Gold Prospecting and Gold Panning How-To - mdpub

If you load a pie-pan shaped container with gold-bearing gravel and sand, proper agitation in water should cause the gold to sink to the bottom, while washing away the lighter stuff that rises to the top. Eventually, all that is left in your pan is the heaviest minerals, including (hopefully) some gold. It really is about that simple.
