Successful gold mining is generally done in two steps: First is sampling or prospecting, ... Because we are limited as to how much gravel we can process as smallscale miners, we need to find highergrade deposits. This means we need to look for them, and this is where sampling comes in. When my partners and I first started gold dredging, we made the mistake of putting .
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 environmentallydestructive type of mining, releasing large quantities of sediment that can impact surface water for several miles downstream of the placer mine. ...
