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 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 at Slough Creek Water would be carried to the mining site via canals and ditches where it would go into a hose. The beginning of the hose was larger and higher than the other end which would have a pipe attached to it, so the weight of the water going into the hose would force it out the other end at great pressure.

Big nozzles, called "hydraulic giants," shot powerful streams of water against a pre-historic river bed (now the bank of the stream) to expose and wash down gold-bearing gravel, which then was sluiced to recover the gold. This method, brought to Idaho in the 1860's, remained in use until recent economic changes made gold mining unprofitable.
