Gold is often panned from such deposits by taking advantage of its high density to wash away the lighter sediments from a pan or sluice. Nuggets are almost exclusively hypogene in origin, forming mostly in veins, but can be somewhat modified in form and chemistry by weathering, erosion, and transport (Hough et al., 2007).

Extraction of Gold - Element Gold, Au, Transition Metal

Gold can be extracted by washing only when it is present as metal in the form of particles which are not too minute. The washing removes the specifically lighter parts of the material, the heavier gold particles sinking to the bottom. The process is applicable directly to gold- bearing sand, and to gold-bearing rocks after crushing.
