Apr 23, 2014· California Hydraulic Gold Mining Wikipedia, the free encyclopedia: Hydraulic mining, or hydraulicking, is a form of mining that uses highpressure jets of water to dislodge rock material or move sediment. In the placer mining of gold or tin, the resulting watersediment slurry is directed through sluice boxes to remove the gold. Hydraulic mining originated out .
Hydraulic mining was done extensively throughout California and other gold districts during the mid 1800''s. Although devastating to the environment, this gold mining method allowed miners to process massive amounts of gravel and recover gold from bench .

What is Placer Gold Mining? ... but this is slow, backbreaking work. To speed up the process they use the flow of water through wooden troughs called sluice boxes. In the bottom of the box a series of riffles, like shallow fences, agitate the slurry of water and gravel, encouraging small particles of gold to fall out of solution (again because ...
The hydraulic goldmining process used during the Californhttia Gold Rush and in many developing countries today contributes enormous amounts of sediment to rivers and streams. Commonly, accompanying this sediment are contaminants such as elemental mercury and cyanide used in the gold extrac

Gold Mining Methods . Placer Mining. The stereotypical grizzled goldrush prospector panning for gold was searching for placer gold, or gold deposited in a waterway. Placer mining takes a variety of forms, including panning, sluiceboxing, hydraulic mining, and dredging.
Gold Mining Plant is mainly mined from land surface or river or underground. Has various types of gold raw material: alluvial gold/placer gold/sand gold/river gold/ gold tailing, etc. The main process includes feeding, washing, sieving, rough separation, final concentration, and refining.
On the other hand, gold mining had established a broad network of dams and flumes, and the use of water power was at the core of much innovation in the years immediately following the initial gold rush, including hydraulic mining projects that washed whole mountains away and clogged rivers and the San Francisco Bay with mud.

Hydraulic Gold Mining is the cheapest form of gold mining is that in which the precious metal can be removed from its associated impurities—such as clay, gravel, sandstone and iron—and collected, entirely by the agency of water and mercury, with a minimum of manual labour.
Hydraulic mining, or hydraulicking, is a form of mining that uses highpressure jets of water to dislodge rock material or move sediment. In the placer mining of gold or tin, the resulting watersediment slurry is directed through sluice boxes to remove the gold.
Hydraulic mining and its legacy is an important part of California history and should be properly documented for future generations.

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 goldmining technology. The process of hydraulic mining, which became popular in the 1850s, caused irreparable environmental destruction.

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.
Figure 2: Simplified diagram showing the hydraulic remining of tailings. It can be noted that the use of hydraulic mining for tailings can be to either reprocess the waste, mine the waste as a product, or for moving of the tailings to a more suitable location.
The Mining Process. 1. Mining – open pit and underground. ... Some of the harder areas require blasting to loosen the rock prior to excavation by hydraulic diggers. Dump trucks haul the rock to the primary crushers in the open pit or to the ore stockpiles from underground. ... This process removes 93% of the gold and 70% of the silver.
