Hydraulic mining monitor (nozzle) in San Francisco, CA ...

Hydraulic mining became the largest-scale, and most devastating, form of placer mining. Water was redirected into an ever-narrowing channel, through a large canvas hose, and out through a giant iron nozzle, called a "monitor." The extremely high pressure stream was used to wash entire hillsides through enormous sluices.

Hydraulic mining

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 enclosed ...

Hydraulic Mining - CPRR Photographic History Museum

Hydraulic Mining in California. By Craig E. Crouch, Rocklin, California . Hydraulic mining uses jets of water to break down gold-laden gravel banks and to wash the material through gold-separating devices (sluices and under-currents). It was one of the dominant forms of the California gold mining industry from the mid s until 1884, when it was halted by federal injunction.

Hydraulic mining originated out of ancient Roman techniques that used water to excavate soft underground deposits. Its modern form using pressurised water produced by a monitor came about in the 1850s during the California Gold Rush. FDP’s monitors project a concentrated jet (for maximum energy impact) to erode the tailings in sections.
