Hi, Bruce–
It occurs to me that if I wanted to come up with a swindle, I would have a ore
sample from somewhere else analyzed and report those numbers (and maybe salt
the mine with such samples), or crib the numbers from some report from another
mine – either way I would not come up with such weird numbers unless I happened
to grab a sample from that northern Urals area. They seem _almost_ too weird
to be anything but honest. If it is a scam, the perpetrators are either clumsy
or think many people will figure as I just did.
The need for a "secret process" is the real joker here. If gravity separation
were always economical, there would be little heap leaching of gold; I do not
know how close those concentrations were to the limit where gravity separation
makes sense (the price of osmium and iridium would be critical in this case,
with those numbers). Then there is the problem of isolating Pt from Au and
whatnot (if cyanide works for Au and not Pt, why not use it here?). I wonder
how profitable this proposition would be if the secret process had to be
replaced with traditional practice?
