STATE OF THE PRACTICE OF SEDIMENT MANAGEMENT IN …

Sluicing is one of the more often used sediment-management techniques, but depends upon the existing structure of the dam and can cause adverse impacts to the downstream environment if not carefully monitored. Density current venting is seldom-used due to its reliance on the existence and surveying of a density current; however, it has been shown to be effective under certain circumstances ...

Hydraulic mining - Wikipedia

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. It is also used in mining kaolin and coal.. Hydraulic mining developed from ancient Roman techniques that used water to excavate soft underground deposits.

The basic sluicing techniques could be applied not only to alluvial/eluvial gold, but to any mineral with a high specific gravity found naturally weathered from its parent rock. They were used in Cornish tin mining up until the 14 th and 15 th centuries, and were used in New Zealand's brief tin mining activity on Stewart Island (discussed further below in Comparative Analysis).The earliest ...

There are several techniques and processes by which gold may be extracted from the earth. Placer mining Placer mining is the technique by which gold that has accumulated in a placer deposit is extracted. Placer deposits are composed of relatively loose material that makes tunneling difficult, and so most means of extracting it involve the use of water or dredging. Panning Gold panning is ...

Sluicing for Gold - Getting Started

Gold Sluicing Sluicing is the use of a "sluice box" in a creek or river to separate gold from gravel. (See our sluice kit below for a quick and easy way to get started with sluicing for gold.) A sluice box is a metal, wood, or plastic channel that has "riffles" and other devices in it …

Placer mining | Britannica

In sluicing or hydraulicking methods, a slightly sloping wooden trough called a box sluice, or a ditch cut in hard gravel or rock called a ground sluice, is used as a channel along which gold-bearing gravel is carried by a stream of water. Riffles placed transversely along the bottom of the sluice cause the water to eddy into small basins, retarding the current so that gold may settle and be ...

Mining - Mining - Placer mining: Placers are unconsolidated deposits of detrital material containing valuable minerals. The natural processes by which they form range from chemical weathering to stream, marine, and wind action. Typical minerals recovered in placers are gold, tin, platinum, diamonds, titaniferous and ferrous iron sands, gemstones (rubies, emeralds, and sapphires), and abrasives ...
