The effect of operating conditions on density stratification in …
The operating conditions in a mineral jig can influence both stratification kinetics and the stratification profile achieved at equilibrium. In the past, however, studies on stratification in jigs have focused either on one or the other; equilibrium studies have been conducted to investigate the quality of stratification achievable, while kinetic studies have been undertaken …

Jig
Depending on the pulsation source, jigs can be generally categorized as: (1) Diaphragm jig uses the reciprocating motion of the rubber diaphragm to generate pulsating water flow, so as to allow minerals to be layered and separated based on their density (Fig. 1). (2) Piston jig uses the up-and-down reciprocating motion of the piston to allow the separation …
