Hydraulic mining was used in the gold-fields of northern Spain, which was conquered by Augustus in 25 BC. The alluvial gold-mine of Las Medulas was one of the largest of their mines. It was worked by at least 7 long aqueducts, and the water streams were used to erode the soft deposits, and then wash the tailings for the valuable gold content. [citation needed] Modern

15.10.2019Reservoir: Hydraulic systems usually use a reservoir to hold excess fluid and power the mechanism. It is important to cool the fluid, using metal walls to release the heat generated from all the friction it encounters. An unpressurized reservoir can also allow trapped air to leave the liquid, which helps efficiency.

08.04.2002Hydraulic mining, or just hydraulicking, was a method of gold mining originally invented by the Romans in Spain.Rather than using human labor to dig gold out of the hills, powerful jets of water were sent out from holding tanks as much as 800 feet above the mining site. The jets broke up the ground and exposed the gold-bearing rocks a lot more quickly than
