Methods of Gold Mining - Geology In

Placer mining is the technique by which gold that has accumulated in a placer deposit is extracted. Placer deposits are composed of relatively loose material that makes tunneling difficult, and so most means of extracting it involve the use of water or dredging. Gold panning is mostly a manual technique of separating gold from other materials.
