn or Fe and HCl to precipitate out the Pd, but I am concerned this could result in contamination of the Pd if too much of the active metal is added; and isn't finely divided Pd - which is what you will get from this approach - itself soluble in HCl?

Your other brief suggestion was to use boiling sodium formate solution at pH 5, but the limited information I found about this approach is that it is a very vigorous reaction and requires careful control of the pH. Furthermore, I'm not sure of the most practical way to adjust the pH: start with sodium formate solution (likely highly basic as it is a salt of a weak acid and strong base) and add formic acid or start with formic acid and add sodium hydroxide?

It's probably a moot point now anyway, since I have not been able to register my business on Alibaba - it asked me an email address when I initially registered, I confirmed the email address, then it asked me to enter my password, but I never specified a password in the first place, and doing the "I forgot my password" resulted in an error page. Rather annoying, all of this.

AFAIK, this requires nitric acid or cyanide solutions; I'm not really interested in dying over some dental fillings.
