Apparatus (10) and method for separating contaminating particles from an incoherent mass of woody material. The apparatus (10) comprises a separation chamber (11) into which the incoherent mass is introduced, first blowers (3 0) associated with the separation chamber (11), to deliver a first flow of a ir in a direction substantially transverse to the direction of fall of the i ncoherent mass, and to divert the direction of fall of materials with at lea st a first specific weight from materials with a second specific weight, and dividing members (12, 12a) disposed inside the separation chamber (11), in order to define different passage channels (13). The apparatus (10) comprise s aspirators (16) associated with the first blowers (30), to perform a furth er separation on the materials with first specific weight. The apparatus (10 ) comprises second blowers (31, 32) disposed so as to perform a third separa tion on a first part of the materials already separated by the first blowers (30).
