Sawtooth
wave jig is revised and manufactured, based on the stratified theory and the adequate analysis of other conventional jigs. The jigging pulsation curve----produced by sawtooth wave jig----is in
the shape of sawtooth wave which makes upward water flow quicker than downward water flow. The feature that upward time is shorter than downward time solves the problem that time and action of
upward/downward water flows. This breakthrough dramatically amplifies the loose degree and mitigates suction action, which facilitates precipitation of coarse ores and improves ore recovery
rate.
