Abstract
An integrated process for recovering metal from nonmagnetic auto- shredder reject scrap was investigated by the federal Bureau of Mines. The methods used were air classification, water elutriation, screening, magnetic separation, handpicking, and heavy-media separation. Metal recoveries in this process were projected at 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 that a facility designed to reclaim the reject scrap from 200 shredded automobiles daily could be profitable. Total investment in this plant was estimated at $321,000; the discounted rate of return before taxes was 53 percent.
