Gold mining

Gold mining consists of the processes and techniques employed in the removal of gold from the ground. There are several techniques by which gold may be extracted from earth and rock:

Gold panning

Gold panning is a manual gravimetric technique of sorting. Wide, shallow pans are filled with sand and fine gravel that is thought to contain gold. Water is added and the pans are shaken, sorting the gold, by density, from the rock and other undesirable material. The gravel is typically removed from streambeds, often at a bend in the streambed, where the weight of gold causes it to settle out of the streamflow. These concentrations of gold found in streams or dry streambeds are called placer deposits.
