Extracting platinum, rhodium, palladium together

[greatgems]

I'm looking for a simple way to extract and presipitate platinum, palladium, rhodium all together from catalytic honey comb, no extracting seperate needed. I can melt to ingot and sell for full value so no refining needed just want the simplest highest yeild way to extract all three metals and drop them from solution to melt to bar form. I have read all the many step methods to extract pt seperate but that's not what I want. I would like a method to extract all at the sale same time Any help would be great

You most likely will not get Rhodium with the platinum and palladium, zink would cement them.

 

[greatgems]

But what chemical or process would get all three

 

[butcher]

Seems you have a lot of reading to do. Without that basic understanding you will just wander in the dark, bumping into every problem out there.
Start with HOKE's book. See the book section there is a download, She will not deal with catalytic converters but will cover the basics you will need.
platinum and palladium will dissolve in Aqua regia, rhodium will usually need fusion in bisulfate, there are a couple of methods.

I can melt to ingot and sell for full value

how will you know you get full value without knowing the exact content? does the buyer runs ICP analysts on your bars?

it strikes me as a bit odd for someone to pay full value for metals that still have a long way before they will be in usable condition...

Asa far as i know, rhodium does leaches out of the cat (probably complexed to a soluble salt), and all metals can be cemented as butcher said.

A simple HCL+Cl leach can do the job and same solution can be used for several batches of cat's before exhaustion.

I understand AR does get 2 I like a way to get all 3 and drop all 3 at the same time

I like a way to get all 3 and drop all 3 at the same time

There are a lot of things i would like to see happen too, unfortunately I try to limit my wish lists to things that are within the realm of chemistry and physics.

 

[greatgems]

I have multiple refining accounts where I get direct break downs of every metal in each bar

That's nice.

Have a nice day melting them in significant quantity to get the best pricing. I don't know of any buyer at market price for mixed PGMs anywhere on the earth at any quantity. If you do, please share, I'd gladly pay you much money for it.

Can we get back to the main question I get 2.5-3 percentage off market so close enough I have a commercial account as I have been in the diamond and gold business for years I just want to know one simple process to remove all 3 metals I know that an arc furnace is a good option but I would preffer a chemical process

Good luck getting all three metals with one solution.

I would love to know a PGM buyer paying 98% for mixed metals.

People in hell would love to have ice water, too. It isn't likely to be, however.

LOL Harold.


No one's going to pay 98% on rhodium in small quantities. The margins just aren't there--it's too much work. Look up the JM rates... between them and Heraeus, they're about as competitive as it comes and that's with LOTS of material.

Different story on platinum alloy and even palladium in the form of jewelery material. Mix in the rhodium though, or mix them together, and find your settlement time get longer and longer, "commercial" account or not (I didn't know there were any other types with large refiners?).

Well so you know I'm not moving little gram amounts of metal I tried a cat refiner last month and did 1000 cats found we lost about 13-17 percent realisticly. Now how about a method to remove the pt pd together then a second method to remove the rhodium

my goal was to build up a kilo or so of pt pd then sell it

Rhodium will take much longer but no problem

Good luck...I feel you will need it :shock:

Though i always appreciate and respect folks that deal in large quantities, i find your attitude a bit weird...
You are a medium/large scale dealer, with 1000 cat's batch i assume you turned to a medium/large scale refiner. If they come up short 13-17 percent , what makes you think you could do better?

Oh... and by the way, the search box is in the upper right corner, check it out. Most of the known methods for doing what you want to do is already posted here before... It will be much more interesting and inreacing to see specific questions rather then just asking to be spoon fed right here right now.

No offense, but if you want quick info and step wise process that suits your needs, I'd recommend you to hire a consultant / buy educational articles.

Good luck, i feel you need it to.

would a big arc furnace and lots of silver get all three.

I asked for advice and the best method I have read all the hcl cl ways of extraction all AR posts for cats I'm not looking for hand feeding just a simple answer. I ran that large batch to a cat refiner in Canada so they told me but all they did was run it to Texas was mislead. I have mainly dealt in silver and gold worked into cats fast but know the metal break down in larger shipment of 100 to 1000 pending on the type. My additude comes from the rude assumptions that i don't have a buyer for sold bars of all three or 2 metals. I use a assayer and buyer in Toronto that's partners with JM and have for years. I find when you ask a question of a great or solid method to do something here a few people shut you down and Say you haven't done your reading I thank steve for his reply I'm looking more into hcl cl might try iodine leaching for 10 or so. I love to know if anyone has an idea of a way to remove all three and yeild the best

 

[greatgems]

I also want to do all extraction myself now I will post about my 1000 cat experience wasn't the best because of both the cat refiner and seller

Greatgems, what do mean they came short 13-17%? You don't mean that their assay was low, do you? Or was their payout on the assayed metals weak?
Was it a outfit in Quebec? I remember seeing a website by a Quebec company and their website made it kind of look like they were actually refining cats.
