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 … It would be a very uncommon situation in which you could benefit from a closed loop providing flow to cylinders. Hydraulic motors are the typical actuators in a closed loop. They generally operate bi-directionally and must have some special features to be appropriate. A loop flushing valve and/or relief valves can be built into a closed loop motor.
