Hydraulic Mining in California. By Craig E. Crouch, Rocklin, California Hydraulic mining uses jets of water to break down goldladen gravel banks and to wash the material through goldseparating devices (sluices and undercurrents). It was one of the dominant forms of the California gold mining industry from the mid1850s until 1884, when it

In Ancient Rome, many different hydraulic applications were developed, including public water supplies, innumerable aqueducts, power using watermills and hydraulic mining. They were among the first to make use of the siphon to carry water across valleys, and used hushing on a large scale to prospect for and then extract metal ores.

- Underground hydraulic mining
- Hydraulic mining is a form of mining that uses highpressure jets of water to dislodge rock material or move sediment. In the placer mining of gold or tin, the resulting watersediment slurry is directed through sluice boxes to remove the gold. It is also used in mining kaolin and coal. Hydraulic mining originated out of ancient Roman techniques that used water to excavate soft underground deposits. Its modern form, using pressurized water jets produced by a nozzle called a quot;monitorquot;, came about">

Hydraulic mining was a form of mining that used water to dislodge rock material or move sediment. Typically, intense jets of water were pressurized in an evernarrowing downward channel or hose and aimed at a hillside or riverbank, shearing off huge amounts of land and breaking it apart, washing the resulting debris into a huge sluice that extracts the gold from it.
