Thanks Josh
That is what I was trying to say. Yes there is gold but 100lbs of boards
is not enough to get excited about, even with mil parts and gold leads.
Each part has a few cents of gold or it couldn't have been manufactures
in the first place.
I though I'd point out that gold leaf is even thinner than what is
typically plated on electronic parts. As I stated most plating is 15 mil
or .000015 inch. Gold leaf is about .0000001 inch.

Hi Joshua
It seems like you are the person to ask. I did some calculations showing
that one would need a large area of PC boards covered with gold to
get to an ounce ( w/ typical plating ).
About how much gold would you expect to recover in 100 lbs of
average PC boards. My guess would put it in the 1/8 of an ounce
or less. Surely not enough to pay $500 for a pile of boards.

Well certainly he is trying to rip you off, why else?
TBH, you usually dont handle such small amounts of salvage... to
offset costs we were dealing with 1000lbs or more of scrap. Im not
sure on the actual gold recovered, I didn't handle the precipitation
of the gold from solution, i handled the grunt work of smashing up
chips and stripping boards for the acid bath.
So if your actually looking to make profit in this field you need to
deal in scrap by the truckload
