Very informative post but it left me scratching my head... The way I learned, Gold was extracted from the ore using a process called mercury amalgamation, where the gold ore is ground fine and tumbled with mercury in a large drum. The actual gold bonds (forms an amalgam) with the mercury, while the undesired elements of the ore remain unbonded. After tumbling, the mercury/gold amalgam is drained off and is later separated (distilled) using heat.

I'd be interested to read more about the process you describe - although to me it seems rather counter-intuitive as gold is denser than mercury at room temperature (19.3 g/cc vs 13.5g/cc) so the gold would sink in the mercury. Can you provide any links for further reading?
Nope, you are correct, sorry about that! I went back and checked my source and I mis-interpreted what it said. Sigh
