Hydraulic mining encompasses hydraulicking, sluicing, and educing. Hydraulicking is the process of breaking up material and suspending it in a slurry. This is often done by using a large water cannon called a giant or monitor. The process of moving the slurry is called sluicing. Educing is the process of introducing the slurry into an enclosedMonitors (giants) at a hydraulic mine. The mine was worked nearly every season from 1855 to at least 1942. It produced over $1.25 million from 1855 to 1927. A nest of 24 undercurrents along the line of sluices at a hydraulic mine. Coarse boulders are removed by the grizzly.
