Speaking with his son, he informed me the leach was heated .
Some where I have Dr. Lashleys son's telephone number, he lives in New Mexico and has copies of his fathers works available for sale.
Now that you guys are vesting an interest in SSN as a probable leach, I might suggest some one invite forum member jamesrobinson from the Uk to once again become an active member of the forum.
Some of jamesrobinson earlier posts from this thread.

My thoughts for collecting the PGM's would be to ball mill then run the fines through an electrostatic separator, subjecting the heavys to a heated pressurized leach such as SSN
I'm personally interested in using SSN for leaching gold and silver because of its low toxicity. I had posted the documents from Lashley in an earlier post expecting some response in its use.
Seems every one prefers the stronger acid leaches - where there's smoke there's fire.

Frog says"The single most important element of the hydrometallurgical method of removing the ore is to be able to get the metal in the ore into solution".
Wouldn't a bath of acid have to eat itself from the outside in?
If this is the case, then there would be no need to dissolve all of the substrate unless you intentended to recover all of the other metallic values.
I'm still looking for someone to do some" before and after" fire assays of my material to see how much it contains and what percentage, if any, that I have recovered .
Anybody interested?
That is not necessarily true markqf1. Much depends on pretreatment of what you're extracting, and what you're extracting it with. There are acid cocktails that will not affect an ore, but will remove the fine values present in that ore, so long as they are not completely encapsulated by an inert material. I should also mention that Frog said this was used for leaching ore, not for leaching from a catalytic converter. It is incorrect to assume that they are equivalent processes.
As for fire assaying...I'm set up for it except for the cupels and inquarts.
The amount of assaying requests I see on this board makes me strongly consider purchasing a used ICP machine to do analyses for you all. Too bad the upkeep on those is $$. If only I could find a used one for 20 or below.
Lou said:They're pretty nice aren't they Irons?
My friend's work has about 20 of them, and 48 GCMS amongst many, many other machines. Probably 6 million a year upkeep on them, more with standards' prices these days.
Ever used one (ICP) Irons?
