Technological advancement and the accelerating growth of waste electrical and electronic equipment (WEEE) pose major challenges for resource recovery, particularly of metals embedded in printed circuit boards (PCBs). This study evaluates the effectiveness of flotation for the selective separation of metals from the non-metallic fractions of PCBs. Flotation experiments were conducted under various reagent regimes (different types and dosages). The investigation covered both the physicochemical properties of PCB feed material and the influence of process parameters on metal recovery. Results demonstrate that flotation can enhance the recovery of valuable metals while simultaneously minimizing material losses and mitigating environmental impacts, fully supporting circular economy principles. The work underscores the need to optimise technological parameters and to integrate flotation with other PCB recycling stages, thereby fostering more sustainable electronic waste management strategies.

Postęp technologiczny i przyspieszony wzrost ilości zużytego sprzętu elektrycznego i elektronicznego (ZSEE) stanowią poważne wyzwanie dla odzysku zasobów, zwłaszcza metali wbudowanych w płytki drukowane (PCB). Niniejsze badanie ocenia skuteczność flotacji w selektywnym oddzielaniu metali od frakcji niemetalicznych PCB. Eksperymenty flotacyjne przeprowadzono z różnymi reżimami odczynników (różne rodzaje i dawki). Badania obejmowały zarówno właściwości fizykochemiczne materiału wsadowego PCB, jak i wpływ parametrów procesu na odzysk metali. Wyniki pokazują, że flotacja może zwiększyć odzysk cennych metali, jednocześnie minimalizując straty materiałowe i łagodząc wpływ na środowisko, w pełni wspierając zasady gospodarki o obiegu zamkniętym. Praca podkreśla potrzebę optymalizacji parametrów technologicznych i integracji flotacji z innymi etapami recyklingu PCB, wspierając w ten sposób bardziej zrównoważone strategie gospodarowania odpadami elektronicznymi.
