Hydraulic Mining Equipment

Hydraulic Mining. Where it is practicable, this is the simplest and most inexpensive method of placer mining. The mechanical equipment requirements consist only of pipe lines and giants. One feature, however, that is frequently overlooked in hydraulic mining is the matter of dumping facilities. This should always receive careful consideration.

Hydraulic Mining - CPRR Photographic History Museum

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, Mining Techniques, Underground Mining ...

Hydraulic Mining. Hydraulic mining, or hydraulicking, is a type of mining that uses water to displace rock material or move deposit. Formerly, the use of a huge volume of water had been urbanized by the Romans to take out overburden and then gold-bearing debris as in Las Médulas of Spain, and Dolaucothi in Britain.

Tailingsfo Hydraulic Mining of Tailings

This posed a problem for the hydraulic operation which was solved by having two mining areas to allow mining, drying and then rock removal. Dredging of the material in the dams would have caused damage to the mechanical equipment and pumps, also dry load and haul was considerably more expensive than hydraulic mining.

Hydraulic Gold Mining - mineralexpert.org

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.

Sluicing | mining | Britannica

In hydraulic mining …moving the slurry is called sluicing. Educing is the process of introducing the slurry into an enclosed circuit. In the hydraulic mining of gold the rebounding stream of water and mineral fragments is directed into sluices in which the gold settles behind baffles but the lighter waste matter is washed…

Hydraulic mining was also used during the Australian gold rushes where it was called hydraulic sluicing. One notable location was at the Oriental Claims near Omeo in Victoria where it was used between the 1850s and early 1900s, with abundant evidence of the damage still being visible today.

Mining History and Geology of the California Gold Rush

Hydraulic Mining: In 1853, the first successful hydraulic nozzle was brought to bear on the terrace gravels. 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.

Massive damage from hydraulic mining. June 29, 2011 By John Putnam 2 Comments. Located just above where the Yuba and Feather Rivers meet, and once part of John Sutter’s vast holdings, Marysville quickly became a debarkation point for miners on their way to the gold fields from San Francisco.

Yuba Goldfields, California - earthobservatory.nasa.gov

Mining companies moved from the valley floor into the Sierra Nevada foothills, where miners blasted gravel hillsides with high-pressure jets of water—a process called hydraulic mining. After the miners extracted gold in long wooden sluices, they dumped the gravel back into the mountain valleys.

The Malakoff Diggins - California's Largest Hydraulic Mine

The Malakoff Diggins were the largest hydraulic mine in California. The California gold rush of 1849 brought thousands of miners to the Yuba River and pretty much every other river or creek in the state. With the extensive mining that followed the gold rush, it didn’t take very long for the easiest placer deposits to become exhausted.

Hydraulic Gold Dredging

The old hydraulic-mining sluices, in which grizzlies and undercurrents played such an important part, and the early pick-and-shovel telescope-boxes, used even now in some fields, show that, in order to save gold directly, the current must be below that required to move coarse gravel, since otherwise the gold will go with the gravel to the tail ...

Calisphere: Environmental Impact in the Gold Rush Era

The Gold Rush, positive for California in so many ways, had a devastating effect on the state's environment. Many of these problems were directly related to gold-mining technology. The process of hydraulic mining, which became popular in the 1850s, caused irreparable environmental destruction.
