Electronic waste contains valuable metals enclosed in material compounds or alloys. At present, recovering these metals needs sophisticated and energy-consuming processes. Engineers from Iowa State University, USA, developed a process to recover pure metals from waste by combining controlled oxidation and relatively low temperatures.
