The mineral particles form a bed layer on the jig. Due to the forced vibration of the transmission mechanism, periodic vertical alternating water flow is formed in the jig box. Under the action of rising water, the bed layer is loose, and the ore particles are gradually stratified according to the density, particle size and shape.

Dry processing Dry Jigging of Coal
1 Introduction. There are a number of advantages for upgrading coal with dry jigging technology, most notably the lack of process water, which eliminates the need for fines dewatering and slurry confinement. Dry jigging eliminates the product moisture penalty associated with wet processing of thermal coals. Particulate emissions are virtually ...

However, a drying process used for this purpose can be costly at mineral processing plants. Instead, the authors aim to assess if the single-step spray coating application, i.e., coating without drying, can result in (i) the formation of superhydrophobic particles and (ii) their separation at jigging.
