Abstract
Air and water classification systems have been developed by the Bureau of Mines for separation and recovery of metallic, glass, and combustible fractions from shredded urban refuse. Samples from two different types of shredders and three different urban locations were separated by air classification, magnetic separation, screening, and water elutriation to recover potentially useful products. More than 92 percent of the metals were recovered in a clean iron product contaminated only by adhering coatings or entrapped materials, and 97 percent of the combustibles were recovered in a 97-percent combustible product. Cleaning of the preliminary 97-percent combustible fraction from one sample produced a 100-percent combustible product containing 98 percent paper. Retreatment of the noncombustible fraction produced a relatively clean glass product.
