	Hydraulic mining, or hydraulicking, is an efficient way to mine placer deposits of gold. In this procedure a stream of high-pressure water is directed against a bank of alluvial deposits. The stream undercuts the bank and causes it to cave. As the bank disintegrates, the sediment forms a slurry with the water. This slurry is washed into a sluice, which can be either a wooden or metal box or a trough in the ground, and directed to a riffle box, which separates the gold from gravel. This whole process is driven by gravity.
