OverviewMethodsHistoryStatisticsGold ore processingBusinessAdverse effectsSafety

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 Wide, shallow pans are filled with sand and gravel that may contain gold The pan is submerged in water and shaken, sortin
