Abstract
The nonmagnetic rejects from shredding a typical automobile of the 1954–1964 decade contain approximately 38 kg of aluminum per metric ton. Urban refuse compositions vary greatly. Of two samples examined, one contained 2 kg of aluminum per metric ton and the other 12.5. Methods have been developed for recovering aluminum from both sources. The nonferrous metals in the nonmagnetic rejects from a shredded automobile can be concentrated into a 98 to 99 percent nonferrous metal product by a combination of air and water classification plus magnetic separation. Aluminum can then be separated from the other nonferrous metals by a sink-float process. A metallic nonferrous concentrate can be recovered from shredded urban refuse by combinations of air and water classification and magnetic separation. The aluminum can then be separately recovered by hand sorting or sink-float.
