Hydraulic mining - Wikipedia

Hydraulic mining 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.. Hydraulic mining developed from ancient Roman techniques that used water to excavate soft underground deposits.
