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
