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.
Aqueous surface mining methods can be subdivided in Placer and Solution and Includes:. Placer: concentrations of metals such as gold, titanium, silver, tin and tungsten are washed from within an alluvial deposit. Hydraulic mining: "Hydraulicking" applies high pressure water spray to excavate loosely consolidated or unconsolidated material into a slurry for processing.
