Title: "CONTROL OF JIG SEPARATORS", ABSTRACT The density of the material in the jig bed is measured in consecutive short segments over the jig cycle, the time period of each segment being not greater than one-tenth the cycle time of the jig to determine, the density signature or profile of the jig. By controlling the operating parameters (e.g. inlet and outlet value opening and closing, underbed flow rate discharge gate position and jig working air pressure) of the jig, the density signature or profile is maintained within a control envelope for efficient stratification of the mineral.
