A gold mining dredge is a floating machine that uses a suction hose and pump system to vacuum up gravel, sand, and silt from riverbeds or stream bottoms. The material is then processed through a sluice box or recovery system to separate gold from waste material.
Dredges are especially effective at recovering fine gold and can operate continuously, making them far more efficient than traditional panning or sluicing.

| Type | Size (Horsepower) | Ideal For |
