WERKWIJZE VOOR HET TERUGWINNEN VAN BRUIKBARE MATERIALEN UIT AFVALMATERIAAL DAT METALEN EN NIET-METALEN BEVAT.

摘要

A process and apparatus for recovering useable materials from discarded scrap material, such as junked automobiles, is disclosed in which non-ferrous metals are separated from non-metals in a hydrocyclone using water as the aqueous separating medium. A particulate scrap/water suspension is injected into the cylindrical area of the hydrocyclone and a predominently non-metal-containing portion is removed from an overflow area of the cyclone while the non-ferrous metal containing portion is removed from the apex area of the cyclone. If required, the scrap material is preferably pulverized prior to treatment and is subjected to a ferrometallic separation operation if such metals are present.
