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

Mercury Use in Hydraulic Mining In a typical sluice, hundreds of pounds of liquid mercury (several 76lb asks) were added to rifes and troughs to enhance gold recovery. The density of mercury is between that of gold and the gravel slurry, so gold and goldmercury amalgam would sink, while the

Mercury Usage in Gold Mining and Why It Is a Problem. Jul, how mercury is used in gold mining first, mercury is mixed with the materials containing gold a mercurygold amalgam then is formed because gold will dissolve in the mercury while other impurities will not the mixture of gold and mercury is then heated to a temperature that will vaporize the mercury, leaving behind the gold

Mercury contamination from gold mining Mercury has been used for centuries as an inexpensive and easy way to collect gold. The process begins when miners pump a mixture of water and sediment from a riverbed into a trough, where the sediment can be suspended into a slurry a technique known as hydraulic mining.

The vast majority of mercury lost to the environment in California was from placergoldmines, which used hydraulic, drift, and dredging methods. At hydraulic mines, placer ores were broken down with monitors (or water cannons, fig. 1) and the resulting slurry was directed throughsluices and drainage tunnels, where goldparticles combined with liquid mercury to form goldmercury amalgam.

MercuryFree Gold mining Technologies613 . When conducting hydraulic mining, some gold miners distribute large quantities of mercury on the pit floor, believing that the mercury will move through the ore to capture all the gold particlesThe turbidity of the slurry in the sluice boxes creates floured mercury that is also lost with the tailings.
