Jigging is a type of gravity concentration method which manifest itself in the form of vertical expansions and contractions of a particle bed caused by a pulsing fluid.
In modern water jigs, the original basket was replaced by a compartmentalized vessel equipped with a sieve (or screen) to support the particle bed, mechanical pulsation devices were introduced, and operation became continuous. The general scheme of most industrial jigs consists of a container divided into two compartments, one of them corresponding to the separation chamber where feed particles are located on a supporting sieve and through which the water performs its oscillatory motion(Ambrós, 2020).
