Abstract

L'invenzione riguarda un procedimento ed un dispositivo per separare materiali sintetici in un bacino di flottazione (2) con un liquido di determinata densità specifica. Per separare i differenti materiali sintetici con una densità specifica superiore od uguale ad 1, oppure con una densità specifica inferiore ad 1, è previsto che i materiali, privati di sostanze estranee grossolane, al di sotto della superficie del liquido vengono addotti con minore velocità di afflusso e prelevati per mezzo di un dispositivo di sollevamento sulla superficie (4) del liquido. Eventualmente in tal caso si possono prelevare ulteriori sostanze estranee con una densità specifica sostanzialmente inferiore a quella del liquido, tramite un ulteriore dispositivo di sollevamento (11).Con questo tipo di adduzione si evita una salita dei
