2015-7-1 · Hydraulic Mining in California. By Craig E. Crouch, Rocklin, California . Hydraulic mining uses jets of water to break down gold-laden gravel banks and to wash the material through gold-separating devices (sluices and under-currents). It was one of the dominant forms of the California gold mining industry from the mid-1850s until 1884, when it was halted by federal injunction.

Hydraulic Mining - Yuba-Sutter - LocalWiki

2021-11-9 · 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 ever-narrowing 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.
