it should have been possible to make some magnetic gadget for gold "panning".

Provided that gold is the only metal in your ore. That is usually not the case.

You are wrong here. Wikipedia has this to say:

Gold occurs principally as a native metal, usually alloyed to a greater or lesser extent with silver (as electrum), or sometimes with mercury (as an amalgam). Native gold can occur as sizeable nuggets, as fine grains or flakes in alluvial deposits, or as grains or microscopic particles embedded in other rocks.
