Placer mining | Britannica
Placer mining, ancient method of using water to excavate, transport, concentrate, and recover heavy minerals from alluvial or placer deposits.Examples of deposits mined by means of this technique are the gold-bearing sands and gravel that settle out from rapidly moving streams and rivers at points where the current slows down.
This form of mining usually involves the extraction of secondary gold from placer deposits (alluvial, colluvial or elluvial), which can be liberated and treated using gravity methods. In the Guianas, the most popular form of small-scale gold mining is referred to as "land dredging", a combination of hydraulicking and suction dredging.

Osceola District Placer Deposits – Western Mining History
Placers were worked by hand until the early 1880s when the most important claims were consolidated and the Osceola Placer Mining Company was organized to work the ground by hydraulicking and sluicing. They constructed 2 ditches about 34 miles long at a cost of $200,000, and hydraulicking continued until about 1900.
