Hydraulic Mining Historic Gold Mining Methods of California
Hydraulic Mining was a gold recovery method that was used during many of the gold rushes around the world during the 1800’s It was used extensively in California's Mother Lode county during the famous gold rush there One of the problems that the early California gold miners faced with basic placer mining was the amount of manual labor that was required to process the gravelsNov 24, 2004· Hydraulic Mining in California By Craig E Crouch, Rocklin, California Hydraulic mining uses jets of water to break down goldladen gravel banks and to wash the material through goldseparating devices (sluices and undercurrents) It was one of the dominant forms of the California gold mining industry from the mid1850s until 1884, when it was halted by federal injunctionHydraulic Mining CPRR Photographic History Museum
