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.

Fig 2 Principle of the jigging process. Though jigs are simple in operation, the jigging process as a whole is rather complicated and strongly influenced by several interrelating factors (interacting variables or parameters). These factors are directly associated with one or more of the sub-processes into which the jigging process can be …

Gold processing - Mining, Concentrating, Refining: The nature of the ore deposit determines the mining and mineral processing techniques applied. Oxide ore deposits are frequently of such low grade (e.g., 3 to 10 parts per million) that extensive mineral processing cannot economically be justified. In this case they are merely shattered by …

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.

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 ...
