  • Direct smelting of catalytic converters for the recovery of platinum and palladium. This experiments show the process Jason used to try and recovery the Pt, Pd, and other PGM from catalytic converters. Using flux, crucibles, and a propane fired furnace the ceramic honeycomb is dissolved and the platinum and palladium are collected with a lead and copper collector metal. Check out how much precious metal is collected at the end!

    with hot work like this, the very small particles of metal do not have the weight to move against the convection currents in a crucible so stay quite evenly distributed throughout your slag. you need a rotating furnace that brings all the slag into contact with the collector metal at the bottom of the crucible. the molten metal collector stays on the bottom of the crucible and the rotating agitation of the crucible brings all the flux into contact with it allowing it to do its job of alloying with your target element.

    Hi Jason
    It is difficult to recover catalysts by gas smelting. Refineries do it in electric arc furnaces where high temperatures are reached.
    On the other hand, when metals such as palladium are copelled, the final button usually does not reach more than 50% purity due to the high temperature of the palladium.
    So the lead is not oxidated 100%
    There are two types of catalysts. Some contain only palladium and others contain palladium, platinum, and rhodium.
    On the other hand, it is always convenient to grind and mix well. For this type of analysis, litargirium (PbO), is usually used as a collector and some charcoal to reduce the lead.

    Platinum, Palladium, and Rhodium are the precious metals used in catalysts. The use of Platinum vs. Palladium seems to follow which one is cheaper, as they both do pretty much the same thing. Many modern catalyst don't have any platinum in them...
    Also- if you are getting a catalyst off of a car made in the last 20 years, there are generally two of them- the front one will be loaded with 3-5x more palladium, and maybe 1.5x the amount of Rhodium. In terms of ratios of the precious metals- on the front brick, it will be in the 40:1 range of palladium:rhodium, and on the second brick, closer to 5:1.
    Interestingly enough, the very first PZEV cars, in the 2000-2005 time frame will have the most metal in them. Lots have been learned since then- and the metal usage is much better optimized vs the cost. Find the cats off a PZEV BMW, Ford, Honda, etc of that era, and you have the best potential for higher recovery.

The company saves all the dust from production as well as broken bricks and sends them out to a contractor to extract the precious metals.

    I have a theory. The ceramic is zirconium dioxide, which melts at 2715ºC, almost 700ºC higher than platinum. If it doesn't melt, then the platinum or palladium coating may not dissolve in the metal. Acid extraction with HCl and either hypochlorite or nitric acid seems like the more viable alternative.

In the past, 60 Minutes or a similar show told of how some companies were disposing of hazardous expensive-to-dispose of zirconium and other wastes, in plant fertilizers, in the clayey matrix/filler material of the pellets, basically unloading it in fertilizers and not telling the farmer customers. And disposing of it via loophole, on farmland and in the food animals and people eat.

    In smelting you have a few challenges. The catalytic substrate is a carbide ceramic that gets treated with a silica dioxide and aluminum oxide "wash coat" to increase surface area with an addition of ceria zirconia to promote O2 storage. the core is engineered with rhodium as the reduction catalyst and palladium as the oxidizer or just platinum as it does both but that creates side reactions.
    My "guess" is that the substrate is your biggest hurdle as it is engineered to to withstand 1000 Celsius. The zirconium could be an issue too. You had high palladium values so I would expect to see more rhodium though that would get eaten by the catalytic reduction by use.

      Rhodium is very expensive, but is the very best catalyst for NOx reduction. A catalyst, by definition, doesn't get used up in the conversion of the pollutants into CO2, nitrogen and water.

    Two possibilities come to mind. 1. Smelting relies on the target metal being in a molten state, so that when a bead of it comes into contact with the pool of collector metal, they fuse. Any oxide on the bead/pool interface will be swept aside as they fuse. Platinum's ridiculous melting point means that it will be in the form of solid nanoparticles that may or may not actually sink in the slag, in a manner similar to the way ultra fine gold floats in the pan. Sorry, but Jet Dri isn't an option at 2000 degrees. The platinum particles are likely to be covered in a thin oxide layer that simply will not absorb into the pool.
    2. There might not have been any platinum in the CC to begin with. Palladium, rhodium and platinum all work in CC applications. The metal selected might depend their relative spot prices at the time of manufacture. The metal content also varies depending on whether the CC is designed to catalyze reduction, oxidation or both, and that is determined by the application.
    I think chemical refining is going to be your only option other than using a graphite crucible at 3000+ degrees under argon.

    Nice experiment I hope you get an answers to a solution for the smelting process to work, Otherwise couldn't you have pulverized the material into a powder and ran it on a small shaker table as the material you are trying to recover is heavier than gold? Then take what ever the table sorts out and smelt that material?

    To me, what you had, is a pre cat which is different than a normal converter. I believe it's because of its close proximity to the initial point of combustion with less catalist used. I was a auto mechanic for 25 years, the ones I believe have more precious metals are your larger luxury vehicles, suv's, German or japanese imports. I could go on, Mercedes was the one I recycled for the most amount of money..and it was also one of the biggest. Hope this helps

That's why you found palladium ( that's what you are supposed to find in a cat converter from a petrol driven car) instead of Platinum which is only used in Diesel cars. Anyway, very interesting stuff.

    Nice. I wonder if just leaving the pgms in the lead longer would work out.they are more dense than gold. Its cool going through the learning process . figuring out how to make it work. Fun fact , platinum oxides ignite alcohol. There was even a cigarette lighter design was made around that concept from the 1920's. After the main crucible and cupel cool, I wonder if a drop of alcohol would ignite when added, after smelting platinum . do you live in an area the sands roads in The winter? I wonder how well a shaker table would work for getting out the pgms from that road sand. There's supposedly enough to mine on a busy road...it can be up to few ounces per ton if the sand is reused year after year and sees alot of traffic. .I think the cupel ate your platinum. I also think ceramic is the problem and if you can seperate the metal from that, which is where the chemicals usually come into play. smelting would be possible. Maybe the shaker table could help woth that on some level . the converter works on the same principles as the pgm oxides and alcohol ignition. The pgms are bonded into the ceramics. They react with the exaust and heat up intensely , both incinerating solids so they dont clogg the ceramic filter, and so toxins can be captured by exchanging them for pgms in the exaust and vice versa in the ceramics. Those are the particals in the road dirt btw. The green and red slag looks like iron and pgms also. Funny , I have rock samples that look lie the first slag. Same transparent drab green on a black base.

  • @God-s_Kingdom

    there is a monthly guide available that lists the the amount in $ that each catalytic converter carries by make and serial number.
    Some Cats have A Lot of metals, and some almost nothing. Most 3rd party replacements have Little PMGs Try one from a dodge 2500, there should be a lot in one of them. get it from a muffler shop not ebay, many of those are already acid washed.
    Gasoline cats are mostly Palladium (1oz/10 average) with a little Platinum and Rhodium( 1 oz / 100 +/- cats).
    Diesel Particulate Filters are mostly Platinum then a little Palladium (with RH)
    The metal makes the burn temp.
    The metal is usually Fumed onto a ceramic honeycomb, very equally distributed and deeply penetrating the ceramic. The ball/bead catalytic converter the metals is only on the outer surface of the ceramic beads.
    There are also metal based catalytic converters, I think they would be better for Vulcan style recovery vs alchemically.
    Do you have access to a centrifuge? no? make a holder with a wire and swing the liquid metal before you pour it, that will help concentrate the heaver metals.
    if you liquefy the ceramic you might try ultrasonic vibrations to get the PMGs to separate out of the ceramics. It is Closely Associated. Stiring may help also. Think of it as rendering lard from fat.

    Of all the comments only Seymour Pro made a reference to the XRF gun. I don't understand why you are working in blind and just assume things when it just takes a minute to test the materials along the way.
    1. Test the cat material to see what proportions of PGM:s there is. If you have 20% Pt and 80% Pd when you start then you should have roughly the same proportions when you are finished or you have losses along the way.
    2. Test the lead and copper used as collector metals so you don't add anything that way. There are especially high grade lead sold for doing precision work assays via cupellation.
    3. Test the collected metal as well as the slag to see what you collected before cupellation.
    4. Test the beads after cupellation as well as the cupel. That way you might be able to detect any losses when cupelling with copper.
    All in all an interesting video and my guess on the color change of the slag, oxidation state of the surface, some oxygen have penetrated and oxidized the surface layer. But you have an XRF, use it to see if there is any difference between the composition of the red pieces compared to the core green slag. :-)
    I wish I could afford an XRF, it's such a versatile tool when working with precious metal scrap.

    I have done similar experiment. The best flux for smelting cats is Cryolite.
