Gravimetric mineral processing device and method for its use

Abstract

The invention disclosed and claimed herein is a device for processing minerals and a method for its use, which device and method employ gravimetric principles to separate values in a feedstock from gangue, thereby allowing recovery or concentration of the values. The invention includes a table that receives and holds the feedstock, a chassis for supporting the table, and a mechanism for imparting a specific motion to the table, the motion being referred to as “compound cyclic,” which is a reciprocating, rectilinear, to-and-fro motion parallel to or coincident with the working axis of the table, combined with a simultaneous, continuous, and smooth vertical up-and-down motion that eliminates vertical jolting, jarring, or bumping.

Dependencies are inferred from the claim text.
