Alluvial coltan jig introduction.

Jig machine is widely used in gravity concentration of tin, tungsten, placer gold, hematite ore, manganese, titanium, antimony, lead, tantalum, niobium and other minerals.

It belongs to deep trough separation operations(gravity jig equipment), using water as processing media, it depends on the difference of specific gravity between the minerals select and gangue to separate mine, the stroke and time of stroke is adjustable depend on different specific gravity of minerals.

Alluvial coltan jig working principle.

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.
