Separator unit for gold mining assembly

摘要

An improved rotatable separator unit for gold or other ore separation is provided which gives enhanced ore recovery and can be installed on a mobile frame for transport to a mine site. The separator includes an upright, preferably frustoconical, ore-receiving bowl equipped with a plurality of generally horizontal vertically spaced apart ribs secured to the inner face of the bowl and extending inwardly therefrom in a "stair step" fashion; a central stationary conduit pipe is also provided for introduction of material into the bowl, along with powered means for rotation of the bowl about an upright axis. In particularly preferred forms, the separator is provided with a plurality of circumferentially spaced, stationary, obliquely oriented baffles located within the bowl and adjacent the inner edges of the bowl ribs for creating turbulence at the regions of the ribs and facilitating separation of the ore from undesired debris such as relatively large rocks.
