Smelting Platinum/Palladium Catalytic Converters For PGMs..... Success???

[@spiderdude2099]

Just FYI, the tantalum peaks and platinum peaks for some types of xrf guns can overlap to the point where even 100% pure platinum will be read as tantalum. Codyslab has the same problem with gold and tungsten, the reason is because the gold and tungsten X-ray detection peaks are so close together the machine can’t decide which element signal it is. The same problem occurs with tantalum and platinum. Contact the customer support for your particular brand of xrf gun to determine if this is a known problem. Also try maybe shooting a sample of known platinum concentration, something where it’s impossible to have tantalum contamination and see what reading you get.

I have a suggestion for consolidating your high melting metal powders into a chunk of metal. You could take the mud from electrowinning the Pt and Pd out of Cu and dry it out to get metal powder. When we work with precious metal powders in the lab, we press them into pellets in a pellet die then melt them in an arc melter. You will not need an inert atmosphere to melt Pt or Pd so you could use a TIG torch to melt them. Use a large, clean block of copper as a hearth plate and the metal should not stick (unless you get the copper too hot). I think your Idea of adding silver to reduce the melting point of the lead alloy was a good idea.

[@shawnsmith9512]

Industrial separation of cats is usually done with very high heat and using iron as the collection metal though some use copper. I also know that the honeycomb is burnt off before being milled into a fine powder in a ball mill. Also of note is that newer iron sulfide methods of extraction are being used as they can operate at a temp of only 950 deg C.

[@SitNSpinRecords]

Some of those have Rhodium. Palladium will be highest content then platinum then rhodium. (Generally). Converters have different amounts of metal depending on the motor they were used on. The honeycomb is called the substrate. You don’t want that. All you want is the coating on the substrate. that’s where the metal is. The slurry coats the substrate. If you can find a way to get just the coating off the substrate, you will greatly reduce the effort and starting material. (Crushed up substrate is just more waste you have to remove.). That’s about as much as I can tell you without fear of Loosing my job.

[@timw.5030]

I won't tell

[@szucslorant4115]

hello. thanks for your information. Maybe can you tell something about how posible take out the rhodium from catalyc? thanks thats the main problem for me...

[@CJFellowServant4288]

​@@szucslorant4115 there's a KZbin video somewhere that shows how to separate rhodium out of solution of aqua regia using zinc, it's a lot like using copper to pull silver out of nitric acid solution, the zinc is more reactive so it prefers the zinc in solution so the rhodium drops out as black powder. I can't remember who it was but it looked like a Russian smelter. Poor quality video but great quality info. But you'd have to separate out the platinum or palladium first, I can't remember if you need to first but there's a way to do that. Or you could just collect spark plugs and go for the iridium 😂

[@CJFellowServant4288]

I saw a guy put the whole ceramic in a crucible and melt the entire thing, I guess he had a furnace hot enough to melt ceramic, then poured it into an inverted pyramid mold so all the PGMs sank to the bottom and there was a little silver button at the tip of the pyramid after it cooled and he dropped it out.

[@chibigon01]

The platinum in the ceramic beads can be recovered directly from the beads with a complex reaction. I think you will have higher Pt recovery from the complex reaction process than from the smelting process.

They used ion-exchange resins to separate the Pt and Rh. The RhCl3 is what came out of the ion-exchange resin column.

[@scott2296]

I like the idea of silver as a collector, the button could then be dissolved in nitric, putting the silver and palladium into solution and leaving only the platinum at the bottom of a beaker. Then the silver and palladium could each be brought out of solution, one at a time, thus separating those two from each other.

[@bloodyricho1]

Yep I second that. Sliver nitrate is easy to separate and recover

[@gladlawson61]

Chemistry is so f ing cool

[@reneesalipante4611]

Would agree that increasing silver content during smelt process might help increase recovery if it’s actually the limiting reactant for pulling out the palladium. Any way to calculate that? Chemistry is freakin cool.

This is what I found: One of the main uses of tantalum is in the production of electronic components. An oxide layer which forms on the surface of tantalum can act as an insulating (dielectric) layer. Because tantalum can be used to coat other metals with a very thin layer, a high capacitance can be achieved in a small volume.

I worked at both the Stillwater Smelter & Base Metals Refinery in Columbus Montana. We’d actually smelt down Bulk Bags of Catalyst.

[@allenhammer7923]

After smelting I don't see how it would be a black powder? That is what happens in chemical process. Were you the smelter?

[@gustavofiora5393]

It would be useful to stir the molten metal bath to increase the contact surface of the collector metal with the PGMs and if you use copper as a collector, the ideal is to subject the PGM copper alloy to electrolysis, reuse the electrolytic copper and the PGMs remain as black powder to be refined in the bottom of the electrolytic tank, the excessive use of NaO in the flux can involve losses of Pt, the highest production cost is in the flux, sodium borate is not cheap. Congratulations for the job!!

[@snarky_user]

In addition to tantalum, I also noticed some vanadium. Both metals can be used in NOX converters. The converter you used had two distinct sections. Perhaps the upstream section was for NOX and the downstream a typical converter.

The XRF gun can sometimes get confused, so the tantalum might actually be your platinum. I've seen gold show as lead and tungsten on XRF guns before, so they aren't always 100% correct

[@ZE0XE0]

Yep. they need to know what theyre working with to properly understand what the returning xrays mean.

[@ChumpusRex]

Yup. The signals generated from tantalum and platinum have a major feature in common (both signals have a big spike at 9.4 keV). It's similar for gold and tungsten (both have a big spike at 9.7 keV). Where the signals are similar they can be confused, so for best results, XRF software needs to have an idea of what is expected to be in the sample (this is why you get different versions for base metal analysis and precious metal analysis).

[@spiderdude2099]

[@downyourtube]

@mbmmllc The tantalum came from inside the engine. There's no platinum cause it was burnt off before the palladium was during vehicle use (wear and tear). There will always be a lower recovery on a used catalytic converter. The precious metals are coated on the ceramics, as it is in use (vehicle being driven) these precious metals are coming off and blowing in the road..BUT on a diesel semi truck the precious metals are being stored within the soot and collected above in the collector container.. on average those containers hold 2-3 oz's of particulate matter. This particulate matter holds more precious metals then on the used cones you are experimenting with. I have several pounds if you'd like to try a few samples.. let me know. I believe there are more precious metals in the particulates of the soot/ash of a diesel semi truck than in a used ceramic cone. Precious metals are sintered on the outside surfaces of the cones. As soot from the engine attaches to the cones (containing oils and other metals) they get super hot and almost sinter to the cones themselves. This soot/ash goes thru a super heat process of around 3200 f degrees during the regeneration process (cleaning process) and release these materials ..right along with the precious metals. Trying doing what you do with diesel soot/ash... I bet your results are higher.

In terms of using an automotive catalyst- assuming the mass of the base catalyst matters relative to how much PGM recovery you expect- I would suggest only doing the first catalyst. Generally, they will have 5x the amount of platinum or palladium in them vs. the second one. Again, finding automotive catalysts from PZEV vehicles in the 2000-2007 range will the highest potential of all PGM. After some control work, OEM's figured out how to manipulate the air-fuel control to not require the high PGM loadings of the original PZEV cars. Also- all of the gasoline catalysts in the last 30 years are all 3 way catalysts. The first one will do the vast majority of the work, the second one is there for high mass flow (like when you accelerate on a freeway). I know nothing about industrial catalysts- so it will be interesting to see your experiment.

[@Alondro77]

Since there's so little platinum and palladium in each converter, the chemical method with hot aqua regia is usually the best method. You just keep soaking new converter fragments over and over until the reagent is used up. Then cool the solution quickly, and most of the platinum/palladium just falls out. I found that out by accident when refining some old 10K gold jewelry. Fine grey sediment fell out of the aqua regia as it cooled, and I discovered it was metallic, then confirmed it was indeed platinum-palladium alloy.

You can just part the pd/pt if your using Cu as the collector , drop your copper out with iron and go to salt with the pd. You are correct with time and temp curves at the end of your vid and that applies to cupellation as well . Crack that door on your table top , gotta have O2 for proper cupellation.

hi guy - i work with advanced geopolymer technology which is closely related to glass and ceramic technology. we experiment with different recipes of exacting amounts of secret ingredients. most people studying the technology just use clay out of the ground which is full of impurities. anyways just wanted to mention that quartz (silica) can be compared to ice. Water can only hold so much soluble minerals before getting saturated and then minerals fall out of solution and settle to the bottom. Then when the saturated water freezes the dissolved minerals stay suspended in the ice. this is similar to the smelting recovery process you are using. Molten silica also has a saturation limit. I can see it would be important to have precisely measured ingredients to maximize recovery rates! if too much silica is used then some of the precious metal will be lost (absorbed) into the glass matrix. Good thing the cheap collector metals are probably more soluble in the glass than the precious metals. I wonder if oxidized collector metals could be used such as copper oxide powder instead of copper metal because glass loves to absorb and bond to oxides. the molten silica could get saturated with cheap soluble oxides so that more of the precious metal could fall out of molten solution ??? not really sure. great videos by the way - this is the first time learning about Quepel Technology (i have no idea how to spell it) - much simpler than acid recovery/refining methods!!!

This is an awesome reply. I would’ve never thought of silica absorbing PMs. And so you can look more into the process, it is spelled Cupel (Cupelling). I’m learning more about it myself.

That would be valued from 800-1100 dependent on market value and are found on Honda accords 2000-2002. I’ve seen that high value converters can range from $500-$2000 for one converter unit, price will always vary with daily market changes. Knowing market fluctuations for platinum, palladium and rhodium and knowing the valuable cats and especially knowing how to handle your material properly with little loss and high recovery, will give you the greatest success in keeping your profit margins the highest they can be. The loss of value through handling of biscuit material, 5% loss through air born dust alone and if it is an end of life converter, the value could be dropped by 10-20% with that alone as well. Wet and damp or oily biscuit will greatly affect your value and how much you pay for loose biscuit material if you are processing and sending loose biscuit to a smelter. Use respirators when handling material because breathing in airborn dust is dangerous and possibly deadly if built up in lungs. Be safe, be legit and make money baby!

Then go back over it with an N42 super neodium magnet which will lift platinum as it is just para-magnetic. That will also lift a bit of ferrite with it. We put it in a beaker and hit it with nitric. That eats the ferrite and leaves the pure platinum. When we get a couple of ounces, we send it to a commercial processor that has a good enough furnace to process it.

There is a way to test a cat honey comb to see if it has any platinum in it before smelting the cat. Just simply put the torch on the honey comb until it glows red and simply extinguish the flame on the torch and turn on the propane or acetylene back on and blow the gas (not ignited) on the red hot honey comb and if it’ gets hotter and redder and the reaction keep going then the platinum is still in the catalytic honey comb core and you can go a head and smelt it. You can do this with a map gas torch or an acetylene gas or propane gas or even butane gas. If the core does not continue to glow red then there is no precious metals in the honey comb.

Hi Jason! Thanks for another great video! I am super new to most if this stuff, but this came to mind: first, why not have the raw honeycomb assayed, if it's not too expensive. I've heard once ICP-MS is common for catalytic converter assay. For what you are doing there, like the lead collector metal and how cupelling it results in a higher melting point as the lead oxidizes, could your plasma torch be helpful there? Any idea how many thousand degrees it 'burns' at, and if it would be practical to use it for heating the sample? Would an oxy-acetyline torch (5000 F?) be any help either? I also ran across a cupel last night that was rated for use with platinum or PGM. I don't know if any of that helps, esp since you are abandoning lead as a collector metal, at least for now. I just found your channel and you do some great stuff! Since I don't see pricing on your website, I will probably contact you to ascertain some costs. The idea of mechanical or thermal processes to recover metals vs. chemical processes appeals to me a great deal! Also, about a week ago I went looking for mining claims, and finding your channel certainly fills in some blanks for me! Also, I laughed at 4:40 an 'armstrong' stamping mill, single battery lol Thanks again! Oh, somehow .04% of honeycomb weight comes to mind for Pt content in car cats, but it varies a great deal, and that number may be mis-remembered..

[@joshmutch5249]

yeah was also wondering whether a nitrogen plasma torch could be useful at the end.

NaOH + O2 dissolved PtO. 2NaOH + PtO + O2 ---> Na2PtO4 You need to add flour to your Flux to reduce the PtO to metallic Pt.

Have you tried crushing the material fine and using a blue bowl for recovery? For black sand gold recovery i steam cook the black sand in a cast iron pot until it breaks down super fine, usually takes several hours, then put it in the blue bowl water recoverer and end up with nothing but fine metals in the bowl. With only fine gold remaining its simply smelt and cast into a bar.

That’s a rear o2 Honda cat. Should be on all DX/LX accord 94-97 and odyssey 95-97. I typically get 300-400 depending on market lately. The EX vtec accord uses a straight o2 so does the 98 odyssey. 98+ accords are all vtec and had straight o2 or the best slant o2.

Heat is energy. Energy costs money , 3000 degrees takes alot of both. Do the math protip guy. A master can see the math don't add up . You really think 28 dollars worth of platinum pays for all that time in the furnace and then in the oven . You are no master of math.

So another Protip here Loyd, shut your fucking mouth.

@@loyddussault5101 You still haven't convinced me that he wouldn't be good at research and development.

I bet it makes you livid to see someone doing something like this and getting compliments for it, when you go to work everyday with your college education and do something similar and get no acknowledgment.

@@davidoberle9023 He didn't come out of nowhere because you invited responses by saying prove me wrong then adding the arrogant "protip". He's also correct that an engineer with a real degree would be a better choice so as an actual pro with a Master's of science I'm of the opinion that you have been proven wrong. Also, not everything a person does in life gets acknowledgment, and acknowledgment from idiots like you carries no weight.

Keep adding more pure silica mixed with the silver Extract or copper in smaller amounts. You can not take out the power needed to refine.

ANSWER TO THE TANTALUM QUESTION: The Ta reading on the XRF analyzer is in fact Pt. The natural frequency that is excited by X-rays for Ta and Pt are very close to each other and the detector on the XRF can't tell the difference. Are XRF analyzers that have a precious metals mode on them that will treat it as Pt instead of Ta. The same thing happens with Au and W.

@Brian Baff I'm planning to put silicone rubber over the bolt heads, and wrap the exhaust path and catalytic converter in used tire cable chains, with a couple superficial welds along the way to keep everything solidly in place. I know this is not unstoppable, but I would imagine that this would make it an unpleasant job to remove for a would be thief. You guys think this will be effective? 2010 Prius.

@Brian Baff I looked at this, as far as I can tell it's only for 2nd generation Prius. I could probably build one by cutting out a piece of aluminum, but it would be a bunch of work.
