D.Core Lyrics

We have lyrics for these tracks by D.Core:

In Hell You call us weirdos, call us crazy Say what you want,…
Influence So you can suck my dick if you don't like,…
ocean deep How much do I love you? I'll tell you no lie How…
something like this I've been writing songs about you But you ain't go no…

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.

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.


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.


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..

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.

Thank you, Jason, for this extensive empirical research. I think this is the best research you can find on you tube. I do not understand this subject, but as you explain everything it all sounds so logical.


i trust you know exactly what you're doing. still have to say, it pains me to see a 1oz silver buffalo go into a crucible in may when spot was around $16. it almost went to $30 in august!

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.

Any buyer for tantalum here?


I use to do diagnostics , repair & smog testing in CA , 80s-90s .
And with with recently , the last 6 -8 yrs. getting into collecting electronics for repair and going after the precious metals .
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

Thanks, Jason. Raising your algorithm. Lotsa work for small recovery, so far - keep up the good work; I’m looking forward to your next video.
