Gold panning is a gravity concentration process in which a large plastic pan and water are used to separate minerals according to their density Gold is a very dense material pure gold has a density of g / cm3 so gold will be sink to the bottom of the pan while much lighter sand grains are washed off during the panning process Panning first removes the lightest sand grains such as
