Thanks for weighing in on gold centrifuges, E.C. But I think you kind of missed the finer point there.
Long-gone posted a website URL wherein the Swiss were hawking a centrifuge placed sequentially in a demanufacturing grinding circuit which produces delaminated plastics, fiberglass, and sintered pelletized compound metals as a "one step sorts all" type of throughput process. They even gave these nice graphically illustrated piles of pure copper, pure gold, pure aluminum, et al. to drive home their point.
This circuit sounds great on paper, and even has some cute graphics.
But as a practical matter, no one puts in a pound of worn, US, post-1965 quarters (approx 6) into this centrifugal washing machine and out pops a pile of .750 outter clad copper, .250 nickel bonding, and the inner core of pure copper into two distinct piles. Ditto circuit boards, tire casings, mixed scrap.
Oh, and the edge reeding from all those sintered quarters?
Well EVERYONE KNOWS all THOSE are set aside in perfectly stacked/perfectly parallel rows for re-use and re-attachment by the US mint for their reeding machine back in Philadelphia, over in Denver and out in San Fran for all these comemorative state quarters currently being pumped out by the gazillion. You know how many reeds it takes per quarter? WHEW!!!
