ABSTRACT:
A device for removal of solid materials from the beds of bodies of water and the separation and capture of materials having a relatively high specific gravity from lighter solid material. The device is particularly suitable for the extraction of gold from alluvial material. The device is small and lightweight and generally comprises a pipe having an open inlet end and an open outlet end. The pipe has a first opening and a second opening that communicate with a container attached to the pipe. A suction force is applied along the length of the pipe so that water and materials from the bed of the body of water enter the pipe. That material having a relatively high specific gravity is collected within the container.
