Beneficiation and Characterization of Detrital Zircons …
Kelsey reported that to reduce the Al 2O3 content to acceptable levels in the zircon product from kyanite-containing minerals, a Kelsey jig will probably be required, as the spirals alone will be unable to make a satisfactory separation between the two minerals [7]. There are many approaches to recover zircon by flotation [8-15]. Abeidu has a ...
Modelling the Kelsey Centrifugal Jig
Abstract. 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 ...
