Placer gold ore with high gold content mostly exists in the form of particles. Therefore, the ideal method to process placer gold ore is gravity separation.Gold can be found almost anywhere on the planet, and the key to recovering it is knowing what type of gold it is. Gold deposits can be grouped into two primary classes placer deposits, where the gold is exposed from weathering and erosion, and hard rock, where the gold is still trapped within the host rock.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.Mar 13, 2018 Placer gold, roughly 75-to-95 percent real gold comes in a variety of shapes and sizes, from small flakes to large bumpy nuggets.
