How to Get Started in Gold Mining | West Coast Placer
Gold panning, like all placer methods, is based on the density difference of gold vs water, gravel, and black sands. When suspended in water gold will sink to the bottom of the pan. There are two steps to gold panning, agitating the material and washing away the less dense sands.
