gold separation process in the mining

Gold being the heaviest element we typically encounter in a stream can be separated from lighter materials by various gravity separation methods Gold panning is the most common method used by small scale prospectors but larger mining equipment like gold dredges sluice boxes drywashers and many other types of equipment uses gravity separation to discharge lighter material while retaining gold
