Hydraulic Mining. Historic Gold Mining Methods of

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 gravels.

The environmental effects from the hydraulic mining

The gold-mining industry generates an enormous amount of waste compared to its product: The 2,402 tons of gold produced in 1997 resulted in 725 million tons of waste, which was contaminated with metals, acids, and solvents, according to World watch institute.

15 Historic Photographs of the Hydraulic Gold Miners

Hydraulic mining became the primary way to recover large amounts of gold by the late-1800s. While normal placer mining techniques like panning and sluicing worked well in the rivers, there were many areas with ancient river gravels that were high above the current water flow. These could only be mined profitably with hydraulic mining. Water []
