Jigging is an ancient but mature coal washing technology by gravity. It has more than 110 years history since the application of air jigging machine. However, because the theoretical research of jigging coal washing technology is still wandering at the hypothesis stage, it also seriously relies on operator's experience and skill, which results into no publicly recognized and uniform jigging ...

Hybrid-Jig separation experiments were carried out using the batch type TACUB jig (R&E Co.) with a 135mm long, 145mm wide, and 320mm high separation chamber. An outline of the Hybrid-Jig is shown in Fig. 1. An aeration diffusion tube was installed under the screen (particle bed) andanairpump(GEX,NewLungGX700N-2)wasconnected

A new type of jig called the hybrid jig was developed to address this limitation. The hybrid jig works by combining the principles of gravity separation and flotation, and could separate materials with similar SG as long as their surface wettability properties are different (Fig. 1b) [].Separation occurs due to the attachment of bubbles to more hydrophobic plastic particles …
