Abstract
Separation of metallic particles from non-metallic particles of processed solid waste such as garbage to obtain a metallic concentrate, including use of such separation as the mid-step in a process which begins with homogenizing and magnetically treating components of the waste and ends with isolating the metallic concentrate as a high-purity metal fraction, for example, high-purity aluminum.
