A novel technique for the separation of cast and wrought aluminum alloy scrap is described. This technique, developed by the Bureau of Mines, exploits differences in hot ductility between cast and wrought aluminum. Tests are in progress to demonstrate its use for upgrading mixed aluminum scrap into recyclable grades of wrought and cast alloys. This paper describes (1) process development studies using conventional heating, fragmentizing, and screening equipment and (2) process improvements to enhance commercial development.
