High capacity separation of metals from auto shredder residue

Systems and methods for separating materials and recovery of valuable materials such as from end-of-life vehicles and appliances are disclosed. Vehicles are shredded and resulting pieces are dropped into a fluidic separator that separates the shredded vehicle scrap into heavier pieces and lighter pieces. The fluidic separator separates the bulk of the more valuable metals of the non-metals. The fluidic separator, which may be used for separating many kinds of mixtures of pieces of varying specific gravity, comprises a fluid-filled container in which the pieces and the fluid are stirred so that pieces of specific gravity greater than that of the fluid tend to sink and pieces of specific gravity less than that of the fluid tend to float.

Recovery of valuable components from a waste stream

A process for separating components of a waste stream. In one embodiment, the process includes providing shredded material in a form of particles each having a size of less than 2 inches. The particles of shredded material are separated based on size into a plurality of streams. Each of the plurality of streams is separated, based on density, into a first substream of greater density and a second sub stream of lesser density. Brittle components of each first substream are pulverized, leaving metallic components in sheet form. Metallic components are separated from the first substream after the pulverizing. The process can be utilized to recover metals from automobile shredder residue, such as copper, aluminum, and precious metals.
