摘要: Abstract This research aims to expand the body of information that researchers require before starting electronic waste (E-waste) recovery experiments. With this purpose, basic metal contents, alkalinity, polymer components, iron magnetic separation, priority and economic values different types printed circuit boards (PCBs) were investigated. The selected wastes computer PCBs (CPCBs), CPCBs with wires, mobile phone (MPPCBs), television (TVPCBs), fax machine (FPCBs), copy (COPCBs) central processing units (CPUs). These E-wastes prepared in three fraction sizes F1 FPCBs > MPPCBs > COPCBs > TVPCBs > CPCBs. Accordingly, FPCBs COPCBs determined as high value for recovery. In addition, Cu, Ag Sn respectively found be most metals should recovered from PCBs. Finally, pH analysis samples demonstrated E-waste alkalinity is due presence alkaline not plastics.
