This paper describes studies conducted by the U.S. Department of the Interior, Bureau of Mines, to achieve its goal of developing methods for increased recovery and utilization of valuable constituents in a wide variety of domestic and industrial wastes. In this particular study, 36 units of obsolete military electronic equipment were disassembled by hand to determine their composition. Although this equipment is normally classified as low-value irony aluminum, data were obtained that indicated the potential for a higher value classification. The electronic units were classified as to precious metals, copper, iron, and aluminum contents, and scrap values were estimated.
