Modelling the Kelsey Centrifugal Jig

An empirical model of the Kelsey Centrifugal Jig is presented. The model describes the partition of feed material to the jig concentrate, taking account of the main jig operating parameters: g -force, ragging characteristics and stroke length and of the material properties of the feed. The model has been tested against the laboratory-scale jig separation of tungsten slime tailings. The effect of changing the jig ragging was predicted. The model has been used in the design of a wolframite tailings retreatment plant.
