I learned in the late 80's from this study how fast different size gold will drop in a stream/column of water. It sure opened my eyes as to what it does in a pan or sluice.
Since then I have not worried so much about Losing Fine Gold. It takes just a little longer to get the Fines to drop through a Fluid Bed, but not much.
I got a KICK out of how they described making the individual particles of gold. It must have taken Hours under the microscope to pick them out!!!
