In this study, high voltage electrical pulses were utilized to process waste printed circuit boards to cost effectively liberate metal and nonmetal materials. Relative mass ωiand particles content ηiindexes were defined to assess the stripping effect produced by high voltage electrical pulses breakage. For relative mass level in the 0–10% range, in the −6+3 mm fraction, particles content accounted...
With technological innovation and intense marketing, more and more electric and electronic equipment wastes (e-wastes) are being generated. Printed circuit boards (PCBs) are fundamental components of electronic wastes, which consist of both valuable metals and hazardous materials. An efficient method to recycle metals is an important measure to eliminate or avoid heavy metal hazard and realize resource...
