Notes:
Electrical and electronic equipment (EEE), e.g. printed circuit boards, containsubstantial amounts of metals, e.g. Cu, Pb and Sn. The objective of this work was toinvestigate the bioleaching of a material, originating from a technical waste processingfacility, as one possible way of a complete separation of the metals from the polymer carrier.During the leaching experiments the mechanism of the leaching process was investigated, andbiofilms and precipitates were analyzed by microscopical (SEM) and spectroscopical methods(EDX, XRF, XRD). The enhanced formation of exopolymer layers seems to promote theprecipitation of secondary mineral particles beneath and the sorption of particles from thesuspension on the layer surface
