Abstract:

The levels of metal oxides in recovered electronic wastes obtained from electronic shops and dumpsites in Computer Village, Ogbunabali, Port Harcourt, Nigeria has been estimated. Electronic wastes such as radio panel, computer adapter, digital video disc (DVD) power, television (TV) panel, half TV panel, light emitting diode (LED) board, screen board, laptop adapter, laptop batteries and mobile phone batteries were dismantled, crushed, incinerated, pulverized, sieved, extracted and the metal oxides found in recovered e-wastes estimated using appropriate methods. The metal oxides obtained were ZnO, Fe2O3, NiO, CdO, PbO, Co3O4, CuO, Al2O3, AgO, Li2O and SnO2 from dismantled e-wastes. The highest percentage recovered was 48.72 % (Al2O3) while the least was 4.75 % (AgO). The highest percentage yield was 45.20 % (Fe2O3) while the least was 2.16 % (AgO). The recovered metal oxides could serve as important secondary sources of critical raw materials for diverse industries. The recovery processes could be used to recover valuable resources and mitigate environmental pollution.
