Abstract: When galvanized steel scrap is recycled, zinc containing EAF dusts are produced. The dominant recycling route for these dusts is the Waelz process, which produces a Zn rich dust suitable for Zn metal recovery. The residue of the Waelz process is used for landfilling or aggregates.nbsp; Recently several alternative processes have been proposed and some were also industrially implemented. Limited work has been done however on the recovery of iron from the slag and the use of high calorific value wastes to also include energy recovery.
The aim of the current project is to investigate the potential in developing a pyrometallurgical treatment of EAF dusts making use of wastes with a high calorific value and generating a ZnO material suitable for Zn recovery, liquid metallic iron and a slag to be used in a high value application.
