Hydraulic mining is a large-scale form of placer mining. Placer mining was the earliest form of gold mining in the foothills of the Sierra Nevada Mountains in northern California. Placer mining generally entailed searching for geologically ancient alluvial deposits (former stream beds). The classic image of the old prospector squatting next to

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.

recovery and concentration of gold. In 1852, a French-speaking Canadian miner named Anthony Chabot bypassed the need for ditches and flumes by hooking up a canvas hose and directing the water flow at the ore supply. When his partner, Edward Mattison, increased the water pressure by adding a nozzle to the hose, hydraulic mining was born.

The geomorphology of modern Trinity River is the product of remarkable human impacts to the flow and sediment regimes. Virtually nothing is known about the river prior to the first discovery of gold in 1848. The Trinity River experienced 110 years of hydraulic mining from 1860 to 1970, a time period nearly four time as long as hydraulic mining in the Sierra Nevada Mountains. Hydraulic mining

The Mining Process. 1. Mining – open pit and underground. To define the ore from the waste rock, samples are taken and assayed. Assay results are used to mark out areas of ore and waste rock, which are mined separately. Some of the harder areas require blasting to loosen the rock prior to excavation by hydraulic diggers.

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.

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.
