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 gravels.
