Detecting gold at California’s old hydraulic mines

Ground sluicing is basically a small scale, low pressure form of Hydraulic mining. In California, hydraulic mines have been a large source of gold to prospectors armed with metal detectors. It is not uncommon that small patches of bedrock or crevices in them were overlooked by the old timers and these have yielded some nice gold.

Hydraulic Mining - 911 Metallurgist

27/10/2016  In hydraulic mining, the breaking down of the gravel is so intimately connected with the extraction of the gold that a short description of the whole process is given. In this machine a jet of water under high pressure forces water, gravel, and boulders up an inclined plane, and delivers them all at the head of the sluice, which may be as much as 100 feet above bed-rock.

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.

1.1 PHASES OF A MINING PROJECT - ELAW

Bulldozers, dredges, or hydraulic jets of water (a process called ‘hydraulic mining’) are used to extract the ore. Placer mining is usually aimed at removing gold from stream sediments and floodplains. Because placer mining often occurs within a streambed, it is an environmentally-destructive type of mining, releasing large quantities of sediment that can impact surface water for several ...
