Yes Mick I have last count 50 cats with about 500 lbs of milled cats which I ground up last year.



The batch I refined was about 100 lbs, this material even though I have stripped it of platinum and palladium will still have rhodium in it.

Rhodium is very very resistant to acids making it impossible to leach out of the substrate.

In the early days cats were being shipped to an African copper smelter, today I believe there is two refineries in the US that have Plasma Arc furnaces capable of processing raw material.
