Jigging is a density-based separation technique consisting of the vertical oscillation of a granular bed, resulting in its stratification followed by separation of light and dense products [9]. The bed motion is driven by water or air pulses, being the first case called hydraulic (or water) jigging and the last case called dry (or air ...

In all studies, a concentrate of concrete particles of about 90% was reached, demonstrating that the jigging is a feasible process to treat Inert CDW. Most of the concrete particles concentrated can be used as coarse aggregate in new concretes. They consist of coarse aggregates present in demolished concretes.
Crushing, a form of comminution, one of the unit operations of mineral processing. Mineral processing is the process of separating commercially valuable minerals from their ores in the field of extractive metallurgy.

Jigging for concentrating minerals is based exclusively on the differences in density of the particles. The elementary jig (Fig. 13.29) is an open tank filled with water. A thick bed of coarse heavy particles (ragging) is placed on a perforated horizontal jig screen. The feed material is poured from the top.
For the coarse jig (-25 mm +8 mm) the maximum feed rate is 80 t/h/m width, for the medium jig (-8 mm +3 mm), 50 t/h/m width and for the fine jig (-3 mm +1 mm), 30 t/h/m width. The maximum feed rate would be influenced by the percentage of near density particles. Near density in this case means the mass percentage of material in the feed …
