Hydraulic mining Wikipedia

A miner using a hydraulic jet to mine for gold in California, from The Century Magazine January 1883. 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.

Mining History: Hydraulic Mining News From The Diggings

Mar 06, 2017 Hydraulic mining was a natural progression from ground sluicing. Rather than shoveling gold bearing gravel into the sluices, mining companies could shoot high pressure jets of water to dislodge and direct earth. Pressure was created by tapping water sources at higher elevations. The water would travel through gradually narrowing pipes, building

Gold mining Wikipedia

Bronze Age gold objects are plentiful, especially in Ireland and Spain, and there are several well known possible sources. Romans used hydraulic mining methods, such as hushing and ground sluicing on a large scale to extract gold from extensive alluvial (loose sediment) deposits, such as those at Las Medulas.Mining was under the control of the state but the mines may have been leased to

Mining and Refining Process

Before mining can commence the land needs to be cleared of timber and vegetation. Alongside this process may be the collection of seeds and/or saplings, for inclusion in a seedbank, which will form the basis of post-mining revegetation of the site. Next the top soil is removed and is usually also stored for replacement during rehabilitation.
