Copper Removal Methods From Steel — A Critical Assessment

In this study, different existing methods to remove alloyed and coated copper from steel are being investigated and compared. None of these methods have been scaled up industrially so far. Characterization of industrial steel scrap will indicate in which forms and quantities copper is present. Based on environment, economics and process efficiency, the most promising techniques will be selected. The study will focus on ways to bring the process efficiency to the level required for industrial application, by better understanding of the reaction kinetics. Possible removal of other undesired elements from the scrap will be taken into account as well.
