I have intended this “Mining Main River Channels” as a quick introduction to how to get at the rich gold bearing materials that have up to now been inaccessible to 99.9% of all miners. There is nothing more frustration than knowing where lucrative gold deposits are and not being able to reach them. I offer my experiences with dredging main river channels as an option and not as the only ...

Finding Gold in a River - Gold Fever Prospecting - Mining ...

Flood gold can be found at the bottom of flood layers where heavy storms with enough force to move large amounts of gold will produce concentrations. Watch for layers of differing color, hardness and consistency. Some hard layers may masquerade as bedrock, so don't give up if the going gets a little hard. The shortest route idea applies here, also. Sharp bends may show good return in the ...

Sluice Box - Mine For Gold

Sluice boxes have been a part of gold mining since man first discovered that by replicating the river bed it was possible to trap gold in artificial rock crevices just as natural rock crevices accumulate gold. By mimicking a river bed it was possible to pass a much greater amount of material than it was to pan every shovelful by hand. Early sluice boxes were large heavy contraptions and ...

» The Basics of Successful Gold Mining-Part 1

The most important type of gold trap in river mining is called the “pay-streak”. Pay-streaks always form along the gold path where the river’s flow slows down on a large scale during a major flood storm. One example is the tail end of an inside bend in a river. Centrifugal force places most of the water pressure to the outside of the bend, leaving a low-pressure (low-velocity) area at ...

Hydraulic mining - Wikipedia

Hydraulic mining is a form of mining that uses high-pressure jets of water to dislodge rock material or move sediment. In the placer mining of gold or tin, the resulting water-sediment slurry is directed through sluice boxes to remove the gold. It is also used in mining kaolin and coal.. Hydraulic mining developed from ancient Roman techniques that used water to excavate soft underground deposits.
