Abstract
A system and method for decoating a scrap coated metal in a leach solution uses direct measuring of the corrosion potential of the scrap metal in the system to determine the progress of the decoating process and end the process when the scrap is decoated. Corrosion potential measurements are made using a working electrode comprising more than one piece of scrap coated-metal within the system. The decoating system and method may include a system for recycling leach solution.
