Bob, three comments on the process. First do they inquart for all four nobles (Au, Pt, Pd and Rh).

Second, are they planning to recover the silver?

Third, if indeed they have resins that are not poisoned by copper, and all the copper goes through the first two bed, they will have to have a third bed to capture copper, like platters have to have, this because they cannot discharge copper to the environment. It is not a technical problem (it is done routinely in all PCB facilities) just an additional step (and cost).
