Hydraulic mining

A miner using a hydraulic jet to mine for gold in California, from The Century Magazine January 1883

Gold miners excavate an eroded bluff with jets of water at a placer mine in Dutch Flat, California sometime between 1857 and 1870.

A man leans over a wooden sluice. Rocks line the outside of the wood boards that create the sluice.

Hydraulic mining, or hydraulicking, is a form of mining that uses high-pressure jets of water to dislodge rock material or move sediment. In the placer mining of gold or tin, the resulting water-sediment slurry is directed through sluice boxes to remove the gold. It is also used in mining kaolin and coal.
