(PDF) Copper recovery from spent ammoniacal etching solutions

Improved methods are required for the recycling of waste printed circuit boards (WPCBs). In this study, WPCBs (1–1.5 cm2) were separated into their components using dimethyl sulfoxide (DMSO) at 60 °C for 45 min and a metallographic microscope was used to verify their delamination. An increased incubation time of 210 min yielded a complete separation of WPCBs into their components, and ...
