With all due respect, PGE recovery is not comparable to recovery of Au from a heap leach operation. Traditionally, PGEs are recovered in a sulphide concentrate which is subsequently treated in a smelter/refinery. They are not recovered commercially via heap leaching.

Thank you for the informattion. I surmised that from the link I left on the site.

That means that unless they end up in some flotation concentrate, they are worthless?

I doubt they can be extracted from the stainless steel process
