The first integrated treatment of the aluminum recycling process, this book details the collecting, sorting, and separating of scrap aluminum as well as the processing and upgrading equipment used. It first describes aluminum alloys, the various "mines" where aluminum scrap is found, and the procedures that differentiate scrap aluminum from other materials. Subsequent chapters survey the furnaces used for remelting the recovered scrap and the refining techniques that improve its purity and quality. The book also discusses the economics of scrap recycling and outlines the structure of the recycling industry. The final chapter addresses unique environmental and safety challenges of recycling operations.
