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 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.

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.

@SitNSpinRecords 3 жыл бұрын

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.

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.

A few months ago , came across info that in CATs that have 2 separate bed / sections , both have platinum , but they differ in that the front bed has palladium and the rear section has rhodium . This is a 2 stage catalytic reaction to breakdown different part of the exhaust . And it is easier to process the 2 beds separately , especially when rhodium is so much more valuable . Thanks again

@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.

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.

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.

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!!!

@uspockdad6429 4 жыл бұрын

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. I have a lot of waste material that might contain PT group metals, so planning on trying the cupelling process to recover those.

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.

Youngin, That ain't gonna work with platinum. Platinum melts at about 4800 degrees. That little furnace won't even get it warm ;) And if you wondering where the platinum went in your other batch, it will be in the slag ;) In the gold fields we get the gold out of the black sands, then dry the batch and go over it with a kitchen magnet to remove magnatite. 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. That "Don't try this at home" is sage advice for platinum LOL! Are there any old copper smelters around close? Their slag will be rich with platinum!!! You see, it went into their slag as well ;)

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.

It’s called a Honda O2 Slant and yes because it is slanted on the o2 sensor. Value is around $600-800 but is dependent on current market values. The highest end Honda O2 is the Honda O2 Straight, the O2 sensor will be straight out the side with 4 fins below and 2 fins above the O2 sensor, fins located on heat shield. 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!

But the ones that were original could be anywhere from $60-$350 depending on the car. I know Mercedes-Benz & bmw in some of the older years or worth the most as a Honda accord was around 100 bucks. So if there’s buying these things up at those prices there Has to be a lot more value in them. And the guys taking them off Are the first guys in the chain you still need the middleman and the refinery need to make money

Hey Jason! Does platinum oxidize and lose weight as it comes into contact with oxygen at it's melting point? I have tried melting platinum before and it violently started vaporizing. I even tried slowly approaching its melting point but i was quickly losing the precious metal. Im just wondering if your losing some when you coupelle. Although it dont look like your losing any. Nonetheless thank you for your time making these videos. I have learned a lot.

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 4 жыл бұрын

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

@ChumpusRex 3 жыл бұрын

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).

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. Hit and run , close door to ramp up and crack the door and coast. Another tip is if you believe your loosing precious through copper soaking of the cupel , you will see what's known as feathering. To avoid this , bypass cupellation and just part the prill.

Tantalum I noticed appears when you shot the silver bead, and that makes since because it is a transition medal also Ra too. They both came with the silver and copper. The copper I assume wasn't pure and was from wire scrap. Both Ra and Ta are contaminants from the coin and scrap wire.

@joesmith1628 4 жыл бұрын

Ag has a lower melting point than Cu, better helping to lower the m.p. of your alloy. 25:22 - It's useful to place the metals with higher m.p.s on top, as they will melt last, while the heat from the Ag rises. Also, their higher densities will help push down on the Silver. More cost efficient to use Ag shot, than melting a coin? Haha. Whatever works! Will be Interesting to see which of your formulas produces the best yield. Cheers.
