Oxidised gold deposits: Relationships between …

Many oxidised gold deposits exhibit features which strongly suggest an interplay between geo‐chemical processes and movement of the water‐table. Geochemical processes involving the dissolution of gold‐silver and gold‐tellurium alloys, and precipitation of high‐fineness gold (low Ag) in transition zones, neck‐oxide and lateral oxide zones can take place both above and below the ...

Topic 5: Mining Methods-Part I-Surface mining

Placer deposits are concentrations of heavy minerals, usually within loose alluvium that can easily be excavated and washed. Placer minerals such as gold, tin, and tungsten minerals, are of relatively high value, but the value of the placer gravel itself may be very low, often less than a dollar per cubic yard. For deposits of such low grade to be worked they must be near water, on or near the ...

Eolian Gold Deposits - Treasure Talk - Minelab

Eolian placers are a special type of residual gold deposit that prospectors should be interested in because the gold is shallow and richly concentrated - a condition well suited to exploitation with a metal detector. Eolian means formed by wind, and these deposits form in flat, arid areas where wind, not water, is the chief force that concentrates the gold, removing fine particles of clay and ...
