Abstract
Methods and systems for sorting mixed metal scrap may first determine a sorting attribute of each article of metal scrap, and subsequently mark each article with a machine-readable or visually identifiable mark according to the sorting attribute. The articles of mixed metal scrap can be sorted along a high throughput conveyance using a series of sensors to scan the articles for the machine-readable marks, and rapidly sorting marked articles to appropriate sorting destinations based on detecting the machine-readable marks, and without requiring repeat identification by metal analyzers at the sorting step.
