Faculty Civil Engineering and Geosciences Department Structural Engineering Date 2012-12-31 Abstract Post-consumer steel scrap is often hand picked for contaminants such as copper to meet specifications of steelmakers. If the hand sorting capacity exceeds 20 tons scrap/h the efficiency generally becomes problematic, leaving 50% of the copper contaminants in the steel product. In response, new technologies are emerging that facilitate hand sorting of these types of scrap. Advantages are increased revenues, expanded plant capacity and higher and more consistent steel product quality. Proposed is a shape-sensitive magnetic separator that pre-sorts scrap into two products. One product is a bulky thinwalled steel fraction of high purity and the other a volumetrically small flow of relatively heavy parts including the contaminants. The concentrated contaminant product is amenable for effective sorting by hand pickers or for sensor sorting, but could also be sold directly to specialized sorters that extract the copper. Detailed results for the magnetic sorter are reported for mid-sized IBA scrap.
