Platinum and Catalytic Converters

electrokinetic - 23-7-2012 at 13:40

Someone, please, tell me what the catch is here.

There are guys on ebay selling catalytic converters for $80 and saying that theres a full ounce of platinum recoverable. Sounds too easy if one is able to get their hands on some aqua regia. If life has taught me one thing, it's that if something sounds too good to be true, it almost always is.

I'm asking here because I couldn't find a previous post on this topic, and all google comes up with is more people selling catalytic converters. I'm not one to take the snake oil salesman at his word...

I doubt that there is 1 ounce.
These guys pay 200$

and considering that there is rhodium and palladium too (See http://en.wikipedia.org/wiki/Catalytic_converter).

so if I assume that there is 400$ of combined metals (platinum, palladium, rhodium)
and platinum is 1500$/ounce, palladium is 1700$/ounce and not sure about rhodium,

for sure, there is less than 0.5 ounce (14 g) of platinum in there.

You also have to remember that just because the value of the combined metals may be x dollars, you won't get anywhere near that value when you sell it. The refining costs can be substantial.

Aftermarket cats contain almost no PGM. That's the reason you can buy one brand new for 150-350$. OEM ones have more precious metal in them, but with new technologies, the amounts keep getting lower. If you are looking in leaching Pgm from cats, buy OEM cats from 1995 and before from totalled car without high mileage
