Various methods of metal recovery from nonmagnetic auto-shredder reject scrap including air classification, water elutriation, screening, handsorting, and heavy media separation were investigated. Projected metal recoveries in an integrated process are 39 percent copper and copper alloys, 53 percent aluminum, 96 percent iron, and 98 percent zinc die-cast. An economic evaluation of the conceptual process indicated profitable operation of a facility designed to separate daily the reject scrap from 200 shredded automobiles. Total investment in this plant would be $321,000, and the discounted rate of return before taxes would be 53 percent.
