Abrégé

The invention relates to a method for separating, in batches, a mixture comprising granules of at least two materials, comprising the following successive steps for each of the batches: introducing a batch into a fluidizing chamber (40) defined by a reactor (16) and obtaining an introduced batch (38), the granules of the batch being initially at rest, starting fluidization and obtaining at least one fluidized bed (18) in the fluidizing chamber, the fluidization being achieved by way of at least one ascending stream of fluid (42) that puts at least a fraction of the granules of the introduced batch into suspension, the fluidized bed being charged via the triboelectric effect, modifying the stream of fluid (42) and discharging at least 90% by mass of the introduced batch from the fluidizing chamber, passing the fed out batch in one or more electric fields intended to separate the discharged batch.

Abrégé

A device for triboelectric charging of a mixture of granules of different materials, the device having a charging chamber with walls delimiting an inner space. The walls define a granule inlet and a granule outlet, the granule inlet and the granule outlet being separated from one another relative to an elevation direction. A blowing device is arranged suitable for generating, in the inner space, an air flow suitable for allowing the granules in the chamber to form a fluidized bed, and a plurality of grids are positioned in the chamber, the grids being suitable for blocking the passage of the granules, the grids forming a set of baffles in the inner space between the granule inlet and the granule outlet.
