Technological Developments in Jig Separation and Approaches to Advance in Separation

Abstract

Jig separation is an ancient technology in mineral processing and it is still in widespread use. In recent years many kinds of varieties on jig separation have been developed and applied to process fine particles and solid waste. The authors reviewed the technological development in jig separation and discussed how innovations occurred, relating to hand jigs used from the 16^th century, and jig separators developed in the 20^th century, moving screen, fixed screen, and rotating screen types. Recently developed jig separators for processing fine particles, larger particles and plastics are reviewed including the Rom jig, centrifugal jigs by Altair and Kelsey, and the packed column jig. Newly developed jig separators by the authors, RETAC, Hybrid and Reverse jigs, are introduced discussing the principles and applications behind the developments.
