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.
Mining History: Hydraulic Mining News From The Diggings
Nov 12, 2020#0183;#32;First developed as a modern technique in 1853, hydraulic mining was implemented as a means of sifting through rocks and sediment to find traces of gold ore. The usual application was to construct paths and canals that would free water from the higher mountain ranges and store the collected water in ponds located several hundred feet above the terrain that was to be mined.
Aug 11, 2018#0183;#32;But hydraulic mining was still widely used in placer gold mines on Alaska in the early 20 th century. Today, hydraulic gold mining is only rarely practiced on an industrial scale, but gold mines on Alaska sometimes use it. It survives mostly in artisanal form in remote, undeveloped and largely unregulated areas of the world.
Hydraulic mining was first developed in 1853, and implemented as a means of sifting through rocks and sediment to find traces of gold ore. The usual application was to construct paths and canals that would move water from the higher mountain ranges, and store the collected water in ponds located several hundred feet above the area that was to be mined.
Hydraulic Extraction, for excavating and logistics of coal or other materials, by means of water. Hydraulic Discharge, to direct discharge of surface water from the saturated zone and drainage. Mineral Processing, for gravel and sand lifting to the drainage level in the gold mine, where the water pressure creates a powerful suction in a dump hopper and caries the gravel and sand to the processing plant.
After the boardsluice, with its various adjuncts of rifflebars, stone bottoms, copper plates, and so forth, the next instrument of importance for gold mining during the California gold rush, is the hydraulic hose, used to let water down from a considerable height, and throw it under the pressure of its own weight against the paydirt, which is thus torn down, broken up, dissolved and carried into the sluice
In this method, a high pressure hose was used to direct a violent stream of water at the slopes and cliffs containing the terrace gravels and their load of gold. The loosened sediment would be washed over a set of riffles constructed out of bedrock. At intervals,

Sep 18, 2013#0183;#32;Hushing was also used during the California Gold Rush, where it evolved into hydraulic mining. In hydraulic mining, the basic principles are the same as hushing. Except instead of building a reservoir to contain the water, watersources were diverted into highpressure streams, then into canvass hoses that allowed miners to blast hillside gravel into largescale sluice boxes.
Hydraulic mining was used widely in the Californian gold rush, and involved breaking down alluvial deposits with highpressure jets of water. Hard rock ores have formed the basis of the majority of commercial gold recovery operations since the middle of the 20th century where open pit and or subsurface mining techniques are used. Once the ore is mined it can be treated as a whole ore using a
Mar 06, 2017#0183;#32;California Gold Rush. Hydraulic Mining as we know it was first used in 1853 outside of Nevada City, California by Edward Matteson. He used canvas hoses to redirect water and dislodge gravel. As the more easily accessible gold deposits in California were depleted, miners generally had two choices: hard rock mining or hydraulic mining.
The first use of this method is credited to Edward Mattison in 1853 who supplied the water through a rawhide hose to a nozzle he carved out of wood. Later miners upgraded their hoses to metal or the more desirable canvas, and the nozzle soon became iron.
