Abstract: The invention relates to a sorting device and method for sorting granulated mass containing varied materials, such as granulated mass containing varied materials, such as granulated electronic scrap. According to the invention, the sorting device comprises a planar, elongated trough conveyor (1) having at least a first elongated and vertical edge (2, 3, 4); a feeding device (5) for feeding the mass into the first end (6) of the trough conveyor; a vibrator (9) provided with a motor (7) and an eccentric (8), whose rotation axis (10) is disposed in a plane deviating from the plane defined by the trough conveyor so that the mass proceeds obliquely forwards in the trough conveyor towards the first edge and second end (11); a first suction device (12) for removing the lightest surface portion of the mass near the edge, a guide (13) which is oblique with respect to the edge for bringing apart the mass flow from the edge; as well as a mechanical separator member (14) for dividing the mass flow into two parts.
